If you're a US citizen or Green Card holder living abroad, or a US-based investor with international assets, “offshore” doesn't mean secret — it means reportable. Here's exactly what's legal, what must be disclosed, and how cross-border money actually moves in 2026.

The Core Rule: US Persons Are Taxed on Worldwide Income
Unlike most countries, the US taxes its citizens and Green Card holders on worldwide income regardless of where they live — this is called citizenship-based taxation, and it makes the US almost unique globally. Holding a foreign bank account, foreign brokerage account, or foreign crypto wallet is completely legal — but it comes with mandatory reporting obligations that many newcomers to international living don't realize apply to them.
FBAR: The Foreign Bank Account Report
If the combined value of your foreign financial accounts exceeds USD 10,000 at any point during the calendar year, you must file an FBAR (FinCEN Form 114) — even if the accounts never held that much individually, and even if you never earned any taxable income from them. This applies to bank accounts, brokerage accounts, and certain foreign retirement or pension accounts.
How and when it is filed
- Filed separately from your tax return, directly with FinCEN, by April 15 (with an automatic extension to October 15).
- Penalties for non-willful failure to file can reach up to USD 10,000+ per violation (adjusted annually for inflation); willful failures carry far steeper penalties, including potential criminal referral.
- Filing an FBAR is not optional once the threshold is crossed — it applies regardless of whether the money is “innocent” savings or investment income.
FATCA: Reporting Requirements Layered on Top
FATCA (Foreign Account Tax Compliance Act) requires foreign financial institutions to report US account holders directly to the IRS, and separately requires US taxpayers to file Form 8938 with their tax return if foreign assets exceed certain thresholds (which vary based on filing status and whether you live in the US or abroad — thresholds are notably higher for Americans living overseas).
The practical result: foreign banks in FATCA-participating countries already report your account to the IRS independently of what you file yourself — meaning US persons who fail to self-report are not relying on secrecy, since the information is likely already flowing to the IRS through the bank itself.
CRS 2.0: The Global Net Just Got Wider (2026 Update)
The Common Reporting Standard (CRS), the international counterpart to FATCA, now covers 116+ jurisdictions exchanging financial account information automatically. The major 2026 development: CRS 2.0 now extends to crypto-assets, closing what was previously the largest gap in global financial transparency. Crypto exchanges in participating jurisdictions must begin collecting reportable data from January 1, 2026, with the first international data exchanges expected in 2027.
Where the US fits in
Important nuance: the US itself doesn't participate in CRS as a full reporter — it uses FATCA instead — but the US does receive information under reciprocal FATCA agreements, and virtually every other country a US person might bank in does participate in CRS. In practice, this means a US person's foreign accounts are visible to the IRS through one channel or another almost everywhere in the world.
Cryptocurrency: Now Fully in Scope
Crypto held on foreign exchanges may trigger both FBAR and FATCA reporting obligations, and the IRS treats cryptocurrency as property for tax purposes — meaning every sale, trade, or crypto-to-crypto swap is a potentially taxable event requiring capital gains reporting. With the 2026 CARF (Crypto-Asset Reporting Framework) rollout beginning, foreign exchange activity is increasingly visible to tax authorities directly from the exchange, not just from voluntary disclosure.
Legal Ways to Move Money Across Borders
- Bank wire transfers — reliable and traceable, though often with higher fees and less competitive exchange rates than specialized services.
- Regulated money transfer services (Wise, OFX, Xe) — typically better exchange rates for large transfers, with clear digital documentation useful for both compliance and your own records.
- Brokerage transfers — moving investment assets between US and foreign brokerage accounts, subject to both firms' compliance procedures.
A general compliance principle worth understanding: any transfer method that's fast, transparent, and produces a paper trail is inherently more defensible than one designed to avoid detection — and given how comprehensive CRS/FATCA reporting has become, there is effectively no way to move meaningful sums internationally without it eventually being visible to tax authorities regardless of the method chosen.
Common Misunderstandings Worth Clearing Up
“Offshore” doesn't mean illegal
Holding a foreign bank account is completely legal for US persons — the legal obligation is disclosure, not avoidance of foreign banking itself.
Small balances still count
A foreign account with modest balances still requires reporting once the FBAR threshold is crossed, even briefly during the year.
Foreign retirement accounts are often reportable too
Many countries' pension-equivalent accounts don't get the same tax-deferred treatment the IRS gives US retirement accounts, creating reporting and sometimes taxation complexity that catches expats off guard.
Application Checklist
- Determine whether your combined foreign account balances exceeded USD 10,000 at any point in the year.
- File FBAR (FinCEN Form 114) if the threshold was crossed, separately from your tax return.
- Check whether Form 8938 (FATCA) reporting also applies based on your specific asset thresholds.
- Report all crypto transactions, including crypto-to-crypto trades, as potentially taxable events.
- Use regulated, well-documented transfer services for cross-border transfers to maintain a clear compliance trail.
- Consult a CPA or tax attorney experienced in expat/international tax if your situation involves foreign retirement accounts, trusts, or business ownership.

Quick Answers
Q.Do I need to report a foreign account if I never earned interest on it?
Yes — the FBAR filing requirement is based on the account balance threshold, not on whether you earned taxable income from it.
Q.Is it illegal to have a foreign bank account as a US citizen?
No — it's entirely legal. The legal requirement is disclosure through FBAR and, where applicable, FATCA Form 8938, not a prohibition on foreign banking.
Q.Does CRS 2.0 mean the IRS will now see my crypto exchange activity automatically?
For exchanges in CRS/CARF-participating jurisdictions, increasingly yes, starting with data collection from January 1, 2026 and first exchanges in 2027 — this is a significant shift from crypto's earlier relative reporting opacity.
