What an eTIMS debit note is for
A debit note is the document you issue when the amount on an invoice you already issued needs to go up: you undercharged, added items or services after the original invoice, or a price was corrected upward. It references the original invoice so the trail is clear, and it transmits through eTIMS like any compliant document.
The key distinction is direction. A debit note increases what the customer owes; a credit note decreases it (for returns, overcharges or cancellations). Issuing the right one, referencing the original invoice, keeps your records and your customer's records aligned, which matters because both feed eTIMS and your returns. Confirm the current eTIMS debit note fields and process with KRA.
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 issue an eTIMS debit note
A practical path for a Kenyan business. Work through it in order.
- 1
Identify the original invoice
Find the compliant invoice the adjustment relates to. The debit note must reference it so the trail is clear.
- 2
Confirm the adjustment is an increase
A debit note increases the amount. If you are decreasing it (return, overcharge, cancellation), issue a credit note instead.
- 3
Apply the correct tax treatment
The added amount carries the same tax treatment as the underlying supply, so the VAT is correct on the adjustment.
- 4
Issue and transmit through eTIMS
Issue the debit note through your compliant system so it transmits to KRA and updates your records and your customer's.
- 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
Using a debit note to decrease an amount
That is a credit note. A debit note increases the amount owed. Using the wrong one misstates both parties' records.
Not referencing the original invoice
A debit note must reference the invoice it adjusts, or the trail breaks and the adjustment is hard to validate.
Getting the tax treatment wrong on the adjustment
The added amount carries the same treatment as the underlying supply. Applying a different rate makes the VAT wrong.
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 supplier corrects an undercharge
A wholesaler in Mombasa invoiced a retailer, then realised two cartons had been left off the invoice. Rather than issuing a confusing second invoice, the wholesaler issued an eTIMS debit note referencing the original, for the value of the two cartons at the correct VAT.
The retailer received a clear document increasing the amount owed, tied to the original invoice, that it could claim against. Both sides' records and eTIMS stayed aligned.
The debit note turned a messy correction into a clean, compliant adjustment, with no double-counting and a clear trail for both parties.
Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.
