How to Legally Reduce or Avoid the US Exit Tax

The exit tax only reaches covered expatriates, so most planning aims to avoid covered status: keep net worth below $2,000,000, maintain five years of clean filings so you can certify on Form 8854, and time your departure. Below, settled IRS rules are marked clearly and separated from planning opinions you should confirm with a professional.
Start by understanding what you are avoiding
RULE The exit tax applies only to covered expatriates, and only to unrealized gain above the 2026 exclusion of $910,000. If you are not covered, there is no exit tax to avoid, only the $450 fee. So the first move is always to check your status in the calculator.
Strategy 1: Stay below the net-worth threshold
PLANNING If your wealth is near the line, transferring assets before expatriation (for example to a spouse) can bring your individual net worth below $2,000,000. RULE Gift-tax rules apply to those transfers, and gifts to a non-US-citizen spouse have their own annual limit. The transfers must be real and completed before you expatriate, which is why timing and documentation matter.
Strategy 2: Keep five clean years and certify
RULE Failure to certify five years of compliance makes you covered automatically. PLANNING If you have unfiled years, completing a streamlined compliance filing before you expatriate lets you sign the certification truthfully and removes the single most common accidental trigger.
Strategy 3: Time the departure
RULE Green-card holders are subject only as long-term residents, at 8 of the last 15 years. PLANNING Leaving before year 8 avoids the exit tax entirely; see the green card guide. For everyone, avoiding a departure year with an unusually large tax bill or realized gains helps with the income test.
Strategy 4: Use the residency-date basis step-up
RULE Under IRC §877A(h)(2), if you became a US citizen or resident later in life, you may treat the fair market value of certain assets on the date you became a US person as your basis for the deemed sale. PLANNING This can sharply reduce the gain that counts, but the exact assets and valuations need professional confirmation.
What does not work
DO NOT Filing a false certification, hiding accounts, or backdating gifts is not planning, it is fraud, and it carries far worse consequences than the exit tax. Renouncing does not erase past US tax obligations, and a defective Form 8854 can make you covered anyway. Legitimate planning happens openly and before you expatriate, with advice from a qualified CPA or tax attorney.
Model your own numbers in the exit tax calculator, then confirm the approach with a professional. If you may make gifts to US family later, also read Section 2801.
