If you run a business in Pakistan — whether you're a manufacturer, importer, retailer, or service provider — sales tax registration is not optional. It's a legal requirement under the Sales Tax Act 1990, and skipping it can cost you heavy penalties from the Federal Board of Revenue (FBR).

The good news? The entire process is now online through the FBR IRIS portal, and with the right guidance, you can complete your sales tax registration in Pakistan without visiting any office.

This guide walks you through everything — from who needs to register, to the exact steps on the IRIS portal, to what happens after registration.

What Is Sales Tax Registration in Pakistan?

Sales tax registration is the process through which a business or individual gets officially enrolled as a sales taxpayer with the Federal Board of Revenue (FBR). Once registered, you receive a Sales Tax Registration Number (STRN) — also called a GSTIN or GST number in Pakistan — which allows you to legally collect sales tax from customers, issue tax invoices, and file monthly sales tax returns.

Under the Sales Tax Act 1990, the standard sales tax rate in Pakistan is 18% on most goods, with reduced rates, zero-rating, and exemptions applying to specific categories like medicines, basic food items, and exported goods.

Sales tax registration in Pakistan is a mandatory process for eligible businesses to register with FBR and obtain a STRN number, enabling them to collect, file, and pay sales tax under the Sales Tax Act 1990.

Who Needs to Register for Sales Tax in Pakistan?

Not every business is required to register, but the following categories must register for sales tax:

• Manufacturers producing taxable goods
• Importers of taxable goods
• Exporters dealing in zero-rated supplies
• Distributors and wholesalers dealing in taxable goods
• Retailers classified as Tier-1 (those integrated with FBR's Point of Sale system)
• Service providers registered under provincial authorities (SRB in Sindh, PRA in Punjab, KPRA in KPK, BRA in Balochistan)
• Any person whose annual turnover exceeds the threshold set by FBR

Freelancers and salaried individuals are generally not required to register for federal sales tax unless they provide taxable services or goods. If you're unsure about your status, reading ICT's guide on how to become a filer in Pakistan is a great starting point.

Difference Between NTN and STRN

Many people confuse these two numbers, so let's clear it up simply:

You need an active NTN before you can apply for sales tax registration. If you haven't registered for NTN yet, visit ICT's complete NTN guide to get started.

Documents Required for Sales Tax Registration in Pakistan

Before you log into the FBR IRIS portal, make sure you have these documents ready:

• CNIC (for sole proprietors or individuals)
• NTN number (already registered on IRIS)
• Business address proof (utility bill or rent agreement)
• Bank account number (active business bank account)
• Business registration certificate (for companies and AOPs)
• Mobile number and email linked to your FBR account
• Electricity bill of business premises
• Memorandum and Articles of Association (for companies only)

Step-by-Step Sales Tax Registration Process on FBR IRIS Portal (2026)

Here is the complete, updated process for online sales tax registration via FBR IRIS in 2026:

Step 1: Visit the FBR IRIS Portal

Go to the official FBR IRIS portal at iris.fbr.gov.pk. This is Pakistan's centralized e-filing system for all tax registrations and returns.

Step 2: Log Into Your IRIS Account

Enter your NTN number and password to log in. If you have forgotten your password, use the "Forgot Password" option which sends a PIN to your registered mobile number.

Don't have an IRIS account yet? You'll need to complete e-enrollment first by registering your CNIC, mobile number, and email through the portal.

Step 3: Navigate to Registration Section

Once logged in, go to the "Registration" section in the left menu. Click on "Sales Tax Registration" or look for "Form STR-1" — the official sales tax registration form.

Step 4: Fill Out the Sales Tax Registration Form

Complete the form with accurate details including:

• Business name and type (sole proprietor, company, AOP)
• Business address
• Principal activity (manufacturing, trading, services)
• Bank account details
• Contact information

Make sure every detail matches your CNIC and NTN records exactly. Mismatches are the most common reason for application rejection.

