What Is eTIMS in Kenya? The System Explained

If you run a shop in Kenya and you've heard the letters eTIMS but never quite had them explained, this is the guide for you. eTIMS is KRA's Electronic Tax Invoice Management System — the way the taxman now sees what you sell, in real time, without ever walking into your shop.

It matters to you because it sits underneath nearly everything else in this tax series. Understand eTIMS and the rest of your tax life — turnover tax, VAT, records, audits — becomes clearer. So let's strip the jargon off it.

How eTIMS works, in one paragraph

You make a sale and generate an invoice for it. The invoice goes to KRA's system, which checks it and hands back an authorization code — the AUTH code — in real time. The invoice now carries that code and a QR code, and the sale is logged in KRA's records. Customer happy, sale closed, and the taxman already knows. That's the whole loop.

The four ways to run eTIMS

• eTIMS Lite (web portal) — generate invoices in your browser. Fine for low volume, painful for a busy counter.
• eTIMS Mobile App — invoicing from your phone. Great for traders on the move, not built for checkout speed.
• eTIMS offline desktops (Lite/Standard) — KRA's desktop apps with a USB token that signs invoices. Workable, but still manual per invoice.
• POS / API integration — your till talks to eTIMS directly, so every sale gets an authorized invoice automatically. The only option that scales with a real shop floor.

The first three are manual — someone has to create an invoice per sale, which is why they suit low-volume traders. The fourth is automatic, which is why it suits shops. If your till generates the invoice the moment the sale closes, the AUTH code and QR code appear without anyone lifting a finger.

What eTIMS means for a mini-mart owner

• Every sale can (and should) produce an eTIMS-compliant invoice — even small cash sales, because KRA can now see your turnover directly.
• Your stock and your invoices should agree. An invoice trail that doesn't match your shelves is exactly the inconsistency an audit looks for.
• If a customer asks for a receipt, the invoice you hand them carries KRA's authorization — which is why it's also better for customer trust.
• Month-end reporting stops being a reconstruction. The data is already with KRA; you're just confirming it.

Where eTIMS fits in your overall tax picture

eTIMS is not a tax you pay — it's the invoice system under every tax you pay. Your turnover tax and VAT are calculated from the sales you report, and eTIMS is what makes that reporting verifiable. That's why the penalty for dodging it is serious, and why the smart play is to make it automatic.
