Sales Tax Registration Complete Step-by-Step Guide
Sales tax registration is a legal requirement for businesses involved in taxable supplies in Pakistan. The Federal Board of Revenue (FBR) has made this process fully online through the IRIS portal, allowing individuals and companies to register for sales tax without visiting tax offices. This guide explains what sales tax registration is, who needs it, required documents, and how to register using the IRIS portal, all in a clear and practical way.
What Is Sales Tax Registration?
Sales tax registration is the process of enrolling a business with FBR so it can legally charge, collect, and deposit sales tax on taxable goods or services. Once registered, the business receives a Sales Tax Registration Number (STRN) and becomes an active taxpayer.
Sales tax registration is different from income tax registration. A business must be income tax registered first before applying for sales tax registration on the IRIS portal.
Who Needs Sales Tax Registration in Pakistan?
Sales tax registration is mandatory for:
- Manufacturers of taxable goods
- Importers and exporters
- Wholesalers, distributors, and retailers (where applicable)
- Service providers covered under federal or provincial sales tax laws
- Online sellers and e-commerce businesses
- Businesses exceeding the prescribed turnover threshold
Failure to register when required can result in penalties, audits, and business restrictions.
Benefits of Sales Tax Registration
Registering for sales tax through the IRIS portal provides multiple advantages:
- Legal authority to charge sales tax
- Ability to issue valid tax invoices
- Claim input tax adjustments
