NISAAB started from a simple frustration: most Pakistani tax calculators give you one number and nothing else. We built the tool we wanted — one that shows its work — and then built a team behind it for people who need more than an estimate.
NISAAB is a free, browser-based salary and business tax calculator for Pakistan, covering every FBR fiscal year from 2021-22 through the current 2026-27. Every calculation happens on your device — we never see or store your income figures. Alongside the calculator, we publish plain-language guides on filer status, deductions, and slab changes, and offer paid consulting for people who want a professional to actually prepare and file their return.
Tax slabs change almost every year in Pakistan, and the difference between salary and business/AOP rates trips up a lot of people who assume one calculator covers both. We wanted a tool that shows the bracket you're in, the slice of income taxed at each rate, and how this year compares to previous ones — not just a final number with no context. That's why the calculator includes a visual rate ladder, a year-over-year comparison, and a downloadable PDF slip for your records.
Salaried employees checking their payslip deductions. Freelancers and sole proprietors trying to understand business/AOP rates. HR and payroll teams double-checking withholding. Non-filers working out what they'd owe across several past years before catching up. And anyone who's simply tired of tax calculators that don't explain themselves.
Every slab table in our calculator is cross-checked against official Finance Act text and FBR notifications for the relevant tax year. We're upfront that this is an estimation tool, not a substitute for a registered tax practitioner or an official FBR assessment — but we hold ourselves to getting the arithmetic exactly right, every year we support.
