How to Handle eTIMS Credit Notes and Invoice Corrections in Kenya

A tax invoice transmitted through the electronic Tax Invoice Management System (eTIMS) cannot be edited, deleted or recalled once the Kenya Revenue Authority (KRA) has received it. You cannot cancel an eTIMS invoice at that stage either. Any eTIMS invoice correction in Kenya runs through a credit note that references the original invoice number, followed by a new invoice if the sale still stands. Getting this sequence right protects the seller’s Value-Added Tax (VAT) figures and the customer’s right to claim input VAT.

Why do eTIMS invoices need a formal correction process?

eTIMS sends each invoice to KRA as it is issued, where it becomes part of the seller’s sales record and the buyer’s purchase record. The auto-populated VAT return draws on this data, so an invoice that could be deleted or overwritten would leave KRA’s figures out of step with the business’s books.

Deleting the PDF copy or voiding the entry in the local accounting system does not cancel an eTIMS invoice in KRA’s records. The VAT (Electronic Tax Invoice) Regulations, 2020, instead provide for invoice reversal in Kenya through credit notes or debit notes, each of which must reference the original invoice number.

Only invoice drafts that have not been transmitted to KRA can be edited freely. A network timeout does not necessarily mean the invoice was rejected. Check its transmission status before resending it to avoid creating a duplicate invoice.

What is an eTIMS credit note?

An eTIMS credit note is a document issued by the seller through the same eTIMS solution used for the original invoice and transmitted to KRA. It reduces or reverses the value of an invoice already recorded in KRA's system. The credit note references the original invoice number, allowing KRA to link the adjustment to the relevant sale. A KRA credit note issued for this purpose reduces the seller’s output VAT and the buyer’s corresponding input VAT by the same amount.

Section 16 of the VAT Act, 2013 requires a credit note when goods are returned or the value of a supply decreases after a tax invoice has been issued. An eTIMS sales credit note can take one of two forms:

• Full credit note: Reverses the entire invoice. Use it when the sale is cancelled, or the entire transaction needs to be reversed.
• Partial credit note: Adjusts specific items, quantities or amounts while keeping the rest of the invoice valid.

A credit note cannot exceed the value of the original invoice and must relate to items included in that invoice. If the seller undercharges, the adjustment works in the opposite direction. The seller issues a debit note referencing the original invoice to increase the taxable value.

Which common scenarios need an invoice correction?

The table below shows the correction for each common error and its effect on VAT:

Note: The VAT adjustment depends on the transaction and the applicable tax rules. Both parties’ records should show the same correction, and the credit or debit note must reference the original invoice. 

A discount printed on the original invoice needs no correction because VAT was charged on the discounted price. A discount agreed after the sale reduces the value of the supply, so it needs a credit note.

How do you correct a wrong or missing buyer PIN on eTIMS?

A wrong buyer PIN, or a missing one, can prevent the customer from claiming input VAT. A wrong PIN links the purchase to another taxpayer, while a missing PIN records the sale without identifying the registered buyer. 

The seller corrects the error as follows:

1. Issue a full credit note: Reverse the original invoice with a credit note that references its invoice number.
2. Verify the buyer’s PIN: Confirm the correct KRA PIN using the PIN checker on the iTax portal.
3. Issue a corrected invoice: Generate a new eTIMS tax invoice with the correct buyer PIN and the original transaction details.
4. Send the new invoice to the buyer: Share the corrected invoice so the buyer can use it to support an input VAT claim.

According to KRA’s guidance, the buyer can claim input VAT on the corrected invoice in the following month, subject to the applicable requirements. If the buyer did not provide their PIN when making the purchase, they should contact the seller and request a full credit note and a replacement invoice with the correct PIN.

Why must a KRA credit note come from the same eTIMS solution?

KRA allows a credit note only from the eTIMS solution where the original invoice was raised. eTIMS offers several solutions, including the online portal, eTIMS Lite and system-to-system integrations such as the Online Sales Control Unit (OSCU). Each keeps its own invoice sequence, so a credit note raised elsewhere has no original invoice to point to.

If you switch from the eTIMS online portal to an integrated system, you must still issue credit notes through the portal for invoices originally raised there. Keep access to every eTIMS solution you have used until the six-month period for issuing a credit note against its last invoice has expired.

How do credit notes affect your VAT return?

