Monthly Sales Tax Return Filing — Never Miss the 18th Again
Registration was step one; every month now demands annexures reconciled, payment made by the 15th, and the return e-filed by the 18th — in every regime you're registered with. Our retainer takes that entire cycle off your desk.

How this is verified
Deadlines here follow the official procedure: FBR's published sales-tax schedule sets Annexure C by the 10th, payment by the 15th, and e-filed return by the 18th of the following month, and provincial regimes run the same pattern under their own acts. Rates and rules change through finance bills and SROs — our filings use whatever is current at the time of filing, never memory.
What's actually due every month
The three-date cycle
- • 10th: customer-level sales details (Annexure C) filed
- • 15th: net payable tax deposited via PSID
- • 18th: full return e-filed with purchase/sales annexures
- • Miss one leg and the month counts as non-compliant even if money moved
What the return must reconcile against
- • Output tax vs your sales invoices and banked receipts
- • Input tax vs purchase invoices from registered suppliers
- • Stock movement statements for manufacturing setups
- • Unexplained gaps between these are the most common audit trigger
And the trap most new registrants fall into: months with no business still require a filed nil return. Skipping it feels harmless precisely until inactivation letters and back-penalties arrive.
Same rhythm, different regimes
| Authority | Covers | Return | Payment / filing dates |
|---|---|---|---|
| FBR | GST on goods (federal) | Monthly via IRIS/e-portal | Pay 15th · file 18th |
| PRA | Services originating in Punjab | PST return via e-PRA | Pay 15th · file 18th |
| SRB | Services rendered in Sindh | SST-03 via e-SRB | Pay 15th · file 18th |
Common filing mistakes we prevent
Annexure mismatch
Sales figures that don't tie to Annexure C or bank credits draw system flags. Every figure we file traces to a document first.
Dead input tax
Claims against unregistered or invoice-deficient suppliers get disallowed later — we screen purchases before they enter the return, not after an audit letter.
Missed nil months
Seasonal businesses skip quiet months. Our calendar files nils automatically so your registration stays active year-round.
Wrong-regime boundaries
Businesses straddling goods and services often file income in the wrong regime. Classification review is part of onboarding, not an upsell.
How the monthly retainer runs
- 1
Onboarding & regime audit
We verify exactly which registrations you hold, which apply to your current activity, and whether anything is dormant or duplicated — then fix scope before month one.
- 2
Fixed monthly checklist
A standing document request arrives before month-end: sales register, purchases, bank statement, imports. You forward files; no chasing either direction.
- 3
Preparation & reconciliation
Annexures built, output/input reconciled, net position computed and shown to you before any payment — surprises surface on our desk, not at the deadline.
- 4
Payment by the 15th
PSID generated and paid through your designated channel, receipt archived against the month's file.
- 5
Filing by the 18th + confirmation
Return e-filed in every applicable regime, acknowledgment stored, and a short monthly summary sent: what was filed, what was paid, what changed.
Your standing monthly pack
Every regime
- Sales invoices or register export for the tax period
- Purchase invoices with supplier NTN/STRN visible
- Bank statement for the period
- Prior-month return acknowledgment (we keep this)
Where applicable
- Import GDs and customs documents
- Stock statements (manufacturers)
- Contract notes for works/services supplied
- Utility bills claiming input credit
Retainer pricing philosophy
Government dues — the tax itself and any PSID amounts — are yours at exact official figures. Our retainer is a flat monthly fee set after onboarding, driven only by how many regimes and how much transaction volume genuinely exist.
No per-return surprises in December, no surge pricing when volume spikes. If your business outgrows the quoted tier, we requote transparently at renewal rather than silently billing overages.
Onboarding typically completes within days once access credentials and the first document pack arrive; the first filing follows the normal monthly cycle from there.

Frequently asked questions
What is the due date for the monthly sales tax return?
Under the standard procedure: sales tax details (Annexure C) by the 10th, payment by the 15th, and e-filing of the return by the 18th of the following month. Provincial authorities follow the same rhythm — payment mid-month, return by the 18th.
Do I need to file a sales tax return if I had zero sales?
Yes. A nil return is mandatory every month you remain registered, regardless of activity. Non-filing of a nil return attracts the same consequences as skipping a substantive return — including eventual inactivation of your registration.
What happens if I file my sales tax return late?
Late filing carries penalties that grow with delay and can restrict input tax adjustments; SRB's regime for instance applies escalating fixed penalties within and beyond fifteen days of the due date. Repeated non-filing ultimately renders the registration inactive.
Can you handle both FBR and provincial returns together?
Yes — many businesses owe parallel registrations (federal goods plus provincial services). Our recurring service covers multiple regimes under one engagement, with a single monthly document request instead of three separate chases.
What documents do you need each month?
Typically: sales invoices or a sales register export, purchase invoices with supplier NTN/STRN details, bank statements showing tax-period receipts, and any import documents. We send a fixed checklist every month so nothing gets hunted down at the deadline.
