What Happens If You Don't File Your KRA Returns? Penalties, Interest and How to Fix It

Miss KRA's filing deadline in Kenya and a penalty lands on your iTax ledger straight away: KES 2,000, or 5% of the tax you owe if that works out higher. Nothing more dramatic happens on day one.

Leave it longer, though, and it gets expensive fast. The unpaid amount earns interest every month, KRA can estimate your tax itself and come after that figure, and you won't get a Tax Compliance Certificate until your returns are filed and your taxes paid. Below: exactly what you'll owe, what KRA can do next, and how to clear it, checked against KRA's own rules in November 2026.

Quick facts: what you owe for not filing

How much is the KRA penalty for filing late?

For an individual's annual income tax return, the Tax Procedures Act sets the penalty at 5% of the tax you owe, or KES 2,000, whichever is higher. Most salaried people with simple returns end up paying the flat KES 2,000, because 5% of their tax bill rarely crosses that line.

Had no income to declare and still missed the deadline? You're not off the hook. A late nil return still attracts the flat KES 2,000, since 5% of nothing is nothing. Every PIN holder with no tax to pay still has to file a nil return by the same deadline, not skip filing altogether.

Businesses and VAT-registered taxpayers face steeper numbers under the same law: 5% of the tax due or KES 20,000 for most non-individual filers, and 5% or KES 10,000 for VAT and excise returns. Budget for the higher figure if that's you.

The 2025 return, covering income earned in 2025, was due on 30 June 2026. That date has passed, so if you still haven't filed it, this penalty is already on your account whether or not you've checked iTax.

Late payment penalty and interest: the part people miss

Filing late and paying late are two different failures, and KRA charges for both. Even if you file today, if the tax itself is still unpaid, a separate late payment penalty of 5% of the tax due kicks in, on top of the filing penalty.

Then there's interest: 1% of the unpaid tax for every month, or part of a month, that it stays outstanding. It's simple interest, not compounded, but it still climbs the longer you leave it.

Say you owed KES 30,000 in tax on your 2025 return, filed four months late, and still haven't paid:

That KES 4,700 keeps growing every extra month you wait, because the interest clock doesn't stop.

Can KRA just calculate the tax for you?

Yes. If you don't file, KRA can issue what the law calls a default assessment: an estimate of what you owe, based on whatever information it already has, such as withholding tax credits, bank data or records from employers and other taxpayers you've dealt with. KRA confirmed in its notice on the 2025 filing deadline that non-filers would face exactly this once 30 June 2026 passed.

Once that assessment lands, the burden shifts to you. File the real return or formally object with evidence, within the time the Commissioner gives you, or the estimate stands and gets enforced as if it were correct. A default assessment is rarely generous to the taxpayer, so it's cheaper to file your own numbers first.

What else can happen if you leave it

• No Tax Compliance Certificate. You need a TCC for government tenders, some job applications, visa and work permit renewals, car import and most loan applications. KRA won't issue one until every applicable return is filed and every tax paid on time, or cleared.
• KRA can collect straight from people who owe you money. The law lets KRA send a written notice to your employer, your bank, or anyone else holding or owing you money, ordering them to pay KRA directly out of what they hold for you, up to the amount you owe.
• Failing to file is technically an offence. Without a reasonable cause, it carries a fine of up to KES 1 million, up to three years in prison, or both.
• Deliberate evasion is treated far more seriously. Knowingly hiding income or falsifying records can mean a fine of up to KES 10 million, or double the tax evaded if that's higher, and up to ten years in prison.

In practice, KRA reaches for penalties, interest and default assessments long before it reaches for prosecution. Criminal cases are kept for persistent, deliberate evaders, not someone who filed three months late.

Does the 2026 tax amnesty cover this?

Only sometimes. KRA's 2026 tax amnesty wipes 100% of penalties, interest and fines built up on or before 31 December 2025, as long as you pay the actual tax owed, or get on an iTax payment plan, by 31 December 2026.

That cutoff matters here. If you missed the June 2026 deadline for your 2025 return, that penalty and interest accrued during 2026, after the amnesty's cutoff, so none of it is covered. The amnesty only clears older debts from 2025 and earlier. For who qualifies and how to apply for those, see our guide to the KRA tax amnesty.

Outside the amnesty, you can still ask KRA to waive a penalty or interest on its own merits. The law lets the Commissioner remit a penalty or interest on request, for genuine hardship or where collecting it would be unreasonably difficult, but the actual tax has to be paid first and you need to show your reasons in writing. Treat it as a discretionary ask, not a right.

How to file now and clear what you owe

1. Log into iTax at itax.kra.go.ke with your PIN and password, or reset your password if you've forgotten it, which happens to most people returning to an account they've avoided.
2. File every outstanding return, one tax period at a time. No income in a period means a nil return, not nothing. See our step-by-step guide to filing KRA returns, or how to file a KRA nil return if that's your situation.
3. Generate a payment slip (PRN) on iTax for any tax, penalty or interest shown on your ledger.
4. Pay through Paybill 222222 on M-Pesa, using the PRN as the account number, or through your bank. Dial *222# if you'd rather pay by USSD.
5. Check your ledger a few days later to confirm the payment and balance cleared.

Mistakes that make this worse

• Assuming no one's chasing you means it's fine. Penalties and interest build quietly in the background. Most people only notice when they need a TCC or a loan and get turned down.
• Paying the tax but not the penalty, or the other way round. iTax tracks them separately, and the one you leave unpaid keeps earning interest.
• Ignoring old PIN problems. If you can't remember your KRA PIN or password, sort that out first. You can't file anything until you're back into your account.
• Assuming a future deadline change helps your old return. KRA has moved the individual filing deadline to 30 April from 2027 onwards. That's a date for a future return. It does nothing for the one you've already missed.

Frequently asked questions

What happens if I haven't filed KRA returns for several years?

Each missed year carries its own late filing penalty and its own interest clock, so the amounts stack up per year rather than as one lump sum. File the oldest outstanding year first on iTax, since interest has been running longest on that one, then work forward.

Is there a penalty for a late nil return in Kenya?

Yes. Even with no income to declare, a nil return filed after the deadline attracts a flat KES 2,000 penalty, because the 5%-of-tax-due option works out to zero.

Can I get a KRA Tax Compliance Certificate with pending returns?

No. KRA requires all applicable returns filed and all taxes paid on time before it issues a TCC. Clear the outstanding returns and any balance, then apply.

Does the 2026 tax amnesty wipe penalties from this year?

No. It only wipes penalties and interest that built up on or before 31 December 2025. A penalty from missing the June 2026 deadline accrued in 2026, so it falls outside the amnesty and still has to be paid or disputed separately.

What's the difference between the late filing penalty and the late payment penalty?

The late filing penalty punishes submitting the return after the deadline. The late payment penalty punishes not paying the tax itself on time. You can owe both at once if you're late on each, plus monthly interest on whatever tax remains unpaid.

Can KRA prosecute you for not filing?

Legally, yes: failing to file without reasonable cause is an offence. In practice, KRA relies on penalties, interest and default assessments for ordinary late filers, and keeps prosecution for people who deliberately hide income or repeatedly refuse to comply.
