How do I claim a tax refund from the IRD in Sri Lanka? (Y/A 2025/2026)

The short answer

If the tax you paid — through APIT, AIT/WHT, or quarterly instalments — exceeds your actual liability, the excess is a refundable amount the IRD must return to you under section 150 of the Inland Revenue Act. For years of assessment from 1 April 2025, a resident individual's claim of up to Rs. 180,000 must be paid within three months, before any audit. Alternatively you can elect a 60% early set-off against next year's tax via Cage 902A. You must claim within 30 months of the end of the year of assessment — for Y/A 2025/26 that means by 30 September 2028 — and if the IRD takes longer than six months to pay, it owes you interest at 0.5% per month under sections 158–159. Your refund position is established by declaring every APIT, AIT and instalment credit accurately in Schedule 9 of your return.

If more tax was deducted from your salary or bank interest than you actually owe, that money isn't gone — it's a refundable amount that the Inland Revenue Department (IRD) is legally required to return to you. Yet many Sri Lankan taxpayers never claim it, either because they don't realise they're owed anything or because the process seems opaque.

This guide explains exactly when a refund arises, what the law entitles you to, and the practical steps to get your money back.

The basic rule: pay more than you owe, and the excess is refundable

Section 150 of the Inland Revenue Act sets out a simple principle: where the tax you have paid exceeds the tax assessed or found to be payable, the difference is a refundable amount. The Commissioner-General must first set it off against anything else you owe the IRD, and then pay you the balance.

The most common reason people end up overpaying is that tax in Sri Lanka is largely collected in advance — through APIT deducted by your employer, AIT withheld by your bank, and quarterly self-assessment instalments — while your actual liability is only worked out once a year when you file your return. Whenever those advance collections overshoot your true liability, a refund arises.


Seven scenarios where you may be owed a refund

1. Your employer deducted too much APIT. This is by far the most common case. APIT tables deduct tax month by month on your remuneration, but your annual liability is computed after the personal relief of Rs. 1,800,000 and any other reliefs you're entitled to. If you worked only part of the year, changed jobs mid-year, received a bonus taxed under the lump-sum withholding rules, or qualified for reliefs your employer's tables couldn't capture (such as solar panel relief of up to Rs. 600,000), the total deducted often exceeds what you actually owe.

2. Banks or other payers withheld excess AIT/WHT. Advance Income Tax is withheld on interest, rent paid to certain landlords, and other payments. These withholdings are credits against your final liability — if your total income is modest, the amounts withheld can easily exceed the tax you owe.

3. You overpaid your quarterly instalments. Self-assessment and instalment payments are based on estimates. If your income came in lower than estimated, or you over-provided out of caution, the excess is refundable once the annual return is filed.

4. You are a senior citizen with AIT withheld on interest. Senior citizens who are not instalment payers have a specifically protected fast-track: qualifying refund claims must be paid within three months, without waiting for a tax audit.

5. You won an appeal or your assessment was revised downward. Tax paid under an assessment that is later reduced becomes refundable, and any interest you paid on an amount found not to have been payable must also be refunded to you.

6. Income you declared was later refunded to a customer. New under the Inland Revenue (Amendment) Act No. 11 of 2026: if you recognised income on a cash basis and later had to refund it because the underlying contract was cancelled or altered, you can reclaim the excess income tax paid on that refunded amount. You must apply within 30 months of the date the amount was refunded.

7. Double relief situations. Where the same income suffered both withholding and instalment payments, or foreign tax credits reduce your Sri Lankan liability below what was already collected, the combined credits can exceed your final tax.


How much can you get back quickly? The fast-track thresholds

Not every refund is treated the same. The law draws an important line based on the size of your claim:

For years of assessment commencing on or after 1 April 2025, 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. (For earlier years, the threshold was Rs. 60,000.)

Claims above the threshold can be subjected to an audit before payment — which in practice means longer waiting times and requests for supporting documents. Keep this in mind: if your credits are well documented, an audit is nothing to fear, but it does add time.


The 60% early set-off option

There's a lesser-known alternative to waiting for a cash refund. At your request, the IRD will set off 60% of your refundable amount against your next income tax liability — before any audit on the refund claim. On the individual income tax return, this is claimed through Cage 902A in Schedule 9 (Tax Credits).

For anyone with an ongoing tax liability — business owners paying quarterly instalments, for instance — this is often the fastest way to extract value from a refund, since it doesn't depend on the IRD's payment processing at all.


