How to Calculate Income Tax in Pakistan (FY 2025-26)
By H.A. Sabir — PakTax.pk
If you have ever looked at your payslip and wondered why a certain amount was deducted as income tax, you are not alone. Income tax calculation in Pakistan confuses millions of salaried employees, business owners, and freelancers every single year. The Federal Board of Revenue (FBR) updates tax slabs annually, rates change with every Federal Budget, and most people rely entirely on their employer or accountant without understanding what they are actually paying.
This guide changes that. We will walk you through exactly how Pakistan income tax works for FY 2025-26, step by step, with real examples, slab tables, and a free calculator you can use right now.
What Is Income Tax in Pakistan?
Income tax in Pakistan is a direct tax levied by the Federal Board of Revenue on income earned by individuals, salaried employees, businesses, and associations during a fiscal year. The fiscal year in Pakistan runs from 1st July to 30th June each year.
For salaried employees, income tax is deducted at source by the employer every month — this is called Tax Deduction at Source or TDS. Your employer calculates your expected annual tax liability and divides it by 12 to arrive at your monthly deduction amount.
For self-employed individuals, freelancers, and business owners, income tax is paid either through advance tax payments during the year or through an annual tax return filed on the FBR IRIS portal.
Who Has to Pay Income Tax in Pakistan?
Under Pakistani tax law, every individual whose annual income exceeds PKR 600,000 is liable to pay income tax. This threshold applies to the following categories of taxpayers:
- Salaried employees in public and private sectors
- Self-employed individuals and sole proprietors
- Business owners under AOP (Association of Persons) structures
- Freelancers earning above the threshold
- Rental income earners
- Commission-based earners
- Directors and executives receiving salaries or bonuses
If your total annual income is PKR 600,000 or below — meaning PKR 50,000 per month or less — you fall in the zero percent tax bracket and owe no income tax for FY 2025-26.
Understanding Pakistan's Progressive Tax System
Pakistan uses a progressive tax system, which means higher income is taxed at a higher rate. However, the higher rate only applies to the portion of income that falls within that specific slab — not your entire income. This is the most commonly misunderstood aspect of income tax in Pakistan.
Think of it as filling up a series of buckets. Each bucket has a fixed capacity (the slab range) and its own tax rate. Your income fills the buckets from the lowest to the highest. Each bucket is taxed only at its own rate, regardless of how high your total income goes.
This means moving into a higher tax slab does not suddenly make your entire income more expensive. Only the extra income above the slab boundary gets taxed at the higher rate.
FBR Salaried Tax Slabs FY 2025-26 — Official Rates
The following tax slabs are the official FBR rates for salaried individuals and sole proprietors for the fiscal year 2025-26. These rates were published in the Finance Act following the Federal Budget announcement.
| Annual Income (PKR) | Monthly Salary | Tax Rate | Fixed Tax |
|---|---|---|---|
| Up to 600,000 | Up to 50,000 | 0% | PKR 0 |
| 600,001 – 1,200,000 | 50,001 – 100,000 | 1% | PKR 0 |
| 1,200,001 – 2,200,000 | 100,001 – 183,333 | 11% | PKR 6,000 |
| 2,200,001 – 3,200,000 | 183,334 – 266,667 | 23% | PKR 116,000 |
| 3,200,001 – 4,100,000 | 266,668 – 341,667 | 30% | PKR 346,000 |
| Above 4,100,000 | Above 341,667 | 35% | PKR 616,000 |
Step-by-Step Income Tax Calculation Example
Let us work through a real example. Say your monthly salary is PKR 150,000. Here is exactly how to calculate your annual income tax for FY 2025-26.
Step 1 — Annual Income
PKR 150,000 x 12 = PKR 1,800,000 per year
Step 2 — Identify the Slab
PKR 1,800,000 falls in Slab 3 — between PKR 1,200,001 and PKR 2,200,000 — taxed at 11%
Step 3 — Calculate Annual Tax
Fixed tax from lower slabs: PKR 6,000
Income above PKR 1,200,000: PKR 1,800,000 - PKR 1,200,000 = PKR 600,000
Marginal tax: 11% x PKR 600,000 = PKR 66,000
Total Annual Tax = PKR 6,000 + PKR 66,000 = PKR 72,000
Step 4 — Monthly Breakdown
Notice that the effective tax rate is only 4%, even though the marginal rate for this slab is 11%. This is because the lower slabs are taxed at lower rates — the 11% only applies to the portion above PKR 1,200,000.
