Key takeaways
- You are a Sri Lankan tax resident for a year of assessment (1 April – 31 March) if you are present in Sri Lanka for 183 days or more in any 12-month period that starts or ends in that year; residents are taxed on worldwide income, non-residents only on Sri Lankan-source income.
- From the year of assessment starting 1 April 2025, resident individuals (and Sri Lankan citizens even if non-resident) receive a personal relief of LKR 1,800,000 before progressive rates apply.
- A tax residency certificate for treaty purposes is issued by the Inland Revenue Department (IRD) on application, usually after you hold a Taxpayer Identification Number (TIN) and have filed returns.

Sri Lanka's residence rules are simpler than most: a clear day-count test, worldwide taxation for residents, and a generous personal relief that was raised in 2025. This guide explains how residence is determined, what it means for your income, how to obtain a tax residency certificate and what location-independent professionals should plan for.

Who is a Sri Lankan tax resident?
Under the Inland Revenue Act No. 24 of 2017, an individual is resident for a year of assessment if they:
- are present in Sri Lanka for 183 days or more in any 12-month period that begins or ends in that year of assessment; or
- are a Sri Lankan citizen serving abroad as a government official; or
- were resident in the previous year and remain present for at least one day in the current year, under the carry-over rule in section 69 of the Inland Revenue Act; check the exact wording with an adviser if you leave mid-year.
Partial days count as days of presence, so keep a travel log: entry/exit stamps and flight records are what the IRD will rely on.
Residence and treaties
If you are also resident in another country (for example the UK, India or Australia), the double tax treaty tie-breaker applies: permanent home, then centre of vital interests, then habitual abode, then nationality. Sri Lanka has a network of more than 40 double tax treaties.
What does Sri Lankan residence mean for your income?
- Residents pay tax on worldwide income: employment, business and professional income, investment income and certain gains.
- Non-residents pay tax only on income arising in Sri Lanka, such as work performed in Sri Lanka or Sri Lankan rental income.
- Personal relief: from year of assessment 2025/26, the first LKR 1,800,000 of taxable income is relieved for resident individuals and for Sri Lankan citizens (resident or not). The relief cannot be set against gains from realising investment assets.
- Employment income is subject to the Advance Personal Income Tax (APIT) withholding by employers.
- Foreign-source income of residents is within scope; treaty credit or exemption may prevent double taxation.
Example: A Sri Lankan citizen working remotely from Colombo for a Singapore company, earning LKR 6,000,000 in 2025/26, is resident (over 183 days present) and taxable on that salary in Sri Lanka. The first LKR 1,800,000 is relieved; because the income comes from services provided to a foreign payer and is remitted through a Sri Lankan bank, the remaining LKR 4,200,000 is taxed at a maximum rate of 15% (the former exemption for service-export income was abolished on 1 April 2025).
How to get a tax residency certificate in Sri Lanka
A certificate of residence is needed to claim reduced withholding tax under a treaty, or to prove to a foreign bank or tax authority that you are Sri Lankan resident.
- Register for a TIN with the IRD (online through the RAMIS portal).
- File your income tax returns for the relevant years (returns are due by 30 November after the end of the year of assessment).
- Apply to the IRD for a certificate of residence, stating the year, the treaty country and the purpose (e.g. dividends, services, pension).
- Provide evidence of presence: passport pages, travel history, local address, employment or business records.
- Submit the certificate to the foreign payer or tax authority, often together with their own treaty form.
Becoming or ceasing to be resident: practical points
- Arriving mid-year: you become resident once your presence reaches 183 days in a 12-month window; plan large foreign receipts (bonuses, sale of foreign shares) with this timing in mind.
- Leaving Sri Lanka: once you are no longer present for 183 days in a 12-month period, your worldwide income falls out of scope; Sri Lankan-source income stays taxable. Settle outstanding returns before departure.
- Location-independent professionals and freelancers: foreign clients do not take you out of scope if you are resident. Register for a TIN, keep invoices and, if you work through a foreign company, check whether your activity in Sri Lanka creates a permanent establishment for that company.
Frequently asked questions
How many days do I need to be in Sri Lanka to be a tax resident?
183 days or more in any 12-month period that starts or ends in the year of assessment (1 April – 31 March). The test counts physical presence, so partial days usually count. Keep entry and exit records to prove your status either way.
Are foreigners taxed on worldwide income in Sri Lanka?
Yes, if they are resident. Residence depends on presence, not nationality. A foreigner present for 183 days or more in a 12-month period is taxed on worldwide income; otherwise only Sri Lankan-source income is taxable.
How do I get a tax residency certificate in Sri Lanka?
Register for a TIN, file your returns and apply to the Inland Revenue Department for a certificate of residence, specifying the year and treaty country. Attach evidence of presence and income. The certificate is then sent to the foreign payer or tax authority.
What is the tax-free allowance in Sri Lanka?
From 1 April 2025 the personal relief is LKR 1,800,000 per year of assessment for resident individuals and Sri Lankan citizens, before the progressive rates apply. It cannot be used against gains on investment assets.
Do I need to file a tax return if my income is below the relief?
Generally a return is required if you have taxable income above the relief or are registered for a TIN. Check your situation with the IRD, especially if you receive foreign income or treaty-related payments.
