Fixing VAT mismatches on iTax doesn’t happen through a special button or a complicated menu path. Instead, the Kenya Revenue Authority (KRA) uses a VAT Auto Assessment (VAA) process that notifies both the buyer and the seller of any inconsistencies. The correction happens through the normal VAT amendment process, and whichever party declared incorrect details must revise their VAT return to match the accurate transaction.
Here is the accurate, verified, and simplified explanation of exactly how and where VAT mismatch corrections happen on iTax:
When a mismatch occurs, KRA automatically sends an Inconsistency Report to both parties:
This report is sent to the registered email on iTax and contains:
This is your first point of reference before logging into iTax.
Before logging in, both parties must agree on:
Correct invoice number
Correct invoice date
Correct taxable amount
Correct VAT amount
Correct supplier PIN
KRA requires the party whose entry is wrong to correct their return.
This ensures both sides of the transaction match perfectly.
To correct the mismatching entry, log into your iTax account and proceed to the VAT return amendment area.
Unlike old guides that list long menu paths, the real and verified location is within the amended return workflow.
Log into your KRA iTax account.
Go to the section labelled “Amend Return” or “File Amended Return.”
Select VAT (Value Added Tax).
Choose the tax period where the mismatch occurred.
Update the correct invoice details.
Ensure the details match the other party’s corrected declaration.
Submit the amended return.
This is the only official way mismatches are corrected in iTax.
If the mismatch originates from someone else—for example:
The supplier failed to declare your invoice
The amounts they declared do not match your claim
They entered the wrong invoice details
Then they must amend their VAT return—not you.
Once they file their amendment, your mismatch will automatically clear after the iTax system synchronizes the data.
After both sides correct their returns:
Check your email for a follow-up notification
Log back into iTax
Open the VAT Auto Assessment or Inconsistency Report section
Confirm that the invoice no longer appears under mismatches
Check your VAT ledger for updated entries
If the mismatch remains, it may be due to:
The supplier not submitting their amendment
A second mismatch in the same invoice
A timing delay in the iTax system
An error requiring KRA support
KRA allows taxpayers to escalate unresolved mismatch issues through:
