Published: June 25, 2026 · 7 min read

If you are starting a new business in Pakistan that will sell taxable goods or services, registration for sales tax with FBR is mandatory once your annual turnover crosses the threshold. Under the Sales Tax Act 1990, the registration threshold for goods-suppliers is Rs 10 million in annual turnover (for manufacturers and importers) and Rs 5 million for retailers; for service-providers, registration is required regardless of turnover from the day you start providing the service. The registration process has moved entirely online via the FBR IRIS portal, and once registered, your business receives a Sales Tax Registration Number (STRN) that must appear on every tax invoice, every return, and every sales-tax-related document.

Headline: sales tax registration is fully online via iris.fbr.gov.pk. Registration typically takes 30-90 minutes to complete the application and 7-14 working days for FBR to issue the STRN. There is no registration fee, but you need NTN first, a CNIC-verified IRIS account, and active bank account in the business name.

Who must register for sales tax

Sales tax registration is required in Pakistan under the following conditions:

Business type	Registration threshold (annual turnover)
Manufacturer	Rs 10 million
Importer	Rs 10 million
Wholesaler / distributor	Rs 10 million
Retailer	Rs 5 million (mandatory from this threshold)
Service provider	Any turnover from day one
Exporter	Mandatory from day one (for refund eligibility)
Restaurant / catering	Rs 5 million

Rs 10MManufacturer/importer turnover threshold

Rs 5MRetailer turnover threshold

0Service-provider threshold (any turnover)

18%Standard sales tax rate (most goods)

The voluntary registration rule. Even if your turnover is below the mandatory threshold, you can register voluntarily. Voluntary registration is often useful for businesses that want to issue proper tax invoices (required by many B2B customers), claim input tax credit, or appear compliant from day one. The application is the same.

What you need before applying

Sales tax registration requires three pre-requisites that must already be in place:

National Tax Number (NTN) for the business — if you don’t have an NTN yet, register for income tax first. Sole proprietors use their personal CNIC + NTN; partnerships and companies need a separate business NTN.
Active IRIS account — your CNIC-linked account on iris.fbr.gov.pk. If you’ve filed a personal income tax return before, your IRIS account exists.
Active bank account in the business name — sole proprietors can use a personal account; companies must use a corporate account.

Additional documents you’ll need for the application:

CNIC of all owners / partners / directors (front + back scans)
Business registration certificate (if partnership or company) from SECP
Memorandum of Association + Articles of Association (for companies)
Partnership deed (for partnerships)
Business address proof (utility bill, rent agreement, or property ownership)
Bank account statement or cancelled cheque in the business name
Nature of business declaration (what you sell, expected turnover)
Premises photograph (front of business location)

How to register — step by step

The entire process runs through IRIS:

Log in to iris.fbr.gov.pk with your CNIC and IRIS password
Navigate to “Registration” in the left sidebar
Select “Sales Tax Registration” from the available options
Choose the appropriate registration type (Individual, AOP, Company)
Fill in business details: legal name, trade name (if different), NTN, business address, principal business activity, business start date
Enter business bank account details (account number, bank name, branch code)
Upload the required documents: CNIC scans, business registration, address proof, bank statement, premises photo
Provide details of business premises: ownership status (owned / rented), area, type (shop / office / warehouse / factory)
Declare expected annual turnover, expected monthly sales-tax liability, expected monthly purchases
Declare any sister-concern businesses (related entities)
Add proprietor / partner / director details with CNIC numbers
Review the application and digitally sign
Submit the application — you’ll receive an application tracking ID

FBR then reviews your application. The review process has two stages:

Stage	What happens	Typical time
Auto-verification	System checks CNIC, NTN, business registration, bank account	Immediate to 24 hours
Officer review	FBR officer reviews uploaded documents; may request clarification	7-14 working days

Once approved, you receive the STRN. Your Sales Tax Registration Number is a 7-digit number (e.g., 1234567) issued by FBR. It must appear on every tax invoice your business issues, on every sales tax return (STR) you file, and on every sales-tax-related correspondence. Without an active STRN, you cannot issue valid tax invoices or claim input tax credit.

