Which tax calculator do you need?
Pakistan taxes different kinds of income under different heads, at different rates, collected by different authorities. Picking the wrong one produces a confidently wrong number, so the short version is:
- You draw a salary and it is most of your income. Use the salary tax calculator. The salaried slabs apply where salary is more than 75% of your total taxable income.
- You run a business, freelance or consult. Use the business tax calculator. The non-salaried slabs are considerably steeper — up to 45% against 35% — but you deduct your expenses first.
- You are charging or paying tax on a sale. Use the sales tax calculator. Goods are federal at 18%; services are provincial at 15% or 16% depending on where the work is rendered.
- You let out property. Use the rental income tax calculator. Note that what your tenant withholds under section 155 and what you finally owe under section 15 are different amounts.
- You are not sure which schedule you fall under. Read the salaried vs non-salaried comparison first — getting this wrong is the most consequential error in Pakistani tax calculation.
Guides, not just calculators
Working out what you owe is one thing; knowing what to do about it is another. The tax guides cover the rules around the numbers — most urgently how to file your return on FBR IRIS, which is due by 30 September 2026 and carries a penalty plus an ATL restoration surcharge if you miss it.

How these calculators are kept accurate
Every rate lives in one place in the codebase and is asserted by an automated test suite that checks each slab table is internally consistent — that the fixed amount carried into each slab genuinely equals the tax accumulated by all the slabs below it. That catches the most common failure in published rate tables, where a rate is edited but the carried figures are not.
Each calculator also shows its slab-by-slab working, so you can reconcile the result against your own payslip, invoice or rent agreement rather than taking it on trust. These are independent tools and not an FBR service — verify your position against the relevant Finance Act or with a practitioner before filing.
