Pakistan Income Tax Calculator

Archived historical, non-current snapshot — dated July 9, 2026 (2026-07-09). The salary slabs, surcharge, tax-credit, filer-status, and income assumptions described below may not reflect current Pakistan tax rules. Check authoritative sources for the applicable period before relying on this estimate.

The Pakistan income tax calculator estimates salary tax from a monthly income figure. Enter gross taxable monthly pay in Pakistani rupees, and the calculator converts it to annual income, applies the slab formula embedded in the calculation method, and reports monthly tax, yearly tax, monthly income after tax, and effective tax rate. It is useful for comparing job offers, checking payroll withholding, planning take-home pay, or testing the effect of a raise.

The form labels the currency as Rs. and formats outputs in Pakistani rupees. It is not a live FBR tax engine. Pakistan’s income tax rules can change by tax year, Finance Act, circular, or official interpretation. Use this page to understand the arithmetic of the current calculator, then verify the latest slab, exemption, rebate, and filing rules with the Federal Board of Revenue before making decisions. For household planning, combine this page with the budget calculator, salary calculator, and savings goal calculator.

How to use

Enter your monthly salary before income tax withholding. The input should be taxable monthly salary, not take-home pay. The calculator multiplies it by 12 to get yearly income, applies the relevant annual slab, divides annual tax by 12, and subtracts that monthly tax from monthly salary. The result panel shows four supporting values: monthly income after tax, yearly income, yearly tax, and effective tax rate.

The result assumes the salary is earned evenly across 12 months. If you are comparing a one-time bonus, contract rate, allowance, or arrears payment, convert only the taxable recurring portion into a monthly equivalent before using the calculator. If payroll uses a different averaging method or deducts tax already paid in earlier months, the monthly withholding can differ even when the annual tax is similar.

How it works

Pakistan salary tax is progressive in this calculator. That means only the income inside each higher band is charged at that band’s marginal rate; lower income keeps its lower treatment. The calculation method has six annual bands. Annual income up to Rs. 600,000 has zero tax. Income above that moves through 5%, 15%, 25%, 30%, and 35% marginal bands, with fixed amounts added in higher brackets to account for tax already due on lower bands.

This calculator first annualizes your salary:

$\text{yearly income} = 12 \times \text{monthly income}$

It then applies the relevant annual slab and divides the result by 12:

$\text{monthly tax} = \frac{\text{yearly tax}}{12}$

Monthly after-tax income is:

$\text{after-tax monthly income} = \text{monthly income} - \text{monthly tax}$

Effective tax rate is:

$\text{effective rate} = \frac{\text{yearly tax}}{\text{yearly income}} \times 100$

2025 slab summary

This table describes the calculator’s code, not a promise that the slab remains current. If FBR changes the official bands, the calculator should be updated before it is used for filing or payroll decisions.

Worked example

Use the default input of Rs. 250,000 monthly salary. The calculator first annualizes the salary:

$\text{yearly income} = 12 \times \text{Rs 250,000} = \text{Rs 3,000,000}$

Rs. 3,000,000 falls in the bracket above Rs. 2,200,000 and up to Rs. 3,200,000. The calculator uses the formula Rs. 180,000 plus 25% of the amount above Rs. 2,200,000:

$\text{yearly tax} = \text{Rs 180,000} + 25\% \times (\text{Rs 3,000,000} - \text{Rs 2,200,000})$

The amount above Rs. 2,200,000 is Rs. 800,000. Twenty-five percent of that is Rs. 200,000. Adding the fixed Rs. 180,000 gives yearly tax of Rs. 380,000.

The monthly tax is:

$\text{monthly tax} = \frac{\text{Rs 380,000}}{12} = \text{Rs 31,666.67}$

The monthly income after tax is about Rs. 218,333.33. The effective tax rate is yearly tax divided by yearly income, or about 12.67%. These figures match the current calculation method: the primary result is estimated monthly tax, and the supporting rows show after-tax monthly income, yearly income, yearly tax, and effective rate.

Tax planning context

The calculator intentionally keeps the model narrow. It does not ask for employer withholding already deducted, zakat, pension, medical allowance treatment, tax credits, rebates, business income, property income, capital gains, or non-resident status. It also does not calculate penalties, default surcharge, advance tax, or wealth statement requirements. Those items can materially change an actual return.

For payroll planning, the monthly result is still useful. If an employer offers Rs. 250,000 instead of Rs. 220,000 per month, the raise is not fully available for spending because some of the added income falls in the marginal slab. Compare after-tax income, not only gross pay. For savings planning, use the after-tax amount as the input to the future value calculator or compound interest calculator.

Tax years and slabs change. The form’s result note says it is based on Pakistan 2025 salaried income slabs. If you are filing for a later year, a budget change may have altered thresholds, rates, fixed amounts, or special surcharges. Check FBR before relying on any fixed slab table.

Common mistakes

• Entering annual salary in the monthly salary field.
• Using take-home pay instead of gross taxable salary.
• Applying the highest marginal rate to the entire income instead of only the top slice.
• Forgetting that bonuses, allowances, or non-salary income can change actual tax.
• Treating the calculator as a filing tool rather than an estimate.
• Using the 2025 slab table after FBR has updated the law.
