Guide for Sri Lankans in the UK: Tax residency, filing obligations, and e-filing Y/A 2025/26 on taxcalculator.lk. Learn how to file your Sri Lanka tax return from overseas.
If you are a Sri Lankan living in the United Kingdom—whether as a citizen or non-citizen—you need to understand your Sri Lankan tax filing obligations for the year of assessment (Y/A) 2025/2026. Your tax liability in Sri Lanka depends on whether you are a tax resident or a non-resident, and it is determined primarily by the 183-day physical presence rule.
This comprehensive guide will help you navigate the rules, understand filing requirements, and e-file your Sri Lanka tax return from overseas.
Understanding Sri Lankan Tax Residency for Expats
Tax residency is the cornerstone for determining your Sri Lankan income tax obligations.
The 183-Day Rule
You are considered a tax resident if you are physically present in Sri Lanka for 183 days or more during any 12-month period within the year from April 1, 2025, to March 31, 2026. Residents are subject to tax on their worldwide income, including salaries, dividends, and rental income from abroad.
Non-residents—including most Sri Lankan expats in the UK—are generally taxed only on Sri Lankan-source income, such as:
- Rental income from property in Sri Lanka
- Bank interest earned in Sri Lanka
Key Note: From April 2025, a 15% tax applies to foreign service income for residents working abroad but maintaining residency under the 183-day rule.
Citizenship Considerations
- Sri Lankan citizens abroad: Typically non-residents unless meeting the 183-day threshold or other exceptions (e.g., government employees abroad).
- Loss of citizenship: Does not change tax obligations if you have Sri Lankan-source income. Former residents follow non-resident rules.
Filing Liability for Y/A 2025/2026
Whether you are a resident or non-resident determines your filing obligation.
| Status | Tax Scope | Key Thresholds |
|---|---|---|
| Resident (183+ days in SL) | Worldwide income | LKR 1,800,000 annual; personal relief LKR 1,200,000 |
| Non-Resident (citizen or non-citizen) | Sri Lankan-source income only | Any taxable local income (e.g., rent, bank interest) |
Who must file:
- Residents earning LKR 150,000+ per month (LKR 1.8M annually)
- Non-residents with Sri Lankan-source income, including rental or interest income
Optional but recommended:
Even if non-residents have no Sri Lankan-source income, filing may be advisable to avoid future audits, secure TIN updates, or meet investment/property reporting requirements.
