Kenya PAYE penalties and filing deadlines in 2026: what employers risk

Payroll ran on the 28th. Salaries are out. Everyone's happy. Then someone remembers PAYE hasn't been filed yet — and the due date was days ago.

This is one of the most common ways Kenyan employers end up owing the Kenya Revenue Authority (KRA) money they didn't budget for. Not because they refused to pay, but because payroll and tax filing got treated as two separate jobs instead of one process. Here's what's actually at stake, and how the penalty math works.

When is PAYE due in Kenya

Under the Income Tax Act (Cap 470), an employer must deduct PAYE from employee salaries and remit it to KRA by the 9th day of the month following the payroll month. Pay your June salaries, and June's PAYE is due by 9 July.

Filing and payment both happen through iTax, KRA's online tax platform. There's no grace period built into the date itself — the 9th is the 9th, whether it falls on a weekend or a public holiday. Confirm current treatment of weekend/holiday due dates directly with KRA or your tax advisor, since practice on this point can shift.

Separately, employers file an annual PAYE return (the P10 employer return) for the full tax year, which is generally due by the end of February following the year-end. This return reconciles what was deducted and remitted monthly against actual annual employee earnings — it's where under-deductions or over-deductions from the year get caught, often too late to fix quietly.

What happens if you file late

KRA's Tax Procedures Act, 2015 sets out the penalty framework that applies across most tax obligations, including PAYE. A late-filed return attracts a penalty calculated as the higher of a fixed shilling amount or a percentage of the tax due — the exact figures have been adjusted over time via Finance Act amendments, so confirm the current late-filing penalty rate directly on the KRA iTax portal or with a licensed tax agent before you rely on a specific number.

What matters operationally: the penalty is assessed automatically once the deadline passes, independent of whether you've actually paid. Filing three days late and paying in full the same day still triggers the late-filing penalty. Filing on time but paying late triggers a separate, different penalty. The two are not the same event to KRA's system, and both can hit in the same month if you're behind on both fronts.

What happens if you pay late

Late payment is treated separately from late filing under the Tax Procedures Act. It generally involves:

• A late payment penalty, calculated as a percentage of the unpaid tax
• Interest that accrues monthly (or part thereof) on the outstanding balance until it's cleared

Interest compounds the longer the balance sits unpaid — a small PAYE shortfall from March can still be growing in June if nobody closed it out. This is the mechanism, not a fixed number: the specific penalty percentage and monthly interest rate are set by the Act and periodically adjusted, so verify the live figures on KRA's website rather than working from a number you saw last year.

The pattern to remember: filing late and paying late are two separate defaults, each with its own penalty, and interest keeps running on any unpaid balance until it's settled — not until you file.

A worked example (mechanism, not a rate quote)

Say an employer owes KES 200,000 in PAYE for a given month, due 9th, and doesn't file or pay until the 15th of the following month.

That employer is now looking at three separate charges from KRA:

1. A late-filing penalty, assessed once the return is submitted after the deadline
2. A late-payment penalty on the KES 200,000 outstanding
3. Interest for the period the tax remained unpaid

None of these are negotiable line items — they're calculated by KRA's system against the Tax Procedures Act's formulas. The only real control an employer has is not triggering them in the first place. We're deliberately not stating exact shilling amounts here because the specific rates move with Finance Act changes — check the current penalty and interest rates on KRA's iTax portal before you calculate exposure for your own business.

Common employer mistakes that trigger this

• Treating PAYE as a finance task disconnected from payroll. If HR runs payroll on one system and finance files tax separately days later, gaps open.
• Missing the annual P10 reconciliation. Monthly PAYE can be correct but the year-end reconciliation catches accumulated rounding or bracket errors — miss the February deadline and you're compounding a filing default on top of whatever the reconciliation reveals.
• Assuming a short delay is harmless. KRA's penalty and interest structure doesn't have a meaningful "small delay" exception — the clock starts the day after the deadline.
• Not tracking NSSF and SHA deadlines separately. PAYE, NSSF, and SHA (formerly NHIF) contributions have their own filing and remittance dates. They're often close together but not identical, and each authority runs its own penalty regime.

How to stay ahead of it

The employers who never see a PAYE penalty aren't the ones with the best tax lawyers — they're the ones whose payroll run automatically produces the tax filing, on the same day, without a manual handoff. If payroll close and PAYE remittance are the same action instead of two separate to-dos on two separate calendars, the 9th stops being a deadline you have to remember.

Does AnooreHR handle this?

Nigeria runs live on AnooreHR today — full payroll, PAYE calculated automatically on every run, self-service payslips the moment payroll closes. Kenya is on the roadmap as the next country profile pack: the same engine, described to KRA's rules instead of the NRS's, so when it ships, rate or bracket updates from KRA become pack updates, not code rewrites — not a rebuild.

What AnooreHR does not do: file your PAYE return or pay KRA on your behalf, or tell you the exact current penalty percentage — that number lives with KRA and changes with Finance Act amendments, so always confirm it there. Our AI assistant can flag a missed remittance date or an unusual month-over-month PAYE variance, but it drafts, it doesn't file — a human approves and submits.
