Renouncing does not end your U.S. tax obligations. If you renounce your U.S. citizenship, you may still have to pay U.S. taxes in three ways: a one-time “exit tax” on unrealized gains if you cross certain wealth or income thresholds, ongoing income tax on anything you earn from U.S. sources for the rest of your life, and estate or gift tax exposure that can reach your U.S. heirs long after you leave.
The Exit Tax on the Way Out
The IRS treats renunciation as a taxable event for a narrow group called “covered expatriates.” You become one by tripping any single one of three tests:
- Your worldwide net worth is $2 million or more on your expatriation date. Real estate, investments, and retirement accounts all count, minus debts. Your spouse’s assets do not.1Internal Revenue Service. Expatriation Tax
- Your average annual net federal income tax over the five years before expatriation exceeds $211,000 for someone renouncing in 2026. That’s tax paid, not income.2Internal Revenue Service. Revenue Procedure 2025-32
- You cannot certify on Form 8854 that you’ve met all federal tax obligations for the prior five years. Fail this test and you’re a covered expatriate automatically, no matter how modest your finances.1Internal Revenue Service. Expatriation Tax
If you don’t meet any of the three, the exit tax doesn’t apply. If you do, the IRS calculates your tax as though you sold everything you own the day before your expatriation date. This is called mark-to-market. You take the difference between what you paid for each asset and its current fair market value, add up the unrealized gain, and report it as if you had cashed out.1Internal Revenue Service. Expatriation Tax
The first $910,000 of combined gain is excluded for anyone expatriating in 2026.2Internal Revenue Service. Revenue Procedure 2025-32 Gain above that is taxed at the applicable capital gains rate. You haven’t received any cash, but the tax bill is real.
If you became both a U.S. citizen and a citizen of another country at birth, still hold that other citizenship, are taxed as a resident there, and have not been a U.S. resident for more than 10 of the 15 years ending with your expatriation year, you can escape the net worth and average tax liability tests.3Office of the Law Revision Counsel. 26 U.S. Code 877A – Tax Responsibilities of Expatriation The certification test still applies.
Retirement Accounts Are Treated Differently
Mark-to-market doesn’t hit every asset the same way. For eligible deferred compensation plans such as certain employer pensions, the plan administrator withholds 30% on any distribution made to a covered expatriate. For traditional IRAs and 529 education savings plans, the IRS treats the entire balance as distributed the day before expatriation, making the full amount taxable in your final year as a citizen.1Internal Revenue Service. Expatriation Tax That deemed distribution can push you into a much higher bracket.
Deferring Payment
If you can’t pay the exit tax upfront, you can elect to defer it on a property-by-property basis. The tax on each asset comes due when you actually sell it, and interest accrues the whole time. This is financing, not a discount.4Internal Revenue Service. Instructions for Form 8854 (2025)
To qualify, you must post adequate security such as a bond or letter of credit, waive any treaty rights that would block IRS collection, and appoint a U.S.-based agent to receive IRS communications. The election is irrevocable, and you must keep filing Form 8854 every year until the deferred tax and interest are fully paid.4Internal Revenue Service. Instructions for Form 8854 (2025)
Getting Compliant Before You Renounce
Before the IRS clears you to leave the system, you must certify under penalty of perjury that you have complied with all federal tax obligations for the five tax years immediately before your expatriation date. That covers income tax returns, employment tax returns, gift tax returns, information returns, and foreign account reports like the FBAR. All taxes, penalties, and interest for those years must be paid.4Internal Revenue Service. Instructions for Form 8854 (2025)
Fail the certification and you’re a covered expatriate automatically, exit tax and all, regardless of your net worth or income. Anyone behind on filings needs to catch up before renouncing, not after.
If you’ve been living abroad and didn’t realize you needed to file, the IRS Streamlined Foreign Offshore Procedures are designed for this situation. To qualify, your failure to file must have been non-willful, meaning negligence, mistake, or a good-faith misunderstanding rather than deliberate avoidance. You also need to have been physically outside the United States for at least 330 full days in at least one of the three most recent tax years.5Internal Revenue Service. U.S. Taxpayers Residing Outside the United States The program lets you file three years of back returns and six years of delinquent FBARs without the standard late-filing penalties.
