Income, status and age
Income, filing status and age generally determine whether a return is required. Use the IRS rules for your tax year and circumstances.
An orientation to US federal taxes for citizens and resident aliens abroad: worldwide income, the filing check, the two main tax breaks, foreign account reports, currency and dates. Written for the 2025 federal return.
US citizens and resident aliens generally report worldwide income, including income earned abroad. Moving abroad alone does not end federal obligations.
The starting point is income from everywhere: the United States and the countries where you live, work or invest. Your address and the currency you are paid in do not turn foreign earnings into an automatic exemption.
Make an income list before choosing any tax break, and keep the statements behind each amount. This is a practical recommendation, not a tax rule.
Whether a return is required and the final tax owed are separate checks. Overseas tax benefits are available only when the relevant return is filed.
Income, filing status and age generally determine whether a return is required. Use the IRS rules for your tax year and circumstances.
Foreign earned income or foreign housing amounts count in gross income for the filing requirement, even if you expect to exclude them.
Self-employment, being claimed as someone else's dependent and other tax situations can change the filing check.
The foreign earned income exclusion concerns qualifying earnings from work abroad; the foreign tax credit concerns qualifying foreign taxes. Neither is a blanket promise of a tax-free return.
| Foreign earned income exclusion (FEIE) | Foreign tax credit (FTC) | |
|---|---|---|
| What it does | Can exclude qualifying foreign earned income up to an annual limit. | May reduce US tax liability when qualifying foreign tax was paid or accrued on income also subject to US tax. |
| What it needs | Foreign earned income, a foreign tax home, and an applicable residence or physical-presence test. Living abroad alone is not enough. | Qualifying foreign tax. Not every foreign charge qualifies. |
| How it is claimed | On the federal return. | Individuals generally use Form 1116. |
| Watch for | Pensions, including social security benefits, are not foreign earned income. The exclusion does not reduce self-employment tax. | No credit for taxes on income excluded through the FEIE or the foreign housing exclusion. |
Choosing a claim depends on your actual income, foreign taxes and circumstances. This overview does not select one for you.
Filing Form 8938 does not replace an FBAR. Either, both or neither can be required.
| FBAR (FinCEN Form 114) | Form 8938 | |
|---|---|---|
| Who generally files | A US person with a financial interest in or signature authority over foreign financial accounts whose combined value exceeds $10,000 at any time in the calendar year. Check the instructions for exceptions. | Check your specified foreign financial assets against the applicable threshold. Thresholds depend on filing status and whether you qualify as living abroad. |
| What it covers | Foreign financial accounts. | Specified foreign financial assets, which are not identical to FBAR accounts. |
| Where it goes | Filed separately to FinCEN through its BSA E-Filing system. | Attached to the federal income tax return when required. |
| Values | Use the FBAR's own valuation and conversion instructions. | Use Form 8938's own valuation and conversion instructions. |

US return amounts are reported in US dollars. For a taxpayer whose functional currency is the dollar, the IRS generally points to the exchange rate when an item is received, paid or accrued. The conversion must match the item and the applicable rules.
