Take an advance from a customer, and the tax clock now starts on the day the money arrives — not on the day you deliver the goods.
That is the practical meaning of the Federal Board of Revenue’s newest change. On 5 November 2026, the FBR issued S.R.O. 2063(I)/2026, substituting Rule 160 of the Sales Tax Rules, 2006. From now on, a registered taxpayer who receives an advance payment against a supply must issue an advance receipt invoice at the time the payment is received, and declare the sales tax on that amount in the return for the tax period in which the money came in.
If your business takes deposits, booking amounts, instalments, or part-payments before delivery — and most trading, manufacturing, and service businesses in Pakistan do — this rule touches your everyday paperwork. It does not create a new tax, and it does not tax the same rupee twice. But it does move the moment you have to account for the tax, and it asks for a cleaner paper trail than many small businesses currently keep.
Here is what the rule actually says, what it changes in plain language, and the checks worth doing this week.
What the FBR actually changed
The notification in plain words
According to Profit by Pakistan Today, reporting on 6 November 2026, the FBR has revised the rules governing advance payments against supplies. The change applies to registered taxpayers covered by Section 23 of the Sales Tax Act — the section that sets out who must issue a tax invoice and what it must contain.
The heart of the change is simple. Under the amended Rule 160:
- An invoice at the time of payment. A taxpayer receiving a full or partial advance payment, including payments made in instalments, must issue an advance receipt invoice when each payment is received.
- Tax declared in that period. The sales tax payable on the advance amount must be declared in the return for the tax period in which the payment is received, rather than deferred until the supply is completed.
- One invoice per payment. Where a customer makes multiple advance payments against the same supply, the taxpayer must issue a separate invoice for each payment, and the invoices must be electronically linked so the full record of the transaction stays together.
That last point matters more than it first looks. A customer who pays in three instalments now generates three advance receipt invoices, not one. The FBR wants those three documents linked electronically, so that anyone checking the transaction later can follow it from the first payment to the final invoice without guessing.
The advance receipt invoice counts as a tax invoice
The notification also gives the advance receipt invoice real legal weight. It must contain the particulars prescribed under Section 23 of the Sales Tax Act, and it will be treated as a tax invoice for the purposes of Sections 7 and 8 — the sections that deal with input tax adjustment and the determination of tax liability.
In ordinary language: the advance receipt is not a casual receipt scribbled on a pad. It is a tax document, with the same standing as the invoices your business already issues. That is why the details on it need to be right, and why it needs to be kept and linked with the rest of the transaction’s records.
No double taxation — the safeguard built into the rule
The most common worry with a rule like this is obvious: if I pay tax when the advance arrives, and then pay tax again when I deliver, am I taxed twice on the same money?
The FBR’s answer, as reported, is no — and the notification builds in the mechanism to prevent it. When the goods or services are subsequently supplied, the taxpayer must issue a final sales tax invoice that references the earlier advance receipt invoices. The value and sales tax already accounted for at the advance payment stage will not be included again in the tax calculation. Any additional sales tax will apply only to the remaining value of the supply that has not previously been accounted for.
So a business that takes a 40% advance and later delivers the full order will declare tax on the 40% when the advance arrives, and tax on the remaining 60% when the final invoice is issued. The final invoice must show its working — it references the advance invoices, so the trail is visible. What the rule does not allow is quietly ignoring the advance and declaring everything at the end, or, at the other extreme, paying tax on the same value twice.
The rate that applies is the rate on the day the money arrives
The notification also settles a question that otherwise causes arguments: which tax rate applies when the rate changes between the advance and the delivery?
The sales tax rate applicable to an advance payment will be the rate prevailing when that payment is received. For any outstanding amount, the applicable rate will be determined at the time of supply, in accordance with the Sales Tax Act.
That is a detail worth noting in your records. If a rate changes between the deposit and the delivery, your invoices need to show two different dates and, potentially, two different rates — one for the advance portion, one for the balance. A single blended rate across the whole transaction would not match what the rule asks for.
