Compliance · The tax-and-paperwork side

Cross-border tax filing — for any corridor.

Most US-tax obligations on international transfers are corridor-agnostic — they apply to a US person with accounts or recipients in any foreign country. The thresholds, forms, and deadlines stay the same whether the money goes to India, Mexico, Philippines, the UAE, or the UK. Below: the US filings, then country-specific notes.

The single threshold most senders miss

If you are a US person with combined foreign account balances exceeding $10,000 at any point during the year, you must file FBAR — regardless of which country those accounts are in. This catches more people than any other single rule.

United States · for any US sender or NRI

Four US filings that apply to every corridor.

FBAR · FinCEN 114

Combined foreign accounts over $10,000 → file.

Combined foreign accounts (savings, checking, fixed deposits, brokerage, retirement, insurance with cash value) exceeded $10,000 at any point during the year? Must file. Filed separately from your tax return. Joint accounts count. Applies to accounts in India (NRE/NRO/FCNR), Mexico (any Mexican bank account), Philippines (any local bank), UAE, UK, or anywhere else.
Potential penalty
Up to $16,536 per account / year (non-willful)
Deadline
April 15 · auto-extended to October 15

FATCA · Form 8938

Foreign financial assets over the threshold → file with 1040.

Foreign financial assets exceeded $50K (single) / $100K (married) on December 31? File Form 8938 with your 1040. Includes bank accounts, brokerage accounts, foreign mutual funds, foreign insurance with cash value, and foreign pensions. Threshold is higher than FBAR's — but you still file FBAR separately if you cross the $10K bar.
Potential penalty
$10K + $10K/30 days (up to $60K)
Deadline
With your tax return, April 15

Gift Tax · Form 709

Sent over $19,000 to one person in 2025 → file.

Sent more than $19,000 to any one person in 2025 (parents, siblings, friends, recipient — anyone except your US-citizen spouse)? Form 709 required. Likely no tax owed — the lifetime exemption is $13.99M — but the form must be filed. Transfers to a US-citizen spouse are unlimited and don't require Form 709.
Deadline
With your tax return, April 15

Large gifts received · Form 3520

Received over $100K from non-US persons → report.

Received gifts or inheritances totaling over $100K from non-US persons in the year? Must file Form 3520. No tax owed on the gift itself, but the penalty for non-filing is severe — up to 25% of the unreported amount. Common for US-based recipients of money from parents abroad.
Potential penalty
Up to 25% of unreported gift value

Country-specific notes

On top of US filings, each corridor has its own rules.

🇮🇳 India
LRS limit: $250K/year per Indian resident for outbound transfers. TCS: 5% on remittances above ₹7 lakh/year (0.5% if loan-funded education). Refundable when you file your ITR. India ITR: NRIs with India-sourced income (rent, capital gains, NRO interest) must file by July 31. NRE and FCNR interest is tax-free in India.

🇲🇽 Mexico
Recipient side: Personal remittances received from family abroad are generally not taxable in Mexico. Bitso and other crypto exchanges report transactions over MX$50,000 to SAT (the Mexican tax authority) automatically. SPEI deposits over MX$600,000 may trigger anti-money-laundering review at the receiving bank.

🇵🇭 Philippines
Recipient side: OFW (Overseas Filipino Worker) remittances are tax-exempt under Philippine law. Bank deposits over ₱500,000 from a single sender may trigger BSP (Bangko Sentral) reporting. No additional US filings beyond FBAR/FATCA if the recipient's account is in your name.
See today's USA → Philippines verdict →
🇦🇪 UAE
Sender side: No personal income tax in the UAE, so no UAE-side filing on remittances. Receiving in India: Same US/India rules apply (FBAR if your Indian-account balance crosses $10K). UAE banks and exchange houses (Al Ansari, LuLu, Sharaf) all report large transfers to UAE Central Bank — keep records of every transfer.
See today's UAE → India verdict →
🇬🇧 United Kingdom
Sender side (if UK-resident): No specific UK tax on outbound personal remittances. If US person resident in UK: still subject to all US filings above. Dual-tax avoidance: US-UK treaty exists — Form 8833 may be needed to claim treaty positions. HMRC notification not required for personal gifts under £325K/year.
See today's UK → India verdict →
₿ Crypto rail (any corridor)
US sender: Buying/selling USDC at $1.00 is not a taxable event. Bitcoin via Strike: each conversion is technically a sale, but for round-trip remittance the gain/loss is usually trivial. FBAR: Coinbase USD balances under $10K combined don't trigger FBAR; foreign-exchange (Bitso, Coins.ph) balances do.
