South Africa taxes for Americans and Green Card holders

South Africa taxes for Americans and Green Card holders
Written by 

Americans in South Africa may have filing duties in both countries for the 2025 tax year. South African residents can be taxed on worldwide income, while US citizens and resident aliens apply US filing rules even while living abroad.

This guide covers employment income, investments, rental income, businesses, foreign accounts, capital gains, VAT, and filing deadlines. TFX in our guide on US expat tax guide details a broader US-side overview.

The 3 points below summarize how taxes in SA can affect Americans and green card holders:

  • Residency: South Africa generally taxes residents on worldwide income and non-residents on South African-source income.
  • Foreign income: Salary, business income, investments, and rent can require reporting depending on residence and source.
  • Dual filing: A US filing requirement is tested separately from the South African filing requirement.

The South African tax for expats framework therefore starts with two separate questions: where are you tax resident, and what income does each country have the right to tax?

Americans who own companies abroad should also review the US rules for foreign company tax reporting.

The IRS confirms that foreign income is generally included when determining a US citizen or resident alien’s federal tax obligations. See the IRS guidance on reporting foreign income while living abroad.

US expat tax obligations in South Africa

For 2025 returns filed in 2026, a US filing obligation depends on gross income, filing status, age, dependency status, and special filing triggers. A single filer under age 65 generally files at $15,750 of gross income.

Living in South Africa does not itself cancel US tax filing rules.

The following 4-step checklist helps coordinate tax in SA with US reporting:

  1. Determine South African residence. Check the ordinarily resident test and physical presence test.
  2. Identify taxable income. Separate employment, business, investment, rental, and other income.
  3. Test your US filing requirement. Use the 2025 Form 1040 filing thresholds and special filing rules.
  4. Coordinate relief. Compare the Foreign Tax Credit, FEIE, treaty provisions, and South African relief.

US taxpayers should also distinguish FBAR from FATCA reporting.

An FBAR is generally triggered when foreign financial accounts exceed $10,000 in aggregate at any point during the calendar year, not merely because an account exists.

For US income tax, the Foreign Tax Credit can offset qualifying foreign income taxes paid on income also taxed by the United States.

The South Africa expat tax analysis is therefore not a single tax calculation. The US and South African systems must be tested separately before credits or exclusions are applied.

The South African citizens working abroad tax rules are also separate from US citizenship-based filing rules. A dual US–South African citizen may therefore have obligations in both systems.

The IRS summarizes the US rules in its filing requirements for US citizens and residents abroad.

Do I file in both countries?

If you are a South African tax resident and also meet a US filing requirement, the answer can be yes. Filing in both countries does not automatically mean paying full income tax twice.

Based on our client scenario at TFX: A US employee living in Johannesburg earns a salary from a local employer and pays PAYE to SARS.

The salary can enter both tax systems. The US return may then use a Foreign Tax Credit or, if the requirements are met, the Foreign Earned Income Exclusion.

Based on our client scenario at TFX: A US contractor in Cape Town works for clients in three countries and receives no employee withholding.

The contractor may need South African provisional tax and US self-employment reporting, with treaty and credit rules reviewed separately.

For 2025 US returns, the IRS also introduced Schedule 1-A for four new deductions covering qualified tips, qualified overtime, qualifying vehicle-loan interest, and eligible seniors.

South Africa taxable income rules (and what counts for expats)

South Africa uses a residence-based system: residents are generally taxed on worldwide income, while non-residents are generally taxed on South African-source income. Taxable income is broadly gross income minus qualifying exemptions and allowable deductions.

The South Africa tax on foreign income therefore depends first on whether the individual is a resident.

The following 8 income categories commonly matter for US expats:

  • Salary and wages
  • Bonuses and taxable employment benefits
  • Stock or equity compensation
  • Self-employment and business income
  • Dividends
  • Interest
  • Rental income
  • Amounts qualifying for an exemption or deduction

Foreign dividends also create separate US reporting questions. See our guide to taxation of foreign dividends.

South African residents generally start with worldwide income, while non-residents focus on South African-source income.

