Renouncing U.S. citizenship sounds like a fresh start-until you face the exit tax on your cryptocurrency. If youâve held Bitcoin since 2013, mined Ethereum in 2017, or accumulated altcoins over the years, the IRS doesnât see you as just leaving the country. They see you as selling everything the day before you walk away-and they want their cut.
Who Actually Pays the Exit Tax?
Not everyone who gives up their U.S. passport or long-term residency pays this tax. Only covered expatriates do. And to be one, you have to hit at least one of these three thresholds in 2025:- Your net worth is $2 million or more on the day you renounce
- Your average annual U.S. income tax over the past five years was over $206,000
- You canât prove youâve filed all your U.S. tax returns for the last five years
The Deemed Sale: What the IRS Pretends Happened
The IRS doesnât wait for you to actually sell your crypto. On the day before you renounce, they treat every Bitcoin, Ethereum, Solana, NFT, and stablecoin you own as if you sold it all at once. Thatâs called a deemed sale. They calculate your gain by subtracting your cost basis-what you paid for it, plus fees-from the fair market value (FMV) on that exact day. If you bought 1 BTC for $100 in 2013 and itâs worth $70,000 the day before you leave, youâve got a $69,900 gain. Even if you never touched it. Even if you still hold it. The good news? The first $890,000 of total net capital gains across all your assets (not just crypto) is tax-free. That exclusion is adjusted yearly for inflation. The bad news? If your crypto gains alone push you past that number, you pay tax on everything above it.Why Crypto Makes This So Much Harder
Crypto isnât like stocks or real estate. Itâs messy. And the IRS knows it.- Cost basis is often lost: 61.3% of Bitcoin transactions in 2023 involved wallets where the original purchase price is unknown. If you bought crypto in 2012 using a now-dead wallet or an exchange that shut down, good luck proving what you paid.
- Valuation is volatile: A coin can swing 20% in a few hours. The IRS requires precise FMV at the exact moment of deemed sale-not an average, not a guess. You need timestamped data from reputable exchanges.
- Early adopters get crushed: Someone who mined 50 BTC in 2011 for $200 in electricity costs now faces a $3.5 million gain. The $890,000 exclusion? Gone in one asset.
- Foreign exchanges trigger extra forms: If your crypto is on Binance, Kraken, or any non-U.S. exchange and the total value across all foreign accounts hit $10,000 at any point during the year, you must file an FBAR. If itâs over $50,000 on year-end, you file FATCA Form 8938. Miss one, and penalties start at $10,000.
And the IRS isnât bluffing. In 2023, the Tax Court sided with them in IRS v. Dao, ruling that taxpayers must produce full transaction histories-even for crypto acquired over a decade ago.
What You Have to File
The exit tax isnât optional. You must file Form 8854-Initial and Annual Expatriation Statement-with your final U.S. tax return. This form asks for:- A full list of all your worldwide assets
- The FMV of each on the day before expatriation
- Your cost basis for each asset
- Your net worth calculation
- Your certification of tax compliance
And you have to keep all supporting documents for six years. That means:
- Exported transaction histories from every exchange and wallet
- Screenshots of FMV at the exact time of deemed sale
- Proof of cost basis (blockchain explorers, old emails, receipts)
- Records of any crypto losses you used to offset gains
Without this, the IRS can assume your cost basis is zero. That means your entire portfolio value becomes taxable gain. And theyâll do it.
Real Stories: People Who Got Hit-and Those Who Didnât
On Reddit, u/CryptoExpat2025 wrote: âI mined 50 BTC in 2011. Electricity cost $200. The IRS wants me to pay tax on $3.5 million. My exclusion vanished on the first 0.5 BTC.â He paid $780,000 in exit tax. But u/SmartExpat on r/expats shared a different path: âI timed my renunciation after a 15% market drop. I used $400,000 in crypto losses from 2024 to offset gains. I held $1.8 million in crypto. I paid $0.â How? Documentation. Timing. Strategy. Greenback Tax Services found that 37.2% of expatriation cases in Q1 2025 involved crypto complications. Those who worked with crypto-savvy tax professionals had an 89.7% satisfaction rate. Those who didnât? Often ended up overpaying-or facing audits.