Second Example — Higher Income
Let us try another example with a monthly salary of PKR 300,000.
Annual Income
PKR 300,000 x 12 = PKR 3,600,000
Slab
PKR 3,600,000 falls in Slab 5 — between PKR 3,200,001 and PKR 4,100,000 — taxed at 30%
Tax Calculation
Fixed tax: PKR 346,000
Marginal income: PKR 3,600,000 - PKR 3,200,000 = PKR 400,000
Marginal tax: 30% x PKR 400,000 = PKR 120,000
Total Annual Tax = PKR 346,000 + PKR 120,000 = PKR 466,000
What Is the Effective Tax Rate vs Marginal Tax Rate?
These two terms confuse a lot of people. Understanding the difference is important for accurate financial planning.
The marginal tax rate is the rate applied to the last rupee of income — the rate of the slab your income falls in. For a PKR 1,800,000 income, the marginal rate is 11%.
The effective tax rate is the average rate across all your income — your total tax divided by your total income. For a PKR 1,800,000 income with PKR 72,000 tax, the effective rate is 4%.
The effective tax rate is always lower than the marginal rate because your lower income slabs are taxed at lower rates. When planning your finances, always use the effective rate to understand your real tax burden.
Common Mistakes People Make When Calculating Income Tax
Applying the slab rate to all income
The most common mistake. If you earn PKR 1,500,000, only the portion above PKR 1,200,000 is taxed at 11%. The first PKR 600,000 is still zero, and the next PKR 600,000 is taxed at 1%.
Confusing salaried and AOP rates
Salaried individuals and sole proprietors use the same slabs with rates from 0 to 35 percent. But if you run a business as an AOP or partnership, different and significantly higher rates apply ranging from 0 to 45 percent.
Using last year's slabs
FBR revises tax slabs every fiscal year. The FY 2025-26 slabs are notably different from FY 2024-25. Always confirm you are using the correct year. PakTax.pk supports all three recent years.
Ignoring the fixed tax component
Each slab has a fixed tax amount representing the accumulated tax from lower slabs. You must add this fixed component to your marginal calculation to get the correct total.
Not accounting for bonuses
Bonuses and incentives are added to your salary for tax purposes. A large annual bonus can push your income into a higher slab and significantly increase your tax liability.
How to File Your Income Tax Return in Pakistan
Even if your employer deducts tax at source, you are still required to file an annual income tax return with FBR. Filing your return makes you an active taxpayer on the ATL (Active Taxpayers List), which gives you access to lower withholding tax rates on banking transactions, property purchases, and vehicle registration.
The deadline for filing salaried individual returns is typically 30th September each year for the previous fiscal year. Returns are filed online through FBR IRIS portal at iris.fbr.gov.pk.
If your employer has correctly deducted tax throughout the year, filing your return is straightforward. You simply declare your income and tax deducted, and if the amounts match, no additional payment is required.

Frequently Asked Questions
What is the tax-free income limit in Pakistan for FY 2025-26?
The annual tax-free limit for salaried individuals is PKR 600,000, which equals PKR 50,000 per month. Any income above this threshold is subject to progressive tax rates as per FBR slabs for FY 2025-26.
Does Pakistan have a flat tax rate or progressive tax?
Pakistan uses a progressive tax system where higher slabs of income are taxed at higher rates. Only the income falling within each specific slab is taxed at that slab rate — not your entire income.
How is monthly income tax calculated for salaried employees?
Monthly tax is calculated by first computing the annual tax liability using FBR progressive slabs, then dividing that annual figure by 12. Employers deduct this monthly amount directly from your salary under the TDS system.
Is income tax the same for salaried individuals and business owners?
No. Salaried individuals and sole proprietors share the same slab rates of 0 to 35 percent. AOP businesses and partnerships face a separate and higher slab table ranging from 0 to 45 percent.
Can I get a tax refund in Pakistan?
Yes. If your employer deducted more tax than your actual liability — for example due to a mid-year salary reduction or excess deduction — you can claim a refund through FBR IRIS portal when filing your annual tax return.
What is the difference between effective tax rate and marginal tax rate?
The marginal tax rate is the rate applied to your highest income slab. The effective tax rate is your total tax divided by your total income — it is always lower than the marginal rate and gives you a truer picture of your tax burden.
Do I need to file a tax return if my employer already deducts tax?
Yes. Even if your employer deducts tax at source, you are still required to file an annual income tax return with FBR. Filing keeps you on the Active Taxpayers List and entitles you to lower withholding tax rates on various financial transactions.