Income type Typically taxable in South Africa? Notes for expats
Salary Yes Residence, work location, and treaty rules matter
Bonus Usually May need allocation to the work period
Stock compensation Often Timing and employment connection matter
Business income Yes Residence and source determine scope
Dividends Often Exemptions or dividends tax may apply
Interest Often Exemptions differ for residents and non-residents
Rental income Yes Net taxable rental income is generally relevant
Exempt amounts No, if conditions are met Each exemption has its own requirements

 

A US owner of foreign real estate should also coordinate South African treatment with the US rules for rental property on a US tax return.

The IRS distinguishes foreign earned income from passive income such as dividends, interest, pensions, and capital gains. See its explanation of what counts as foreign earned income.

Based on our client scenario at TFX: A US worker has R900,000 of salary and R240,000 of gross rent, with R80,000 of allowable rental expenses.

Before other deductions or exemptions, the rental result is R160,000 and the combined amount is R1.06 million.

Who qualifies as a tax resident in South Africa?

South African individual tax residence is determined first by ordinary residence and, if that does not apply, the physical presence test. That test requires more than 91 days in the current year, more than 91 days in each prior 5 years, and more than 915 days across those 5 years.

The South African living abroad tax position can change when a person ceases South African tax residence.

The following 2 branches determine domestic individual tax residence:

Branch 1 – ordinarily resident

Ask whether South Africa is the country you regard as your real, usual, or principal home and the place to which you naturally return.

For context on the separate US concept, see our bona fide residence test guide.

Branch 2 – physical presence

If you are not ordinarily resident, test all 3 SARS day-count conditions.

You must exceed 91 days in the current year, exceed 91 days in each of the 5 prior years, and exceed 915 days in total during those prior 5 years.TFX physical presence test guide explains the different US test used for the FEIE.

A person who meets the South African physical presence test can cease residence under that test after being outside South Africa for at least 330 continuous full days.

 

Pro tip
Do not use 183 days as a shortcut for South African tax residence. The domestic physical presence test uses 91 / 91 / 915, while 183 days appears in other tax rules.

 

A US remote worker who moves to South Africa for one short assignment may fail the 5-year physical presence history even after spending more than 91 days there.

A returning South African may be ordinarily resident even before building enough days to satisfy the physical presence test.

A person who meets both US and South African domestic residence rules should also review the US–South Africa treaty documents.

South Africa tax residency test flowchart

Use this 2-branch flowchart to test South African domestic residence before calculating worldwide income. A person who is ordinarily resident can be resident without meeting the 91 / 91 / 915 test, while a treaty tie-breaker can affect dual-resident treatment.

South Africa Flow Chart by Taxes for Expats

The following 4 notes help interpret the flowchart:

  • Ordinary residence is a facts-and-circumstances concept, not a fixed day count.
  • All 3 physical presence requirements must be met.
  • A continuous absence of at least 330 full days can end residence acquired under the physical presence test.
  • A tax treaty may need to be checked when both countries treat you as resident.

Residence is not the same as domicile. See our guide to country of domicile versus residence for further understanding. You can also compare the US tests in our guide to the bona fide residence and physical presence tests.

Taxation in South Africa: 2025–2026 SARS personal income tax rates

For the South African 2026 year of assessment, March 1, 2025 through February 28, 2026, personal income tax runs from 18% to 45%. The top tax rate in SA applies above R1,817,000 of taxable income.

South African income tax is based on taxable income, not gross receipts alone.

For comparison with US concepts, our MAGI guide explains how modified adjusted gross income works in the US system.

The US calculation remains separate. A qualifying taxpayer may use the Foreign Earned Income Exclusion, which has a $130,000 limit per qualifying person for 2025.

The 2026 South African rate schedule has 7 progressive bands from 18% through 45%.

