Launching a business in Pakistan means stepping into several overlapping tax regimes at once — income tax, sales tax, withholding obligations as an employer, and in some provinces, a service tax on top. None of these are optional add-ons; missing any one of them from day one tends to snowball into penalties long before the founders notice.
Registering the Business Itself
Every entity — sole proprietorship, partnership, or private limited company — needs its own NTN before it can legally invoice or hire. For a company, SECP incorporation typically takes three to five working days, after which the NTN is linked to the CNIC of the principal officer. Registration itself is free through IRIS; the value in using a consultant is mostly speed and avoiding category errors that cause rejections later.
When Sales Tax Registration Kicks In
Once annual taxable supplies pass roughly Rs 10 million, sales tax registration (STRN) becomes mandatory. From that point, the standard rate of 17% applies to most goods, invoices must show the STRN, monthly returns are due, and records need to be kept for at least five years.
Minimum Tax Even on a Loss-Making Year
A young company that shows a loss doesn't automatically escape tax. Under the minimum tax rule, if the normal tax liability comes out below roughly 1.25% of gross turnover, the company still pays that minimum figure — a detail that catches many first-year founders by surprise when they assume a loss year means zero tax.
Building the Right Habits Early
- File the monthly sales tax return by the 18th of the following month, if registered
- File any monthly withholding statement by the 15th
- Pay quarterly advance tax if annual liability is expected to exceed roughly Rs 100,000
- File the annual company return by 31 December (30 September for individuals and AOPs)
- Keep sales and purchase invoices, bank statements, and payroll records for at least five years
Getting these habits in place before the first filing deadline saves founders from the far more expensive process of reconstructing a year's records under notice pressure.