Don't miss the deadline: the 30-month time bar

This is the rule that catches people out. For years of assessment commencing on or after 1 April 2024, a refund claim must be made within 30 months of the last date of the relevant year of assessment.

In concrete terms: for the year of assessment 2025/26 (ending 31 March 2026), your refund claim must be lodged by 30 September 2028. Miss the window and the refund is lost, regardless of how clearly you overpaid. For years before 2024/25, the older rule applies — a claim within four years of the date of payment.


The IRD pays you interest on late refunds

Few taxpayers know this: if the IRD does not pay your refund within six months of your claim, it must pay you interest at 0.5% per month (computed monthly) from the date you filed the claim until the date the refund is paid. This is a statutory entitlement under sections 158 and 159 of the Act — not a discretionary gesture. Filing your claim promptly and keeping proof of the claim date matters, because that date starts the clock.


Step-by-step: how to actually claim your refund

Step 1 — File your annual return with the credits fully declared. Your refund position is established by your income tax return (the Asmt IIT series). Schedule 9 is where every credit lives:

Step 2 — Check your refundable balance. When your total credits (Cage 180 of the main return) exceed your total tax payable, the return shows an overpayment. That figure is your refundable amount.

Step 3 — Choose your route. Either lodge a refund claim through the IRD's RAMIS e-services portal (the claim date starts both the three-month fast-track clock and the interest clock), or elect the 60% set-off against next year's tax via Cage 902A.

Step 4 — Keep every certificate. APIT/T.10 certificates, AIT withholding confirmations from banks, and instalment payment receipts are what stand between you and a smooth refund — especially if your claim exceeds Rs. 180,000 and goes to audit. If a withholding agent's deduction doesn't appear in the IRD's system, your certificate is your evidence.

Step 5 — Follow up. If six months pass without payment, you are owed interest. Cite sections 158–159 of the Inland Revenue Act when following up with your regional office or through RAMIS.


Common mistakes that delay or sink refund claims


The bottom line

A tax refund from the IRD is not a favour — it's a statutory right with defined timelines, a fast-track for claims up to Rs. 180,000, a 60% early set-off option, and interest payable if the IRD is slow. What it demands from you is accurate credit reporting on your return, well-kept certificates, and a claim filed within 30 months.

TaxWise automatically computes your refundable balance from your APIT, AIT and instalment credits, flags claims that qualify for the three-month fast-track, and tracks your 30-month claim deadline.

Frequently asked questions

When does a tax refund arise in Sri Lanka?

A refund arises whenever the tax you have already paid — through APIT deducted by your employer, AIT/WHT withheld by your bank, or quarterly self-assessment instalments — exceeds your actual liability for the year. Because these are collected in advance while your real liability is only computed when you file, any overshoot becomes a refundable amount under section 150 of the Inland Revenue Act.

How quickly must the IRD pay my refund?

For years of assessment commencing on or after 1 April 2025, if you are a resident individual and your claim does not exceed Rs. 180,000, the Commissioner-General must pay it within three months of your claim, before any tax audit. Larger claims can be audited before payment, which takes longer. Senior citizens who are not instalment payers have a protected three-month fast-track on qualifying interest-AIT refunds.

What is the 60% early set-off option?

Instead of waiting for a cash refund, you can ask the IRD to set off 60% of your refundable amount against your next income tax liability — before any audit on the refund claim. On the return this is claimed through Cage 902A in Schedule 9. For anyone with an ongoing liability, such as a business owner paying quarterly instalments, it is often the fastest way to realise a refund.

What is the deadline to claim a tax refund?

For years of assessment commencing on or after 1 April 2024, you must claim within 30 months of the last date of the relevant year of assessment. For Y/A 2025/26, which ends on 31 March 2026, the claim must be lodged by 30 September 2028. Miss the window and the refund is lost. For earlier years, the older rule applies — a claim within four years of the date of payment.

Does the IRD pay interest if my refund is late?

Yes. If the IRD does not pay your refund within six months of your claim, it must pay interest at 0.5% per month, computed monthly, from the date you filed the claim until the refund is paid. This is a statutory entitlement under sections 158 and 159 of the Act, not discretionary — which is why keeping proof of your claim date matters.

Can I get a refund on final withholding taxes?

No. Some withholding — such as the 15% on resident-company dividends — is a final tax, not an advance, so it cannot generate a refund. Refund credits arise only on advance-type deductions like APIT on employment, AIT on interest, and instalment payments. Claiming a credit for a final tax is a common mistake that delays or sinks a claim.
