Iceland taxes for Americans: US expat tax guide

For the 2025 tax year filed in 2026, a US citizen moving to Iceland can face both US worldwide-income reporting and Icelandic tax once local residence or source rules apply. The key is to separate filing duties, tax residence, and relief for tax paid twice.

The following 3 points give the fastest picture:

• US citizens and green card holders generally keep US filing duties while abroad, even when Iceland also taxes the same income.
• Iceland generally treats a stay of 6 months or longer in a 12-month period as residence, with unlimited tax liability from arrival.
• US reporting may include Form 1040, FBAR, Form 8938, Form 2555, Form 1116, and entity forms depending on income and assets.

For 2025 income, the local system and the US system can overlap without automatically creating double taxation. US credits, exclusions, treaty rules, and the US–Iceland Social Security Agreement can coordinate different parts of the result.

Your Iceland tax position depends on residence, income type, and whether the same income is also taxed by the United States.

US citizens abroad remain subject to US worldwide-income rules. See our US expat tax guide and the IRS rules for US citizens and resident aliens abroad.

The US rule is tied to citizenship or resident-alien status, not where you live. Our guide to citizenship-based taxation explains why a move abroad does not end federal filing duties.

The following 4-item mini checklist covers the first facts to confirm:

• Count your Iceland days and determine whether you cross the 6-month residence threshold.
• List wages, self-employment income, pensions, investments, rent, and other income in both countries.
• Check foreign account balances for FBAR and Form 8938 reporting.
• Keep Icelandic tax assessments, withholding records, and proof of foreign tax paid.

A US citizen who moves to Reykjavík in June 2025 may become an Icelandic tax resident during 2025 if the stay reaches 6 months. Before relocating, the State Department’s Iceland country information is also useful for non-tax entry and country guidance.

Tax liability and residency rules

Iceland generally gives an individual limited tax liability when the stay is under 6 months in a 12-month period and unlimited liability when the stay reaches 6 months. For residents, worldwide income is generally taxable from the date of arrival.

The following 3-step residency check separates the main outcomes:

1. Under 6 months: You normally have limited Icelandic liability on Iceland-source income.
2. 6 months or longer: You generally become resident from arrival and report worldwide income in Iceland.
3. After departure: Former residents may remain fully liable for up to 3 years unless they prove tax residence elsewhere.

This Iceland test is separate from US resident-alien rules. See our guide to US tax rules for resident and nonresident aliens when US immigration or US tax residence is also at issue.

Based on our client scenario at TFX: an American arrives June 15, 2025, and remains through year-end. A stay reaching 6 months generally makes the person an Iceland resident from June 15, so worldwide income from that arrival date enters the Iceland analysis.

Based on our client scenario at TFX: a long-term resident leaves Iceland on August 31, 2025. Departure alone may not end unlimited liability because the 3-year former-resident rule can continue unless the taxpayer proves taxation in another country.

The Iceland residence test is not the same as the US bona fide residence test used for certain Foreign Earned Income Exclusion claims.

Keep a dated travel log. Crossing the 6-month threshold can change Icelandic liability from source-only income to worldwide income from the arrival date.

US expat taxes – Iceland

For 2025 income, Iceland taxation and US taxation can apply to the same taxpayer at the same time. US citizens and green card holders generally report worldwide income, while Iceland applies its own residence and source rules. Foreign tax credits can reduce overlapping income tax.

The key filing rule is that living abroad changes deadlines and relief options, but it does not automatically remove the US return.

 

The IRS states that qualifying taxpayers abroad receive an automatic 2-month filing extension, but interest on unpaid US income tax runs from the regular April deadline. A timely Form 4868 can extend filing to October 15.

FEIE timing is not limited to a timely original return. IRS rules permit an initial Form 2555 election on certain amended or late-filed returns, including some returns filed after the normal election window when regulatory conditions are met.

For Iceland, the 2026 individual return covering 2025 income had a March 13, 2026 deadline. The Iceland Revenue and Customs filing page also notes that people living abroad may still need to file for Iceland-source income or real estate.

A 2025 federal-law update raised the US standard deduction to $15,750 for single/MFS, $23,625 for HOH, and $31,500 for MFJ/QSS. These amounts apply to 2025 returns filed in 2026.