2026 taxable income Marginal rate Tax before rebates Who it affects
R1–R237,100 18% 18% of taxable income Lower taxable income
R237,101–R370,500 26% R42,678 + 26% above R237,100 Lower-middle band
R370,501–R512,800 31% R77,362 + 31% above R370,500 Middle band
R512,801–R673,000 36% R121,475 + 36% above R512,800 Upper-middle band
R673,001–R857,900 39% R179,147 + 39% above R673,000 Higher earners
R857,901–R1,817,000 41% R251,258 + 41% above R857,900 High earners
R1,817,001+ 45% R644,489 + 45% above R1,817,000 Top band

 

The SARS rate is marginal. Entering a higher band does not cause all taxable income to be taxed at that higher percentage.

The IRS publishes separate US federal statistics and rates in its individual income tax rate data.

Income determination for individuals

For the 2026 South African year, taxable income can include employment, self-employment, passive, and rental income. Residents generally report worldwide income, while non-residents generally report South African-source income. Records should show both the amount and source.

The following 4 income buckets form a practical record-keeping hub:

  1. Employment income: Keep payslips, IRP5/IT3(a) data, employment contracts, bonus records, travel calendars, and evidence of foreign workdays.
  2. Self-employment income: Keep invoices, contracts, bank records, business expenses, and proof of foreign taxes. US freelancers can review our guide to filing taxes as an independent contractor.
  3. Passive income: Keep statements for dividends, interest, distributions, brokerage accounts, and foreign withholding.
  4. Rental income: Keep leases, rent statements, management fees, repairs, mortgage-interest records, and other deductible expense records.

See our foreign rental income tax guide for the US reporting side.

These 4 categories require different records even when they appear on the same annual tax return.

Category What is generally reviewed Records to keep
Employment Salary, bonus, benefits Payslips, contracts, tax certificates
Self-employment Gross receipts less allowable costs Invoices, receipts, bank records
Passive income Dividends and interest Broker and bank statements
Rental income Rent less allowable expenses Lease, statements, invoices

 

The IRS explains which forms can accompany Form 1040 when claiming the FEIE in its foreign earned income forms guidance.

Based on our client scenario at TFX: A salaried employee in Pretoria reports payroll income separately from investment income because each category has different supporting records. Another freelancer billing US clients keeps invoices and expense records even when payments arrive in a South African bank account.

South Africa tax brackets 2025/2026

The 2025/2026 South African individual schedule has 7 brackets, beginning at 18% and reaching 45% above R1,817,000. The income tax in SA calculation applies each marginal rate only to the portion of taxable income falling in that band.

For the 2026 year of assessment, the 45% rate begins only once taxable income exceeds R1,817,000.

Taxable income Rate Base tax at lower limit Example monthly income
R1–R237,100 18% R0 R15,000
R237,101–R370,500 26% R42,678 R25,000
R370,501–R512,800 31% R77,362 R35,000
R512,801–R673,000 36% R121,475 R50,000
R673,001–R857,900 39% R179,147 R60,000
R857,901–R1,817,000 41% R251,258 R100,000
R1,817,001+ 45% R644,489 R166,667+

 

Based on our client scenario at TFX: A taxpayer under 65 has R600,000 of taxable income.

Tax before rebates is R121,475 plus 36% of R87,200, or R152,867. After the R17,235 primary rebate, the amount is R135,632 before other credits.

Based on our client scenario at TFX: A taxpayer under 65 has R2 million of taxable income.

Tax before rebates is R644,489 plus 45% of R183,000, or R726,839. After the R17,235 primary rebate, the amount is R709,604 before other credits.

A marginal rate applies only to income within that bracket, not to all income from the first rand.

Tax rebates and thresholds

For the 2026 South African tax year, the primary rebate is R17,235. The tax threshold is R95,750 for someone under 65, R148,217 for ages 65–74, and R165,689 for age 75 or older.

A rebate reduces calculated tax. A threshold is the income level below which an individual in that age group ordinarily has no income tax liability after the applicable rebates.

The 2026 age-based rebates reduce tax after the bracket calculation.

Age band 2026 rebate Practical effect
Under 65 R17,235 Primary rebate
65–74 R26,679 total Primary + secondary
75+ R29,824 total Primary + secondary + tertiary

 

The 2026 tax-free thresholds rise with age because older taxpayers receive extra rebates.

