August 2026 Sales Tax Return Extensions: General and Restricted Deadlines

Updated 1 October 2026: This page preserves the general September 25 extension and explains a later, restricted extension. Do not use the old headline as the deadline for every taxpayer.

What the September 18 directive covered

FBR’s directive dated 18 September 2026 extended submission of August 2026 Sales Tax and Federal Excise returns to 25 September 2026 for all taxpayers, provided the due sales-tax liability had been deposited on time. That filing date has passed.

Later relief is limited to named taxpayers

The 30 September 2026 directive extends August-period return submission to 2 October 2026 for DISCOs/K-Electric and taxpayers added to STGO 10/2026 dated 14 July 2026. It retains the condition that due sales-tax liability was deposited within the due date. This is not a fresh extension for all businesses.

How to check whether the later directive applies

1. Confirm that the return concerns the August 2026 tax period.
2. Check whether your entity falls within the categories named in the September 30 directive. Do not assume eligibility merely because you have an August return outstanding.
3. Retain the relevant payment receipt and compare its date and amount with your liability.
4. Reconcile invoices, sales, purchases, input tax and output tax before submission.
5. Keep the final submission evidence and any advice received about your eligibility.

A filing extension and a payment extension are different. These directives do not justify treating the extended submission date as permission to delay payment. If payment was late, or you are outside the named category, obtain advice on your actual filing position rather than relying on the headline.

Keep different taxes and periods separate

The August sales-tax/FED directives do not set the deadline for an annual income-tax return. Our income-tax filing checklist includes a separate update and preparation steps.

For the routine monthly timetable, consult FBR’s sales-tax due-date guidance. For new directives, check the official notice board. A timetable summary should always be read alongside a directive covering your own period and taxpayer category.

If an IRIS discrepancy appears during preparation, see our sales-tax scrutiny guide. The message in your account should be read carefully and answered with records supporting your figures.