The following 5 filing areas are the core “what Americans in Iceland need to file” check:

• Foreign income: wages, self-employment income, pensions, interest, dividends, rent, and gains may be reported on Form 1040.
• Foreign accounts: FBAR applies when aggregate foreign accounts exceed $10,000 at any point in the year.
• Foreign retirement accounts: foreign pensions can affect Form 1040, FBAR, Form 8938, or other reporting depending on the plan.
• Foreign financial assets: For qualifying taxpayers abroad, Form 8938 starts above $200,000 year-end/$300,000 anytime, or $400,000/$600,000 on a joint return.
• Foreign entities or investments: additional information returns can apply to corporations, partnerships, trusts, or PFICs.

The IRS applies the higher Form 8938 thresholds only when the taxpayer meets its living-abroad test. The form is attached to the federal income tax return, unlike the FBAR.

Taxation in Iceland for 2025 income also follows a separate local return and assessment cycle. That calendar does not replace the US filing calendar.

Taxes in Iceland extend beyond personal income tax. Business owners can also encounter VAT and payroll charges, while property owners may face municipal property tax.

For account reporting, see how FBAR differs from FATCA reporting before assuming one filing satisfies the other.

For a US filer, the most relevant tax in Iceland is usually income tax that may qualify for the IRS Foreign Tax Credit.

Because the island taxes wages and investment income under different rules, the foreign-tax-credit category can differ by income type. Form 1116 should match the US category and the Icelandic tax actually paid.

 

 

The next section shows Iceland’s individual income-tax brackets and how payroll withholding works for 2025 income.

Taxation of individual income in Iceland

For 2025, Iceland's income tax on employment income uses 3 combined national and average municipal withholding brackets: 31.49%, 37.99%, and 46.29%. The Iceland tax rate is progressive for each monthly pay period, while private capital income is generally taxed separately at 22%.

For 2025 wages, the 3 Icelandic tax rates apply monthly after deductible pension premiums, with the personal credit then reducing the calculated tax.

 

The combined rates include national income tax plus an average municipal component. Actual municipal tax varies by municipality, so payroll and final assessment can differ from a simple national-rate comparison.

A resident is generally taxed on worldwide income from arrival, while a short-term nonresident is taxed on Iceland-source income. The following table shows the practical split.

The 6-month residence test changes the income base more than it changes the published 2025 wage brackets.

 

The following 3 payroll points matter most for employees and contractors:

• Employers withhold income and municipal tax from wages each pay period.
• A 4% mandatory pension contribution is generally deductible from wage income.
• Self-employed individuals can face payroll tax on presumptive employment income and separate business-income rules.

Americans working independently should compare local treatment with our guide on filing US taxes as an independent contractor.

Based on our client scenario at TFX: monthly taxable pay after pension deductions is ISK 600,000. The first ISK 472,005 is taxed at 31.49%, and the remaining ISK 127,995 at 37.99%, producing about ISK 197,260 before personal credit.

Statistics Iceland reported average regular monthly earnings of ISK 816,000 in 2025. The average income in Iceland was higher for full-time regular earnings at ISK 913,000, with a full-time median of ISK 826,000.

These Iceland tax rates are the 2025 payroll rates. They should not be mixed with the separate 22% capital-income rate.

For comparison, the top federal US marginal rate for tax year 2025 remained 37%. The IRS publishes the current federal income tax rates and brackets.

A qualifying US taxpayer may also use the Foreign Earned Income Exclusion. The 2025 FEIE limit is $130,000, but the exclusion and FTC cannot both offset the same income.

The tax rate in Iceland should always be matched to the tax year. The table above is for 2025 income, not the 2026 brackets that apply to income earned during 2026.

Taxable income for individuals

For 2025, Iceland generally treated wages, cash payments, benefits in kind, pensions, grants, business income, and investment income as taxable unless a specific rule excludes them. A 22% rate generally applied to private capital income, while employment income used the 3 wage brackets.

Definition: Taxable income is the amount Iceland includes in the tax base after applying the rules for the income category and permitted deductions.

The following 4 categories cover common receipts for Americans in Iceland:

• Earned income: salary, wages, bonuses, and presumptive employment income for self-employed work.
• Benefits in kind: employer-provided cars, housing, or other noncash compensation when taxable.
• Allowances and reimbursements: taxable unless an exemption or documented expense rule applies.
• Capital income: interest, dividends, rental income, and capital gains under separate rules.

Understanding earned versus unearned income also matters on the US return because FEIE applies to qualifying earned income, not ordinary investment income.

The following 2-way check helps classify common items:

• Usually taxable: salary, taxable fringe benefits, pension payments, business profit, dividends, interest, and taxable gains.
• Potentially exempt or reduced: qualifying reimbursements, exempt private-home gains, and income covered by a specific deduction, treaty rule, or tax-free threshold.

