Frequently asked questions

Do I have to report international wire transfers to the IRS?

Not directly for most transfers. Your bank or money transfer provider files Currency Transaction Reports for cash transactions over $10,000. You personally must file FBAR if your foreign account balances exceed $10,000 at any point during the year, and Form 8938 if specified foreign assets exceed $50,000 (single filer). Routine international wires from your US bank account do not require a separate IRS filing unless those foreign accounts meet FBAR/FATCA thresholds.

What happens if I send more than $10,000 internationally?

If you send more than $10,000 in cash in a single day, your financial institution files a CTR — this is automatic and does not affect your ability to send. Electronic wire transfers (bank, Wise, crypto) do not trigger a CTR regardless of amount. However, all large transfers may trigger enhanced due diligence from your provider, and structuring multiple transfers to avoid the $10,000 threshold is illegal regardless of transfer method.

Does using crypto for remittance reduce my reporting obligations?

No — and in some cases it adds them. Crypto on-ramps like Coinbase and Kraken are registered Money Service Businesses and apply the same $3,000 Travel Rule record-keeping. Additionally, if you hold crypto on a foreign exchange (like Luno, Quidax, or Bitso) and the value exceeds $10,000 at any point during the year, you may have an FBAR obligation. The IRS also requires reporting of crypto-to-crypto and crypto-to-fiat transactions as taxable events.

What is the FBAR deadline and how do I file it?

FBAR (FinCEN Form 114) is due April 15 of the year following the reporting year, with an automatic extension to October 15. You file it electronically through FinCEN's BSA E-Filing System at bsaefiling.fincen.treas.gov — not with your tax return. There is no fee to file. You need the name of each foreign institution, the account number, the maximum value during the year, and the account type.

Are remittances to family members taxable in the US?

Money you send to family abroad is generally not deductible and is not taxable income for you — it comes from after-tax dollars. The recipient typically owes no US tax on personal gifts. However, if you receive a gift or inheritance from a foreign person totaling over $100,000 in a year, you must file IRS Form 3520 (informational, not a tax owed). If the remittances are for a business purpose (payments for services), different rules apply.
