If you hold a U.S. green card, tax filing for green card holders works the same way it does for citizens: you file a Form 1040 each year and report your worldwide income, no matter where you live or where the money came from. For 2026, federal rates run from 10% to 37%, and you generally must file if your gross income tops the standard deduction for your filing status ($16,100 single, $32,200 married filing jointly).1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 What sets your return apart from a citizen’s is not the form itself but the extra reporting: foreign accounts, foreign income, and the tools that keep the same dollar from being taxed twice.
Why Your Status Alone Triggers U.S. Tax
The IRS applies the “green card test” under Internal Revenue Code Section 7701(b). If you were a lawful permanent resident at any point during the calendar year, you are a U.S. tax resident for that entire year.2eCFR. 26 CFR 301.7701(b)-1 – Resident Alien The number of days you spent inside the United States is irrelevant. Wages from a foreign employer, rent from property abroad, interest on overseas accounts, and gains on foreign asset sales all belong on your U.S. return.3Internal Revenue Service. U.S. Residents
This continues until the IRS receives notice that your card has been revoked, formally abandoned, or administratively closed. Living abroad, keeping a home overseas, or spending most of the year outside the country does not switch off the obligation.
Your First Year as a Green Card Holder
The year your green card is issued usually splits in two for tax purposes. Before the card, you were a nonresident alien taxed only on U.S.-source income. After, you became a resident alien taxed on income from anywhere. The IRS calls this a dual-status year.
If you are a resident on December 31, you file Form 1040 with “Dual-Status Return” written across the top and attach a Form 1040-NR marked “Dual-Status Statement” for the nonresident portion.4Internal Revenue Service. Taxation of Dual-Status Individuals The nonresident portion covers only U.S.-connected income; the resident portion covers global income. Dual-status filers cannot use the standard deduction and cannot file jointly with a spouse, which often pushes the tax bill higher for that year. Some new residents may make a first-year choice to be treated as a resident for the whole year, which restores joint filing and the standard deduction but pulls all worldwide income from January 1 into the return.
Deadlines and How to File
The regular filing deadline is April 15, the same date that applies to citizens.5Internal Revenue Service. When to File Form 4868 buys an automatic six-month extension to October 15, but only for filing. Any balance owed still accrues interest and penalties from April 15.
Green card holders who are living and working abroad on April 15 get an automatic two-month extension to June 15 with no advance paperwork; you attach a short statement to the return explaining you were outside the country on the due date.6Internal Revenue Service. Automatic 2-Month Extension of Time to File Interest on unpaid tax still runs from April 15 even with this extension.
Returns go on Form 1040, the same form citizens use. E-filing usually confirms within 24 hours and delivers refunds in about three weeks; paper returns take six weeks or more.7Internal Revenue Service. Refunds Balances can be paid through IRS Direct Pay or the Electronic Federal Tax Payment System.
Reporting Foreign Accounts and Assets
Two separate foreign-reporting rules apply to most green card holders with overseas money, and they trip up even careful filers. They serve different agencies, cover overlapping but different assets, and carry their own penalties.
FBAR (FinCEN Form 114)
If the combined value of your foreign financial accounts crosses $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts. It goes to the Financial Crimes Enforcement Network through the BSA E-Filing system, not to the IRS with your return.8Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The threshold is cumulative: two accounts that together exceed $10,000 both need to be listed.9Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements The FBAR is due April 15, with an automatic extension to October 15 requiring no request.
Form 8938 (FATCA)
Form 8938 is filed with your tax return when your foreign financial assets exceed higher thresholds. For green card holders living in the U.S., that is $50,000 on the last day of the year or $75,000 at any point (both double for joint filers). For those living abroad, the thresholds rise to $200,000 on the last day or $300,000 at any point, and $400,000/$600,000 for joint filers.10Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Form 8938 also reaches beyond bank accounts to foreign stock, securities, and interests in foreign entities.
The penalty for missing Form 8938 is $10,000, rising to $50,000 if you still have not filed after IRS notification. Any tax underpayment tied to undisclosed foreign assets triggers an added 40% penalty on the understatement, and criminal charges are possible in extreme cases.11Internal Revenue Service. FATCA Information for Individuals Many green card holders file both forms because the coverage overlaps but is not identical.
