Explanations & Disclaimers
This calculator is for educational and tax-estimation purposes only, such as using in planning for withholding via IRS forms 673 or W-4. It does not constitute tax, legal, or financial advice. It is not a substitute for consulting IRS publications, using full-featured tax software (for example, TurboTax), or obtaining advice from a qualified tax professional. U.S. international tax rules are complex and subject to change. However, this tool can be very helpful in checking against anything you received from an accountant or tax software. The target audience is an individual who may use the Foreign Earned Income Exclusion, such as a contractor for a US company that is based in Japan and meets FEIE criteria.
Why did I include some tax situations and not others? I aimed to create a simple interface that still addresses the most significant issues expats face when using the FEIE. I’ve seen tens of thousands of dollars in IRS overpayments and costly decisions driven by misunderstandings of individual tax situations. My hope is that this tool helps you build the knowledge needed to make better, more informed decisions well before tax preparation time.
In December 2025, the IRS published tax brackets, standard deductions, and various limits for tax years 2025 and 2026. However, most individual forms and instructions were not released yet. When a form does not exist, this estimator follows previous tax year procedures, incorporating any known tax law changes (OBBB). Note that because of variations in rounding styles and differences across IRS tax forms, tax tables, and worksheets, you can expect results from this estimator to vary by approximately by a few tens of dollars compared to other methods (for example, TurboTax). However, it's going to get the big things accurate and its purpose is education.
What is the Foreign Earned Income Exclusion (FEIE)?
The Foreign Earned Income Exclusion (FEIE) allows U.S. citizens and resident aliens living and working abroad to exclude a portion of their foreign-earned income from U.S. federal income tax. The governing guidance is IRS Publication 54 and IRS Form 2555, which is used to calculate the exclusion. IRS Publication 54 includes an example of a U.S. contractor working in Japan for a U.S. company. The FEIE limit for 2025 is $130,000, but may be affected by other employer benefits such as housing.
Eligibility: You must satisfy either the physical presence test or the bona fide residence test.
Physical presence test: Generally satisfied by spending 330 full days outside the United States during a 12-month period that overlaps the tax year. If the 12-month period does not equal the tax year, the amount of exclusion is reduced from the maximum amount.
Bona fide residence test: Generally requires establishing residence in a foreign country, intending to reside there for an extended period, and not maintaining a U.S. home; additional factors may apply.
Foreign Earned Income (Taxpayer or Spouse) includes:
Portion of W-2 wages earned while working outside the United States
Portion of foreign wages earned while working outside the United States
Portion of self-employment income (profits) earned while working outside the United States
US Earned Income (Taxpayer or Spouse) includes:
Portion of W-2 wages earned while working inside the United States
Portion of self-employment income (profits) earned while working inside the United States
Any W-2 income received directly from the US government, such as miliary salary or government service civilian salary is considered US-earned income for the purposes of the FEIE, even if it was earned while outside the US.
Interest includes:
Interest from items such as savings accounts and bonds, ususally reported on a 1099-INT.
Rental Property Profit or (Loss) includes:
Profits from rental real estate, royalties, partnerships, S corporations, estates, trusts, and residual interests. This is normally filed to the IRS on a Form 1040 Schedule E.
You must include depreciation as an expense, which often results in a loss on paper.
You cannot use passive losses to offset any active income or portfolio income, but you may use the to offset passive income in the current year or the future using IRS Form 8582.
Traditional IRA/401K/TSP disbursements or roth conversions:
Distributions from traditional IRA/401(k)/TSP accounts
Conversions from traditional IRA/401(k)/TSP to Roth accounts
Pensions & Annuities include:
Taxable pensions such as a US military pension.
Taxable annuities.
This does not include non-taxable Veterans Administration benefits.
Short-Term Capital Gains include
Gains from the sale of assets held for less than one year. These are generally taxed at ordinary tax rates instead of favorable tax rates reserved for long-term capital gains.
Enter capital losses as a negative value. Up to $3,000 per year of capital losses can be used to offset other sources of income, such as wages.
Unqualified Dividends include
Unqualified dividends are dividends that do not meet IRS requirements to be treated as qualified—typically due to not meeting the required holding period or because the dividends come from certain types of companies or foreign corporations.
Investment statements usually report **total ordinary dividends** and **qualified dividends**. In this case, the amount of **unqualified dividends** is simply the difference: ordinary dividends minus qualified dividends.
Long-Term Capital Gains include
Long-term capital gains are profits from selling investments—such as stocks, mutual funds, or real estate—that you held for more than one year. These gains are taxed at special, generally lower tax rates compared to short-term capital gains.
Brokerage statements typically report both short-term and long-term capital gains separately. The long-term portion reflects your gains on assets held longer than one year and qualifies for the favorable long-term capital gains tax rates.
Enter capital losses as a negative value. Up to $3,000 per year of capital losses can be used to offset other sources of income, such as wages.
Qualified Dividends include
Qualified dividends are dividends that meet specific IRS criteria to be taxed at the lower long-term capital gains rates. To qualify, the dividend must come from an eligible U.S. or qualified foreign corporation, and you must meet the required holding period for the stock.
On most investment statements, qualified dividends are listed separately from total ordinary dividends. The qualified amount is the portion of your ordinary dividends that receives the favorable tax rate.
Additonal Topics That Mase Arise
Child Tax Credit (CTC)
The Child Tax Credit reduces your U.S. income tax based on the number of qualifying children under age 17 with the appropriate passport, and the credit amount phases out at higher income levels.
For expats using the Foreign Earned Income Exclusion, the credit is nonrefundable, meaning that you only see the value if it can offset regular taxes.
Importantly, the Child Tax Credit cannot be used to offset either the Net Investment Income Tax (NIIT) or the Self-Employment Tax, which are not regular taxes.
Net Investment Income Tax (NIIT)
The NIIT is a 3.8% surtax applied to investment income—such as dividends, interest, capital gains, and passive rental income—once your modified adjusted gross income exceeds specific thresholds, $250,000 for married filing jointly.
This tax applies separately from regular income tax and is not affected by the Foreign Earned Income Exclusion, meaning excluded wages do not reduce the income used to determine NIIT.
Self-Employment Tax (SE Tax)
Self-employment tax covers the Social Security and Medicare taxes on net earnings from self-employment and applies even if those earnings are excluded from income tax using the FEIE.
It is calculated on net business profit reported on Schedule C and then carried to Schedule SE, where the combined 15.3% rate is applied before any available adjustments.
