Crypto Taxes for US Expats: Reporting, Transfers Across Borders, and FBAR/8938 Traps

Crypto makes an already-confusing expat tax picture worse, because two things collide: the US taxes its citizens on worldwide income, and crypto generates taxable events in places people don't expect. If you're a US person trading or holding crypto abroad, the IRS is part of the story whether your coins sit on a US or a foreign platform.

This guide covers how crypto is taxed for US expats, what actually counts as a taxable event, the cross-border transfer questions, and the FBAR/Form 8938 reporting traps that come with foreign exchanges.

The starting point: crypto is property, taxed worldwide

The US treats cryptocurrency as property, not currency. So disposing of crypto triggers capital gain or loss, and earning crypto (staking, mining, rewards, airdrops, payment for work) is generally ordinary income at its value when received. Because taxation follows your citizenship, you report these to the US regardless of where you live — and the FEIE doesn't help, since crypto gains aren't "earned income."

"If I cash out to my US account, where do I pay tax?"

The bank account is a red herring. What creates the tax is the disposal — selling the crypto, or swapping it for another coin — not which account the resulting cash lands in. So:

• As a US citizen, you report the gain to the US wherever you live, and whichever account you cash out to.
• Your country of residence may also tax that gain under its own rules — potentially creating double taxation.
• The Foreign Tax Credit or a tax treaty can usually relieve that double tax, so you're not paying full freight twice.

In short: cashing bitcoin into your US account doesn't make it "US-only" income or "foreign" income — the disposal is taxable to the US because you're a citizen, and your residence country gets its own say.

Which transfers are taxable — and which aren't

• Moving your own crypto between your own wallets or exchanges — not a taxable event. Sending BTC from a foreign exchange to your own cold wallet changes nothing for tax.
• Selling crypto for fiat, or swapping one coin for another — taxable; you realize gain or loss.
• Moving fiat across borders (e.g. wiring euros into a US bank) — not itself a taxable event; it's the underlying disposal that was taxable, not the bank transfer.

People conflate the money movement with the taxable event. The transfer of value across a border doesn't create tax; the sale or swap that happened (whenever it happened) does.

The FBAR and Form 8938 traps with foreign exchanges

Holding crypto on a foreign exchange raises the same questions as any other foreign account — and the rules here are genuinely in flux:

• FBAR (FinCEN 114): historically, a foreign account holding only crypto wasn't clearly FBAR-reportable, but FinCEN has signaled it intends to bring foreign crypto accounts into scope. If a foreign account holds crypto and fiat, the fiat side can already push you over the $10,000 line.
• Form 8938 (FATCA): foreign-held crypto can be a specified foreign financial asset depending on how it's held — more likely when held through a foreign account or entity than in a self-custodied wallet.
