Do US expats owe US tax on cryptocurrency gains?

Yes. US citizens and green card holders are taxed on worldwide income regardless of residency. Cryptocurrency is property under IRS Notice 2014-21 — gains are taxable in the US whether you live in London, Dubai, or Singapore. The Foreign Earned Income Exclusion does NOT apply to investment gains; it covers only foreign earned income (wages, self-employment). The Foreign Tax Credit may offset US tax if your country of residence taxes crypto gains, but low-tax and no-tax countries (UAE, Singapore) provide no FTC relief.

Do I need to report crypto on my FBAR?

Under current FinCEN guidance (Notice 2020-2), accounts holding ONLY virtual currency at a foreign exchange are NOT required to be reported on the FBAR. However, if a foreign exchange account holds both fiat currency (USD, EUR, GBP) and crypto, the fiat balance determines whether the account crosses the $10,000 FBAR threshold. Note: FinCEN proposed rulemaking would extend FBAR to pure crypto accounts, but as of mid-2026 no final rule has been published. Many practitioners report foreign crypto accounts anyway as a risk-reduction measure.

Does the wash sale rule apply to crypto?

No. IRC Section 1091 (the wash sale rule) applies only to stock and securities. The IRS classifies cryptocurrency as property — not stock or securities — so you can sell crypto at a loss and immediately rebuy the same coin without losing the deduction. This is a tax-loss harvesting advantage that stock investors do not have. Note: legislation to extend wash sale rules to digital assets has been proposed repeatedly but had not been enacted as of mid-2026. The law could change.

What happens to my crypto if I renounce US citizenship?

If you are a covered expatriate (net worth $2M+, average annual US tax $211K+, or 5-year compliance failure), IRC §877A treats all your property — including cryptocurrency — as deemed sold at fair market value on the day before your expatriation date. Unrealized gains above the $910,000 exclusion (2026) are taxable. The valuation challenge is significant: you need a snapshot of every wallet and exchange balance on that specific day. Pre-renunciation planning (timing, harvesting losses, Roth conversions) can dramatically reduce the bill.

Cryptocurrency Taxes for US Expats: 2026 Complete Guide

US citizens abroad hold crypto in wallets on three continents, trade on foreign exchanges, stake in DeFi protocols — and still owe the IRS. But the questions go well beyond capital gains rates: FBAR obligations for Binance International, FATCA reporting for foreign exchange accounts, exit tax on unrealized Bitcoin gains when you renounce, and PFIC risk in foreign crypto funds. Here is the complete picture for 2026.

2026 key numbers. Short-term crypto gains: taxed as ordinary income (10–37%).¹ Long-term crypto gains (held >1 year): 0%, 15%, or 20% + 3.8% NIIT.¹ FBAR threshold: $10,000 aggregate in foreign financial accounts — pure crypto-only foreign exchange accounts are currently not required under FinCEN Notice 2020-2.² Exit tax exclusion: $910,000 aggregate gain for covered expatriates (§877A, 2026).³ Form 1099-DA basis reporting: required from US brokers for 2026 transactions onward.⁴

Crypto is Property, Not Currency — What That Means for You

IRS Notice 2014-21 established that cryptocurrency is treated as property for US federal tax purposes, not as foreign currency.¹ This single classification drives most of the tax consequences:

Every disposal is a taxable event. Selling, trading crypto-for-crypto, using crypto to buy goods or services, receiving crypto as payment — all generate a gain or loss measured in US dollars.
Holding period governs the rate. Hold longer than one year: long-term capital gains rates (0/15/20%). Hold one year or less: short-term rates (ordinary income, same bracket as wages — up to 37% in 2026).
Not §988 foreign currency treatment. If you hold euros in a foreign bank account and the dollar weakens, the gain on the euros is ordinary income under §988. Bitcoin is different — it is property, not a "foreign currency" under the Code. USD-denominated gains on crypto are §1001 capital gains.
FEIE does not help. The Foreign Earned Income Exclusion (§911) covers only earned income — wages and self-employment profits. Capital gains, including crypto gains, are investment income. You cannot FEIE away a $300,000 Bitcoin gain even if you live entirely outside the US.
Staking rewards are ordinary income when received. Rev. Rul. 2023-14 confirmed that staking rewards are included in gross income at fair market value when received.⁵ This income is not earned income, so again, FEIE does not shelter it.

