The real cost of not using eTIMS
Under KRA's rules and the 2026 income-validation regime, a business that issues receipts is expected to record sales through a compliant electronic tax invoice system. Not using eTIMS does not just risk a penalty; it quietly costs you business and deductions every day.
There are four distinct costs. First, your sales are not recorded the way KRA expects, which is a compliance exposure. Second, business customers cannot claim what they spend with you without a compliant invoice, so they take their business to a compliant supplier. Third, your own expenses can be disallowed at tax time if your suppliers did not issue compliant invoices, raising your tax bill. Fourth, non-compliance can attract penalties under the Tax Procedures Act. Confirm the current penalty amounts directly with KRA, as they change.
Get this right and it runs quietly in the background of your business. Get it wrong and you risk rejected invoices, disallowed expenses for your customers, and exposure during a KRA review under the Tax Procedures Act. Confirm the current rules and any penalty amounts with KRA, as they change.
Compliance is not extra admin if the system does it for you on every transaction.
How to get compliant quickly
A practical path for a Kenyan business. Work through it in order.
- 1
Confirm your KRA PIN and registration
Make sure you have an active KRA PIN and understand your VAT registration status, since it determines whether you issue VAT or non-VAT eTIMS invoices.
- 2
Choose a compliant system
Pick eTIMS-compliant software that issues a compliant invoice on every sale, works offline, and reconciles M-Pesa, so compliance happens as you trade.
- 3
Map your products to the right tax treatment
Set each product or service to its correct standard, zero-rated or exempt treatment so every invoice validates.
- 4
Start issuing compliant invoices on every sale
From go-live, every sale should produce a compliant eTIMS invoice with the buyer PIN captured for business customers.
- 5
Keep reconciled records
Reconcile what you issue and receive as you go, so any reporting and filing summarise records you already hold rather than a month-end reconstruction. KRA can review records going back several years.
- 6
Confirm the current rules with KRA
Rates, thresholds, exemptions and deadlines change. Before relying on a specific figure, confirm the current position at kra.go.ke or with your tax adviser.
Common mistakes to avoid
Assuming a small business is exempt
Size does not remove the requirement. A small business below the VAT threshold still issues non-VAT eTIMS invoices to record income.
Treating eTIMS as a once-a-year task
eTIMS is recorded as you trade, on every sale, not reconstructed at filing time. Treating it as a deadline job leaves gaps.
Ignoring supplier invoices
Your own expenses need compliant supplier invoices to be deductible. Not collecting them raises your tax bill.
Waiting for a deadline before getting compliant
Every uncompliant transaction is a gap you have to explain later. Getting compliant now is cheaper than catching up under pressure.
Relying on a system that cannot work offline
Connectivity is not guaranteed everywhere in Kenya. Use a system that records offline and transmits to KRA when the connection returns, so you never fall out of compliance during an outage.
A shop owner counts the cost
A general shop in Nairobi kept issuing handwritten receipts and assumed eTIMS was a problem for bigger businesses. Two things changed the owner's mind. A corporate customer who bought in bulk stopped ordering because they could not claim the cost without a compliant invoice. And at tax time, several expenses were questioned because the shop's suppliers had not issued compliant invoices.
The owner adopted a compliant system. Every sale now issues a compliant eTIMS invoice, business customers capture their PIN and can claim, and the shop collects compliant supplier invoices so its own expenses hold up.
Nothing about how the shop sold changed, but the leakage stopped: corporate customers came back, expenses stopped being disallowed, and the compliance exposure went away.
Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.
