Questions and answers
Personal tax: common questions
General information only. Each answer names the section of the law it comes from. Check ird.gov.lk for anything that may have changed.
What does Numerela do, and what do I do?
Numerela provides assistance only. We work out your return from the information and documents you give us, and a person on our team reviews it. Our agent logs in to IRD e-Services with your TIN and IRD PIN, enters your return, and sends you a summary of every box. You check it and approve it with a one-time code we send you. We submit only after you approve. You remain responsible for your return and for any tax you owe. We recommend changing your PIN after filing; it is your choice.
Who needs a TIN?
A person who has to file a return of income, and is not already registered, must register with the Commissioner-General of Inland Revenue (Inland Revenue Act s.102(1)). The Minister, with the consent of the Commissioner-General, can name more classes of people who must register (s.102(3)). Gazette Extraordinary No. 2334/21 of 31 May 2023 does this, and it includes resident individuals aged 18 or more from 1 January 2024. Check ird.gov.lk for the current list.

Is a TIN the same as filing a return?
No. A TIN does not by itself create a duty to file a return. The duty to file comes from sections 93 and 94 of the Act.

Who has to file, and by when?
A return is due for each year of assessment (1 April to 31 March), not later than eight months after the year ends (IRA s.93(1)). For the year of assessment 2025/26 that is Monday 30 November 2026. A return may not be required if you have no tax to pay (IRA s.94). IRD can still serve a notice requiring a return (s.94(2)). IRD Notice SEC/PN/IT/2026/02, section 12, says an individual whose only income is employment income fully covered by Advance Personal Income Tax (with no instalments or final payment due) need not keep an income tax file or file returns, but if the Commissioner-General opens a file for such an individual, they must keep filing until it is officially closed. Numerela practice, not law: if a date falls on a weekend or public holiday, pay or file by the last working day before it.

What is the personal relief?
For each year of assessment starting on or after 1 April 2025, the personal relief is Rs 1,800,000. Whether any tax is payable depends on all of your income and tax already deducted.

When do instalments and the final payment fall due?
Instalments of income tax fall due on 15 August, 15 November and 15 February in the year of assessment, and on 15 May after it. The final payment falls due six months after the year ends. For the year of assessment 2025/26 the final payment date was 30 September 2026. Not everyone pays instalments: it depends on your income and on tax already deducted. If tax for 2025/26 is still unpaid, pay it as soon as you can. IRD's notice of 26 September 2026 says interest and penalty apply to late payment, and the Act sets a penalty of 20% of the tax not paid within fourteen days of the due date (s.179(1)).

What happens if I file late?
The Act sets a penalty for a late return: the greater of 5% of the tax owing plus 1% for each month or part of a month, and Rs 50,000 plus Rs 10,000 for each month or part of a month. The penalty is limited to Rs 400,000 for a return (s.178). If a person fails to file a return of income, the Commissioner-General must first serve a written notice giving thirty days to comply. A person who then fails, without reasonable cause, to comply can be convicted and fined up to Rs 400,000, or imprisoned for up to six months, or both (s.185A, added by Act No. 11 of 2026). The Act, not this guide, governs.

Where and how is tax paid?
Tax is paid to the Inland Revenue Department itself, through its Online Tax Payment Platform (OTPP) in your own bank's online portal, or at a Bank of Ceylon branch. For a bank branch payment you need a DIN (Document Identification Number), which you can get from IRD's e-Services site. The tax type code for individual income tax is 05, and the payment period code for the 2025/26 final payment is 25260. Check ird.gov.lk for the current steps.
