Sales tax return filing is a mandatory monthly legal requirement. Every registered business, importer, manufacturer, and Tier-1 retailer must file through FBR IRIS before the 28th of each month. A single missed return generates a PKR 10,000 penalty automatically — no warning, no notice. FilerPK files it for you.

Fixed monthly fee · written quote before work begins
Compliance is not a cost — it is a commercial asset your non-filing competitors are handing you for free, every single month.
Under Section 153, filers pay 4% withholding tax on goods sold; non-filers pay 8%. On PKR 5M monthly revenue, that's PKR 200,000 every month — PKR 2.4M a year — retained in your business instead of locked in FBR's system.
Every purchase your business makes carries 18% sales tax. As a registered filer, that tax is fully recoverable against your output liability. Non-registered businesses absorb it as a permanent, unrecoverable cost.
Under PPRA rules, government tender eligibility depends on active ATL status, verified electronically before bids open. One missed return can pull you off the list while compliant competitors move ahead.
Commercial banks verify ATL status before approving working capital loans, import LCs, and trade finance facilities under SBP regulations. Active filers receive preferential terms; non-filers face rejection or punitive pricing.
Filers pay 3% withholding on property sales under Section 236C; non-filers pay 6%. On a PKR 30M transaction, that's PKR 900,000 saved — for nothing more than keeping your monthly return current.
Regular compliant filings build a documented history that protects you in FBR audits. Gaps in your filing record are the single biggest trigger for best-judgment assessments and extended audit windows.
Mandatory registration and mandatory monthly filing apply to the following categories. If you fall into any of these, non-filing is not an option — it is a penalty waiting to happen.
Voluntary Registration: Turnover below PKR 10 million? You can still register voluntarily. It places your business on FBR's Active Taxpayers List immediately — cutting your withholding tax rates in half and unlocking input tax credits your unregistered competitors cannot claim.
Whether you are a manufacturer, exporter, importer, freelancer, or registered retailer, the filing profile is different. FilerPK applies the correct Annexure combination for your business type not a generic template.
Annexure A + C
Local Purchase & Sales
Standard monthly return for businesses making and receiving local taxable supplies. Annexure A captures purchases with supplier STRNs; Annexure C records all sales with buyer STRNs for automatic IRIS matching.
Annexure B
Import-Based Returns
Importers of taxable goods file Annexure B to claim input tax on customs-cleared imports. Every import entry must match your GD (Goods Declaration) number — mismatches generate automatic disallowances.
Annexure E
Export & Zero-Rated Returns
Commercial exporters and zero-rated suppliers under Schedule 5 file Annexure E. Refund claims under the Expeditious Refund System (ERS) are initiated from this Annexure — accuracy here directly impacts your cash flow.
Annexure F
Withholding Agent Returns
Withholding agents — companies and registered persons deducting sales tax from supplier payments — must file Annexure F. Missing this creates a compliance gap that triggers FBR audit selection.
Annexure D
Debit & Credit Note Filing
Returns of goods, price adjustments, and post-supply corrections are reported through Annexure D. Timing rules apply — debit/credit notes must be issued within 180 days of the original supply.
Amended Return
Amended & Annual Returns
Corrections to a filed return are permitted within 120 days under Section 26(3) without Commissioner approval. The annual return, due 30 September, reconciles all twelve monthly returns against audited accounts.

| Quarterly (Jan–Mar) | 28 April | PKR 10,000 per missed month |
| Annual Return | 30 September | Separate penalty under Sec 33 |
Beyond the fixed penalty, late filing triggers a default surcharge on any unpaid tax at KIBOR + 3% per annum. With KIBOR between 15% and 22%, that surcharge runs at 18–25% annually on every rupee of unpaid tax.
Your position on FBR's Active Taxpayers List — determined entirely by whether your monthly return is current — sets which column applies to every payment you send and receive.
| Transaction | Section | Filer Rate | Non-Filer Rate |
|---|---|---|---|
| Sale of goods — company | 153(1)(a) | 4% | 8% |
| Sale of goods — individual | 153(1)(a) | 4.5% | 9% |
| Services — company | 153(1)(b) | 8% | 16% |
| Contracts — company | 153(1)(c) | 7% | 14% |
| Property sale | 236C | 3% | 6% |
| Bank profit on debt | 151 | 15% | 30% |
| Dividend income | 150 | 15% | 30% |
The ATL refreshes quarterly. One missed return can pull you off the list — reinstatement carries its own procedural cost and a PKR 1,000 surcharge.
Real feedback from individuals and businesses we've registered across Pakistan — this is the trust signal Google's 2026 local updates weight most heavily, and it's currently missing from the live page.
"We had three months of missed returns and were facing PKR 30,000 in penalties. FilerPK filed all three, handled the penalty application, and set up ongoing monthly filing. Haven't missed a deadline since."

"As an Amazon FBA seller I had no idea I needed a sales tax registration. FilerPK got my STRN in 72 hours, filed back-months, and now handles everything monthly. My WHT on bank withdrawals dropped immediately."
UA
"FilerPK recovered 15% additional input tax in my first quarter that I had been writing off as a cost for two years. Their review of my Annex-A alone paid for three years of their fee."

