Top 10 US Expat Tax Deductions To Know in 2026

1. Foreign Earned Income Exclusion (FEIE)

The Foreign Earned Income Exclusion (FEIE) is one of the most valuable US expat tax deductions. It allows eligible US citizens and resident aliens living abroad to exclude up to $130,000 of foreign-earned income in 2026 from US federal income taxes.

To qualify, you must meet either the Bona Fide Residence Test, meaning you reside in a foreign country for a full tax year, or the Physical Presence Test, requiring at least 330 full days outside the United States in any 12-month period.

FEIE is especially beneficial for self-employed expats, though Social Security and Medicare taxes still apply. It can also be combined with the Foreign Housing Exclusion, allowing additional deductions for reasonable housing expenses abroad. Maintaining accurate records, including proof of residence and foreign income, is essential to ensure compliance and maximize the benefits of FEIE.

2. Foreign Housing Exclusion or Deduction

The Foreign Housing Exclusion or Deduction allows expats to deduct certain housing costs incurred while living abroad. Eligible expenses typically include rent, utilities, property insurance, and sometimes minor repairs.

• Employed expats: Use the exclusion to lower taxable income.
• Self-employed expats: Claim it as a deduction on Schedule C.

The deduction limit varies depending on your foreign location, as the IRS provides a maximum housing amount for each city and country. Combining this deduction with FEIE can substantially reduce your US taxable income.

Accurate documentation, such as rental agreements and utility bills, is crucial. Housing deductions not only reduce taxes but also make living abroad more financially manageable, particularly in countries with high housing costs.

3. Foreign Tax Credit (FTC)

The Foreign Tax Credit isn’t a deduction, but it directly reduces your US tax owed by offsetting taxes paid to a foreign government. It can be carried back one year or forward up to ten years if not fully used.

The FTC is especially valuable in countries where local income tax rates are higher than US rates, helping expats avoid double taxation. You can claim it for income, war profits, and excess profits taxes paid abroad.

Additionally, US expats may still be eligible for a refundable Child Tax Credit on their 2025 tax return, even if they owe little or no US tax. This means you could receive a refund for qualifying children while also taking advantage of the FTC.

4. Standard or Itemized Deductions

US expats can still claim either the standard deduction or itemized deductions, depending on which provides the greater tax benefit.

For 2026 (used on 2025 US tax returns), the standard deduction has increased to:

• $16,100 for single filers

• $32,200 for married filing jointly

Common itemized deductions include:

• Charitable contributions to qualified organizations
• Mortgage interest on US-based property
• State and local taxes (if applicable)

Many expats find the standard deduction simpler and more advantageous, particularly when overseas expenses are limited. Choosing the right deduction type requires careful consideration of personal circumstances, such as charitable contributions or US property ownership.

Combining standard or itemized deductions with FEIE, housing, or other credits can significantly lower US taxable income while maintaining compliance with IRS rules.

5. Retirement Contributions

Contributions to certain retirement accounts can reduce taxable income and are an important part of expat tax planning. Eligible accounts include:

• Traditional IRA
• 401(k)
• SEP IRA or Solo 401(k) for self-employed individuals

While Roth IRA contributions are not deductible, qualified withdrawals are tax-free. For self-employed expats, contributions to a Solo 401(k) or SEP IRA can provide both tax savings and retirement growth.

Careful tracking of contributions and adherence to IRS limits is essential, particularly when combining foreign earned income with retirement contributions. These deductions help reduce US taxes while preparing for long-term financial security abroad.

6. Self-Employment Deductions

Self-employed expats have access to a variety of US expat tax deductions to offset business income. Common deductions include:

• Office supplies, software, and equipment
• Marketing and advertising expenses
• Business travel and conferences
• Health insurance premiums
• Retirement plan contributions

Maintaining detailed records of all expenses is critical for maximizing deductions and avoiding IRS scrutiny. Business expenses must be ordinary and necessary to qualify. Combining these deductions with FEIE, housing, and foreign tax credits can substantially reduce overall US tax liability, making self-employment abroad more financially sustainable.

7. Education and Dependent Deductions

Expats with dependents can claim deductions and credits to reduce taxes. This includes:

• Child Tax Credit for qualifying children living abroad
• Dependent care credits for childcare or educational expenses

Residency rules and income limitations may apply, so careful planning is necessary. These deductions are particularly helpful for families living overseas, as they can reduce US tax liability while supporting dependents.

Accurate documentation, including proof of age, relationship, and foreign residency, is essential to claim these benefits.

8. Health Insurance Premiums

Health insurance premiums for self-employed or independently insured expats may be fully deductible.

• Covers premiums for yourself, your spouse, and dependents
• Deduction reduces taxable income and provides significant tax savings

For expats without employer-provided insurance, this deduction can be critical. Maintaining detailed records of payments and policy coverage ensures proper reporting and compliance. Combined with other deductions, health insurance premiums can meaningfully lower overall US tax liability while living abroad.

9. Travel and Moving Expenses (Limited)

Although most employee moving expense deductions were eliminated under the Tax Cuts and Jobs Act, self-employed expats may still deduct certain business-related travel and relocation expenses.

Eligible expenses include:

• Travel for client meetings or conferences
• Temporary relocation abroad

Receipts and documentation are essential. These deductions can reduce taxable income while making international business travel and relocation more affordable. When combined with other self-employment deductions, they provide additional opportunities to optimize US taxes.

10. Business Use of Home

Expats who operate a business from their foreign residence may qualify for the home office deduction.

• Deduct a portion of rent, utilities, and internet based on the percentage of space used exclusively for business
• Must be used regularly and exclusively for business purposes
• Works in combination with other self-employment deductions

Accurate measurement of home office space and expense tracking ensures compliance and maximizes deductions. This deduction is particularly valuable for freelancers and small business owners living abroad.
