One of the biggest fears of overseas Sri Lankans who earn or invest in Sri Lanka is: “Will I be taxed twice on the same income?”
The good news is that Sri Lanka has signed Double Taxation Agreements (DTAs) with over 40 countries to prevent exactly this. If you understand how DTAs work, you can legally avoid paying tax twice and potentially save significant money.
What is a Double Taxation Agreement (DTA)?
A DTA is a treaty between two countries that determines:
- Which country gets to tax specific types of income
- How tax credits work between the two countries
- Reduced withholding tax rates on dividends, interest, and royalties
The goal is simple: you should not be taxed on the same income by both countries.

How DTAs Work in Practice
Example 1: Rental Income (Sri Lankan in the UK)
You live in the UK and rent out your house in Sri Lanka for Rs. 3,000,000/year.
- Sri Lanka taxes the rental income (property is in SL)
- UK also requires you to declare worldwide income including SL rental income
DTA solution: You pay tax in Sri Lanka first. When you file your UK tax return, you claim a Foreign Tax Credit for the tax already paid in Sri Lanka. The UK will reduce your UK tax by the amount paid in Sri Lanka — so you don’t pay double.
Example 2: Bank Interest (Sri Lankan in Australia)
You have an FD in a Sri Lankan bank earning Rs. 500,000 in interest. The bank deducts 10% AIT (Rs. 50,000).
- Sri Lanka deducts 10% at source
- Australia taxes your worldwide income
DTA solution: When filing your Australian tax return, declare the Sri Lankan interest income and claim the Rs. 50,000 (converted to AUD) as a foreign tax offset.
Example 3: Dividends (Sri Lankan in Canada)
You receive dividends from a Sri Lankan company. Sri Lanka deducts 14% WHT.
DTA solution: Under the Sri Lanka-Canada DTA, the WHT rate may be reduced. You can claim the WHT paid in Sri Lanka as a foreign tax credit on your Canadian return.
Reduced Withholding Tax Rates Under DTAs
DTAs often reduce the standard withholding tax rates on cross-border payments:
| Income Type | Standard SL Rate | DTA Reduced Rate (varies by country) |
|---|---|---|
| Dividends | 14% | 7.5% – 15% |
| Interest | 5% – 14% | 0% – 10% |
| Royalties | 14% | 0% – 10% |
Note: The exact reduced rates depend on the specific DTA between Sri Lanka and your country. Always check the applicable treaty.
How to Claim DTA Benefits
From the Sri Lanka Side:
- File your Sri Lankan tax return via RAMIS
- Include details of income taxed in both countries
- Claim treaty benefits using the forms available on the IRD portal
From the Foreign Country Side:
- Declare your Sri Lankan income on your local tax return
- Claim a Foreign Tax Credit for taxes paid to Sri Lanka
- Keep proof of Sri Lankan tax payments (e.g., WHT certificates, AIT deduction statements)
Common Mistakes to Avoid
- Not declaring Sri Lankan income in your country of residence — this can lead to penalties
- Not claiming foreign tax credits — you lose money by paying double
- Assuming Gulf = no obligation — if you have SL-sourced income, you may still need to file
- Ignoring DTA benefits — many people pay the standard WHT rate without claiming the reduced treaty rate
