How to File Late VAT Returns in Kenya When Input VAT Is Rejected (April 2025 Case)

Late VAT filing in Kenya can feel like walking into a locked room with the lights off. Many taxpayers only discover the lock when iTax suddenly rejects all purchase invoices, even though the dates look perfectly valid.

This article explains why iTax rejects April 2025 purchase invoices when filing late, and the exact workaround that works, based on a real filing outcome.

The Problem: Input VAT Rejected During Late Filing

While filing April 2025 VAT returns late, the iTax system displays errors similar to:

Invoice date should be on or before the return period only; however, it cannot be a date prior to 7 months from date of filing.

The confusing part is that:

• All invoices are dated April 2025
• The return period selected is April 2025
• Invoice numbers and suppliers are valid

Yet every purchase invoice is rejected.

What iTax Is Actually Checking

The system applies two separate validation rules, not just one.

1. Return Period Rule

The invoice date must fall within the selected VAT period.
✔ April 2025 invoices pass this check.

2. The 7-Month Input VAT Rule (The Hidden Gate)

Input VAT must be claimed within 7 months from the invoice date, calculated up to the actual date of filing, not the VAT period.

This rule is enforced by Kenya Revenue Authority under VAT law and strictly implemented in iTax.

Why April 2025 Invoices Get Rejected

If you are filing in:

• December 2025
• January 2026
• Or later

Then April 2025 invoices are older than 7 months.

Result:

• iTax automatically blocks them
• No override button
• No partial acceptance

The system is doing exactly what it was designed to do.

The Solution That Actually Works

✅ File the VAT Return Without the Purchase Invoices

This method is fully compliant and accepted by iTax.

Steps:

1. Open VAT → File Return
2. Select April 2025
3. Leave General Rated Purchases empty
4. Declare output VAT only
5. Submit the return
6. Pay the VAT due

✅ The return submits successfully
✅ No system errors
⚠ Input VAT is forfeited

This is the only guaranteed method once the 7-month window has closed.

Why This Works

At that stage, iTax is no longer rejecting the return.
It is rejecting the claim of input VAT.

By removing the purchase invoices:

• You comply with system rules
• You close the late filing obligation
• You avoid penalties escalating further

Common Questions

Can I amend the return later to add the invoices?

No. Amendments are still subject to the same 7-month rule.

Can KRA manually approve the invoices?

Only in rare cases, after lodging a complaint. Approval is not guaranteed.

Is this method legal?

Yes. You are allowed to file VAT returns without claiming input VAT.

Key Lesson for VAT-Registered Businesses

Input VAT is time-sensitive. Filing late can permanently erase your right to claim it.

To avoid this:

• File VAT monthly, even with zero activity
• Do not wait to “batch” returns
• Track invoice dates versus filing dates
