eTIMS guide

how to void an eTIMS invoice is something every Kenyan business needs to get right under KRA's eTIMS rules. You generally do not delete a transmitted eTIMS invoice. To correct or cancel one, you issue a credit note that references the original to reverse it, then issue a correct invoice if needed. This keeps a clean, auditable trail, which is what KRA expects. This guide explains what it means in practice, the exact steps, the mistakes that cost owners money, and how Veira handles it automatically. Rules and rates change, so treat this as a practical map and confirm the current detail with KRA at kra.go.ke.

Why you correct rather than delete

Once an eTIMS invoice has been issued and transmitted, the compliant way to fix a mistake is not to make it disappear. KRA expects an auditable trail, so a wrong invoice is reversed with a credit note that references it, and a correct invoice is issued if the supply still stands. Quietly deleting records is what creates compliance problems, not solves them.

This applies whether the error is a wrong amount, a wrong buyer PIN, a wrong item or a cancelled sale. The credit note reverses the original cleanly, both parties' records and eTIMS stay aligned, and anyone reviewing the trail can see exactly what happened and why. Confirm the current correction and cancellation process with KRA, as the mechanics can 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 correct a wrong eTIMS invoice

A practical path for a Kenyan business. Work through it in order.

  1. 1

    Identify the wrong invoice

    Find the transmitted invoice with the error and the exact problem: wrong amount, wrong PIN, wrong item or a cancelled sale.

  2. 2

    Issue a credit note referencing it

    Reverse the original with a credit note that references it, so the trail shows the original and its reversal clearly.

  3. 3

    Issue a correct invoice if the supply stands

    If the sale still happened but the details were wrong, issue a fresh correct invoice after the reversal.

  4. 4

    Keep both documents on record

    Retain the original, the credit note and any corrected invoice so the full trail is available if KRA reviews it.

  5. 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. 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

Trying to delete a transmitted invoice

Deleting records breaks the audit trail KRA expects. Reverse with a credit note instead, so the correction is visible and clean.

Reissuing without reversing the original

Just issuing a new invoice without a credit note double-counts the sale. Reverse first, then reissue.

Not referencing the original on the credit note

The credit note must reference the original invoice, or the reversal cannot be tied to what it corrects.

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 cashier fixes a wrong PIN

Worked example

A cashier at a Nairobi hardware shop issued an eTIMS invoice to a business customer but entered the wrong buyer PIN, so the customer could not claim the cost. The temptation was to delete and redo it.

Instead, the shop issued a credit note referencing the original to reverse it, then issued a correct invoice with the right PIN. The customer could now claim, and the trail clearly showed the error and the fix.

The mistake was handled the way KRA expects, with a clean, visible correction rather than a deleted record that would raise questions in a review.

Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.

Frequently asked questions

Can I delete an eTIMS invoice?
Generally no. Once transmitted, a wrong invoice is corrected by issuing a credit note that references it, not by deleting it, because KRA expects an auditable trail. Confirm the current process with KRA.
How do I cancel a wrong eTIMS invoice?
Issue a credit note referencing the original to reverse it, and issue a correct invoice if the supply still stands. Keep all documents on record so the trail is clear.
What if I entered the wrong buyer PIN?
Reverse the invoice with a credit note and issue a correct invoice with the right PIN, so the customer can claim and the correction is visible. Veira makes this a quick, clean step.
Does correcting an invoice this way affect my returns?
The credit note reverses the original in your eTIMS records, so your returns reflect the net position correctly. Reconciling as you trade keeps everything aligned.
Why not just issue a new invoice?
Issuing a new invoice without reversing the original double-counts the sale. Always reverse with a referencing credit note first, then reissue if needed.
Does Veira handle this automatically?
Yes. Veira issues compliant KRA eTIMS invoices on every sale, applies the correct tax treatment, keeps records reconciled and ready for filing, and works offline, so compliance happens as you trade rather than as separate paperwork.
How much does eTIMS-compliant software cost?
KRA does not charge for eTIMS itself; the cost is the software you use to issue and transmit invoices. Veira starts at KES 2,999 a month, includes a free terminal, and has a 30-day money-back guarantee.

how to void an eTIMS invoice comes down to recording the right thing, the right way, through a compliant system, and Veira does exactly that without extra work. See how Veira works, or book a free demo. Always confirm current KRA rules and rates at kra.go.ke, as they can change.