Age 2026 threshold
Under 65 R95,750
65–74 R148,217
75+ R165,689

 

US filing thresholds are different. Our guide to the minimum income required to file US taxes explains the federal side.

The South African expat tax exemption

South African tax residents working as employees outside South Africa can exempt up to R1.25 million of qualifying foreign employment income if section 10(1)(o)(ii) applies. The rule requires qualifying foreign service and specific day-count conditions.

This rule is separate from the US Foreign Earned Income Exclusion.

The South African working abroad tax exemption applies to qualifying employment remuneration, not every type of foreign income.

The following 5 conditions are central to the South African exemption:

  • You remain a South African tax resident.
  • You are an employee rather than an independent contractor for the qualifying income.
  • The remuneration relates to services rendered outside South Africa.
  • You spend more than 183 full days outside South Africa during a qualifying 12-month period.
  • At least 60 of those days are continuous.

Qualifying remuneration can include salary, wages, overtime pay, bonuses, leave pay, and taxable benefits when the statutory requirements are met.

The exemption is capped at R1.25 million of qualifying remuneration.

Income above that cap is not automatically exempt from South African income tax.

NOTE! Bonuses and other payments covering both South African and foreign work periods may require allocation. The full payment should not automatically be treated as foreign service income.

US taxpayers comparing the two systems should also review Foreign Tax Credit versus FEIE. The IRS explains its separate US exclusion requirements in the Foreign Earned Income Exclusion rules.

For the 2025 US tax year, the FEIE maximum is $130,000 per qualifying person. The $132,900 figure applies to 2026 income, normally filed in 2027.

Based on our client scenario at TFX: A South African tax resident earns R1.5 million of qualifying foreign employment income and meets the day tests.

Up to R1.25 million may fall within the exemption. The remaining R250,000 stays in the South African tax calculation before other applicable items.

 

Pro tip
Keep a day-by-day travel calendar. Missing the 60 continuous days or the 183-day requirement can change the section 10(1)(o)(ii) result.

US–South Africa tax treaty and totalization

The United States and South Africa have an income tax treaty, but no US–South Africa Social Security totalization agreement is in force as of September 9, 2026. SSA currently lists 31 agreement countries, and South Africa is not one of them.

The treaty can allocate taxing rights and provide double-tax relief for covered income. It does not remove the need to examine US domestic filing rules.

For background, see our guide to US tax treaties.

The income tax treaty and a Social Security totalization agreement solve different problems, and South Africa has only the former with the United States.

Issue US–South Africa income tax treaty Totalization agreement
Income tax Yes No
Double-tax relief Can apply Not its purpose
Social Security coordination No Would coordinate coverage
Exists with South Africa? Yes No

 

The following 3 steps help when treaty relief may apply:

  • Identify the type and source of income.
  • Check the relevant treaty article and the saving clause.
  • Determine how the treaty position is disclosed on the US and South African returns.

TFX also explains how totalization agreements affect US expat taxes.

What the treaty does not do

The treaty does not automatically make foreign income tax-free. It also does not replace FBAR, FATCA, Form 5471, or other information-reporting rules when those rules apply.

Other taxes on individuals

For the 2026 South African year, income tax is only one part of the system. Capital gains can enter taxable income, estate duty can reach 25%, and transfer duty can reach 13% on qualifying property acquisitions.

The following 3 taxes are especially relevant to expats with assets or property:

  • Capital gains tax: applies through the income tax system when assets are disposed of.
  • Estate duty: can apply to a resident’s estate and to South African property of a non-resident.
  • Transfer duty: can apply when property is acquired in a transaction not subject to VAT.

For property disposals, read TFX guide to capital gains tax on foreign property. For cross-border estates, review our guide to estate taxes for expatriates.

Capital gains tax

South Africa does not levy individual CGT as a separate flat tax. For the 2026 year, 40% of an individual’s net capital gain is included in taxable income, producing a maximum effective individual CGT rate of 18%.

Common CGT events include disposals of property, shares, and business interests.

