Income Tax for Shop Owners in Kenya: Sole Proprietors, PAYE & Filing

How income tax works for Kenyan shop owners — the 10/25/30% tax bands, what counts as a deductible expense, PAYE for staff, and the 30 June annual return.

Income tax is the tax on what you actually keep — your profit — and for a shop owner it comes in two flavours: the tax on your own business income, and PAYE for anyone on your payroll. Both are simpler than they sound, and both get dramatically easier when your records are real.

Sole proprietors pay tax on profit, at personal rates

Most mini-marts are sole proprietorships, and Kenya taxes a sole proprietor's business income at the same rates as personal income. For a year of profits:

Annual taxable incomeRate
Up to KSh 288,00010%
KSh 288,001 – 388,00025%
Above KSh 388,00030%
Income tax bands for a sole proprietor: 10 percent up to KSh 288,000, 25 percent to KSh 388,000, 30 percent above, with deductible expenses and PAYE for staff
Bands stack — each slice of profit is taxed at its own rate, and expenses shrink the pile first.

The word that matters is profit. Tax applies to what's left after your genuine business expenses — not to the full value of everything you sold. That single distinction is why two shops with identical sales can owe very different amounts of income tax, and why record-keeping is the whole game.

Expenses that reduce your taxable profit

  • Stock — every purchase from your suppliers, evidenced by their invoices.
  • Rent and utilities — the shop, power, water, and business phone costs.
  • Staff wages — salaries of your employees (which also carry PAYE).
  • Transport and delivery — moving stock from wholesaler to shelf.
  • Repairs and small equipment — keeping the shop running.
  • Business banking, insurance, and professional fees — accountant and licensing costs.

PAYE: the tax on your staff's salaries

The moment you employ someone, you become an employer in KRA's eyes. Register for PAYE, deduct it from each salary at source using the official bands, and remit it by the 9th of the following month. The personal relief makes most low-wage retail staff pay little or no PAYE — but the deduction, remittance, and monthly return still need to happen.

The annual routine

  • Quarterly installment tax through the year if your expected annual tax is above the threshold — four installments that stop June being a shock.
  • Annual income tax return on iTax by 30 June for the previous calendar year.
  • PAYE monthly: deduct, remit by the 9th, file the return.
  • Keep your profit and loss honest all year — the return is a summary of records you already have.

Income tax vs. turnover tax

If you're in the KSh 1–25 million turnover band, you're likely on turnover tax (3% of gross) rather than income tax on profits. Some shops choose income tax because their margins are thin and expenses are high — a conversation worth having with an accountant once your books are clean. The numbers are only comparable when the records are real.

Frequently asked questions

How much income tax does a shop owner in Kenya pay?

Sole proprietors pay tax on their business profits at the individual rates: 10% up to KSh 288,000 a year, 25% on the next band up to KSh 388,000, and 30% above that. The rate applies to profit, not turnover — so legitimate expenses genuinely reduce what you owe.

What business expenses can I deduct?

Expenses incurred wholly and exclusively for the business: stock purchases, rent, power, water, transport and delivery, staff wages, repairs, and business-related insurance and banking charges. The rule is simple — every deduction needs a record, so invoices from suppliers and your own till records are the evidence.

When is the income tax return due in Kenya?

The annual income tax return is filed through iTax by 30 June following the end of the year (the tax year runs January to December). If your expected tax is significant, you also pay quarterly installment tax during the year rather than one painful lump in June.

Do I pay PAYE as a mini-mart owner?

If you employ staff — cashiers, shop attendants, stock clerks — yes. You register for PAYE as an employer, deduct it from each employee's salary at source, and remit it to KRA by the 9th of the following month. It's a withholding tax: the money comes out of salaries, and your job is to pass it on.
