What to keep, why retrievability matters more than completeness, and the specific gaps that turn a routine review into a reconstruction exercise.
Records exist to answer questions later, under conditions where memory is unavailable and the person who knew has left. That framing decides everything about what to keep and how.
Retrievable beats complete
A box of receipts in the back room technically satisfies keeping records and satisfies nothing else. The test worth applying is narrower and harder: could a specific transaction from eight months ago be found in a few minutes? If not, the records exist but do not work, and the difference only becomes apparent when someone is asking. Businesses that find a review manageable are rarely the ones with the best systems. They are the ones that filed as they went, so the review is a retrieval exercise rather than a reconstruction.
The buying side is where the exposure sits
Most businesses concentrate on the documents they issue. The greater exposure is usually in the documents they receive, because that is where deductions come from. An expense that cannot be substantiated is an expense that cannot be claimed, which means tax computed on a larger profit than the business actually made. This accumulates quietly across a year and is discovered at the point of computing a position, when it is too late to fix.
An audit you can do this week
List the ten suppliers the business spends most with. For each, answer three questions. Do you receive a proper tax invoice? Do you keep it? Could you produce one from six months ago? The gaps in that list are the gaps in the position. This takes an afternoon and is more useful than most of what is written about compliance, because it converts an abstract obligation into a specific list of suppliers to talk to.
Reconciliation is a record, not an activity
Money received and sales recorded are two separate records, and reconciliation is the act of making them agree. When they do not, exactly one of three things happened: a sale was not recorded, a payment went somewhere else, or something was counted twice. Which one it was matters, and there is no way to tell without checking at the time. This gets harder faster than the business grows. One owner taking payments on one number can hold it in their head. Add a second till and a member of staff, and it stops being holdable, usually a few months before anyone notices.
What good looks like in practice
For most Kenyan businesses, adequate records mean four things kept currently rather than assembled later: what was sold and to whom, what was bought and from whom, what money arrived and through which channel, and what stock is actually on hand. Everything a tax computation needs is derivable from those four. Nothing is derivable from memory.
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.
