Income Tax for Sole Proprietors and Partnerships in Pakistan

If you run a shop, a small trading business, a consultancy, or any operation that isn't formally incorporated as a company, you're most likely taxed as a "business individual" or, if you have partners, as an Association of Persons (AOP) — and the rules are meaningfully different from salaried tax.

Different slabs, not just different rates

Business individuals and AOPs follow a separate slab structure from salaried employees under the 2025-26 rates — generally with a steeper rate progression at lower income levels compared to salaried slabs. The same Rs 600,000 tax-free threshold applies, but the rates climb faster from there. Run your expected annual profit through our income tax calculator and select "Business / AOP" to see your actual slab and rate.

What counts as taxable business income

Your taxable income is your business profit — revenue minus allowable business expenses — not your gross sales. Keeping clean records of your actual costs (rent, utilities, salaries paid, inventory, supplier payments) directly reduces your taxable profit, so basic bookkeeping isn't just good practice, it's a genuine tax reduction tool.

Withholding tax you'll encounter as a business

• Payments you receive under contracts are often subject to withholding under Section 153, deducted by your client before payment
• Payments you make to suppliers or service providers may require you to withhold tax and deposit it with FBR
• If you import goods, withholding tax applies at the point of clearance under Section 148

Our withholding tax calculator covers all of these categories with current filer, late filer, and non-filer rates.

Sales tax registration threshold

Depending on your business type and turnover, you may also need to register for sales tax separately from income tax. Retailers and service providers above certain turnover thresholds are required to register with FBR or the relevant provincial revenue authority.

Registering your business properly

Sole proprietorships don't require formal incorporation, but you should still register for an NTN specific to your business activity through FBR's IRIS portal. Partnerships should have a registered partnership deed and, ideally, registration with the relevant provincial authority, before applying for a business NTN.

Don't skip advance tax

Business individuals and AOPs above certain income levels are required to pay advance tax quarterly, based on estimated annual income, rather than paying the full amount at year-end. Missing quarterly advance tax payments can trigger additional charges even if your final annual return is filed correctly.
