How to Calculate Income Tax on Salary in Pakistan

Salaried income in Pakistan is taxed using progressive tax slabs that the government announces every year in the federal budget through the Finance Act. Progressive means your income is split into bands, and each band is taxed at its own rate. You do not pay a single flat rate on your whole salary.

Your employer usually deducts this tax at source every month, so your take-home pay is your gross salary minus the monthly tax, along with any provident fund or other agreed deductions. To plan your budget, it helps to know how the monthly deduction is worked out rather than only seeing the final number on your payslip.

Because the exact slab thresholds and rates change from one budget to the next, always confirm the current year's figures on the official Federal Board of Revenue (FBR) website at fbr.gov.pk before you rely on any number. This guide teaches the method so you can apply it to whichever slabs are current.

Follow these steps to estimate your annual tax, then convert it to a monthly figure:

First, work out your annual taxable salary. Multiply your monthly gross salary by twelve, then add bonuses and taxable allowances for the year. Some allowances may be treated differently, so read your salary structure carefully.

Second, find which slabs your annual income falls into for the current tax year on the FBR site. Note the fixed amount for the lower slabs plus the percentage that applies to the portion of income above the slab's starting point.

Third, apply the slab formula. For most slabs the tax is a fixed rupee amount plus a percentage of the income above the slab threshold. Add up the tax across the bands that apply to you.

Fourth, divide the annual tax by twelve to get the approximate monthly deduction. Our salary calculator helps you move between gross, deductions, and net pay, and the percentage calculator is useful for checking each slab's percentage quickly.

Suppose a tax year used these illustrative slabs (these numbers are only to show the method, not real rates, so always check FBR for the real ones): income up to 600,000 rupees a year is taxed at zero, and income between 600,000 and 1,200,000 is taxed at 5 percent of the amount above 600,000.

If your annual taxable salary is 1,000,000 rupees, the first 600,000 is tax free. The remaining 400,000 is taxed at 5 percent, which is 20,000 rupees for the year. Divided by twelve, that is about 1,667 rupees deducted each month.

The same logic scales to higher incomes: you keep adding the fixed amount from lower slabs plus the percentage on the top band. Once you have your annual figure, the savings calculator can help you plan what to do with your after-tax income.

Do not apply the top slab rate to your entire salary. Only the portion inside each band is taxed at that band's rate, so your effective (average) rate is always lower than your highest slab rate.

Do not forget mid-year changes. If you get a raise, a bonus, or change jobs, your annual taxable income changes and your monthly deduction should be recalculated. Keep your payslips so you can reconcile the total at year end.

Do not treat an online estimate as a filed tax return. These calculations help you plan, but your actual liability depends on the current Finance Act, your exemptions, and your full income picture. For anything important, confirm with FBR or a qualified tax adviser.
