Income Tax Calculator Pakistan 2025-26: What Salary Tax Really Costs Each Month
An income tax calculator Pakistan 2025-26 answers the question every salaried worker in Pakistan asks when a new budget lands: how much of my salary will tax take this year, and what lands in my account each month? It takes a monthly or annual salary, applies the Federal Board of Revenue's salaried slabs for Tax Year 2025-26 under the Finance Act 2025, and returns the yearly tax, the monthly deduction, and the take-home pay. The slabs changed in this budget, so a calculator still running last year's rates will give you a wrong answer with total confidence.
The most important idea in the whole guide is also the most misunderstood: Pakistan taxes salary in slices, not all at once. Only the slice of income inside each slab is taxed at that slab's rate. A worker whose income reaches the 30% slab does not pay 30% on the full salary, and the gap between the top rate and the real rate is often tens of thousands of rupees a month.
The 2025-26 salaried slabs, slice by slice
The table below is the full slab structure the calculator uses. Each row taxes only the income inside that row's range, and the fixed amounts in the right column are just the tax from all the rows below, added up for convenience.
| Annual taxable income | Tax |
|---|---|
| Up to Rs 600,000 | 0% |
| Rs 600,001 to 1,200,000 | 1% of the amount exceeding Rs 600,000 |
| Rs 1,200,001 to 2,200,000 | Rs 6,000 + 11% of the amount exceeding Rs 1,200,000 |
| Rs 2,200,001 to 3,200,000 | Rs 116,000 + 23% of the amount exceeding Rs 2,200,000 |
| Rs 3,200,001 to 4,100,000 | Rs 346,000 + 30% of the amount exceeding Rs 3,200,000 |
| Above Rs 4,100,000 | Rs 616,000 + 35% of the amount exceeding Rs 4,100,000 |
One more layer sits on top for very high earners. If taxable income passes Rs 10,000,000, a 9% surcharge applies to the tax itself, not to the income. That distinction matters: on a tax bill of Rs 3,381,000 the surcharge adds Rs 304,290, which is 9% of the tax, not 9% of the salary. Below Rs 10,000,000 there is no surcharge at all for salaried workers.
The 2025 budget also cut rates in the middle slabs, which is why old calculators overstate today's tax. The second slab fell from 5% to 1%, the third from 15% to 11%, and the fourth from 25% to 23%. A worker earning Rs 1,200,000 a year paid Rs 30,000 under the old second slab rate and pays Rs 6,000 now. If a site still shows the old rates, its answers belong to last year.
Every input, explained
Monthly salary. Your gross monthly salary in rupees, before tax and before any deduction. The calculator multiplies it by 12 to get the annual figure the slabs apply to. Annual salary. The same figure stated yearly. The two boxes stay in sync: type in one and the other follows, so enter whichever one your offer letter or payslip shows and let the tool handle the conversion.
What the calculator treats as income is your taxable salary for the year. In real life, taxable income can differ from gross salary because of allowances, exemptions, and deductions your employer applies before withholding. The calculator shows the slab math on the figure you enter, so if your payslip's taxable income differs from your gross salary, enter the taxable figure for the closest match to your actual deduction.
A worked example: Rs 100,000 a month, slab by slab
A salaried worker earns Rs 100,000 a month, which is Rs 1,200,000 a year. Walking through the slabs one at a time shows exactly where the tax comes from, and why it is so small at this income.
- First Rs 600,000: tax Rs 0. The first slab is tax free, so the first half of this salary escapes tax entirely.
- Next Rs 600,000 at 1%: tax Rs 6,000. Only the slice from Rs 600,001 to 1,200,000 is taxed, and only at 1%.
- Total tax: Rs 6,000 a year. That is Rs 500 a month, leaving take-home pay of Rs 99,500 a month. The effective rate is 0.50%, even though the worker's top slab rate is 1%.
