The short answer
An invoice has to identify what was sold and, where the buyer is a business that will claim the purchase, identify that buyer — which in practice means capturing their PIN at the counter rather than reconstructing it afterwards.
What the rules say
This page explains how a requirement generally works. It is not tax advice, and it cannot account for the specifics of any one business. For a position you intend to rely on, confirm with KRA directly or with a registered tax agent.
Tax rules in Kenya change with each Finance Act and with regulations made during the year. Before acting on any figure, deadline or threshold, check the current position on KRA's own website.
What we are not stating here. Some of the specific requirements relating to this topic have not yet been verified against their primary source by our reviewer, so they are withheld from this page rather than stated from memory. That means you will not find a threshold, rate, deadline or penalty figure below. For those, check KRA directly. Everything else on this page explains how the mechanism works and is not affected.
The detail that causes most of the trouble
Where the buyer is a business that will claim the purchase, its PIN has to be on the document. Capturing it at the counter takes a few seconds. Reconstructing it afterwards, from a customer who has left, against a sale that is already recorded, is a different job entirely and often does not get done. Almost every invoicing problem a Kenyan business has is some version of this: information that was easy to capture at the moment and expensive to recover later.
A receipt and a tax invoice are not the same document
Most retail sales are receipts. The customer wants proof they paid. A tax invoice is a different instrument with prescribed contents, issued because the buyer needs it for their own tax position. A business that treats every sale as one or the other will be wrong in both directions: producing formal documents nobody needs for walk-in trade, and producing till slips for the customers who needed something more.
What to do when the connection drops
Kenyan trading areas do not all have reliable connectivity, and a business that cannot sell when the network is down has a worse problem than a compliance one. The question to ask of any setup, before buying it, is what it does during an outage and what happens to those transactions when the connection returns.
How this works in practice
- Capture what was sold, in the units the customer is buying.
- Where the buyer is a business claiming the purchase, capture their KRA PIN at the counter, not afterwards.
- Issue the invoice through your eTIMS channel and keep the validated copy.
- File the copy where you will find it again: the record is what supports the claim, not the memory of the sale.
