Taxes in South Africa: A guide for Americans and green card holders

Americans living in South Africa face a dual-tax system, which makes US expat tax in South Africa a year-round compliance issue. For the 2025–2026 tax year, that means navigating South African Revenue Service (SARS) rules alongside IRS filing requirements.

For many US expats in Cape Town, Johannesburg, and Gqeberha (formerly Port Elizabeth), understanding how the two systems interact is the first step to staying compliant and avoiding double taxation.

At a glance:

• US citizens and green card holders in South Africa may still need to file a US tax return.
• South African income may also need to be reported under SARS rules for the 2025–2026 year (1 March 2025 to 28 February 2026).
• Cape Town, Johannesburg, and Gqeberha are major hubs for US expats in South Africa.
• Tax relief options such as the Foreign Earned Income Exclusion or foreign tax credits may help reduce double taxation.
• Additional reporting forms like Form 8938 and FinCEN Form 114 may apply depending on your accounts, assets, and investments.

At Taxes for Expats, we’ve been helping US citizens and green card holders in South Africa file their taxes for over 8 years. In our country guides, you’d find expert knowledge of how the South African taxation system works alongside US obligations. So, contact us today and get on the right side of the IRS.

US expat tax obligations in South Africa

If you're a US citizen or green card holder living in South Africa, you are required to file a US tax return regardless of your residence status. For the 2025 tax year, filed in 2026, the FEIE limit is $130,000. The $132,900 limit applies to 2026 income, filed in 2027. If you’ve paid South African taxes on that income, you may also qualify for the Foreign Tax Credit (FTC) to avoid double taxation.

Besides these, US expats in South Africa must also be aware of other forms, such as FBAR (Foreign Bank Account Report) and Form 5471 (for foreign corporations). These must be filed if you have foreign accounts or a substantial interest in foreign entities. Failure to file these forms can lead to penalties of $10,000 or more per form.

Who qualifies as a tax resident in South Africa?

Many American expats ask about the tax residence South Africa (183 Days Rule); however, whether or not you're considered a tax resident depends on two main tests:

• Ordinarily Resident Test: You are deemed a tax resident if South Africa is your primary home or "ordinary residence" (i.e., you maintain a regular presence in the country).
• Physical Presence Test: You meet this test if you are in South Africa for more than 91 days in the current year, more than 91 days in each of the previous five years, and a total of 915 days over the last five years.

In South Africa, tax residence is generally determined under either the ordinarily resident test or the physical presence test. A person who is not ordinarily resident in South Africa may still become tax resident if they are physically present in the country for more than 91 days in the current tax year, more than 91 days in each of the previous five tax years, and more than 915 days in total across those five years.

NOTE! The “183-day rule for non-residents” is not the main South African tax residence test. In South Africa, the core residence framework for individuals is the ordinarily resident test or the physical presence test.

Where 183 days does show up is in other contexts, such as:

• treaty-based rules for some employment income of non-residents working in South Africa, and
• certain withholding tax/exemption rules.

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

For many US expats, taxation in South Africa becomes easier to manage once the SARS rates, rebates, and thresholds are clear. South African income tax rates for 2026 remain progressive, with the top rate at 45% for taxable income exceeding ZAR 1,817,000. The South African tax year ends on February 28 and is used to determine your tax liability.

South Africa tax brackets 2025/2026

Key takeaway: South Africa kept the same 18%–45% rate structure, but the 2026–2027 tax year raised the income brackets, which can reduce tax slightly at the same income level.

Use the latest SARS tax tables to compare rates, rebates, and thresholds across both years.

Tax rebates and thresholds

South Africa gives individual taxpayers age-based rebates that reduce the tax they owe. For the 2026 year of assessment (1 March 2025 – 28 February 2026), the primary rebate is R17,235, and for the 2027 year of assessment (1 March 2026 – 28 February 2027), it increases to R17,820. If your taxable income falls below the threshold for your age group, you generally do not pay South African income tax.

Key point: All three South African individual tax rebates increased for 2026–2027.

 

Key point: The tax threshold also increased for 2026–2027, including from R95,750 to R99,000 for taxpayers under age 65.

The South African expat tax exemption

The expat tax exemption South Africa can exempt up to R1.25 million of qualifying foreign employment income.