No Wash Sale Rule — The Tax-Loss Harvesting Advantage

IRC Section 1091 (the wash sale rule) prohibits claiming a loss on a security sale if you buy the same or substantially identical security within 30 days before or after the sale. Section 1091 applies to stock and securities — and cryptocurrency is property, not a security.

As of mid-2026, the wash sale rule does not apply to cryptocurrency.⁶ This means:

You can sell Bitcoin at a loss and immediately rebuy the same amount of Bitcoin. The loss is deductible against your other capital gains.
You can harvest losses to offset gains from other assets (stocks, real estate proceeds, other crypto positions).
For US expats with large unrealized losses in crypto — common after 2022-style drawdowns — this is a significant planning lever that US stock investors don't have.

Legislative risk. Bills to extend wash sale rules to digital assets have been introduced repeatedly in Congress (including in 2021 and 2023). None had been enacted as of mid-2026. This rule could change. If you are executing a substantial loss-harvesting strategy, be aware that legislation could be enacted mid-year with retroactive effect.

FBAR: Do You Report Your Foreign Crypto Exchange?

The FBAR (FinCEN 114) requires US persons to report foreign financial accounts with aggregate balances exceeding $10,000 at any point during the year. The critical question: does your Binance International, Coinbase International, or Kraken non-US account count?

The current answer is fact-specific:

Account type	FBAR required?
Foreign exchange account holding ONLY cryptocurrency	Currently No under FinCEN Notice 2020-2²
Foreign exchange account holding fiat currency (USD, EUR, USDT, USDC) + crypto	Yes if fiat+stablecoin aggregate >$10,000 — the account is a reportable foreign financial account
Foreign bank account that also allows crypto purchases (some UK/EU neo-banks)	Yes — the underlying bank account is reportable regardless of crypto balance
Non-custodial wallets (MetaMask, hardware wallets)	No — not a "financial account at a foreign financial institution"

Proposed rule — not finalized. FinCEN issued a Notice of Proposed Rulemaking in December 2020 that would extend FBAR to foreign accounts holding only virtual currency. As of mid-2026, no final rule has been published.² If finalized, it would require reporting foreign crypto exchange accounts with crypto value exceeding $10,000. Many expat tax practitioners recommend reporting foreign crypto exchanges voluntarily even without a legal requirement, to preserve good-faith clean-hands position if the rule is later finalized retroactively.

Practical tip: if you hold any USD, USDC, USDT, or other fiat/stablecoin at a foreign exchange, that fiat balance is the starting point for FBAR analysis. A Binance account with $12,000 of USDC and $50,000 of BTC is clearly a reportable account under existing rules — the fiat crosses the threshold.

Form 8938 (FATCA): Foreign Financial Asset Reporting

Form 8938 (Statement of Specified Foreign Financial Assets) is attached to your Form 1040 and requires reporting foreign financial assets above the following thresholds:

Single or MFS filing from abroad: >$200,000 on last day, or >$300,000 at any time during year
MFJ filing from abroad: >$400,000 on last day, or >$600,000 at any time during year
(Lower thresholds apply if you reside in the US: $50K/$75K single, $100K/$150K MFJ)

IRS guidance on whether cryptocurrency at a foreign exchange constitutes a "specified foreign financial asset" under §6038D remains ambiguous as of 2026. The IRS has not issued a definitive ruling. The practical approach most conservative practitioners take: if you hold cryptocurrency at a foreign exchange in amounts that would exceed Form 8938 thresholds if it were clearly reportable, file anyway. The penalty for failure to file ($10,000–$50,000) vastly outweighs the cost of a precautionary filing.

Form 1099-DA: The IRS Knows More Than You Think

Starting in 2025, US custodial cryptocurrency brokers (Coinbase, Kraken US, Gemini, etc.) are required to issue Form 1099-DA reporting gross proceeds from digital asset transactions.⁴ Starting with 2026 transactions, brokers must also report cost basis on covered transactions.

