From 1 April 2025, Sri Lanka introduced a 15% final tax on foreign-sourced income remitted to Sri Lanka through the banking system. Most overseas Sri Lankans sending money home have no idea this rule exists — and are now unknowingly accumulating a tax liability with the IRD.

What Exactly Is the 15% Remittance Tax?

Under amendments to the Inland Revenue Act effective from 1 April 2025, any income you earned overseas that is remitted to Sri Lanka via the banking system is subject to a 15% final withholding tax. This applies to both resident and non-resident Sri Lankans.

The key word is remitted via the banking system. This covers bank transfers, SWIFT payments, and electronic transfers through Sri Lankan banks. Cash carried in your pocket when you visit does not trigger this rule — but any bank-to-bank transfer does.

Who Is Exempt?

If you already paid 15% or more tax on that income in your country of residence, you are exempt from further Sri Lankan tax on that remittance. You simply need documentation proving the overseas tax was paid.

If you paid less than 15% overseas — or paid no tax at all on that income (for example, earnings below your home country’s tax threshold) — you must pay the difference to the IRD to bring the effective rate to 15%.

The Double Taxation Agreement (DTA) Protection

If your country of residence has a Double Taxation Agreement (DTA) with Sri Lanka, you can claim a foreign tax credit — offsetting the overseas tax paid against your 15% Sri Lanka liability. Sri Lanka has DTAs with over 46 countries including the UK, Australia, Canada, UAE, India, Singapore, Germany, and France.

Important: if you paid more than 15% abroad, your DTA credit cannot be refunded or carried forward. You simply owe nothing further in Sri Lanka. If you paid less, you pay only the difference.

What About Regular Family Remittances?

This is where many overseas Sri Lankans get confused. Not every bank transfer to Sri Lanka is subject to the 15% rule. The tax applies specifically to income-sourced foreign funds remitted via banking channels — not to savings already held or non-income transfers. However, demonstrating that a remittance is not income-sourced requires documentation, and in practice the banking system may withhold tax on transfers unless you have the right paperwork in place.