That means, South African tax residents who are employees working abroad may qualify to exempt up to R1.25 million of foreign employment income, provided they meet the statutory day-count tests.

This rule is crucial for dual-status taxpayers or those with South African residency, as it allows them to exclude up to ZAR 1.25 million of foreign income.

US-South Africa tax treaty and totalization

The US-South Africa tax treaty, often referred to as a Double Taxation Agreement (DTA), aims to prevent double taxation on income. This treaty allows US citizens and green card holders to offset taxes paid in South Africa against US tax liabilities.

NOTE! There is no Totalization Agreement between the US and South Africa, which means that Social Security taxes (FICA/UIF) may be owed in both countries for the same income. For more information on how this affects your Social Security obligations, learn what the US tax treaty covers.

Other taxes on individuals

South African income tax is only part of the picture for individuals. For the 2026 year of assessment (1 March 2025 – 28 February 2026) and the 2027 year of assessment (1 March 2026 – 28 February 2027), the other taxes expats should know are capital gains tax, estate duty, and transfer duty. For individuals, capital gains tax still works through a 40% inclusion rate, estate duty remains 20% to 25%, and transfer duty remains progressive from 0% to 13%.

Capital gains tax

South Africa does not charge a separate flat capital gains tax on individuals. Instead, 40% of a net capital gain is included in taxable income, and the maximum effective CGT rate for individuals and special trusts remains 18% in both 2025–2026 and 2026–2027.

• For 2025–2026, the main exclusions were a R2,000,000 primary residence exclusion, a R40,000 annual exclusion, a R1,800,000 small-business exclusion for qualifying disposals, a R10,000,000 small-business market-value cap, and a R300,000 year-of-death exclusion.
• For 2026–2027, those amounts increased to R3,000,000, R50,000, R2,700,000, R15,000,000, and R440,000, respectively.

Estate duty

Estate duty applies to the worldwide property of a person ordinarily resident in South Africa and to the South African property of a non-resident. For both 2025–2026 and 2026–2027, the rate is 20% on the first R30 million of dutiable value and 25% above R30 million, with a R3.5 million abatement.

Transfer duty

Transfer duty applies to property transactions that are not subject to VAT. SARS publishes transfer duty by effective date, not by year of assessment, so for 2025–2026 the relevant table is the one effective 1 April 2025, and for 2026–2027 the relevant table is the one effective 1 April 2026.

For 2025–2026, the tax-free threshold is R1,210,000, and the top rate is 13% for property values above R13,310,000.

For 2026–2027, SARS states there were no changes from last year, so the same R1,210,000 threshold and 13% top band continued.

South Africa corporate income tax

For the 2026 tax year, South Africa corporate income tax is set at 27% for both companies and branches. This represents a reduction from the previous rate of 28%. The tax system applies to corporations that are incorporated or effectively managed in South Africa. Branches of foreign corporations are taxed at the same rate of 27%.

• Residence: A company is tax resident in South Africa if it is incorporated there or if its place of effective management is in South Africa.
• Treaty override: A company is not treated as South African tax resident if it is exclusively resident in another country under an applicable tax treaty.
• Basis of taxation – residents: South African resident companies are taxed on worldwide income.
• Basis of taxation – non-residents: Non-residents are taxed only on South African-source income and on capital gains from South African immovable property or assets linked to a South African permanent establishment.
• Branches of foreign companies: South African branches of foreign companies are taxed on South African-source income at the standard 27% corporate tax rate.
• Taxable income: Corporate tax applies to profits, including trading income, passive income, and taxable capital gains.
• Deductions: Expenses incurred in the production of income are generally deductible when calculating taxable income.
• Dividends – domestic: Dividends received by one South African company from another South African company are generally exempt from corporate income tax.
• Dividends Tax: South Africa now applies Dividends Tax, generally at 20%, subject to exemptions and treaty relief where available.
• Secondary Tax on Companies (STC) is no longer the current system and should not be presented as still being phased out.
• Foreign dividends: Dividends from foreign companies may be taxable, but exemptions can apply, including where the South African company holds at least 20% of the shares and voting rights.
• Foreign dividend relief: If a foreign dividend is taxable, a foreign withholding tax credit may generally be available.
• Capital gains: Companies include 50% of net capital gains in taxable income, with tax then charged at the normal corporate income tax rate.
• Capital gains exemption: Gains on substantial foreign shareholdings may be exempt if the relevant conditions are met.
• Losses: Assessed trading losses may generally be carried forward, but loss carrybacks are not allowed.
• Surtax: No surtax applies.
• Alternative minimum tax: South Africa does not impose an alternative minimum tax.
• Foreign tax credit: Foreign tax paid on foreign-source income can generally be credited against South African tax on the same income, subject to limitations.
• Participation exemption: A South African resident holding company may qualify for a capital gains participation exemption on the sale of foreign shares if it meets the conditions, including at least 20% of shares and voting rights held for at least 18 months.