Based on our client scenario at TFX: an employee receives ISK 700,000 salary plus an employer-reported ISK 100,000 taxable benefit. The Icelandic employment-income base starts at ISK 800,000 before permitted pension or other deductions.

On the US side, nonwage items may flow through Form 1040 Schedule 1 or other schedules depending on the income type.

Personal tax credit and tax brackets

For 2025, Iceland’s personal tax credit was ISK 68,691 per month, or ISK 824,288 for the year. It reduces calculated income and municipal tax after the 3 wage brackets are applied. Employees with more than 1 employer require careful withholding instructions.

The 2025 personal credit can reduce payroll tax by up to ISK 68,691 each month, but it should not be duplicated across employers.

 

If pay from one employer already exceeds ISK 472,005 per month, the next employer may need to withhold at the higher bracket. Iceland Revenue and Customs places responsibility on the employee to give employers correct information.

Based on our client scenario at TFX: gross monthly pay is ISK 800,000, and the mandatory 4% pension premium is ISK 32,000. Taxable pay is ISK 768,000; calculated tax is about ISK 261,083, and the ISK 68,691 credit reduces it to about ISK 192,392.

US payroll withholding uses a different system. Our Form W-4 guide explains US withholding, while our guide to the minimum income to file US taxes covers federal return thresholds.

Capital gains for individuals

For 2025, Iceland generally taxed private capital gains at 22%. Gains on shares and taxable real-property sales fall within capital income, while a qualifying private-home gain can be tax-free after at least 2 years of ownership under Iceland’s residence rules.

The following 3 triggers are the most common for expats:

• Selling shares or fund interests at a gain.
• Selling Icelandic real estate when the private-residence exemption does not apply.
• Selling property used in a business, where business-income rules may replace private capital rules.

For private housing, Iceland Revenue and Customs states that a residence gain may be tax-free after 2 full years of ownership if the statutory conditions are met. Special rollover or deferral rules can apply when ownership was shorter.

Based on our client's scenario at TFX: shares are sold for ISK 5,000,000 with an ISK 4,000,000 cost basis. The gain is ISK 1,000,000; at 22%, Icelandic tax before any applicable allowance is ISK 220,000.

US citizens must also report taxable foreign gains under US rules. See our guide to capital gains for US expats.

Stock and other investment sales commonly require Form 8949 reporting on the US side, with basis converted to US dollars under applicable US tax rules.

Tax allowances, deductions, and credits

For 2025, Iceland allowed a 4% mandatory pension deduction from employment income and up to another 4% for qualifying private pension savings. The personal tax credit was ISK 824,288 annually, while other ordinary employee deductions from wage income were more limited.

The practical rule is that a deduction reduces the tax base, while the ISK 824,288 personal credit reduces calculated tax.

 

The following 4 records support the common claims above:

• Payslips showing pension premiums.
• Pension-fund annual statements.
• Employer travel or expense documentation.
• Tax card and withholding records showing personal-credit use.

US deductions are separate. Our guide to Schedule A itemized deductions for expats explains federal itemizing rules.

Keep both-country records in one file. Our tax documents checklist can help organize wage, investment, property, and foreign-tax evidence.

Double taxation relief for individuals

The US–Iceland tax treaty and US foreign tax credit rules can reduce tax charged twice on the same income. For 2025, Form 1116 is a common US mechanism, while treaty articles allocate taxing rights for items such as dividends, interest, royalties, and pensions.

The following 3-step decision flow is a practical starting point:

1. Identify which country has the primary or source-country taxing right for the income.
2. Check whether the treaty limits tax, exempts the item, or changes withholding.
3. Claim an available US foreign tax credit for qualifying Icelandic income tax that remains.

Our guide to how double taxation works for US expats explains the interaction between foreign tax, US tax, and relief methods.

The treaty does not create one universal exemption: each income type has its own article and the US savings clause can preserve US taxation of US citizens.

 

The treaty’s relief article requires the United States to allow a credit, subject to US law, for qualifying Icelandic income tax paid or accrued by US residents or citizens.

The following 3 proof items should be kept for a Form 1116 position:

• Icelandic tax return or assessment.
• Wage or investment statements showing Icelandic withholding.
• Proof of payment, refund, or final tax liability in Iceland.

See our guide to claiming the Foreign Tax Credit on Form 1116 for the US calculation and category rules.

Private housing benefits

For the 2026 Iceland assessment of 2025 interest, qualifying owner-occupiers can receive an interest subsidy capped at ISK 420,000 for a single person, ISK 525,000 for a single parent, or ISK 630,000 for a couple. Employer housing is a separate taxable-benefit issue.

