Do You Need to File a Nil Return in Sri Lanka?

"I don't owe any tax, so I don't need to file."

We hear this on almost every customer call. Usually said with total confidence. Often by someone who is about to leave money at the Inland Revenue Department and never think about it again.

So let's sort it out. What happens if you owe nothing? Do you file? And what's this Nil Return everyone keeps mentioning?

First, the bit everyone gets wrong

Owing nothing and filing nothing are two different things.

Tax is what you pay. A return is what you tell IRD. You can genuinely owe zero rupees and still have a return to submit.

Think of it like attendance. Showing up and paying the fee are separate steps. Skipping the fee because you're exempt doesn't mean you skip the register.

Okay but do I actually have to?

Here's where most articles pick a side and hope you don't check. We'll give you the real answer, which is slightly awkward.

What the law says. Section 94 of the Inland Revenue Act lists people who don't have to file. Right at the top: a resident individual with no tax payable for the year. Salaried employees whose employer deducts APIT correctly are on the list too.

So if your income is under Rs. 1.8m and nothing is left to tax, the Act does not require you to file.

What happens in practice. IRD opens income tax files. In a notice published in June 2026, IRD said that once the Commissioner-General opens a file for you, you must keep filing returns until that file is officially closed.

Most tax practitioners in Sri Lanka will tell you flatly that you have to file. They're not making it up. They're describing what happens to real clients, where a file exists, a notice is easy for IRD to send, and arguing about it costs more than filing would have.

The practical answer. If IRD has a file on you, file. If they don't, you're not legally required to, but there are good reasons to anyway. We'll get to those, and one of them involves money coming back to you.

What a Nil Return actually is

A Nil Return is IRD's own term. It's not a special lighter form. It's your normal return where the tax at the bottom comes out at zero.

It applies when you have no taxable income, which is not the same as no income at all. Everyone gets a personal relief of Rs. 1.8m per year. Earn Rs. 1.4m and your taxable income is zero. You had plenty of income. You just have nothing to tax.

One thing catches people out. A Nil Return is not "nothing to report."

You still declare your income from every source. And you attach a Statement of Assets and Liabilities, which asks for the value of everything you own as at the end of the year. Property, vehicles, bank deposits, shares, cash in hand, loans you've given out, gold and jewellery. In Sri Lanka and outside it. Plus what you bought, received as a gift, or sold during the year.

None of it changes your tax. IRD wants the picture.

So budget a bit of time for it. It's not a five-minute job if you own things.

The part nobody tells you

Now the good bit.

Money has probably already been taken from you this year, and you may be entitled to get it back.

Your bank takes 10% off your fixed deposit and savings interest before it reaches you. If you invoice Sri Lankan clients, they take 5% off payments over Rs. 100,000 a month.

Here's the thing about those deductions. They're advance payments, not your final tax bill.

Your bank has no idea you have Rs. 1.8m of relief coming. It doesn't know your total income. It just takes 10% off every rupee of interest and sends it in. Your client does the same with 5% of your invoice.

Your return is where the real number gets worked out. Relief applied, income added up, actual tax calculated. Then everything already deducted comes off that.

If more was taken than you owed, the difference comes back to you.

What that looks like

Take a consultant billing Rs. 200,000 a month to a local company.

• Income for the year: Rs. 2,400,000
• Deducted at 5% along the way: Rs. 120,000
• Less the Rs. 1.8m relief: Rs. 600,000 taxable
• Tax on that, at the first band of 6%: Rs. 36,000
• Refund: Rs. 84,000

He earns well over the relief and still gets most of it back. The 5% was charged on everything he billed. His real tax was charged on a quarter of it, after relief. You can check the bands against your own income if you want to see where you land.

Now take someone earning Rs. 1.2m freelancing, with a bit of FD interest. Their tax is zero. Every rupee deducted comes back.

For claims up to Rs. 180,000, IRD is required to process the refund within three months, before any audit. Most individual claims fall well under that.

None of this happens automatically. IRD will not calculate your relief and send you a cheque. A return is the only way to ask.

When filing stops being optional

Plenty of people who think they're exempt aren't. Check yourself against this list.

You have savings or FDs. The salaried exemption only holds if your interest income for the year stays under Rs. 5,000. That's roughly Rs. 60,000 sitting in an account. Cross it and you're required to file. This came in with Amendment Act No. 11 of 2026 and almost nobody knows about it.

You earn anything outside your salary. Freelance work, consulting, rent from a property, a side business. Any of it puts you outside the salaried exemption. If any of it is paid from abroad in foreign currency, a different rate ceiling applies.

You changed jobs during the year, or held two at once. Both employers likely applied the full relief to your salary. Which means between them they gave you the allowance twice, and you may owe money without realising.

You have a business or you're registered for income tax with a file open. Then you file, every year, until that file is closed.

What it costs to skip it

If you were required to file and you didn't, the penalty is not a percentage of your tax bill. It's a flat amount.

Section 178 sets it at Rs. 50,000, plus another Rs. 10,000 for every month it stays unfiled, capped at Rs. 400,000 per return.

Read that again with zero tax in mind. Five percent of nothing is nothing, so the flat figure applies instead. You can owe no tax at all and still be looking at Rs. 50,000.

That only applies where filing was actually required. But given how many people think they're exempt and aren't, it's not a comfortable thing to be wrong about.

So what should you do

If you're clearly required to file, you already know. Get it in before 30 November.

If you're not sure, assume you might be. The list above catches more people than you'd expect, and a savings account is usually all it takes. Answering a few questions is faster than reading the Act.

If you're genuinely exempt, file anyway if anything was deducted from your interest or your invoices. That's your money and this is the only route back to it. Even with nothing to reclaim, a few years of filings behind you is worth having when a bank, an embassy, or IRD asks what you've been earning.

The version of this that costs you money is the one where you assume you're fine and never check.
