NISAAB applies Pakistan's official salary and business/AOP tax slabs to your income in real time — monthly, yearly, and bracket by bracket — covering every fiscal year back to 2021–22.
Most calculators just spit out one number. We show you the ladder you're standing on, the slice taxed at each step, and a slip you can actually keep — for salary or business income.
Switch between salaried and business/AOP tax tables in the same calculator — each with its own official FBR slab structure.
Toggle from FY 2026–27 all the way back to FY 2021–22, or pick a custom year range to see totals across multiple budgets.
Generate a clean, shareable calculation slip for your records, your HR team, or your accountant — in one click.
Every calculation runs client-side in JavaScript. Your income figures are never sent to a server.
Interactive Google Charts show the tax-vs-take-home split and a year-over-year comparison at a glance.
Our blog and 15-question FAQ explain filer status, deductions, and slab changes in language built for real people.
Unlike a real FBR filing, this takes under a minute — because that's all a tax estimate should ever take.
Start calculatingPick the tab that matches your income type — each uses its own official FBR slab table.
Default is the current FY 2026–27. Switch to any year back to 2021–22, or compare a whole range at once.
Get your monthly and annual tax, take-home pay, marginal bracket, and a full slab breakdown — plus a PDF to keep.
Once you know what you owe, our team can prepare and file your return with FBR — for salaried employees, freelancers, business owners, and non-filers catching up on past years.
