Can the IRD prosecute you for not filing a tax return? (2026)

On 10 July 2026, the Inland Revenue Department issued a public notice (SEC/PN/IT/2026-04) that deserves more attention than it's getting. Under the Inland Revenue (Amendment) Act, No. 11 of 2026 — in force since 3 June 2026 — the Commissioner General of Inland Revenue can now initiate criminal prosecution against individuals and businesses who deliberately fail to meet their income tax obligations.

That's a different order of consequence from the penalties and interest most people associate with late filing — this ends before a Magistrate.

If you've been putting off registering, or you have a tax file you've quietly ignored for a couple of years, this is the notice that changes the calculation. Here's what it says, in plain language.

What changed

The Amendment Act amends the Inland Revenue Act, No. 24 of 2017. Until now, the IRD's main tools against non-filers were financial: penalties and interest on unpaid tax. The new provisions add a criminal track for three specific failures:

• Failure to register with the Commissioner General of Inland Revenue when you're required to.
• Failure to file income tax returns.
• Failure to file annual statements — including Withholding Tax (WHT) and Advance Personal Income Tax (APIT) returns.

That third one matters for employers and anyone deducting tax at source, not just individual taxpayers. If your business deducts APIT from staff salaries but hasn't been filing the annual statements, you're inside the scope of this notice.

The 30-day window

The IRD has been explicit that prosecution is a last resort, and there's a mandatory process before anything reaches a courtroom.

First, you get a formal written notice stating the IRD's intention to prosecute. From the date of that notice, you have a strict 30-day grace period to fix the non-compliance — register, file the outstanding returns, submit the missing statements.

Comply within those 30 days and the matter ends there.

Fail to, and it becomes an offence. Conviction follows a summary trial before a Magistrate, and the penalties are real: a fine of up to Rs. 400,000, imprisonment for up to six months, or both.

Thirty days sounds like enough time. It isn't, if you're starting from a shoebox of receipts and three years of bank statements. Anyone who has actually prepared a return knows the work is in the reconciliation — pulling together income from salary, fees, rent and interest, matching it against bank records, and getting it into the IRD's schedule format. That's weeks of evenings for most people doing it manually. Starting only when a prosecution notice arrives is the worst possible time to begin.

Who the IRD says it's going after

The notice is unusually direct about targeting. The IRD states the provisions are aimed at deliberate evaders — people and businesses that intentionally fail to register, don't submit returns, or conceal income despite being liable for significant tax. Its words: "the law is designed to target deliberate tax evaders, not cooperative citizens."

Two groups get explicit comfort:

If you have no tax liability and only hold a TIN, the IRD says you will not face these proceedings at this time. Registering for a Taxpayer Identification Number alone doesn't put you in the firing line.

If the IRD opened a tax file in your name but you have no actual liability, you can ask your regional IRD office to close the file. The notice says formal instructions have already gone out to tax officials to handle these closure requests smoothly. If that's your situation, make the request — a dormant open file is exactly the kind of loose end you don't want under a stricter enforcement regime.

Everyone else — anyone with an actual income tax liability — is "strongly advised to ensure timely compliance with the law to avoid enforcement actions." That's about as clear as IRD language gets.

What you should do now

If you're already registered and filing on time, nothing changes. Keep your records current and file before the deadline — the final return for Y/A 2025/2026 is due 30 November 2026.

If you have income above the tax-free threshold and you've never registered, register before the IRD writes to you. Voluntary compliance and a prosecution notice are very different starting positions.

If you have unfiled returns from past years, the message in this notice is that the window for quietly ignoring them is closing. The IRD's own advice is that "most issues can be easily resolved through early dialogue" — early being the operative word.

And if you get any written correspondence from the IRD, don't let it sit. Under the new regime, a letter you ignore can be the first step in a 30-day countdown.

The honest takeaway

Sri Lanka's tax administration is shifting from persuasion to enforcement, and it's doing it in stages: mandatory e-filing came first, and criminal prosecution for non-filers is now on the books. The good news buried in the notice is that compliant taxpayers have nothing new to worry about, and even non-compliant ones get a written warning and a month to put things right.

The practical problem is that "putting things right" means having your numbers ready — and that's the part most people underestimate.

That's where TaxWise comes in. You enter your income and expenses, upload your bank statements, and TaxWise reconciles the transactions and generates your IRD schedules for Y/A 2025/2026 — in English or Sinhala. Whether you're filing on time or catching up before a deadline you can't afford to miss, the fastest route from "haven't started" to "ready to file" is not a spreadsheet.