The Icelandic “private housing benefit” on the older page is the interest subsidy for loans used to buy or build an owner-occupied home. It is income- and wealth-tested, and the underlying interest must meet statutory conditions.

The following 3 calculation limits apply to the 2026 assessment for 2025 interest:

• Eligible interest starts with the lowest of actual qualifying interest, 7% of qualifying year-end loan balances, or a statutory interest cap.
• Then 8.5% of the relevant income base is subtracted.
• Wealth reductions and the family-status maximum can further limit the subsidy.

Based on our client scenario at TFX: a single homeowner has ISK 600,000 qualifying interest, a 7% loan-balance amount above ISK 600,000, ISK 5,000,000 income, and wealth below the phaseout. ISK 600,000 minus 8.5% of income gives ISK 175,000 before other limits.

Employer-provided housing is different. Iceland generally includes benefits in kind in taxable employment income, using the applicable valuation rules.

Based on our client scenario at TFX: an employer reports ISK 250,000 a month as a taxable housing benefit. That ISK 250,000 is added to employment income for payroll withholding before the employee’s applicable deductions and credits.

The following 3 records support a housing-benefit position:

• Mortgage or lease terms and proof of payments.
• Employer calculations showing the value reported through payroll.
• Icelandic tax-return and assessment records supporting any interest subsidy.

For US expat rules, see the foreign housing exclusion. It is a separate Form 2555 benefit and does not mirror Iceland’s interest subsidy.

If you own rather than rent, our guide to buying foreign real estate covers US reporting issues that can arise.

The IRS also distinguishes taxable and nontaxable income under US rules, which can differ from Icelandic benefit valuation.

Child benefits

For the 2026 Iceland assessment, child benefits are income-related and generally require a dependent child plus Iceland domicile or more than 183 days of stay in a 12-month period. The general benefit continues through the year the child turns 18.

For the 2026 assessment, the headline annual amount is ISK 345,000 per child for couples and ISK 514,500 per child for single parents, before income reductions.

 

Foreign income affects the Iceland benefit calculation. A child normally must be registered with the supporter at year-end, and moving into or out of Iceland can prorate benefits by the period of residence.

The following 4 factors can reduce, prorate, or eliminate the benefit:

• Household income above the applicable threshold.
• Shorter residence caused by a move during the year.
• Family-status or support-person changes.
• Foreign child or family benefits that interact with Iceland’s EEA coordination rules.

US child rules are separate. For 2025, the maximum federal Child Tax Credit increased to $2,200 per eligible child, subject to current SSN and eligibility rules.

See the US Child Tax Credit guide and our guide to dependents and exemptions.

The IRS applies its own qualifying child rules for federal tax benefits. Icelandic child-benefit eligibility does not by itself establish US eligibility.

Social Security contributions

The United States and Iceland have had a Social Security totalization agreement in force since March 1, 2019. It can assign covered work to only 1 country and prevent double compulsory coverage. For 2025, Iceland’s general employer payroll tax was 6.35%.

The agreement can remove dual social-security contributions when its coverage rules apply, but Icelandic pension and payroll obligations still depend on the worker’s status and certificate.

 

Iceland’s official salary guidance states that a wage earner contributes at least 4% to a pension fund. Government employment guidance describes a 4% employee and 11.5% employer split under applicable arrangements.

A certificate of coverage is the evidence used to establish an exemption from the other country’s compulsory coverage. SSA can issue US certificates, while Iceland’s Social Insurance Administration issues Icelandic certificates.

See our guide to the certificate of coverage and A1 forms for the broader concept.

Our guide to totalization agreements for US expats explains how coverage coordination can affect cross-border work.

Based on our client scenario at TFX: an Iceland employee earns ISK 800,000 monthly. A 4% employee pension contribution is ISK 32,000. The employer’s 6.35% payroll tax on ISK 800,000 is ISK 50,800 before any special coverage rule or additional pension contribution.

Real estate tax

Icelandic real estate tax is municipal, so the rate depends on the property type and municipality. As a current 2026 example, Reykjavík charges 0.18% on residential assessed value and 1.60% on commercial property. Icelandic rental income can also remain reportable on a US return.

For property decisions, separate annual municipal property tax from income tax on rent and capital-gains tax on a sale.

 

Rental income from no more than 2 qualifying residential properties is treated as capital income, with 25% of the rental income tax-free and without any deductions under the stated conditions. This tax-free share applies for tax year 2025 as well as for tax year 2026.