The same method at higher incomes shows the slices stacking up. A worker on Rs 300,000 a month earns Rs 3,600,000 a year, and the tax builds as Rs 6,000 from the second slab, Rs 110,000 from the third, Rs 230,000 from the fourth, and Rs 120,000 from the fifth, for a total of Rs 466,000 a year. That is Rs 38,833.33 a month deducted, take-home pay of Rs 261,166.67 a month, and an effective rate of 12.94%, far below the 30% top slab rate this worker reaches.
At the very top, the surcharge joins in. A worker on Rs 1,000,000 a month earns Rs 12,000,000 a year. Slab tax comes to Rs 3,381,000, and because income passes Rs 10,000,000, the 9% surcharge adds Rs 304,290, for a total of Rs 3,685,290 a year. The monthly deduction is Rs 307,107.50, take-home pay is Rs 692,892.50 a month, and the effective rate is 30.71%, still below the 35% top rate plus surcharge that a quick glance at the table might suggest.
Common mistakes
- Applying the top rate to the whole salary. The classic error. Tax applies slice by slice, so the effective rate is always lower than the top slab rate, sometimes dramatically lower.
- Using last year's slabs. The 2025 budget cut the middle rates, so any guide or calculator quoting 5%, 15%, and 25% for the middle slabs is out of date and will overstate your tax.
- Entering gross salary when your payslip taxes a different figure. Allowances and deductions change taxable income. If your employer's withholding looks lower than the calculator's answer, the taxable figure on your payslip is the first thing to compare.
- Forgetting the surcharge threshold. Below Rs 10,000,000 there is no surcharge for salaried workers. Above it, the surcharge applies to the tax, not the income, which keeps it far smaller than 9% of salary.
- Dividing annual tax by 12 and expecting the payslip to match to the rupee. Employers withhold in monthly instalments, but bonuses, arrears, and mid-year salary changes shift the monthly figure during the year. The yearly total is the reliable comparison.
Practical tips
Check your first payslip of the tax year against the calculator, not your last one, since mid-year changes distort the comparison. If your salary rises mid-year, re-run the calculation at the new annual figure, because a raise that crosses a slab boundary raises the tax on the slice above the boundary only, never on the whole salary. Keep the slab table handy when a raise is offered: the raise's real value is the increase minus the tax on that slice alone. And when tax year 2026-27 slabs arrive with the next budget, check the rates again before trusting any saved calculation, since Pakistan revises these slabs almost every year.
Frequently asked questions
How much tax do I pay on a salary of Rs 100,000 a month in Pakistan?
On Rs 1,200,000 a year, the tax is Rs 6,000 a year, or Rs 500 a month, leaving take-home pay of Rs 99,500 a month. Only the slice above Rs 600,000 is taxed, and only at 1%.
What salary is tax free in Pakistan in 2025-26?
Annual taxable income up to Rs 600,000, which is Rs 50,000 a month, is taxed at 0%. Above that, only the income in each higher slab is taxed at that slab's rate.
What changed in the 2025-26 salary slabs?
The Finance Act 2025 cut the middle rates: the second slab fell from 5% to 1%, the third from 15% to 11%, and the fourth from 25% to 23%. The top rate stayed at 35%, and the 9% surcharge above Rs 10,000,000 still applies to the tax.
Is the surcharge charged on my whole salary?
No. The 9% surcharge applies to the tax payable, and only when taxable income passes Rs 10,000,000. On a slab tax of Rs 3,381,000 it adds Rs 304,290, which is a small fraction of the salary itself.
Why does my employer's deduction differ from this calculator?
Usually because taxable income differs from gross salary: allowances, exemptions, and deductions change the figure the slabs apply to. Bonuses, arrears, and mid-year raises also shift monthly withholding, so compare the yearly totals first.

Salary tax in Pakistan rewards anyone who reads the slabs instead of fearing the top rate, because the slice system means most workers keep far more of each raise than the headline rate suggests. Run your own salary through the slabs, compare the yearly total with your payslip, and revisit the rates when the next budget lands.
