Renouncing U.S. Citizenship — The Tax Checklist
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Renouncing U.S. citizenship — or surrendering a long-held green card — ends worldwide U.S. taxation going forward, but only after a defined tax exit: certifying five years of compliance, filing Form 8854, and for people above certain thresholds, paying an exit tax computed as if every asset were sold the day before expatriation. The immigration act and the tax act are separate; skipping the second doesn't make it go away.

What has to be done before the appointment?
The tax position should be clean first. Form 8854 requires you to certify under penalty of perjury that you complied with all U.S. tax obligations for the five years before the year of expatriation — returns filed, tax paid, FBARs and information returns in. If you can't certify, you are automatically a "covered expatriate" and subject to the exit tax regardless of wealth. Expats who are behind typically use the Streamlined procedures to get the five years in order before renouncing.
Who is a covered expatriate?
You are covered — and face the exit tax — if any one of three tests is met:
- Net worth of $2 million or more on the expatriation date.
- Average annual U.S. tax liability over the prior five years above an inflation-adjusted threshold (a threshold on the tax itself, in the low six figures — not on income).
- Failure to certify five years of compliance.
Two exceptions: people who were dual citizens from birth, still hold the other citizenship, and have been U.S. residents for no more than a limited number of years; and people who renounce before age 18½ with limited U.S. residence. Both still must file Form 8854 to claim the exception.
How does the exit tax work?
Covered expatriates are treated as having sold all their worldwide property at fair market value on the day before expatriating. The net gain above an inflation-adjusted exclusion is taxed in the year of expatriation. Certain assets are handled differently: retirement accounts and deferred compensation are either taxed as a lump sum or subjected to withholding on future distributions, and interests in trusts have their own rules. The tax can be deferred with security posted, but interest runs.
What is Form 8854?
The expatriation statement, filed with the final dual-status return for the year you expatriate. It lists your assets and liabilities, certifies compliance, and determines covered status. Failing to file it has a fixed penalty and, more importantly, leaves you treated as a covered expatriate — and in some readings, still a U.S. taxpayer — until it's filed.
What stays taxable after I renounce?
U.S.-source income: rental income from U.S. property, dividends and interest from U.S. payers (often subject to flat withholding as a non-resident), and gains on U.S. real estate. Social Security benefits remain payable in most countries, with non-resident withholding. If you were a covered expatriate, gifts and bequests you later make to U.S. persons can be taxed to the recipient under a special rule.
What is the process in order?
- Confirm five years of U.S. compliance; fix gaps first.
- Model the covered-expatriate tests and the exit tax exposure; consider timing and gifting within the rules before the date.
- Book and attend the consular appointment; take the oath; receive the certificate of loss of nationality.
- File the final dual-status return and Form 8854 by the following year's deadline.
- Update U.S. payers and banks on your non-resident status.
Frequently asked questions
Does renouncing erase past unfiled years?
No. The five-year certification requires them to be filed, and the IRS can still pursue earlier years.
I have a green card, not citizenship. Do these rules apply?
Yes, if you held it in at least eight of the last fifteen years. Shorter-term holders simply surrender the card without the exit regime.
Can I renounce to avoid the exit tax before my net worth grows?
Timing is legitimate; the tests are measured on the expatriation date. Gifting to reduce net worth is subject to gift tax rules and scrutiny.
Will I lose Social Security?
Generally no — benefits earned are payable to non-citizens living abroad in most countries, with withholding.
