Pakistan Income Tax Basics: The Terms Behind Every Calculation

Ten ideas explain almost every result on this site. Each is set out in a few sentences with the section of the Income Tax Ordinance 2001 it comes from, a one-line summary, and the calculator or guide that goes further.

Tax year

The normal tax year is the twelve months ending on 30 June (section 74). FBR names it after the calendar year in which it ends, so Tax Year 2026 runs from 1 July 2025 to 30 June 2026. This site writes the same year as 2025-26.

Rates are set year by year, usually by the Finance Act passed each June, so a figure is only meaningful with its tax year. Tax Year 2026-27 runs from 1 July 2026 to 30 June 2027.

In simple words: The tax year is the July-to-June year your income is counted in. Always check which one a figure is for.

Total income and taxable income

Income is grouped under five heads: salary, income from property, income from business, capital gains, and income from other sources (section 11). Your total income is the income under all heads added together (section 10).

Your taxable income is total income less any deductible allowances, but not below zero (section 9). The tax rates are applied to taxable income.

In simple words: Add up what you earned from every source, take off the allowances the law permits, and the rates apply to what is left.

Exemptions, deductions and tax credits

The law reduces tax in three different ways, and they are worth different amounts:

  • An exemption keeps income out of the calculation altogether — for example the medical allowance, up to 10% of basic salary, where the employer does not provide free medical treatment (clause 139, Part I, Second Schedule).
  • A deductible allowance is subtracted from total income before the rates apply — for example Zakat paid (section 60).
  • A tax credit is subtracted from the tax itself — for example the credit for contributions to an approved pension fund (section 63) or for charitable donations (section 61), each worked out under the formula in its section.

In simple words: An exemption is never counted, a deduction lowers the income that is taxed, and a credit lowers the tax.

Slabs, marginal rate and effective rate

Income tax is charged in slabs: each band of taxable income is taxed at its own rate. Your marginal rate is the rate on the next rupee you earn; your effective rate is your total tax divided by your income. Because the lower bands are taxed at lower rates, the effective rate is always below the marginal rate once you are past the first band.

In simple words: A pay rise is taxed at your marginal rate, but your tax as a share of all your income is the lower effective rate.

Salaried or non-salaried rates

There are two rate schedules for individuals. The salaried rates apply only if salary makes up more than 75% of your taxable income; otherwise the non-salaried rates, which are steeper, apply to all of it (First Schedule, Part I, Division I).

In simple words: If salary is more than three-quarters of your taxable income, you use the salaried rates.

Withholding tax and final tax

Many payments have tax taken off before you receive them: your employer deducts it from salary (section 149), a bank from profit on deposits (section 151), a tenant from rent (section 155). What that deduction counts as depends on the provision:

  • An advance is credited against your tax for the year when you file (section 168) — salary withholding works this way, as does the tax a non-filer pays on cash withdrawals (section 231AB).
  • A minimum tax cannot be reduced below the amount deducted — the deduction from bank profit is minimum tax for most individuals (section 151(3)).
  • A final tax settles the tax on that income — for example the deduction from export proceeds under section 154A, where its conditions are met.

In simple words: Tax deducted before you are paid may count towards your bill, set a floor under it, or settle it — the provision decides which.

Tax liability, tax payable and refund

Your tax liability is the tax due on your taxable income for the year. Set the tax already deducted or paid against it: if less was deducted, the difference is payable with your return; if more was deducted, the excess is refundable on a claim (section 170). A refund is not guaranteed — FBR first sets any excess against other tax you owe, and claims are subject to verification.

In simple words: Liability is what you owe for the year; payable or refundable is the gap between that and what was already deducted.

Filer, non-filer and the Active Taxpayers List

A filer in everyday use means a person on FBR’s Active Taxpayers List (section 181A); a non-filer is anyone not on it. Filing status does not change the income tax slab rates, but under the Tenth Schedule many withholding rates are higher for a person not on the list — often double.

In simple words: Not being on the Active Taxpayers List mostly costs you through higher tax deducted on transactions.

Capital gain and holding period

When you sell property, the capital gain is broadly the sale price (or the official value, if higher) less what the property cost you, and it is taxed under section 37(1A). The holding period is the time between the date you became the owner and the date you sold. For property bought before 1 July 2024 the rate falls the longer you held it; for property bought on or after that date, a seller on the Active Taxpayers List pays a flat 15% whatever the holding period.

In simple words: The gain is what you sold for minus what it cost, and for older purchases how long you held it changes the rate.

Which date decides the rules

  • Salary, business and rent are taxed by the tax year the income belongs to.
  • Tax collected on a transaction — buying a car, withdrawing cash — uses the rate in force on the date of the transaction.
  • Property gains depend on two dates: when you became the owner and when you sold.

In simple words: Income follows the tax year; a transaction follows the date it happened.
