With over 120,000 Sri Lankans in the United Kingdom, the UK-Sri Lanka tax relationship is one of the most important for the diaspora to understand. The good news: the UK and Sri Lanka have a Double Taxation Agreement (DTA). The not-so-good news: claiming it correctly requires proper filing — and many Sri Lankans in the UK are missing out or unknowingly accumulating liabilities.
Are You Still a Sri Lanka Tax Resident?
If you moved to the UK recently, you may still be a deemed tax resident in Sri Lanka — even if you spent less than 183 days there last year. Sri Lanka’s 2-year deemed residency rule means that if you lived in Sri Lanka for two or more consecutive years before moving to the UK, you remain taxed as a Sri Lanka resident until you have been continuously absent for 365 days.
For Sri Lankans who moved to the UK on a Skilled Worker visa, Student visa, or UK Settled Status, this rule frequently applies in the first 1–2 years after departure. Use the Expat Tax Checker to confirm your exact status.
The UK-Sri Lanka Double Taxation Agreement
Sri Lanka and the United Kingdom have a comprehensive DTA. For Sri Lankans in the UK, this agreement means:
- UK income tax paid (via PAYE or Self Assessment) can be credited against your Sri Lanka tax liability on the same income
- For the 15% remittance tax: if you paid UK income tax at 20%, 40%, or 45% on earnings you remit to Sri Lanka, you are fully exempt — the UK tax already exceeds 15%
- Dividends, interest, and royalties between the two countries benefit from reduced withholding rates under the treaty
- You are protected from double taxation on employment income, business profits, and investment returns
Property in Sri Lanka: What UK-Based Owners Must Know
Many Sri Lankans in the UK own property back home — flats in Colombo, family homes, commercial premises. If those properties generate rental income, that income is subject to 14% withholding tax in Sri Lanka regardless of your residency status. You are also required to declare it in an IRD return.
GDP Consultants manages rental income tax filings for UK-based Sri Lankan property owners remotely — no need to appoint a local agent or make a trip to Colombo.
Filing Your Sri Lanka Tax Return from the UK
E-filing is mandatory for Sri Lanka income tax returns. Filing from the UK requires:
- Your IRD Taxpayer Identification Number (TIN) — obtainable online if you don’t have one
- Documentation of UK income (P60, P45, or Self Assessment tax return)
- Sri Lanka income details (rental statements, dividend certificates, bank statements)
- Evidence of UK tax paid to support DTA credit claims
The deadline is 30 November 2026 for the Y/A 2025/26 tax year (April 2025 – March 2026).
