Renouncing U.S. citizenship does not erase tax obligations. The recent arrest of cryptocurrency entrepreneur Roger Ver in Spain illustrates how the Internal Revenue Service (IRS) can trace undeclared crypto assets years after a person has expatriated, leading to substantial tax‑fraud charges.
The Roger Ver case
- In 2014 Ver renounced his U.S. citizenship while holding roughly 131,000 BTC.
- At the time of renunciation the Bitcoin were valued at about $871 per coin, giving him over $100 million in undisclosed assets.
- The IRS later determined that the tax on those assets exceeded $50 million.
- In 2024 Spanish authorities arrested Ver on U.S. tax‑fraud charges after the Treasury’s forensic tools linked the missing Bitcoin to him.
U.S. expatriation tax rules
- When a U.S. person renounces citizenship, they must file a final “exit” tax return (Form 8854) reporting all worldwide assets as of the date of expatriation.
- The tax is assessed on the fair market value of those assets on the renunciation date, not on the cash actually paid.
- Payment is due the following tax year, not on the day of the renunciation.
- Individuals whose net worth exceeds the $2 million “covered expatriate” threshold (or who meet the tax‑liability test) are subject to the exit tax; those below the threshold may avoid it.
Reporting requirements
- Real estate, foreign bank accounts, trusts, corporations, and crypto holdings must all be disclosed.
- Declaring assets in a hardware wallet, ledger, or other “offline” storage does not exempt them from reporting.
- Failure to file the required Form 8854 or to disclose assets can trigger tax‑fraud investigations that may continue for years, as demonstrated by the Ver case.
Risks of non‑compliance
- The IRS employs blockchain‑analysis tools capable of tracing cryptocurrency transactions across exchanges and wallets.
- Lifestyle indicators—such as private‑jet travel, yacht purchases, or high‑value real‑estate acquisitions—can prompt audits if declared assets appear insufficient.
- Penalties can include civil fines, criminal charges, and seizure of assets.
- Even modest undeclared amounts (e.g., $5‑$6 million) have led to prosecutions, as seen with other high‑profile cases.
Practical steps for anyone considering renunciation
- Engage a U.S. tax attorney experienced in expatriation to assess liability and prepare the exit return.
- Compile a complete inventory of all assets, including:
- Cryptocurrency balances and their fair‑market values on the renunciation date.
- Foreign bank accounts, securities, real‑estate holdings, and ownership interests in foreign entities.
- File Form 8854 on time and pay any assessed tax in the subsequent filing year.
- Avoid reliance on “offline” storage as a shield; disclose all holdings regardless of custody method.
- If net worth is below the $2 million threshold, verify whether the “covered expatriate” test applies, which could eliminate the exit tax.
- Consider the timing of renunciation relative to market conditions; a lower asset valuation at the time of expatriation reduces the taxable base.
Renouncing U.S. citizenship without proper tax compliance can result in long‑term legal exposure. Accurate reporting and professional guidance are essential to avoid the severe consequences demonstrated by recent enforcement actions.
