Why eTIMS wrong VAT on invoice happens
eTIMS wrong VAT on invoice is not random. It comes from one of a few specific causes, and once you know which one you are looking at, the fix is straightforward. Here is how the problem usually shows up first:
- VAT charged on a zero-rated or exempt item, or none on a standard item
- A rejected invoice where the VAT does not match the rate
- A customer querying the tax on their receipt
Match what you are seeing to the closest description above, then work through the fixes below in order, starting with the most common.
eTIMS wrong VAT on invoice is rarely random; match the symptom to the cause and the fix is usually minutes away.
How to fix eTIMS wrong VAT on invoice
Work through these in order. Most businesses resolve it at step one or two, without contacting KRA.
- 1
Set the correct tax type per item
Each product should be standard-rated, zero-rated or exempt in line with the VAT schedule. If an item is misclassified, the VAT will be wrong. Correct the item's tax type so the VAT recalculates correctly.
- 2
Re-issue an unconfirmed invoice
If the invoice has not been confirmed, just correct the rate and submit again. The corrected VAT will then appear on the valid invoice.
- 3
Use a credit note for a confirmed wrong invoice
If the wrong invoice is already confirmed by KRA, issue a credit note to cancel it, then issue a fresh, correct invoice. This keeps your VAT records accurate.
- 4
Confirm your VAT registration status
If you are not VAT-registered, your invoices should not charge VAT at all. If VAT is appearing when it should not, check that your status is set correctly in eTIMS.
What not to do
Do not adjust VAT manually to "look right"
Overriding the VAT figure without fixing the item's tax type misreports tax. Correct the classification so the VAT is calculated properly.
Do not leave a confirmed wrong invoice uncorrected
It will misstate your VAT return. Use a credit note and reissue.
A worked example
An agrovet in Meru charged VAT on fertiliser, which is zero-rated. A farmer questioned the receipt, and the owner realised the item had been set as standard-rated.
He corrected the fertiliser to zero-rated, so no VAT applied, and re-issued the invoice. For the earlier confirmed invoices, he issued credit notes and reissued them correctly, keeping his VAT return accurate.
Getting each item's tax type right at setup, especially in trades that mix rates, prevents wrong VAT from the start.
Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.
Veira signs every sale to KRA eTIMS automatically, so each receipt is compliant the moment it prints, with no separate device to reconcile.
How Veira keeps this from happening