The following 4 events can matter for expats:

  • Selling South African or foreign real estate
  • Selling shares or investment assets
  • Disposing of a business interest
  • Certain deemed disposals when tax residence changes

Residents can face CGT on a broader range of worldwide assets.

Non-residents are generally exposed to CGT on specified South African assets, including South African immovable property.

Our guide to capital gains on a primary residence in the US and abroad covers the US side. You can also review the US rules for capital gains and losses.

For the South African 2026 year, the individual inclusion rate is 40%, while the annual exclusion remains R40,000.

Item 2026 tax year
Individual inclusion rate 40%
Maximum effective individual CGT rate 18%
Annual exclusion R40,000
Primary residence gain exclusion R2,000,000

 

The higher R50,000 annual exclusion and R3 million primary-residence exclusion apply from the 2027 year, not the 2026 year.

Based on our client scenario at TFX: An individual has a R500,000 net capital gain and no other capital transactions.

After the R40,000 annual exclusion, R460,000 remains. Applying the 40% inclusion rate puts R184,000 into taxable income before the marginal tax rate is applied.

US returns require foreign-currency conversion where amounts are denominated in rand. The IRS explains foreign currency and exchange rates.

Estate duty

South African estate duty is 20% on the first R30 million of dutiable value and 25% above R30 million. A R3.5 million abatement is allowed when determining the dutiable amount.

Residence can change the asset scope.

A South African resident’s worldwide property can enter the estate-duty calculation, subject to exclusions and deductions.

A non-resident is generally exposed on qualifying South African property.

The R3.5 million abatement applies before the 20% and 25% estate-duty rates are applied.

Person Assets potentially in scope Main expat issue
South African resident Worldwide property Cross-border estate exposure
Non-resident South African property Local property exposure
Estate over R30 million dutiable value Higher marginal estate-duty rate 25% applies above R30 million

 

Americans with inherited or foreign estate assets should also review the US rules for foreign inheritance tax and reporting.

Based on our client scenario at TFX: A South African resident dies while holding property in South Africa and investment assets in the United States.

Worldwide property may enter the South African estate-duty analysis, even though US estate-tax rules are tested separately.

Transfer duty

For property acquired on or after April 1, 2025, South African transfer duty is 0% through R1.21 million and rises through 6 bands to 13% above R13.31 million. SARS kept the same schedule from April 1, 2026.

Transfer duty is normally a buyer-side transaction cost.

It differs from CGT, which focuses on a seller’s gain from disposing of an asset.

Property up to R1.21 million has a 0% transfer-duty rate under the schedule effective April 1, 2025.

Property value Transfer duty
R0–R1,210,000 0%
R1,210,001–R1,663,800 3% above R1,210,000
R1,663,801–R2,329,300 R13,614 + 6% above R1,663,800
R2,329,301–R2,994,800 R53,544 + 8% above R2,329,300
R2,994,801–R13,310,000 R106,784 + 11% above R2,994,800
R13,310,001+ R1,241,456 + 13% above R13,310,000

 

Based on our client scenario at TFX: A buyer acquires qualifying property for R3 million.

Transfer duty is R106,784 plus 11% of R5,200, producing R107,356 before legal and other transaction costs.

Americans purchasing property abroad should review our guide to buying foreign real estate.

Our guide to foreign property taxes covers the separate US reporting considerations.

South Africa corporate income tax

South African companies with years of assessment ending on or after March 31, 2023 generally face a 27% corporate income tax rate. US owners can also have Form 5471, Subpart F, NCTI/GILTI-transition, or other US reporting depending on ownership and entity classification.

The South African tax rules for expats who own businesses must therefore be reviewed alongside US entity rules.

South African resident companies are generally taxed on worldwide income.

Non-resident companies are generally taxed on South African-source income and certain South African capital gains.

For entity-choice considerations, see our guide to business structures for expats.

The 27% corporate rate does not mean that an individual owner’s US reporting is limited to 27%.

