Your payslip is monthly, but the tax is annual
The detail that confuses almost every salaried person in Pakistan is this: income tax is assessed on your annual income, yet it is deducted from each monthly salary. Your employer is required under section 149 of the Income Tax Ordinance to withhold tax at source every month and deposit it with the Federal Board of Revenue (FBR). To do that, they take your annual figure, work out the year's tax under the slabs, and slice it into twelve. This calculator mirrors that exact process so you can check the deduction on your own payslip rather than taking it on faith.
Pakistan rewrites its salary slabs in most years through the Finance Act, so the bands and rates shift annually. The structure is stable and worth learning; the precise numbers are not. Everything below is the rate this calculator applies for the modelled year, and you should confirm the live slabs with the FBR before treating any figure as final.
Tracing a PKR 200,000 monthly salary through the year
Take the tool's default of PKR 200,000 a month. The first move is to annualise: twelve months gives PKR 2.4 million of taxable salary. The slabs are then applied to that annual figure. Using the rates this calculator applies, the first PKR 600,000 is tax-free, the next PKR 600,000 up to PKR 1.2 million is taxed at 1%, the PKR 1.2 million to 2.2 million band at 11%, and the final slice from PKR 2.2 million to 2.4 million at 23%. Add those up and the annual tax is PKR 162,000. Divide by twelve and your employer withholds PKR 13,500 a month, leaving a monthly net of PKR 186,500.
| Stage | Working | Amount |
|---|
The chart splits the PKR 200,000 monthly salary into the slim PKR 13,500 the FBR takes and the PKR 186,500 you keep. On this salary the take-home block dwarfs the tax block, which surprises people who assume a higher slab means a heavy monthly hit.
Where the monthly figure can mislead you
The neat divide-by-twelve assumes a steady salary all year. Real working life is messier. A bonus, a mid-year raise, arrears, or a job change part-way through the year all change your annual total, and the monthly deduction your employer applies will adjust to keep the year on track. That is why a bonus month can show a deduction far larger than usual: the system is catching up the annual tax in one go. This calculator models a level salary, so use it as a baseline and expect real payslips to wobble around it.
One thing to watch at the very top end: this tool adds the high-income surcharge of 9% of tax payable that the FBR applies once annual taxable income passes PKR 10 million, as modelled here. For a PKR 200,000-a-month salary that surcharge is nowhere near being triggered, but a senior executive on a much larger package will see it lift both the annual and the monthly figure.
Reading this against your actual payslip
This calculator is for salaried employees who want to sanity-check the tax line on their slip, and for anyone weighing a job offer quoted as a monthly gross who needs the real monthly take-home. A practical tip: enter your gross salary, the figure before any deductions, not your net, or the tool will understate the tax. If your payslip also shows provident fund or EOBI deductions, those are separate from income tax and will not appear here, so your true take-home may be a little lower than the net pay shown.
My employer deducted more this month than the calculator shows. Why?
The usual cause is a bonus, arrears, or a raise that pushed your annualised income up, so the employer recalculated the year's tax and recovered the extra in that month's deduction. Allowances treated as taxable can do the same. Over the full year the totals should reconcile. If the gap looks wrong, ask your payroll team for the annual computation they are using.
Is the monthly tax deducted the same as my final tax for the year?
For a straightforward salaried employee with one employer and no other income, the monthly deductions usually add up to your full annual liability, and you may not owe more at filing. But if you have rental income, profit on savings, or capital gains, those are taxed separately and your annual return can show additional tax beyond what was withheld monthly. Always file to reconcile the position with the FBR.