Credit notes adjust the sales and VAT reported by both the seller and the buyer. The impact depends on whether you issued the credit note or received it.

Seller’s VAT return

If you issued the credit note, it changes your VAT return as follows:

• A credit note reduces reported sales and output VAT. Include it in the sales CSV file you upload for the VAT return in Kenya.
• If you declare a credit note issued to a VAT-registered customer as a separate line item, the corresponding original invoice must also have been declared as a separate line item in the VAT return for the tax period in which that invoice was issued.

Buyer’s VAT return

If you received the credit note, it changes your VAT return as follows:

• A credit note reduces eligible purchases and input VAT. 
• If you have already claimed input VAT on the original invoice, reduce the deductible input VAT by the tax amount shown on the credit note. You must make this adjustment in the month you receive the credit note, as required under Section 16(3) of the VAT Act, 2013.

Deadlines

Two time limits apply to credit notes and the input VAT they affect:

• Credit note: Issue it within six months of the date of the relevant tax invoice. If a commercial dispute concerning the supply's price is resolved through court proceedings, the credit note may be issued within 30 days of the court's determination.
• Input VAT on purchases: Claim eligible input VAT within six months after the end of the tax period in which the supply took place, subject to the applicable requirements.

How do you keep invoices, credit notes and books aligned?

Follow these practices to keep your eTIMS invoices, credit notes, accounting records and VAT returns consistent: 

• Record the credit note in the books on the date it is transmitted to eTIMS.
• Link each credit note to the original invoice and the customer’s ledger.
• Note a clear reason for each credit note, such as goods returned or price error.
• Adjust stock for returned goods.
• Reconcile the eTIMS sales report with the sales ledger before filing the VAT return.
• Keep supporting documents such as goods return notes and written discount approvals.

How does accounting software simplify eTIMS corrections?

When invoicing and bookkeeping run on separate systems, every correction is entered twice. Accounting software in Kenya with eTIMS integration removes that double entry. It also helps in the following ways:

• Credit notes are raised against the original invoice, so the invoice number, buyer PIN and items carry over.
• Validation checks stop a credit note that exceeds the invoiced quantities or values.
• The credit note is transmitted to KRA from the same entry.
• Invoices and edits sit in one audit trail.

Integration still needs checks. If transmission fails, the credit note sits in the books but not with KRA. Review pending documents before you file and confirm that each tax invoice in Kenya and its credit notes show as accepted.

Keep the original invoice for reference, issue a credit note through the same eTIMS solution to correct the error and generate a new invoice only if the sale remains valid. Verify the buyer’s PIN before issuing the invoice to avoid delaying the customer’s input VAT claim. Set an internal deadline well before the six-month limit to ensure corrections are completed on time.

TallyPrime supports eTIMS integration, allowing businesses to generate and transmit invoices and credit notes while maintaining their accounting records. When a business issues a credit note against an original invoice through TallyPrime, the corresponding accounting entries and VAT reports are updated as part of the same workflow.

Businesses should still verify that each document has been successfully transmitted and accepted by KRA. This helps ensure that corrections recorded in the accounting system are also reflected in eTIMS and the VAT return.

FAQs

1. Can I cancel an eTIMS invoice after it is transmitted to KRA?

No. Once KRA accepts an invoice, you cannot delete or void it. You reverse it with a full credit note and issue a new invoice if the sale still applies.

2. How do I correct a wrong buyer PIN on eTIMS?

Issue a full credit note against the invoice, then raise a new invoice with the correct PIN verified on iTax. KRA’s guidance says the buyer claims input VAT on the new invoice in the following month.

3. Can I issue a KRA credit note from a different eTIMS solution?

No. KRA allows a credit note only from the solution where the original invoice was raised, so invoices from an old solution must be credited there.

4. How does an eTIMS sales credit note affect my VAT return in Kenya?

It reduces your sales and output VAT for the period in which you issue it. It appears in the sales CSV of the auto-populated return.

5. Is there a time limit for issuing a credit note in Kenya?

Yes. Under Section 16 of Kenya’s VAT Act, 2013, a credit note must generally be issued within six months of the date of the original tax invoice. If a dispute over the value of a supply is being resolved through court proceedings, a credit note may be issued within 30 days of the court’s determination.

6. Does the buyer need to do anything when I issue a credit note?

Yes, if the buyer is VAT-registered. KRA requires the credit note to be claimed under purchases, which reduces the input VAT available for that period.
