You left Sri Lanka two years ago. You have been living and working in the UK. You spent only three weeks in Sri Lanka last year visiting family. You assume you are non-resident and have no Sri Lanka tax obligations on your UK salary. You are almost certainly wrong — and this could cost you significantly.
What Is the Deemed Resident Rule?
Under Section 79 of Sri Lanka’s Inland Revenue Act, if you were tax resident in Sri Lanka for two or more consecutive years of assessment before you left, you remain a deemed tax resident until you have been continuously absent from Sri Lanka for 365 days — visiting back no more than 30 days in total during that period.
This means the standard 183-day rule does not apply to you in your first year or two overseas. Even if you spend just 10 days in Sri Lanka, you are still taxed as a full resident — with worldwide income assessable by the IRD — until that 365-day continuous absence threshold is crossed.
A Real-World Example
Priya moved from Colombo to London in June 2024 for a permanent job. She visited Sri Lanka for Christmas 2024 (20 days) and again for a wedding in April 2025 (15 days). Her total Sri Lanka days for Y/A 2025/26: just 35 days in Sri Lanka during the year.
Priya assumes she is non-resident. But her Christmas and April visits totalled 35 days — exceeding the 30-day tolerance — which means her 365-day continuous absence clock reset in April 2025. She remains a deemed resident for Y/A 2025/26. Her UK salary is fully taxable in Sri Lanka. She also owes the 15% remittance tax on money she sent home to her parents.
The 30-Day Tolerance Rule
The Act does provide some relief. Short return visits totalling 30 days or less during your 365-day absence period are treated as if spent outside Sri Lanka — they do not break your continuous absence clock. So a brief two-week visit home is acceptable. But exceed 30 days total and the clock resets completely from the day you return to Sri Lanka.
The 2025 Contract Exemption: A New Exit Route
The Inland Revenue Amendment Act No. 2 of 2025 introduced an important exception. If you left Sri Lanka for overseas employment under a qualifying contract of at least one year with an employer that has no connection to a Sri Lankan employer of yours, you are treated as non-resident from the first day of the year of assessment in which you departed — regardless of the 2-year prior residency rule.
This is a significant benefit for Sri Lankans who left on employment contracts — but only if the contract meets the qualifying conditions. If you are unsure whether your contract qualifies, this is worth confirming with a tax advisor before your November 30 filing deadline.