What happens when things change after the advance
Increases, reductions, refunds, and cancellations
Real business is messier than a textbook example. A customer increases an order after paying a deposit. A price is reduced. A customer asks for a refund. An order is cancelled altogether. The revised rules cover these situations too.
The notification specifies that where advance payments or supply values are subsequently increased, reduced or refunded, or where an order is cancelled in full or in part, the necessary adjustments must be made under Section 9 of the Sales Tax Act and the procedures prescribed in Rules 19 to 22.
In practical terms, that means changes after an advance are handled through debit and credit notes, not by silently rewriting the original invoice. The advance receipt invoice, the related debit or credit notes, and the final sales invoice must all be electronically linked and maintained under the prescribed procedures. The electronic records must allow identification and cross-referencing of all documents associated with a transaction, so the whole story — advance, change, final invoice — can be traced from start to finish.
A small example, worked through
Suppose a furniture maker in Lahore takes a Rs. 200,000 advance on a Rs. 500,000 order. Under the new rule, the maker issues an advance receipt invoice for Rs. 200,000 on the day the money arrives, and declares the sales tax on that Rs. 200,000 in that month’s return.
Two weeks later, the customer adds a side table, raising the total to Rs. 550,000. The additional amount is a change to the supply value, and it is handled through the adjustment procedure — a debit note, linked to the original advance receipt invoice.
When the furniture is delivered, the maker issues a final sales invoice for Rs. 550,000 that references the advance receipt invoice and the debit note. The tax already declared on the Rs. 200,000 advance is not charged again; tax applies only to the remaining Rs. 350,000.
If instead the customer had cancelled, the maker would issue a credit note under the same procedure, and the tax position would be adjusted accordingly.
That is the whole system in miniature: invoice the advance when it arrives, link everything, and settle the balance at delivery without paying twice.
Who this affects most
Businesses that take money before delivery
The rule bites hardest where advance payments are a normal part of doing business. That includes manufacturers who take booking amounts, traders who collect part-payment before dispatch, wholesalers who work on advance orders, and service providers who charge a deposit before starting work. If your business model is “pay first, deliver later” — even partly — your invoicing routine now has an extra step at the front end.
Businesses that were already doing this
Some well-organised businesses were already issuing receipts for advances and declaring the tax in the right period. For them, the change is mostly about form: the receipt must now carry the Section 23 particulars, be treated as a tax invoice, and be electronically linked to the final invoice and any debit or credit notes. The habit is right; the paperwork needs to be tightened.
Businesses that were waiting until delivery
The businesses that need to change most are the ones that treated an advance as a private matter between them and the customer — money in the bank, invoice later. That approach no longer matches the rules. The tax point is now the receipt of the advance, and the return for that period is where the tax belongs.
Five checks to do this week
1. Look at how your business actually takes advances
Before changing any form, look at the real pattern. Which customers pay in advance? Is it a fixed deposit, a percentage, or whatever the customer offers? Are instalments common? The answer shapes how many advance receipt invoices you will be issuing each month, and whether your current billing system can produce them.
2. Make sure your invoice format carries the Section 23 particulars
An advance receipt invoice must contain the particulars prescribed under Section 23 of the Sales Tax Act. If your current receipts are short, handwritten, or missing the details your normal tax invoices carry, bring them up to the same standard. The advance receipt is a tax invoice now, and it will be read like one.
3. Issue one invoice per payment, and link them
If a customer pays in instalments, each payment gets its own advance receipt invoice, and the invoices must be electronically linked. Check whether your accounting or billing software can link documents in a chain — advance receipt, then debit or credit note, then final invoice. If it cannot, that is the gap to close, because a pile of unlinked invoices will not satisfy the traceability requirement.
4. Reconcile the advance in the right return
The tax on an advance belongs in the return for the period in which the payment was received. That means your monthly return routine needs a step that catches advances received during the period, even where no supply has happened yet. A simple monthly list — advances received, advance receipt invoices issued, tax declared — is enough to keep this honest.
