Sending Money to Thailand & the Foreign-Income Tax Rule (2026)

Bringing Money into Thailand

Whether you’re transferring savings to live on, receiving overseas income, or just topping up a Thai account, it pays to understand both the practical transfer options and the tax rules — which changed significantly in 2024.

Disclaimer note: Tax treatment of foreign income is complex and depends on your personal circumstances, your home country’s tax treaty with Thailand, and the source of the funds. This is general information, not tax advice. Consult a qualified Thai tax adviser and check with the Revenue Department.

Are You a Thai Tax Resident?

The key test is time in the country. Generally, if you spend 180 days or more in Thailand during a calendar year, you’re treated as a Thai tax resident. Residency is what brings foreign-income remittances into scope.

The 2024 Rule Change

For years, many residents relied on a practice of holding foreign income offshore and remitting it in a later year to keep it outside the Thai tax net.

From 1 January 2024, under Departmental Instruction Por.161/2566, that interpretation changed: foreign-source income remitted to Thailand by a tax resident can be taxable regardless of the year it was earned. In other words, the “wait a year” approach no longer reliably avoids tax.

A note on what’s coming: a further amendment has since been discussed that would exempt foreign income remitted in the same year it’s earned (or the following year) to encourage timely repatriation. Because this may or may not be in force when you read this, confirm the current position with the Revenue Department or a tax professional before making decisions.

Income vs. Savings vs. Capital

Not everything you transfer is “income.” Pre-existing savings and capital are generally treated differently from income earned abroad. Distinguishing them — and keeping evidence of when funds were earned and what they represent — is exactly where professional advice is valuable.

What Counts as “Remitting”?

Bringing value into Thailand can take several forms, all of which may count:

• An international bank transfer into a Thai account
• An ATM withdrawal in Thailand funded from an overseas account
• Card spending in Thailand funded from abroad

Treatment depends on timing and the evidence you can show, so keep good records.

Practical Transfer Tips

1. Compare the all-in cost — the headline fee plus the exchange-rate margin. Specialist transfer services often beat bank telegraphic transfers.
2. Mind the receiving-bank fee — some Thai banks charge a fee on incoming international transfers.
3. Keep transfer records — useful for tax, large-purchase proof (e.g. condo purchases need a foreign-currency transfer record), and visa financials.
4. Don’t move large sums without advice if you’re a tax resident and unsure of the treatment.

Frequently Asked Questions

Savings and capital are treated differently from income — get professional advice for your situation.

Who is a Thai tax resident?

Did Thailand change its foreign-income rules in 2024?

Yes. From 1 January 2024, under Departmental Instruction Por.161/2566, the long-standing practice that let residents avoid tax by remitting foreign income in a later year was changed, so remitted foreign-source income can be taxable regardless of the year earned. A further easing has since been discussed — confirm the current position before acting.