Structure South African focus US owner focus
Individual business Personal taxable income Form 1040 and business schedules
South African company 27% company tax where applicable Entity reporting may apply
Foreign company with SA activity SA-source income or PE issues US ownership rules remain separate

 

A US shareholder should confirm both the entity’s South African position and the owner’s US reporting before relying on the company’s local tax rate.

Controlled Foreign Company (CFC) rules in South Africa

A foreign company can be a South African CFC when South African residents directly or indirectly hold more than 50% of participation rights or exercise more than 50% of voting rights, subject to statutory details and exclusions.

South African residents can then have attributed income under section 9D.

The following 4 checkpoints matter for an expat owner:

  • Is the company foreign for South African tax purposes?
  • Do South African residents exceed the 50% participation or voting threshold?
  • Does the owner hold a sufficient participation interest for attribution?
  • Does an exclusion or exemption apply to the relevant income?

US owners should separately review the US Controlled Foreign Corporation rules.

The following chain shows the basic exposure:

Foreign company

> 50% SA-resident participation or voting control?

Potential South African CFC

Section 9D attribution analysis

A US shareholder may also need to consider Subpart F income.

South African CFC status and US CFC status are separate tests. Meeting one does not automatically mean the other has been met.

Filing and compliance requirements

Companies generally submit an ITR14 within 12 months after the financial year-end. Provisional taxpayers normally make at least 2 advance income-tax payments, while US owners must separately check Form 1040 and international information forms.

The following 5 compliance items should be tracked:

  • South African annual company income tax return
  • South African provisional tax returns and payments
  • Financial statements and supporting records
  • US individual or entity information returns
  • Foreign account and asset reporting where applicable

US owners can use our expat IRS tax form checklist. Our guide to US tax forms for expats explains common international forms.

Company filing and provisional tax run on different schedules, so both must be tracked.

Task Who files Typical timing Notes
ITR14 South African company Within 12 months after year-end Annual company return
First IRP6 Provisional taxpayer Within 6 months of year start Estimated tax
Second IRP6 Provisional taxpayer By year-end Reconciles annual estimate
Optional top-up Eligible provisional taxpayer After year-end Can reduce interest exposure
US international forms US owner With applicable US return Depends on ownership and assets

 

The IRS explains where and when US citizens abroad file and pay.

Late or inaccurate South African provisional tax payments can produce interest or penalties. A late provisional payment can carry a 10% penalty under the SARS provisional tax rules.

Withholding tax

South Africa uses withholding taxes for several payments to non-residents. The domestic rate is generally 20% for dividends and 15% for interest or royalties, although exemptions or an applicable treaty can reduce the rate in the right circumstances.

The payer commonly withholds tax before the recipient receives the net payment.

That withholding can affect cash flow, but it does not always eliminate year-end reporting.

Our guide to foreign withholding forms explains the US-side documentation.

Domestic withholding rates can be reduced when an exemption or treaty provision applies.

Payment Payer action Domestic concept
Dividend Company or intermediary withholds Generally 20%
Interest to non-resident Payer withholds Generally 15%
Royalty to non-resident Payer withholds Generally 15%

 

Treaty rates must be checked by income type and ownership.

For example, the US–South Africa treaty does not impose one blanket 15% dividend limit for every shareholder situation.

Based on our client scenario at TFX: A US resident receives a South African payment after local withholding.

The gross income and foreign tax withheld should be reviewed separately when preparing the US return and any Foreign Tax Credit calculation.

The IRS notes that certain foreign-source payments do not require Form 1042-S. See its guidance on foreign-source income and Form 1042-S.

Anti-avoidance rules

South Africa applies anti-avoidance rules to cross-border arrangements, including transfer pricing, related-party debt, and GAAR. Section 31 governs affected cross-border transactions, while GAAR sits in sections 80A–80L of the Income Tax Act.

These rules matter when legal form and commercial substance do not align.

The following 3 areas deserve special attention:

  • Transfer pricing for cross-border connected-party transactions
  • Thin capitalization and related-party debt
  • GAAR for impermissible avoidance arrangements

A foreign company operating in South Africa may also create a permanent establishment.