See: Form 5471: a guide for US taxpayers with foreign interests.

Controlled Foreign Company (CFC) rules in South Africa

Under South Africa's Controlled Foreign Company (CFC) rules, South African residents who hold more than 50% of the voting or participation rights in a foreign company are subject to tax on the foreign company’s income, unless an exemption applies. The tax paid in the foreign country may be used to offset the South African tax liability.

Taxation is based on a pro-rata share of the income earned by the CFC, which may be subject to tax in South Africa at the applicable corporate tax rate.

Other compliance rules include the General Anti-Avoidance Rules (GAAR), which prevent tax avoidance through non-compliant structures or transactions. The South African tax year for corporations is the same as their financial year.

Filing and compliance requirements

Companies must file their income tax returns annually, within 12 months of the company’s financial year-end. Provisional tax payments are made twice a year based on estimated tax liability, with an additional provisional tax return submitted if the first two payments do not cover the final tax amount.

Withholding tax

South Africa applies various withholding taxes to foreign entities or individuals, including the following:

• Dividends: 20% withholding tax rate on dividends. For US residents, the tax treaty rate reduces this to 15%.
• Interest: 15% withholding tax on interest paid to non-residents.
• Royalties: 15% withholding tax rate on royalties paid to non-residents, subject to reduction under tax treaties.
• Other Withholdings: 
  Entertainers and sportspersons: A 15% withholding tax is applied to gross payments for performances or activities in South Africa. When a non-resident sells immovable property in South Africa, the buyer must withhold a portion of the payment, depending on the seller's status (individual, company, trust).

Anti-avoidance rules

South Africa has anti-avoidance rules to prevent tax evasion, including transfer pricing and thin capitalization provisions.

Transfer pricing

South African taxpayers must follow arm's length principles for transactions with connected persons outside South Africa. If transactions between related parties are deemed non-compliant with these principles, the tax authorities may adjust the prices to reflect what independent parties would have agreed upon.

Thin capitalization

Thin capitalization rules limit the deductibility of interest on debt provided by a nonresident connected person to a South African company. South Africa no longer relies on a general 3:1 thin-capitalization rule as the governing standard.

Cross-border connected-party debt is instead tested under arm’s-length transfer-pricing principles, including whether the amount of debt and the interest terms are commercially supportable.

General anti-avoidance rules (GAAR)

GAAR provisions apply to transactions and structures that are primarily aimed at avoiding taxes through non-compliant means. These rules give the tax authorities the power to deny deductions or disallow transactions if they are deemed to have been undertaken with the principal purpose of avoiding tax liability.

South Africa VAT (Value Added Tax) rates

The standard VAT rate in South Africa remains 15% for the 2026 tax year. The VAT registration threshold has increased to ZAR 2.3 million per annum, effective from April 2026.

• VAT registration: Businesses with taxable supplies exceeding ZAR 2.3 million annually are obligated to register for VAT. Non-residents conducting business in South Africa must also register for VAT if they make taxable supplies.
• VAT filing and payment: VAT returns are generally submitted every 2 months, with businesses exceeding an annual turnover of ZAR 30 million required to submit returns monthly. Returns are due within 25 days after the end of the tax period, and full payment must accompany the return.

Important deadlines: SARS vs IRS

When filing taxes as an American expat living in South Africa, understanding the US expat tax in South Africa means tracking both SARS and IRS deadlines. While both tax authorities offer extensions, they have different due dates for filing and payment.

 

NOTE! For expats, calculating tax in South Africa also means checking whether relief or credits apply, and knowing the financial year end (February) because SARS and IRS deadlines do not align.
