The exit tax in the USA imposes significant tax liabilities on certain U.S. citizens or long-term residents who renounce citizenship or green card status. Known formally as the expatriation tax under IRC Section 877A, it treats expatriates as selling their worldwide assets on the day before departure.
The exit tax USA, enacted via the HEART Act of 2008, prevents wealthy individuals from avoiding U.S. taxes by leaving the system. It applies a "mark-to-market" regime, deeming a sale of all assets at fair market value (FMV) the day before expatriation, taxing unrealized gains.
This mechanism ensures the U.S. captures deferred taxes on appreciated property before the individual shifts to a potentially lower-tax jurisdiction. Only "covered expatriates" face this tax, making it a targeted measure rather than a blanket penalty.
Covered expatriates trigger the exit tax USA if they meet any of three tests on their expatriation date. First, the net worth test: worldwide net worth of $2 million or more—this fixed threshold isn't inflation-adjusted.
Second, the tax liability test: average annual net U.S. income tax over the prior five years exceeds $211,000 for 2026 (inflation-adjusted from $201,000 in 2024).
Third, the compliance test: failure to certify full U.S. tax compliance for the five preceding years via Form 8854. Exceptions apply for dual citizens at birth, minors under 18.5, or those not U.S. tax residents for 10 of 15 prior years.
Long-term residents—green card holders for 8 of 15 prior years—face the same rules as citizens relinquishing nationality.
Calculation begins with a deemed sale of worldwide assets at FMV the day before expatriation. Gains above a 2026 exclusion of $910,000 (up from $866,000 in 2024) incur capital gains tax at regular rates (up to 20% long-term, plus 3.8% net investment income tax).
Example: A covered expatriate with $1.5M net gain post-exclusion pays ~$300,000+ in tax, plus handling deferred items separately. Total liability aggregates across categories.
Form 8854, the Initial and Annual Expatriation Statement, must attach to your final U.S. tax return (Form 1040 or 1040-NR) by its due date, including extensions. It certifies five-year compliance, details net worth/assets, and computes exit tax if applicable.
Failure auto-classifies you as covered, triggers penalties ($10,000+), and sustains U.S. worldwide taxation. Non-filers risk criminal liability.
Not all expatriates pay; only covered ones do. Dual nationals or "accidental Americans" (birthright citizens never U.S.-resident) often qualify for relief if tax-resident elsewhere.
Pre-expatriation gifts reduce net worth below $2M, but watch gift taxes. Treaty claims via Form 8833 may exclude years from long-term resident count.
Minors and certain pre-18.5 renunciations get full exemptions. No tax if total net gain stays under the exclusion.
Strategic timing expatriates before asset appreciation or high-income years. Realize losses pre-exit to offset deemed gains.
Professional appraisals and cross-border advice optimize valuations/treaties. Pre-exit compliance cleans five-year history.

Upfront tax cost
For 2026, exclusion rises to $910,000; liability threshold to $211,000. No major HEART Act changes, but inflation tweaks persist.
Proposed bills (e.g., LaHood's) eye estate tax exemption alignment (~$14M net worth safe harbor), but unpassed as of February 2026. Ongoing IRS scrutiny on compliance certifications rises.
Expatriates retain U.S.-source income taxation (e.g., rentals, dividends via withholding). FIRPTA hits U.S. realty sales; gifts/estates to U.S. persons may tax.
Annual Form 8854 required for deferrals/tax installment agreements. Foreign trusts/accounts trigger ongoing FATCA/FBAR if U.S. ties remain.
Many believe it's avoidable by secrecy—false; IRS cross-checks State Department renunciations. Green card abandonment before 8/15 years dodges it entirely.
It's not a wealth tax but gain-based; low-basis assets hurt most. No double-tax relief guaranteed post-exit.