What happens after registration

Once your STRN is issued, you have ongoing obligations:

Monthly or quarterly sales tax return — to be filed via IRIS, due by the 18th of the following month (for monthly filers) or 18th of the month following the quarter (for quarterly filers)
Tax invoicing — every sale must be supported by a sales tax invoice showing STRN, item description, sales tax amount, and customer’s NTN if B2B
Input tax credit tracking — claim credit for sales tax paid on business purchases (subject to SRO restrictions)
Withholding tax compliance — certain B2B transactions require withholding under Sales Tax Withholding (STW) provisions
Annual sales tax return — annual reconciliation in addition to monthly/quarterly returns
Record keeping — invoices, purchase records, and bank statements for 6 years minimum

The two filing frequencies

Filer selection between monthly and quarterly depends on turnover:

Monthly filers: Required if your annual turnover is above Rs 50 million, or if your business involves zero-rated supplies (exports), or if you are in specific high-volume categories
Quarterly filers: Default for most small and medium businesses with turnover below Rs 50 million; you file once every three months

Both categories have similar application processes, but monthly filers have stricter documentation requirements.

Common rejection reasons and how to fix them

Rejection reason	Fix
CNIC information mismatch	Verify CNIC at NADRA; ensure mobile number and address match IRIS
Business address unverifiable	Provide clearer utility bill or rent agreement; ensure address is verifiable on Google Maps
Bank account not in business name	Open a separate bank account in the business name (sole proprietors can use personal account)
Business activity unclear	Provide clearer description of what you sell; reference specific PCT/HS codes if applicable
Premises photograph not provided	Upload a clear photo of the front of your business location
Documents expired or low-quality scans	Re-scan at 300 DPI minimum; ensure all pages of multi-page documents are uploaded

Special cases that need extra steps

Some business categories require additional registrations or have specific rules:

Service providers

If you provide services, you may also need provincial sales tax registration (Punjab, Sindh, KP, Balochistan have provincial sales tax on services). FBR handles federal sales tax; the Punjab Revenue Authority (PRA), Sindh Revenue Board (SRB), KPRA, and BRA handle provincial. You may need both.

Exporters

Exporters register for sales tax to claim refunds on the input tax paid. The refund process is separate and requires additional documentation including bank realisation certificates, GD (Goods Declaration) numbers, and commercial invoices.

Manufacturers

Manufacturers must provide factory layout, machinery list, and energy connection details. The registration review is more rigorous and often includes an on-site inspection.

E-commerce sellers

Online sellers (Daraz, Shopify, etc.) must register for sales tax regardless of turnover from the first sale. FBR has specific guidance for digital sellers and platforms; cross-border digital services are subject to additional rules under Section 8 of the Sales Tax Act.

The broader tax-compliance picture. Sales tax registration is one piece of the compliance stack. A new business also typically needs: (1) NTN registration with FBR; (2) provincial sales tax registration if applicable; (3) professional tax registration with the provincial revenue authority; (4) SECP company registration if a company; (5) Punjab Employees Social Security Institution (PESSI) / Sindh Employees Social Security Institution (SESSI) registration if you have employees; (6) EOBI registration. Many of these are now also digital.

Frequently asked questions

How long does sales tax registration take from application to STRN issue?For straightforward cases (sole proprietor with clear documents), 7-14 working days. For companies and manufacturers with complex structures, 30-60 days including potential site inspection.

Is there a fee for sales tax registration?No, the application is free. FBR does not charge for the STRN itself.

Can I register for sales tax without NTN?No — you must have an active NTN before applying for sales tax registration. If you don’t have NTN, the IRIS system prompts you to file an income tax return first, which generates your NTN.

What if my business is a freelance / consulting activity with no goods?You still need to register if you’re a service provider. Service providers register under “Sales Tax on Services” with the appropriate provincial authority (PRA, SRB, KPRA, BRA) and may need FBR registration depending on the service type.

Can I deregister if my business closes?Yes — apply for cancellation via IRIS. You’ll need to file final returns, pay any outstanding sales tax, and provide closure documentation. FBR may conduct a final audit.

What is the penalty for not registering when required?Operating without STRN while above the threshold is a punishable offence under Section 33 of the Sales Tax Act. Penalty: Rs 25,000 or 3% of the value of supplies, whichever is higher. Repeat offences can lead to criminal prosecution.

Do I need separate STRN for multiple businesses?Each separate business entity requires its own STRN. If you operate multiple businesses under the same CNIC, you can register each as a separate “registration” under the same NTN.

What happens to my STRN if I change business address?Update via IRIS within 30 days. Failure to update address is a punishable offence and can lead to STRN suspension.
