Taxes for Mini-Marts in Kenya: The Complete eTIMS & KRA Guide

Running a mini-mart in Kenya means juggling rent, suppliers, stock, and staff — and somewhere in the middle of all of it, the tax man. It's tempting to treat taxation as a month-end mystery best left to an accountant, but for a shop owner the basics are surprisingly small: a handful of taxes, a few deadlines, and one system — eTIMS — that sits underneath all of it.

This is the pillar guide for the whole series. It maps out every tax a Kenyan mini-mart owner deals with, explains what each one means in plain language, and points you to a dedicated guide for each topic. Read the sections that apply to your shop, then follow the links to go deeper.

The tax map for a Kenyan mini-mart

Before we go deep, here's the whole landscape on one page. Every row is its own guide in this series:

1. eTIMS: the system under everything

eTIMS — KRA's Electronic Tax Invoice Management System — is how KRA now watches retail sales. You generate an invoice for a sale, KRA issues an authorization (AUTH) code for it in real time, the invoice carries a QR code, and the sale lands in KRA's records. It replaces the old ETR machines and it's how the taxman can see your turnover without ever visiting your shop.

You can use eTIMS through KRA's web portal, the eTIMS mobile app, an offline desktop app, or — the option that matters for a shop — through a POS system that issues eTIMS-ready invoices automatically. Every invoice your till generates can carry the authorization code and sync to KRA without anyone retyping anything.

2. Turnover tax (TOT): the default for most mini-marts

If your mini-mart's annual turnover sits between KSh 1 million and KSh 25 million — which describes the vast majority of Kenyan mini-marts — turnover tax is likely your main income-related tax. It's a flat 3% of gross turnover, filed monthly through iTax by the 20th of the following month. No deductions, no expense schedules, no arguments: 3% of what you actually sold.

The trade-off is that TOT is charged on turnover, not profit — so even a thin-margin month still owes its 3%. That's exactly why the shops that thrive keep their margins healthy and their records clean, rather than trying to make the numbers disappear.

3. VAT: only once you cross the line

VAT is the tax most shop owners worry about — and for most mini-marts, it never actually applies. VAT registration becomes mandatory only when annual taxable turnover passes KSh 8 million (raised from KSh 5 million by the Finance Act 2023). Below that, you don't charge VAT to customers, and you don't file VAT returns. Above it, you charge 16% on taxable sales and file monthly by the 20th.

There's a nuance that suits mini-marts: many staples — maize flour, milk, unprocessed foods — are zero-rated or exempt, so a shop heavy on essentials may owe very little output VAT even after crossing the threshold. If you're edging toward KSh 8 million, read the VAT guide before you get there, not after.

4. Income tax & PAYE: your profits and your staff

Sole proprietors pay income tax on their business profits at the personal rates: 10% up to KSh 288,000 a year, 25% up to KSh 388,000, and 30% above that. The annual return goes in through iTax by 30 June. If you employ cashiers or shop attendants, you're also an employer: register for PAYE, deduct it from salaries, and remit it by the 9th of every month.

The golden rule that keeps income tax small: pay it on profit, not turnover. Every legitimate business expense — stock, rent, power, transport, staff wages — reduces your taxable profit, but only if you have the records to prove it. A till that keeps your sales and stock honest is the same tool that keeps your tax honest.

5. Excise duty: usually not your problem to file

Excise duty is a tax on specific goods — sweetened sodas and juices, alcohol, cigarettes, and a few others. Here's what most mini-mart owners need to know: by the time those goods reach your shelf, the excise duty is already baked into the wholesale price you paid. You don't charge it separately at the till, and you don't register as an excise licensee unless you manufacture or import the goods yourself.

The one real risk for a shop is stock that arrived without duty paid — cheap cigarettes or drinks that somehow cost far less than the market rate. That's not a bargain, that's a liability. If a price is too good to be true, it usually means the duty isn't in it.

6. Records and penalties: what KRA can demand

KRA can ask to see your records for up to five years — sales, purchases, invoices, stock movements, and payroll. If your records are an exercise book updated from memory, that's a stressful conversation waiting to happen. If they're generated automatically by your till, it's a file you hand over.

The penalties for getting it wrong are real: monthly penalties for late returns, interest of 1% per month on unpaid tax, and fines of up to KSh 1 million with possible imprisonment for serious eTIMS violations — like failing to issue electronic invoices at all. None of it is worth the shortcut.

7. The one thing that makes all of this easier

Notice a pattern? Every tax on this list gets harder the further your records are from reality. The shops that sail through tax season aren't the ones with better accountants — they're the ones whose till generates the paper trail for every sale, automatically, without anyone reconstructing it at month end.

Kiosk.ke is built on that idea: a point-of-sale that scans products, takes M-Pesa, tracks stock, and keeps every invoice ready for eTIMS reporting — so when your accountant asks for numbers, they're already there, accurate, dated, and reconciled with what's actually on your shelves. eTIMS compliance becomes a background process instead of a monthly archaeology project.

Your tax checklist as a mini-mart owner

• Register your business and get your KRA PIN attached to it, not just to you.
• Onboard to eTIMS — ideally through a POS that issues compliant invoices automatically.
• Know your tax type: turnover tax (under KSh 25M), income tax on profits, or VAT (over KSh 8M).
• Put the deadlines in your calendar: 20th monthly for TOT/VAT, 9th monthly for PAYE, 30 June for the annual return.
• Keep five years of records — and let your till generate them for you.
• Never buy duty-suspicious stock. A cheap cigarette is an expensive liability.