Client Reviews
Most compliance failures are not from dishonesty — they are from not knowing what IRIS expects, and what it silently disallows.
01
Wrong or Missing STRNs on Invoices
IRIS automatically disqualifies input tax claims where the supplier STRN is missing, incorrect, or belongs to a deregistered taxpayer. Most DIY filers only discover this when a mismatch notice arrives — months later, after the 120-day amendment window has closed.
02
Filing Late or Missing the PSID Step
A return submitted without a valid PSID payment confirmation is not a complete return. IRIS timestamps both steps independently. Many businesses believe they have filed when only the return — not the payment — was submitted. The penalty generates on the 29th regardless.
03
Ignoring the Annual Reconciliation
Businesses that file monthly but ignore the annual return leave a three-year audit window open. FBR uses the annual reconciliation to identify discrepancies between monthly returns and audited accounts. The notice arrives years later — with accumulated interest and formal proceedings.
There is a widespread misconception that income earned abroad or through international platforms escapes Pakistani tax law. It does not. All income earned by a Pakistan-resident, from any source, is taxable in Pakistan.
Section 154 — 1% Final Tax
Amazon FBA Sellers
FBR tracks Amazon FBA remittances through SBP and banking data. Sellers must report export income, apply the 1% final tax under Section 154, and file monthly to maintain ATL status and filer WHT benefits. FilerPK handles this end-to-end.
Payoneer · Wise · Bank Transfer
Freelancers & Digital Exporters
Freelancers remitting through Payoneer, Wise, or direct bank transfer face the same reporting obligation. Our freelancer package from PKR 3,500/month covers monthly return, ATL maintenance, and annual income tax return preparation.

Why FilerPK
We serve clients in person from Bahawalpur and online across Pakistan. Here is the specific case for choosing us.
Every return FilerPK submits is prepared by a qualified accountant or tax lawyer — someone who reads the Sales Tax Act, tracks SROs, and catches input tax disallowances before they become mismatch notices. Your return is a legal statement to FBR. It is treated accordingly.
We file by the 27th. Our internal calendar tracks every client's tax period, collects data proactively, and processes submissions ahead of deadline. Not a single client deadline has been missed since operations began — that is a track record, not a claim.
When clients receive FBR notices, audit intimations, or mismatch claims, our tax advisors handle the response, prepare supporting evidence, and represent them before the Commissioner of Inland Revenue. Resolved across Lahore, Karachi, and Islamabad.
Most businesses claim only the obvious credits. FilerPK's review identifies every admissible offset including provincial cross-credits (SRB, PRA, KPRA, BRA) and import duty adjustments. Across our portfolio, this recovers 12–18% additional input tax per quarter.
Every sales tax return is reviewed by a qualified professional — not processed by a form.

FBR IRIS operates online — your city does not limit the process. But local sector knowledge does. Here is what makes each market different.
Primary Office
Bahawalpur
FilerPK's home office. We know the RTO, the local market, and the compliance gaps Bahawalpur SMEs face — particularly first-time registration, missed return penalties, and input tax recovery for wholesale and cotton trading businesses.
Lahore
Active POS integration drives since 2023 in Gulberg, MM Alam Road, and DHA. The Finance Act 2025-26 expanded enforcement powers in Lahore's commercial zones. Monthly Annex-C and Annex-F reconciliation is non-negotiable here.
Karachi
Three FBR offices — LTO, RTO-I, and RTO-II — cover Pakistan's highest-volume import and trading economy. Importers filing Annex-B and large manufacturers under LTO jurisdiction face the strictest audit scrutiny in the country.
Multan
Cotton ginning, food processing, and agricultural supply chains generate substantial obligations — especially for dealers buying from unregistered farmers. Input tax admissibility on agri-supply purchases requires precise documentation under current SROs.
Faisalabad
Pakistan's largest textile economy. Manufacturers, yarn traders, and garment exporters carry the highest monthly sales tax volumes in Punjab. Input tax refund claims through FBR's Expeditious Refund System form a critical part of cash flow here.
All Other Cities
Rawalpindi, Peshawar, Quetta, Sialkot, Gujranwala, Hyderabad — served entirely via WhatsApp and our secure portal. Same documentation standard and review process as in-person clients, delivered digitally.
FAQs
The standard deadline is the 28th of the month following the tax period. FBR's guidance also references the 18th in some standard timelines, and due dates are frequently extended by SRO notification. FilerPK tracks every update and files by the 27th regardless.
IRIS generates an automatic PKR 10,000 penalty with no warning on the 29th, plus a default surcharge on any unpaid tax at KIBOR + 3% per annum. Repeated non-filing can also trigger a Best Judgment Assessment under Section 11 of the Sales Tax Act.
Registration is mandatory above PKR 10 million turnover, but voluntary registration below that threshold puts you on the Active Taxpayers List immediately — halving your withholding tax and unlocking input tax credit your unregistered competitors cannot claim.
Yes, where domestic supplies or taxable income apply. FBR tracks remittances through SBP and banking data. FilerPK handles the 1% final tax under Section 154 and monthly filing to maintain ATL status and filer WHT benefits.
The standard rate under the Sales Tax Act, 1990 is generally 18%, though reduced, zero-rated, exempt, and higher rates apply to specific goods and sectors through Schedules and SROs issued by FBR. The applicable rate depends on your industry and supply type.
Yes — within 120 days of the original filing under Section 26(3) of the Sales Tax Act, without Commissioner approval. Beyond 120 days, formal permission is required. FilerPK includes amendments for data errors within this window at no extra charge.
Yes. Notice handling is available for returns filed with FilerPK and as a standalone service for returns filed elsewhere. Our tax advisors prepare responses, supporting evidence, and represent clients before the Commissioner of Inland Revenue for mismatches, disallowances, and Best Judgment cases.
The annual sales tax return is due by 30 September of the following tax year. It reconciles twelve months of monthly returns against audited accounts. FBR uses it to flag discrepancies and can exercise a three-year audit window retroactively. Most businesses ignore it — and pay for it years later.
