How to Claim a Tax Refund from the IRD in Sri Lanka

If you are a salaried employee or an investor in Sri Lanka, there is a real chance the Inland Revenue Department is holding money that belongs to you. Tax gets deducted from your salary and your bank interest before it ever reaches you. Sometimes more comes off than you actually owe. When that happens, you are owed a refund, and there is a defined process to get it back.

Most people never claim what they are owed, simply because they do not know they overpaid. The tax came out automatically, so it feels settled. It is not. This guide walks through how to claim a tax refund in Sri Lanka: how to spot an overpayment, the exact process, how long it takes, and the deadline you cannot afford to miss.

How do I know if the IRD owes me a refund?

You are owed a refund whenever the tax already collected from you during the year is more than your final tax bill for that year. The tax collected from you in advance comes in three main forms, and each one counts as a credit toward your final liability.

• APIT (Advance Personal Income Tax), deducted by your employer from your salary.
• WHT / AIT (Advance Income Tax), deducted by your bank on interest, or by a client on professional fees.
• Quarterly instalments you paid yourself if you are a self-assessment taxpayer.

Here is the part that matters. For a resident individual, none of these are the end of the story. They are all creditable, meaning they get subtracted from your final tax, and if they add up to more than you owe, you get the difference back.

What causes an overpayment of tax in Sri Lanka?

Overpayments are common, and they usually happen quietly. These are the situations where you are most likely owed money.

Your bank withheld tax you did not really owe. With effect from April 1, 2025, banks deduct Advance Income Tax at 10% on the interest they pay you. For a resident individual, that 10% is not final. Your interest is added to your other income and taxed at the normal progressive rates after the Rs. 1,800,000 personal relief. If your total income sits below that relief, or your effective rate on that interest is below 10%, the bank took too much.

Your employer over-deducted APIT. Your employer calculates APIT on your salary, but they do not always know about reliefs or deductions you are entitled to. If you had reliefs your employer did not apply, the tax taken from your pay can exceed what you actually owe once everything is accounted for on your return.

You overpaid your quarterly instalments. Self-assessment taxpayers estimate their income and pay in four instalments. If your income fell short of the estimate, or a big invoice never got paid, you may have paid more across the year than your final liability. Getting the estimate right in the first place is easier with our guide on estimating quarterly tax on irregular income.

Let's put a number on it.

Mr. Perera is retired. His only income for the year is Rs. 1,500,000 in bank interest. Through the year, his bank deducted Advance Income Tax at 10%, which comes to Rs. 150,000.

But look at his actual liability. His total income of Rs. 1,500,000 is below the Rs. 1,800,000 personal relief every resident individual receives. So his taxable income is zero, and his final tax for the year is Rs. 0.

He paid Rs. 150,000. He owed nothing. The IRD is holding Rs. 150,000 that belongs to him. The only way he gets it back is by claiming it.

How do I actually claim my tax refund? (the process)

There is no separate "refund application form" for the standard case. The claim is built into your annual tax return. Here is the sequence.

1. File your Return of Income for the year. Declare all your income, from every source, for the full year of assessment. If you have never done this, our walkthrough on filing your first tax return covers the mechanics.
2. Claim every credit you are entitled to. On the return, enter the APIT your employer deducted, the WHT your bank or clients deducted, and any quarterly instalments you paid. Under Section 89, you are entitled to a credit equal to the tax withheld from you. Under Section 90(5), you are entitled to a credit for the instalments you paid.
3. The return computes your overpayment. When your total credits exceed your final tax for the year, that excess is a "refundable amount" under Section 150(1) of the Inland Revenue Act.
4. The Commissioner-General processes the refund. Once your refundable amount is confirmed, the IRD works through it in a set order, which we cover in the offset section below.

How long does the IRD take to pay a refund?

It depends on the size of your claim. The law now sets a hard timeline for smaller refunds so ordinary taxpayers are not left waiting.

For the Year of Assessment 2025/2026 and onwards, if you are a resident individual and your refund claim does not exceed Rs. 180,000, the Commissioner-General must pay it within three months of your claim, before any tax audit is carried out.

Senior citizens get the same fast track. If a senior citizen is not an instalment payer and their claim does not exceed Rs. 180,000 for the year, or Rs. 45,000 for any quarter, the refund must also be paid within three months, before audit. That is exactly the position Mr. Perera from our example is in, so his Rs. 150,000 should reach him within three months. If your income is mainly bank interest, our guide on tax on senior citizens' interest income is worth a read.

Larger claims, above Rs. 180,000, can take longer, because the IRD may audit the claim before releasing the money.

Is there a deadline to claim my refund?

Yes, and this is the one that catches people out. You do not have forever.

For a year of assessment beginning on or after April 1, 2024, you must apply for the refund within 30 months of the last date of that year of assessment. The year of assessment 2025/2026 ends on March 31, 2026, so the clock for that year runs out at the end of September 2028.

There is a special case worth knowing. If you had to refund income you previously reported under cash-basis accounting, for example a cancelled contract you had already been paid for and declared, you have 30 months from the date you refunded that income to claim the corresponding tax back.

Will the IRD pay me interest on a delayed refund?

Yes. If the Department sits on your money, the law makes them compensate you. Under Section 158, interest accrues on a refundable amount at 0.5% per month, or part of a month.

There is a grace period. No interest is payable if the refund reaches you within six months of your claim. Interest only starts to matter once the delay stretches past that point. So the interest rule is really a backstop against long delays, not something you should count on for a refund paid on the normal timeline.

What if my refund is offset against other tax I owe?

Your refund does not always land in your bank account as cash. The Commissioner-General is required to work through it in a fixed order under Section 150.

1. Arrears first. Any outstanding tax, interest, or penalties you owe are cleared using your refundable amount before anything is paid out.
2. Future instalments next. Unless you object, the remaining amount is applied against the advance payments you owe in the following six months.
3. Optional 60% set-off. On your request, the IRD can set off 60% of the refundable amount against your future income tax, before completing a tax audit on the claim. This is a way to get value from the refund faster while the audit runs.
4. Cash for the balance. Whatever is left after all of the above is paid directly to you.

So if you owe the IRD for a previous year, do not expect the full refund in cash. It settles the old debt first, which is usually the outcome you want anyway.

The bottom line

A tax refund in Sri Lanka is not a favour the IRD does for you. It is money you are legally owed when the tax collected in advance exceeds your real liability. The three things to remember are simple. Your APIT and your bank interest WHT are creditable, not final, so they can come back to you. The claim runs through your annual Return of Income, not a separate form. And you have 30 months from the end of the year of assessment to lodge it, after which the money is lost for good.

If you have only ever let tax come off automatically and never filed a return, there is a decent chance you have been quietly overpaying for years. Start with the current year, file the return, claim your credits, and see what the numbers say. You might be pleasantly surprised.