Check Skatturinn's current-year page before filing, since this figure has moved before.

Based on our client's scenario at TFX: a landlord with ISK 3,000,000 of qualifying residential rent in 2025 would have ISK 2,250,000 taxable at 22%, for Icelandic tax of about ISK 495,000, before any other applicable allowance.

US citizens report foreign rental activity under US rules as well. See how foreign rental property is reported on a US tax return.

Investment income: withholding, dividends, interest, and royalties

For 2025, Iceland generally taxed resident individual capital income at 22%, including dividends and interest. The US–Iceland treaty can limit source-country tax on cross-border dividends, interest, and royalties, while US citizens still apply US reporting rules to the same income.

For an individual treaty claim, the key rates differ by income type: dividends can face a 15% treaty source cap, while interest is generally assigned to the residence country under Article 11.

 

Under Article 10, the treaty generally limits source-country dividend tax to 15% for individual investors. The 5% treaty dividend rate applies to qualifying corporate ownership, not the typical individual portfolio investor.

Article 11 generally gives the residence country the exclusive right to tax interest. Article 12 generally does the same for royalties, with a 5% source cap for certain trademarks, franchises, and film royalties.

For treaty-rate documentation, see our guide to foreign withholding forms.

US dividend reporting can differ from Icelandic statements. Our guides explain Form 1099-DIV and the taxation of foreign dividends.

Foreign interest should also be reviewed under US rules even if no US Form 1099 arrives. See our Form 1099-INT guide.

Based on our client scenario at TFX: a US citizen resident in Iceland receives ISK 500,000 of Icelandic dividends. At a 22% resident capital rate, Icelandic tax is ISK 110,000 before any specific allowance; the US return then tests FTC relief.

The relevant US credit rules are on the IRS Foreign Tax Credit page. Treaty reductions and FTC calculations should not be double-counted.

Iceland corporate taxation: brief overview

For 2025 income assessed in 2026, Iceland’s corporate income tax rate was 20% for limited-liability companies and 37.6% for specified other taxable legal entities. This section is only a business-owner overview; US owners can also face Form 5471, CFC, or other international reporting.

The following 4 setup items matter when operating a business in Iceland:

• Register the business or branch in the appropriate Icelandic register.
• Set up payroll withholding, pension payments, and employer charges when staff are hired.
• Keep Icelandic accounting and tax records.
• Register for VAT if taxable sales exceed the applicable threshold.

Entity choice affects both countries. See our guide to business structures for US expats before treating an Icelandic entity as equivalent to a US entity.

A foreign company can create separate US information-return duties for its US owners. Our foreign company tax reporting guide covers the major US forms.

US shareholders should also review the controlled foreign corporation rules when ownership thresholds or control tests may be met.

Iceland VAT (Value Added Tax)

The VAT system in Iceland uses a 24% standard rate and an 11% reduced rate. A business selling taxable goods or services is generally exempt from registration while taxable sales remain at ISK 2,000,000 or less in each 12-month period from the start of activity.

The registration decision starts with the ISK 2,000,000 rolling 12-month taxable-sales threshold, then the 24% or 11% rate depends on what is sold.

 

The 11% reduced rate applies to specified categories such as food, accommodation, books, and certain passenger transport. Exempt activities include categories such as health care, education, insurance, and financial services.

The following 3 VAT classifications should be checked before invoicing:

• Standard-rated taxable sales.
• Reduced-rated taxable sales.
• Exempt or zero-rated transactions under Icelandic VAT rules.

Based on our client scenario at TFX: a standard-rated service costs ISK 100,000 before VAT. At 24%, VAT is ISK 24,000, and the invoice total is ISK 124,000.

US owners should also confirm how the Icelandic entity is classified for federal tax. See our guide to the Form 8832 entity classification election.

Catching up on late US filings from Iceland

Americans living in Iceland who have not filed prior-year US returns may be able to use the Streamlined IRS compliance program to come into compliance. The program is available for non-willful situations and covers the full catch-up package the IRS requires from filers abroad.

A typical submission through the program includes:

• Three years of federal income tax returns covering Iceland wages, investment income, and other worldwide income
• Six years of FBARs for Icelandic bank and brokerage accounts that exceeded $10,000 in aggregate at any point in the year
• Form 8938 disclosures where foreign financial assets crossed the applicable threshold
• A non-willfulness certification explaining the circumstances of the filing gap

The foreign offshore track carries no miscellaneous offshore penalty for qualifying filers.

Iceland-based Americans with missed returns may qualify for the Streamlined Filing Procedure.