5. Keep the rate and the date together
Because the rate that applies is the rate on the day the payment is received, each advance receipt invoice should show its date clearly, and the rate applied should match that date. If a rate changes mid-transaction, the final invoice will need to show the two portions separately. Keeping the date and the rate together on each document avoids a painful reconstruction months later.
A note on keeping the records straight
The rule is, at its heart, a record-keeping rule. The tax itself was always payable; what the FBR wants now is a trail it can follow without asking you to reconstruct it from memory.
What good records look like under this rule
Good records here are not complicated. They are complete, dated, and linked — each document pointing to the next one in the same transaction.
One transaction, one chain
Think of each sale as a chain. The first link is the advance receipt invoice. Every later document — a debit note for an increased order, a credit note for a refund, the final sales invoice — hangs off that first link by reference. If a document does not say which transaction it belongs to, the chain is broken, and that is where problems start.
A simple monthly habit
At the end of each month, before the return is filed, take ten minutes to check the chain. List the advances received that month, match each one to its advance receipt invoice, and confirm the tax on each advance is in that month’s return. It is a small habit, and it is the difference between a business that can answer a question about an old transaction in minutes and one that has to dig through a drawer.
What this rule is not
It is worth saying plainly what has not changed, because tax news travels fast and details get lost on the way.
First, this is not a new tax. The sales tax on the supply was always payable; the change is about when it is declared and how it is documented. Second, it is not double taxation — the notification expressly prevents the same value from being taxed twice. Third, it is not a change to the sales tax rate, which continues to be the rate prevailing when the payment is received, or at the time of supply for the balance.
What it is, is a documentation and timing rule. The FBR wants the money trail visible from the moment an advance arrives, and it wants the documents linked so the trail can be followed. Businesses that already keep clean, linked records will find this a small adjustment. Businesses that have been informal about advances will find it a bigger one — but it is better to make the adjustment now, deliberately, than under a notice later.
Questions business owners are asking
Do I have to issue an invoice for every small advance?
Yes, under the amended Rule 160, a registered taxpayer covered by Section 23 must issue an advance receipt invoice at the time each advance payment is received, including instalments. A separate invoice is required for each payment where a customer pays more than once against the same supply.
Will I pay sales tax twice on the same order?
No. The final sales invoice must reference the earlier advance receipt invoices, and the value and sales tax already accounted for at the advance stage are not included again. Additional tax applies only to the remaining value not previously accounted for.
What if the order is cancelled after I have taken an advance?
The rules cover cancellations in full or in part. Adjustments must be made under Section 9 of the Sales Tax Act and the procedures in Rules 19 to 22 — in practice, through debit or credit notes that are electronically linked to the advance receipt invoice and the final invoice.
Which tax rate applies to my advance?
The rate prevailing when the advance payment is received. For the outstanding balance, the rate is determined at the time of supply under the Sales Tax Act.
Does this apply to unregistered businesses?
The notification, as reported, applies to registered taxpayers covered by Section 23 of the Sales Tax Act. Unregistered businesses have their own obligations under the law, and the wider question of registration is a separate matter — one that the FBR is also pursuing actively, including its phased enforcement drive for retailers under the Asaan Tax Scheme, reported on 4 November 2026.
The bigger picture
This change sits alongside a wider pattern in Pakistan’s tax administration this month: more documentation, more electronic linking, and less room for informal practice. The same week brought the FBR’s phased enforcement drive for unregistered retailers, and the same month brought the 1 November Active Taxpayers List update that removed late filers. Each of those is a separate measure, but they point in the same direction — the tax system is moving towards records that can be checked, linked, and traced.
For a small or medium business, the sensible response is not panic. It is a short, practical review: how do advances flow through your business, do your invoices carry the right particulars, are your documents linked, and does your monthly return catch advances in the right period? Those four questions cover most of what SRO 2063(I)/2026 asks of you.
And if the answer to any of them is “I’m not sure,” that is exactly the moment to ask someone who does this every day — before a return is filed, rather than after a notice arrives.
