Renouncing U.S. citizenship triggers a “mark‑to‑market” exit tax that treats all of a person’s worldwide assets as if they were sold on the day before expatriation. The tax is applied only to those who meet specific criteria and can be mitigated by careful planning.
When does the exit tax apply?
A person becomes a covered expatriate—and therefore subject to the exit tax—if any of the following conditions are met:
- Tax‑compliance test: The individual has not filed U.S. federal income tax returns for each of the five years preceding the renunciation.
- Net‑worth test: Total worldwide assets (minus liabilities) equal or exceed $2 million.
- Tax‑liability test: The individual’s average U.S. federal income tax liability for the five preceding years is about $160,000 per year (based on the tax brackets in effect at the time).
If none of these thresholds are reached, the expatriate is not considered “covered” and the exit tax does not apply.
How the tax is calculated
- Valuation date: The IRS determines the fair market value of every asset on the day before the renunciation oath.
- Deemed sale: All assets are treated as if they were sold at that value.
- Exemption: The first $700,000 of net capital gains is exempt from tax (adjusted annually for inflation).
- Tax rates:
- Gains classified as long‑term capital gains (assets held more than one year) are taxed at the long‑term capital‑gain rate (currently up to 20 %).
- Gains classified as short‑term (assets held less than a year) are taxed as ordinary income at the applicable marginal rate.
The tax is reported on the final U.S. income‑tax return filed after expatriation.
Assets that are included
- Cash and bank accounts – straightforward to value.
- Cryptocurrencies – generally easy to value at market prices on the valuation date.
- U.S. real estate – valued at fair market value; gains are subject to the same exemption and rates.
- Foreign real estate – also included, though valuation may be more complex in emerging‑market jurisdictions.
- Business interests – the value of a privately held company must be determined; portions of cash held within the business may be marked down, but the overall valuation is subject to IRS scrutiny.
The tax does not require the actual sale of the assets; the liability arises from the deemed sale.
Practical steps before renouncing
- Confirm five‑year filing compliance. Gather all U.S. tax returns for the past five years and ensure they are filed and accepted.
- Assess net worth. Compile a comprehensive list of assets and liabilities to determine whether the $2 million threshold is met.
- Consider net‑worth reduction strategies (e.g., gifting, charitable contributions, purchasing a second passport that may be counted as an asset reduction).
- Plan asset timing. Holding assets for more than a year before expatriation can qualify gains for the lower long‑term capital‑gain rate.
- Prepare valuation documentation. Keep records of market prices for cash, crypto, real estate, and business valuations to support the IRS‑reported figures.
What to expect after renunciation
If the exit tax applies, the individual will receive a $700,000 capital‑gain exemption and will owe tax on any remaining gains at the applicable rates. The tax is settled through the final U.S. tax return; no additional “exit‑tax” filing is required.
Because the exit‑tax rules can be amended by Congress, some expatriates choose to pay the tax rather than risk future changes that could increase the liability. Paying the tax does not preclude future residency or investment decisions, but it does close the U.S. tax‑compliance chapter for the individual.