What this means for US expats:

Your US exchange activity will be matched to your return. If you sold $80,000 of Bitcoin on Coinbase in 2025 and didn't report it, the IRS will see the 1099-DA and will send a notice. The age of undetected crypto gains is effectively over for US-based exchanges.
Foreign exchanges don't issue 1099-DA — that reporting requirement applies only to US brokers. However, the IRS uses treaty information exchange (FATCA, FBAR, international agreement) to close this gap. Don't assume non-reporting by the exchange means non-detection.
Cost basis tracking is your responsibility for foreign exchange activity. If you moved BTC from Coinbase to Binance International and then sold it, your original Coinbase cost basis needs to follow the coins. Expats who have used multiple wallets and exchanges across different countries often face a forensic accounting exercise to reconstruct basis accurately.
Specific identification vs. FIFO. You can use specific identification to choose which coins you're selling (to minimize gain or maximize loss). But you must designate at the time of sale and maintain records. FIFO is the default if records are absent.

How the Foreign Tax Credit Applies to Crypto

If your country of residence taxes cryptocurrency gains, those foreign taxes may be creditable against your US tax liability under §901 (Form 1116, passive income basket). This is the mechanism that prevents double taxation for US expats in countries with crypto CGT.

Country	Crypto CGT treatment (2026)	FTC analysis for US expats
United Kingdom	10% (basic rate) or 20% (higher rate) CGT on gains above the £3,000 annual allowance	FTC-creditable. UK at 20% vs US at 23.8% (20%+NIIT) = small residual US bill for high-income earners in higher-rate band
Germany	~25% flat Abgeltungsteuer + solidarity surcharge (≈26.375%) on crypto gains as of proposed 2026 legislation — see note	If German tax applies, FTC fully offsets US LTCG rate (23.8%) with possible small excess
Australia	Full CGT applies; 50% CGT discount for assets held >12 months (effective rate up to 22.5% for highest bracket)	Australian CGT is FTC-creditable but the 50% discount means the Australian effective rate may be below US LTCG rate — residual US bill possible
Canada	Capital gains included at 50% inclusion rate (pre-June 2024 rule); 2/3 inclusion rate for gains above C$250K/yr (post-June 2024)	Canadian tax on crypto gains is FTC-creditable. Effective Canadian rates may be below US 23.8% top LTCG — verify your marginal rates
Singapore	No CGT — gains are tax-free unless you are in the business of trading crypto (income tax then applies)	No FTC available. Full US CGT applies. For large long-term crypto gains, 0% Singapore + 23.8% US = full 23.8% rate
UAE	0% — no personal capital gains tax	No FTC available. Full US CGT applies. Living in Dubai doesn't reduce your US crypto tax bill at all
Portugal	28% flat rate on crypto gains held <365 days; 0% for >365 days (individual investors)	For short-term gains: 28% Portuguese tax → FTC offsets US 37% ordinary rate, leaving ~9% residual. For >365 days: 0% Portuguese tax → full US LTCG at 23.8% applies. The 0% Portuguese rule mirrors the FEIE trap — no tax abroad = no FTC = full US bill
Japan	Miscellaneous income (雑所得), combined national + local rates up to 55.9%	FTC-creditable. Japanese rates fully offset US rates. Expats in Japan may owe no US tax on crypto gains if Japanese tax exceeds US rate
France	PFU (Prélèvement Forfaitaire Unique) flat 30% (12.8% income tax + 17.2% social charges)	Social charges (CSG/CRDS) — FTC creditability is contested but generally credited post-2020 guidance. At 30% French vs 23.8% US LTCG: French FTC should fully offset

Germany crypto tax update — verify before relying. Germany's traditional rule (crypto held >1 year = tax-free) has been under legislative challenge. Multiple sources indicate a proposed change in 2026 to apply a ~25% flat capital gains tax to crypto regardless of holding period, bringing it in line with other capital assets. This change had not been fully confirmed across all sources as of this writing. If you are an expat in Germany with large long-term crypto positions, verify the current rule with a German tax adviser before assuming the 1-year exemption still applies. If the traditional rule still applies, German-source crypto gains held >1 year are not taxed — meaning no FTC is available, and your full US LTCG rate applies.