Converting Foreign Amounts
All figures on your return must be in U.S. dollars. Use the exchange rate in effect when you received, paid, or accrued each item. Acceptable sources include the Treasury Department, the Federal Reserve, and commercial services such as xe.com and oanda.com.12Internal Revenue Service. Foreign Currency and Currency Exchange Rates Keep records showing which rates you used. Inconsistent conversions are a common audit trigger.
Keeping the Same Income From Being Taxed Twice
If another country already taxes some of your income, the code offers two main ways to avoid paying full U.S. tax on top of that, plus a third route through treaties.
Foreign Tax Credit
Foreign income taxes you paid to another country can be claimed as a dollar-for-dollar credit on Form 1116.13Internal Revenue Service. Foreign Tax Credit The credit is capped at the U.S. tax attributable to your foreign income, so it will not eliminate tax on your domestic earnings. Small amounts (generally under $300, or $600 for joint filers) can be claimed directly on Form 1040 without filing Form 1116. Taking a deduction for the foreign tax is an option, but the credit almost always produces a better result.
Foreign Earned Income Exclusion
Green card holders living and working abroad may exclude up to $132,900 of foreign earned income for 2026, plus a housing amount of up to $39,870, using Form 2555.14Internal Revenue Service. Figuring the Foreign Earned Income Exclusion Your tax home must be in a foreign country, and you must meet one of two tests. The physical presence test requires 330 full days in a foreign country during a 12-month period. The bona fide residence test requires an uninterrupted period of foreign residence spanning a full tax year, but for resident aliens it is available only if you are a citizen or national of a country that has an income tax treaty with the United States.15Internal Revenue Service. Foreign Earned Income Exclusion
The exclusion covers earned income only. Investment returns, pensions, and rental income do not qualify. You cannot use the exclusion and the foreign tax credit on the same dollars, but you can pair them across different income types.
Treaty Positions
Income tax treaties can reduce withholding, exempt certain income, or resolve residency conflicts. If you take a treaty position that overrides the normal code result, you must disclose it on Form 8833 with your return.16Internal Revenue Service. About Form 8833, Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b) Skipping the form can cost $1,000 per undisclosed position. Treaty benefits often matter most for pensions, royalties, and dividends from a home country.
What Late or Missing Returns Cost
The failure-to-file penalty is 5% of unpaid tax per month or partial month, up to 25%. A separate failure-to-pay penalty of 0.5% per month applies to unpaid balances after the deadline. They run at the same time, but the filing penalty is reduced by the payment penalty so they do not fully stack.17Internal Revenue Service. Failure to File Penalty
Foreign information returns carry their own charges on top. A missed Form 8938 is $10,000, rising to $50,000 after IRS notice, and applies even if no tax is owed.18Internal Revenue Service. International Information Reporting Penalties Multiple missed years can also create problems at a naturalization interview, since USCIS reviews tax compliance under the good moral character requirement.
The IRS generally has three years from filing to audit. That window stretches to six years if you omit more than 25% of gross income, and it never closes if you do not file or if fraud is suspected.19Internal Revenue Service. Topic No. 305, Recordkeeping Keep supporting records at least three years, longer if you have foreign assets or complex income.
If You Ever Give Up the Card
Surrendering a green card does not end your tax obligations on the date you hand it in. You file Form I-407 with USCIS, and the agency notifies the IRS.20U.S. Citizenship and Immigration Services. I-407, Record of Abandonment of Lawful Permanent Resident Status You then file Form 8854 for the year of expatriation and a final Form 1040 for the resident portion of that year.
The exit tax applies if you are a “long-term resident,” defined as someone who held a green card in at least 8 of the previous 15 tax years, and you meet certain net worth or tax liability thresholds that make you a “covered expatriate.”21Office of the Law Revision Counsel. 26 U.S. Code 877 – Expatriation to Avoid Tax Covered expatriates are treated as if they sold all their assets at fair market value the day before expatriation, with gain above an exclusion amount taxed as income.22Internal Revenue Service. Expatriation Tax Held the card for fewer than 8 of the last 15 years and the exit tax generally does not apply, though the final return still does. The 8-year threshold is one of the more consequential lines in the code for a permanent resident considering departure.
