eTIMS for small businesses in Kenya: what to know and how to stay ahead

Tax feels heavy. It does not have to.

Why it matters

eTIMS is KRA’s electronic tax invoice system. KRA says everyone engaged in business needs to onboard and issue electronic tax invoices. For many small shops it arrived as a worry, not a help: new rules, separate tools and the fear of getting it wrong.

It also affects what you buy. Business expenses generally need to be backed by an eTIMS invoice to be claimed as deductions, so your suppliers and your own records both matter. Confirm the details with KRA or your tax advisor.

What it changes day to day

How to stay ahead

  1. Onboard on the KRA eTIMS system.
  2. Sell through a till that keeps sales and receipts in one place.
  3. Reconcile M-Pesa against sales every day, not every month.
  4. Keep supplier invoices where you can find them.
  5. Review your numbers monthly before the deadline, not on it.

How Omnistack bridges the gap

Omnistack POS is built so the till, M-Pesa and your tax records live in one place. Compliance becomes a by-product of selling, not a separate chore. Whether you run a kiosk in Hustler mode or a pharmacy in Business mode, the habit is the same: sell, record, stay in line.