Exit Tax: Crypto and Renunciation

If you are considering renouncing US citizenship and you are a covered expatriate, IRC §877A treats all your property — including every coin in every wallet and on every exchange — as deemed sold at fair market value on the day before your expatriation date.³

What "all property" includes:

Bitcoin, Ethereum, and all other tokens
Stablecoins (USDC, USDT, DAI) — typically no gain, but must be valued
DeFi protocol positions (liquidity pool tokens, yield-bearing positions)
NFTs with appreciated value
Crypto held in US IRAs — these follow the separate IRA deemed-distribution rule under §877A(f)

The practical challenge: you need a precise FMV snapshot of every wallet and account at the close of business the day before your expatriation date. For someone with 15 wallets, staked positions, LP tokens in DeFi protocols, and accounts on three exchanges, this is a significant forensic exercise. The $910,000 aggregate exclusion (2026) applies against all your property net gains combined — not $910,000 per asset.

Pre-renunciation planning for crypto holders. Harvest realized losses before expatriation (they reduce your exit tax exposure). Consider whether a Roth conversion earlier — while crypto prices were lower — reduces the IRA deemed-distribution exposure. Review whether selling appreciated positions and paying LTCG in the year before expatriation (removing the unrealized gain) is better than paying exit tax on it. The math depends on whether you would be a covered expatriate at all — run the three tests first.

The PFIC Trap in Crypto Products

The PFIC rules (§1291–§1298) that devastate US expats holding foreign mutual funds also lurk in certain crypto products. The key distinction:

Holding crypto directly (BTC in a wallet, ETH on an exchange) — not a PFIC. You own property directly.
US-listed Bitcoin/Ethereum spot ETFs (launched January 2024) — these are SEC-registered investment companies, which are explicitly excluded from PFIC treatment under §1297(e)(1). Not PFICs.
Foreign crypto funds, crypto index funds, or fund-like products on foreign exchanges — these may be PFICs if they are treated as foreign corporations that hold primarily passive assets (which crypto arguably is for the fund entity). This analysis is unsettled, but the conservative conclusion is that foreign fund wrappers around crypto exposure carry PFIC risk.
DeFi liquidity pools and protocol tokens — the PFIC classification of DeFi protocol interest is entirely unsettled. Treat positions with foreign entities carefully.

The safest approach for US expats who want crypto exposure: hold coins directly or use US-listed ETFs (Fidelity Wise Origin, iShares Bitcoin Trust, etc.). Avoid fund-like wrappers from foreign exchanges or locally domiciled crypto funds.

Pre-Move Checklist: Crypto Before You Leave the US

If you are moving abroad, your crypto portfolio deserves specific attention before departure:

Reconstruct your cost basis now. If you've been in crypto since 2017 and your records are scattered across five exchanges, fix this before you move. Once you're abroad and exchanges have different reporting obligations, reconstruction becomes harder and more expensive.
Harvest gains at 0% if eligible. If your 2026 taxable income (after FEIE for earned income, deductions, etc.) puts you in the 0% long-term capital gains bracket, consider realizing gains before moving to a country that taxes capital gains. You may not get that 0% window back.
Harvest losses before the wash sale window matters. Losses can be harvested freely (no wash sale). If you have positions in the red, harvesting them before a major life event or move cleans up the basis.
Sever state domicile before any large sale. California taxes capital gains at up to 13.3% with no reduced rate for long-term. A $500,000 Bitcoin sale while technically a California domiciliary could add $65,000 in California tax. Sever California domicile before the sale — this requires more than just leaving; see the state residency planning guide for the 9-factor domicile test.
Review which exchanges you use. Once abroad, moving to a foreign exchange for convenience creates FBAR complexity. Consider whether keeping assets on US-registered platforms is simpler compliance-wise.
Transfer cost basis documentation to records you control. Exchange records get deleted. Download transaction histories for every exchange you've ever used and store them somewhere permanent.

How a Specialist Adviser Helps

Most US CPA firms decline to advise non-resident clients (FATCA compliance risk for the firm). Most foreign advisers have never heard of Rev. Rul. 2023-14 or the PFIC rules. The narrow specialty — US-licensed, fee-only, experienced with both US cross-border tax and cryptocurrency — is exactly the combination that serves this situation.

A specialist can:

Model the FTC analysis for your specific country and rate situation
Evaluate whether your foreign exchange accounts trigger FBAR reporting
Run the exit tax calculation if you are considering renunciation
Identify which of your holdings create PFIC exposure and how to restructure
Build a tax-loss harvesting schedule that respects the wash sale non-applicability while setting up FTC carryforwards