Branches can raise separate issues covered in our guide to branch profits tax.

What to watch for: Related-party fees, loans, or transfers without commercial support can attract review even when the contracts are formally valid.

Transfer pricing

South African transfer pricing uses an arm’s-length standard for affected cross-border transactions. Section 31 can apply when connected parties price services, goods, loans, or other dealings differently from terms independent parties would have accepted.

The following 3 groups should pay particular attention:

  • Owners of foreign or South African companies transacting with related entities
  • Businesses charging intercompany management or service fees
  • Shareholders providing loans or transferring assets to related companies

US shareholders should also check Form 5471 reporting. Certain foreign-owned US entities may instead encounter Form 5472.

Transfer-pricing documentation should explain both the transaction and why the price is commercially supportable.

Transaction Documentation Why it matters
Management fee Service agreement and pricing support Shows service and arm’s-length price
Related-party sale Comparable pricing Supports sale value
Intercompany loan Loan agreement and credit analysis Supports principal and interest terms

 

Based on our client scenario at TFX: A South African company pays a related US company a management fee.

The fee should be supported by the services provided and an arm’s-length price rather than being set only to move profit between countries.

US international corporate rules changed for tax years beginning in 2026, so old GILTI terminology and calculations should not be carried forward without checking current law.

Thin capitalization

South African thin-capitalization analysis now sits within the section 31 transfer-pricing rules rather than a general 3:1 debt-to-equity safe harbor. Both the amount of connected-party debt and its financing terms should be commercially supportable.

The following 4 checks help owners with related-party loans:

  • Document why the borrower needed the debt.
  • Support the amount that an independent lender would have advanced.
  • Support the interest rate and loan terms.
  • Retain agreements, forecasts, and repayment evidence.

Warning: A historic 3:1 ratio should not be treated as a current automatic safe harbor.

An excessive loan amount or unsupported interest cost can be adjusted under the arm’s-length rules.

General anti-avoidance rules (GAAR)

South African GAAR can apply to an impermissible avoidance arrangement when the statutory section 80A requirements are met. GAAR is not a blanket rule against reducing tax; it targets arrangements with specified avoidance features.

The following 4 red flags deserve review:

  • Steps with little commercial purpose apart from the tax result
  • Circular or offsetting flows of funds
  • Rights or obligations that differ sharply from normal commercial terms
  • Structures whose legal form does not match their economic substance

TFX explains the distinction between tax avoidance and tax evasion.

A related discussion of lawful tax reduction versus evasion should be read in light of the specific law that applies to the transaction.

Based on our client scenario at TFX: A group inserts an entity with no staff or operating role solely between 2 related companies before a large payment.

The arrangement needs a commercial-purpose and substance review rather than relying on the extra legal entity alone.

Summary: Keep contracts, pricing support, board records, and evidence of business purpose for material cross-border arrangements.

South Africa VAT (Value Added Tax) rates

South Africa’s standard VAT rate remains 15% in 2026. From April 1, 2026, SARS is applying a R2.3 million compulsory-registration threshold and a R120,000 voluntary-registration threshold, subject to the 2026 legislative implementation described by SARS.

VAT is mainly a business issue rather than a personal income tax.

Individuals still bear VAT as consumers when it is charged on taxable goods or services.

The following 3 VAT points matter most:

  • Standard VAT is 15%.
  • Businesses crossing the compulsory threshold need to test registration.
  • VAT collected from customers is not the same as business income tax.

Our year-end financial checklist for expats can help organize business records.

Business owners should also review foreign business structures for expats.

The 15% VAT rate applies separately from the 27% corporate income tax rate.

VAT item 2026 position
Standard rate 15%
Compulsory registration threshold from April 1, 2026 R2.3 million
Voluntary registration threshold from April 1, 2026 R120,000

 

Who needs to care most? Business owners making taxable supplies in South Africa should monitor annual turnover and current SARS registration rules.

Important deadlines: SARS vs IRS

For 2025 income filed in 2026, the IRS regular deadline was April 15, 2026, while qualifying Americans abroad received an automatic extension to June 15, 2026. SARS non-provisional individual returns are due October 23, 2026.