Step 5: Upload Required Documents

Upload scanned copies of all required documents in the specified formats (PDF or JPEG). The portal will prompt you for each document category.

Step 6: Submit the Application

After reviewing your form, click "Submit". The system will generate a tracking number — save this for future reference.

Step 7: Verification and Approval

FBR typically processes sales tax registration applications within 3 to 7 working days. You may receive a verification visit from a local tax officer, especially for manufacturing businesses.

Step 8: Download Your Sales Tax Certificate

Once approved, log back into your IRIS account and download your Sales Tax Registration Certificate. This certificate contains your official STRN number.

Congratulations — you are now a registered sales taxpayer in Pakistan!

What Happens After Sales Tax Registration?

Registration is just the beginning. Here's what you're now required to do:

File Monthly Sales Tax Returns Every registered person must file a sales tax return by the 15th of each following month on the FBR IRIS portal. This includes declaring output tax (tax collected from customers) and input tax (tax paid on purchases).

Issue Proper Tax Invoices All your sales invoices must now follow the sales tax invoice format prescribed under the Sales Tax Rules 2006. The invoice must include your STRN, the buyer's details, tax amount, and description of goods/services.

Maintain Tax Records Keep all purchase and sales records for at least 5 years. FBR can conduct a sales tax audit at any time.

Integration with FBR's Point of Sale System If you are a Tier-1 retailer, you must integrate your billing system with FBR's POS network. This is mandatory and non-negotiable.

How to Register for Sales Tax in Pakistan

Provincial Sales Tax vs Federal Sales Tax — What's the Difference?

This is a question many business owners in Pakistan ask, and rightly so.

Federal Sales Tax (administered by FBR) applies to goods and applies uniformly across Pakistan. Provincial Sales Tax applies to services and is administered by four separate revenue authorities:

• SRB — Sindh Revenue Board (Karachi and Sindh)
• PRA — Punjab Revenue Authority (Lahore and Punjab)
• KPRA — Khyber Pakhtunkhwa Revenue Authority (Peshawar and KPK)
• BRA — Balochistan Revenue Authority (Quetta and Balochistan)

If your business provides services, you may need to register with your provincial revenue authority instead of — or in addition to — FBR. For example, a software company in Lahore would register with PRA, while a consulting firm in Karachi would register with SRB.

Sales Tax Registration by City — Local FBR Offices

Islamabad: FBR's headquarters is in Islamabad. You can visit the FBR Regional Tax Office (RTO) in Islamabad for in-person assistance, or complete the process entirely online via IRIS.

Lahore: Businesses in Lahore dealing in services register with PRA (Punjab Revenue Authority) for provincial services tax, while goods-based businesses register with FBR's Lahore RTO.

Karachi: Service providers in Karachi register with SRB (Sindh Revenue Board). Manufacturers and importers register with FBR's Large Taxpayer Office or RTO Karachi.

Peshawar, Faisalabad, Multan, Sialkot, Rawalpindi: All cities have regional FBR offices. However, the IRIS portal makes it possible to complete registration from anywhere in Pakistan without visiting an office.

Penalties for Not Registering for Sales Tax

Ignoring sales tax registration is a costly mistake. Under Pakistani tax law, FBR can impose:

• Fines up to PKR 25,000 for failure to register
• Additional penalties equal to the unpaid tax amount
• Criminal prosecution in serious cases of tax evasion
• Blacklisting of your business from the Active Taxpayer List
• Seizure of goods in case of significant violations

FBR has significantly increased audit activity in 2026, using AI-powered tools to detect unregistered businesses with high turnovers. Learn more about FBR's digital transformation in Pakistan and why compliance now matters more than ever.

How to Check Sales Tax Registration Status

You can verify any business's sales tax registration status on the FBR portal:

1. Visit fbr.gov.pk or iris.fbr.gov.pk
2. Go to "Online Verification"
3. Enter the STRN or NTN number
4. The system will show the registration status instantly

This is especially useful when dealing with suppliers — always verify their STRN before accepting a tax invoice.