Form 8854, the Initial and Annual Expatriation Statement, is the central document. You attach it to your income tax return for the year that includes your expatriation date. It requires a balance sheet of your worldwide assets and a summary of income and tax liability for the five-year look-back. If you aren’t otherwise required to file, you still have to send Form 8854 by the date a return would have been due.4Internal Revenue Service. Instructions for Form 8854 (2025) You also file a dual-status return for the year you renounce: Form 1040 for the citizen portion of the year, Form 1040-NR for the nonresident alien portion.
U.S. Taxes After You Renounce
Once you’re out, you’re treated as a nonresident alien. The U.S. taxes you only on income sourced inside the United States, but that category catches more than people expect: rent from U.S. real estate, dividends from U.S. stocks, wages for any work you perform inside the country. U.S.-source income for nonresident aliens is generally subject to a flat 30% withholding, though a tax treaty between the U.S. and your country of residence may reduce that rate.6Internal Revenue Service. Nonresident Aliens – Sourcing of Income If you have ongoing U.S.-source income, you keep filing Form 1040-NR each year.
Don’t Trigger the Substantial Presence Test
Spend too much time in the United States as a foreign national and the IRS can pull you back in as a tax resident. The substantial presence test counts all days present in the current year, plus one-third of days from the prior year, plus one-sixth of days two years back. Hit 183 on that formula and you owe U.S. tax on your worldwide income again.7Internal Revenue Service. Substantial Presence Test A closer connection exception exists if you spend fewer than 183 actual days in the U.S. during the year and maintain a tax home in a foreign country, but leaning on exceptions is riskier than limiting your visits.
Estate Tax Stays With Your U.S. Property
If you die owning U.S.-situated property after renouncing, your estate faces federal estate tax with a much smaller exemption than a citizen would get. The filing threshold for a nonresident alien’s estate is just $60,000 in U.S.-situated assets, and that number is not adjusted for inflation.8Internal Revenue Service. Estate Tax for Nonresidents Not Citizens of the United States U.S.-situated assets include American real estate, shares of U.S. companies, and tangible property in the country. A treaty may raise the effective exemption, but many former citizens are caught off guard by how low the baseline is.
Gifts and Bequests to U.S. Heirs
If you leave the U.S. as a covered expatriate, any gifts or bequests you later make to U.S. citizens or residents are subject to a special tax under IRC 2801. The recipient pays it, not you, at the highest federal estate tax rate, currently 40%.9Office of the Law Revision Counsel. 26 USC 2801 – Imposition of Tax The tax applies only to the extent that covered gifts and bequests received in a calendar year exceed the annual gift tax exclusion, which is $19,000 for 2026.10Internal Revenue Service. Frequently Asked Questions on Gift Taxes
U.S. heirs report these transfers on Form 708. If the gift or bequest already triggered a foreign gift or estate tax, the IRC 2801 tax is reduced by the amount paid abroad. Covered expatriate status follows you into your estate plan and reaches the people you leave money to.
Social Security After Renunciation
If you earned enough credits to qualify for Social Security before renouncing, you don’t automatically lose the benefits, but collecting them from outside the U.S. as a noncitizen is harder. The Social Security Administration generally stops payments after you’ve been outside the country for six consecutive calendar months. To restart them, you would need to return and remain physically present for at least 30 consecutive days.11Social Security Administration. Social Security Payments Outside the United States
The main workaround is a totalization agreement. The United States has Social Security agreements with about 30 countries, including Canada, the United Kingdom, Germany, Japan, Australia, and most of Western Europe.12Social Security Administration. Country List 3 Live in one of those and the six-month suspension generally doesn’t apply. Live somewhere without an agreement and you plan around the payment restrictions or lose the benefit.
One Boundary Worth Knowing
Federal law contains a provision, sometimes called the Reed Amendment, that makes former citizens inadmissible to the United States if the Attorney General determines they renounced to avoid taxes.13Department of Homeland Security. Inadmissibility of Tax-Based Citizenship Renunciants In practice, the provision has been enforced only twice since 2002. It remains on the books, and the safer assumption is that the government retains discretion to deny entry even if it rarely uses it.