SARS provisional individual returns are due January 22, 2027.

The tax for a South African working abroad can therefore involve deadlines in two calendar years.

The South African citizens working abroad tax calendar should not be copied from the IRS calendar because SARS and IRS filing seasons are different.

See our guide to foreign-country tax filing deadlines.

For the 2026 filing season, SARS and IRS due dates do not line up.

Authority 2026 deadline What it covers
IRS April 15, 2026 Regular 2025 federal filing/payment date
IRS June 15, 2026 Automatic filing extension for qualifying taxpayers abroad
IRS October 15, 2026 Extended filing date where Form 4868 rules are met
SARS October 23, 2026 Non-provisional individual filing deadline
SARS January 22, 2027 Provisional individual filing deadline

 

The IRS explains the automatic 2-month extension for taxpayers abroad.

Its rules for a further extension are covered in the additional extension guidance for Americans abroad.

An extension to file is not always an extension of every payment obligation. For further reading, see TFX explanation of tax extensions versus payment obligations.

The following 3 checkpoints can be used before a filing deadline:

  • 30 days before: collect income, foreign tax, account, entity, and residency records.
  • 15 days before: identify missing forms, elections, treaty positions, and extension needs.
  • 5 days before: confirm filing method, payment instructions, signatures, and attachments.

NOTE! Interest on unpaid US federal income tax can run from the regular April 15 due date even when a taxpayer qualifies for extra filing time.

SARS’s 2026 ITR12 also has expanded prefilled data and new residency-status questions. Taxpayers remain responsible for checking whether prefilled information is complete.

 

Pro tip
A non-provisional SARS filer has until October 23, 2026, while a provisional filer has until January 22, 2027. Identify the correct category before relying on either date.

Maximize your tax savings in South Africa: Get help with cross-border filing

US and South African tax relief must be applied to your actual facts. For 2025, that can include the $130,000 FEIE, Foreign Tax Credits, treaty rules, and South Africa’s R1.25 million foreign-employment exemption when each rule’s requirements are met.

TFX can help organize a filing that accounts for income, foreign taxes, accounts, and entities in both systems.

The following 3 issues commonly require cross-border review:

  • Choosing between or coordinating FEIE and Foreign Tax Credit treatment
  • Reporting foreign accounts, assets, rental income, or companies
  • Catching up when US returns or international forms were missed

Our guide explains when hiring an expat tax professional can make sense. You can also review our guide on preparing to save money on an expat tax return.

TFX has served more than 50,000 clients across 193+ countries, with US expat returns prepared by professionals familiar with international reporting.

FAQ

1. Do Americans living in South Africa still file US tax returns?

Yes, when they meet the applicable US filing rules. For 2025, a single filer under 65 generally has a $15,750 gross-income threshold, while special rules can require filing at lower amounts.

2. What is the 183-day rule in South Africa?

The 183-day figure is not the main domestic tax-residence test. Residence uses ordinary residence or the 91 / 91 / 915 physical presence test. More than 183 days is used in other rules, including the foreign-employment exemption.

3. Do South Africans working abroad pay tax in South Africa?

South Africans working abroad: tax depends on residence, income source, and available exemptions. A South African resident employee can qualify for the R1.25 million foreign-employment exemption if all section 10(1)(o)(ii) conditions are met.

4. Does South Africa tax foreign income?

Residents are generally taxed on worldwide income, subject to exclusions and relief. Non-residents are generally taxed on South African-source income. Foreign tax credits or treaty rules can reduce double taxation in qualifying cases.

5. What are the main SARS filing deadlines in 2026?

Non-provisional individuals generally have until October 23, 2026. Provisional individuals generally have until January 22, 2027. Auto-assessments ran from July 1 through July 12, 2026.

6. Are Cape Town tax rules different from the rest of South Africa?

No separate Cape Town tax system replaces national SARS income tax. A US expat living in Cape Town applies the same South African federal tax rules discussed in this guide, although municipal property charges and local fees can be separate.
