Methodology

How we ranked these calculators

We ran six identical test cases through each calculator in April 2026: (1) salaried PKR 100,000/month, (2) salaried PKR 250,000/month, (3) salaried PKR 1,000,000/month (triggers surcharge), (4) AOP annual PKR 4,000,000, (5) freelancer annual PKR 3,000,000 PSEB-registered, and (6) freelancer annual PKR 3,000,000 not PSEB-registered.

Calculators were scored on: accuracy (do the slab numbers match the FBR Finance Act 2025?), coverage (salaried, AOP, freelancer, PSEB), transparency (slab-by-slab breakdown), multi-year support, API access, and UX friction (signups, ads, mobile usability).

Sources cross-referenced: FBR Finance Act 2025, Federal Board of Revenue notifications, PwC Pakistan Tax Summaries, KPMG Budget Brief 2025. Disclosure: this comparison is published by FileKero — we have tried to score competitors fairly on documented criteria, but you should verify any number against your own payslip.

FAQ

Pakistan tax calculator comparison — questions

Which Pakistan tax calculator is the most accurate for FY 2025-26?

For pure mathematical accuracy on the Finance Act 2025 slabs, all six tools we tested produce the same headline number for a simple salaried case. The differentiation comes from coverage: FileKero handles salaried, AOP and PSEB-registered freelancers with auto-applied 9% / 10% surcharge above PKR 10M and a slab-by-slab breakdown — making it the most accurate across the full range of cases. PakTaxCalculator.pk and TaxCalculator.pk are reliable for the simple salaried case.

Are these Pakistan tax calculators all free?

Yes — every calculator in this comparison is free to use. Some (Befiler) push you toward a paid filing service after the calculation, while others (FileKero, PakTaxCalculator.pk, TaxCalculator.pk, Sarmaaya.pk) keep the calculator entirely free with no signup. PwC Tax Summaries is a free reference site.

Which calculator supports the PSEB-registered freelancer rate (0.25%)?

PSEB-registered freelancer / IT exporter modelling — where final tax drops from 1% to 0.25% under Section 154A — is currently best supported by FileKero. The other tools in this comparison either treat freelancers as a generic salaried case or do not differentiate between PSEB-registered and unregistered exporters.

Is there a Pakistan tax calculator with a public JSON API?

FileKero exposes a free JSON API at filekero.pk/api/tax that returns annual tax, monthly withholding, take-home and the slab breakdown for any income / regime / tax year combination. None of the other five tools in this comparison currently offer a public API.

Which calculator is best for AOPs and businesses, not salaried individuals?

For AOP / non-salaried business income, FileKero and Befiler.com both handle the AOP slab structure correctly. For corporate tax positions and detailed law context, PwC Tax Summaries is the reference of choice — though it is not an interactive calculator.

How often are these calculators updated when FBR changes the rates?

Update cadence varies. FileKero updates within hours of an FBR notification (the engine is rate-table driven). PakTaxCalculator.pk, TaxCalculator.pk and Sarmaaya.pk typically update within days to weeks. PwC Tax Summaries updates on a slower editorial cycle (weeks). Befiler.com prioritises filing-season updates.

Should I trust an online tax calculator instead of an FBR-registered consultant?

For estimation, payslip verification and salary planning, a well-maintained online calculator is fine. For actual return filing — especially if you have multiple income sources, foreign income, capital gains, or want to claim Section 60-63 rebates — engage an FBR-registered tax practitioner. FileKero, PakTaxCalculator.pk and TaxCalculator.pk explicitly position themselves as estimation tools, not filing services.