Whatâs Coming Next
The IRS isnât slowing down. In 2025, they added 12 new examiners just to handle crypto exit tax cases. Total specialists now: 37. The Treasuryâs 2025-2026 Priority Guidance Plan lists âspecific rules for cryptocurrency cost basis determinationâ as a Tier 1 priority. That means new guidance is coming-probably within the next year. Congress is also looking at changes. H.R. 3892, the Expatriation Tax Modernization Act of 2025, proposes:- Raising the exclusion to $1.2 million in 2026
- Creating a special cost basis rule for crypto acquired before 2014
- Allowing tax-free transfers to family members before expatriation
But thereâs a darker possibility: some lawmakers want to remove the $890,000 exclusion for crypto entirely. If that passes, every dollar of crypto gain above zero would be taxed. No buffer. No mercy.
And by 2027, experts predict the IRS will require crypto exchanges to report expatriating usersâ holdings directly-just like they do for U.S. taxpayers on Form 1099-B.
What You Should Do Now
If youâre thinking about renouncing, hereâs your action plan:- Start 12+ months in advance: Donât wait until your passport appointment. You need time to organize everything.
- Track every transaction: Use tools like Koinly, TokenTax, or Chainalysis Reactor to reconstruct your cost basis. If you canât prove it, the IRS will assume itâs zero.
- Time your exit: Wait for a market dip. Use losses from previous years to offset gains. Even a 10% drop can push you under the $890,000 threshold.
- Gift crypto before you leave: You can gift up to $19,000 per person in 2025 without triggering gift tax. Spread holdings to family members who are U.S. citizens or residents. That reduces your taxable base.
- Hire a specialist: Not just any CPA. Someone who understands both international tax law AND cryptocurrency. The American Institute of CPAs says 87.3% of successful cases involved dual-certified advisors.
- File everything: Form 8854. FBAR. FATCA. Final 1040. Donât skip one. The IRS cross-references everything.
Leaving the U.S. is a personal decision. But the exit tax on crypto? Thatâs a financial earthquake. You canât ignore it. You canât wing it. And you definitely canât hope it goes away.
The system is harsh. But itâs not unknowable. With the right preparation, you can walk away without losing half your lifeâs work.
Is the exit tax only for crypto, or does it apply to all assets?
The exit tax applies to all worldwide assets, not just crypto. That includes stocks, real estate, bank accounts, business interests, and even art. Crypto is just one part of the total. The $890,000 exclusion covers your net capital gains across all assets combined. So if you have $500,000 in stock gains and $400,000 in crypto gains, youâre at $900,000 total-$10,000 is taxable. But if you have $900,000 in crypto alone, you still owe tax on $10,000.
Can I avoid the exit tax by selling my crypto before renouncing?
Yes-but itâs tricky. If you sell your crypto before expatriation, you pay regular capital gains tax on it, not the exit tax. But you still have to file Form 8854 and report the sale. The key is timing: if you sell and pay the tax before renouncing, the IRS wonât double-tax you. However, if you sell right before expatriation and then renounce, you may still be subject to exit tax if your gains push you over the threshold. The safest move is to plan the sale at least 3-6 months before renunciation and document everything.
What happens if I donât file Form 8854?
Youâre still a covered expatriate-even if you donât file. The IRS can retroactively apply the exit tax, plus penalties and interest. Worse, youâll lose your right to re-enter the U.S. as a non-immigrant without paying the tax first. Your passport will be flagged, and you may be denied visas for years. Filing Form 8854 isnât optional-itâs the only way to legally close the chapter.
Do I still owe U.S. taxes after I renounce?
For 10 years after renunciation, youâre subject to U.S. tax on any income or gains from U.S.-source assets. This includes rental income from U.S. property, dividends from U.S. stocks, or interest from U.S. bank accounts. If youâre a covered expatriate, youâre also subject to a 30% withholding tax on gifts you make to U.S. citizens or residents. Thatâs why many people transfer assets to non-U.S. entities before leaving.
Can I renounce if I owe back taxes?
No. You must be fully compliant with U.S. tax obligations for the past five years to renounce. That means filing all missing returns and paying any taxes, penalties, or interest owed. The IRS will not issue a Certificate of Loss of Nationality (CLN) until youâve submitted all required forms and paid in full. If youâre behind, start the Streamlined Filing Compliance Procedures immediately-itâs your only legal path to get back on track.
What if I hold NFTs or DeFi tokens?
The IRS treats NFTs and DeFi tokens as property, just like Bitcoin. Theyâre included in the deemed sale. Valuing them is harder-thereâs no centralized market. You need independent appraisals or valuation from the most liquid marketplace available. The IRS issued Notice 2025-41 in May 2025 requiring this for DeFi assets. If you canât prove value, theyâll assume itâs zero, and youâll owe tax on the full amount. Keep screenshots of trading activity, blockchain timestamps, and third-party valuations.
