Sales Tax Refunds After Digital Invoicing (2026): FASTER, Annexure-H and the 72-Hour Rule

A refund is money FBR pays back to you when the sales tax you paid on purchases is more than the sales tax you collected on sales.

Exporters end up in this position almost every month, because exports are zero-rated (taxed at 0%), so there is very little tax to collect.

This guide explains the FASTER system that pays those refunds, the Annexure-H form that starts the claim, and the one thing digital invoicing changed about all of it.

FASTER stands for Fully Automated Sales Tax e-Refund. It is FBR's automatic refund engine. No officer approves your claim by hand — the system checks it and pays it.

Rule 39F of the Sales Tax Rules 2006 sets the target: a claim processed through FASTER should be settled within 72 hours of filing. FASTER was built for the five export-oriented sectors — textiles, leather, carpets, sports goods and surgical goods.

The payment path is automatic too. FASTER issues an RPO (Refund Payment Order — the instruction that says how much you are owed), sends it to the State Bank of Pakistan, and the State Bank passes it to your commercial bank, which credits your account.

Be realistic about the timing. 72 hours is what the rule says. Exporters have complained publicly for years that real refunds take much longer when a claim gets held for a check. Treat 72 hours as the best case, not a promise.

The honest reason most claims are slow is not the system being down. It is that something in the claim did not match FBR's own record. That is where digital invoicing comes in.

You do not file a separate refund application. Inside your monthly sales tax return there is a form called Annexure-H — a stock statement showing what you bought, what you used, what you exported and what is still lying in your store.

When you submit Annexure-H, FBR treats that as your refund claim being filed. The 72-hour clock in rule 39F starts from there.

Annexure-H has a deadline of its own. If you file your return but leave Annexure-H for later, your refund has not been claimed yet — only the return has been filed. Many businesses lose a month this way without realising it.

So the order is simple: file the return, then file Annexure-H, and only then does FASTER have anything to work with.

A refund is only ever as good as your input tax (the sales tax your suppliers charged you). FASTER pays you back that input tax. If FBR cannot see the input tax, it cannot pay it.

Before digital invoicing, you typed your purchase invoices into the return yourself. Now your supplier posts the invoice to FBR and it appears in your Annexure-A automatically. If your supplier never posted it, the tax is simply not there — and neither is that part of your refund.

This is the single biggest change for exporters. Your refund is now partly in your suppliers' hands. A cotton trader or a fabric supplier who has not integrated with FBR is not only their own problem — their missing invoice is a hole in your refund claim.

Our guide "Annexure-A After Digital Invoicing (2026): Your Purchase Register, Input Tax and the Missing-Invoice Problem" covers what to do when an invoice you paid for never shows up.

Before you buy from a new supplier, it is worth doing the check described in "How to Check a Supplier Before Claiming Input Tax: FBR Invoice, ATL & Registration Checks (2026)". Five minutes there saves a month of refund chasing.

There are now two well-known 72-hour rules in FBR's sales tax world, and people confuse them constantly.

The first is the refund rule. Rule 39F says a FASTER refund claim should be processed within 72 hours of filing. That clock is about money coming to you.

The second is the invoice correction rule. Under STGO 01 of 2026, a digital invoice can only be cancelled, deleted or edited within 72 hours of being generated, and only for a genuine mistake. That clock is about fixing a document.

They are unrelated. Missing the invoice-correction window does not affect your refund window, and vice versa. But both are short, and both punish waiting.

Work through it in this order, because the cheapest fixes come first.

One — check Annexure-A line by line against your own purchase file. Every invoice you paid tax on should be sitting there. List the ones that are missing.

Two — for each missing invoice, contact that supplier and ask for the IRN (Invoice Reference Number — the unique number FBR gives an accepted invoice). If they cannot produce one, the invoice was never posted and they must fix it at their end. Do not enter it by hand.

Three — check the NTN on the invoice. A supplier who posted the invoice against a wrong or old NTN has sent your input tax to somebody else's account.

Four — confirm your own Annexure-H was actually submitted, not just saved. A saved form is not a filed claim.

Five — if all of that is clean and the refund still has not moved, the claim is probably held for a manual check. That is when you raise it with your Regional Tax Office, with the return period and the claim amount in writing.

If you export, also read "FBR Digital Invoicing for Exporters: Zero-Rated Supplies and IRNs (2026)" and "Zero-Rated vs Exempt Invoices in FBR Digital Invoicing", because a supply booked as exempt instead of zero-rated quietly kills the refund on it.

If your own invoices are not yet going to FBR in real time, that is the first thing to fix — you can register on Digi Invoice and start posting compliant invoices before your next return is due.

Refund — money FBR pays back when the tax you paid on purchases is more than the tax you collected on sales.

FASTER — Fully Automated Sales Tax e-Refund, FBR's automatic refund system for the five export sectors.

Annexure-H — the stock statement in your monthly return; submitting it counts as filing your refund claim.

RPO — Refund Payment Order, the instruction that tells the bank how much to pay you.

Zero-rated — taxed at 0%, so you charge no tax but can still claim back the tax you paid.

IRN — Invoice Reference Number, the unique number FBR gives an invoice once it is accepted.
