How This Calculator Works

1

Project Your Full-Year Income

We add your income earned so far (July 2025 onwards) to your expected remaining income to estimate your total annual income for FY 2025-26.

2

Calculate Full-Year Tax

We apply the official FBR 2025-26 income tax slabs to your projected annual income to find your total tax liability for the year.

3

Subtract What You've Paid

We subtract the tax already deducted by your employer (or self-paid). The difference is what you still owe — or your estimated refund if you've overpaid.

// The core formula

projected_annual_income = income_so_far + expected_remaining

full_year_tax = FBR_slabs(projected_annual_income)

remaining_tax = full_year_tax − tax_already_paid

Frequently Asked Questions

Where do I find how much tax has been deducted from my salary?
Check your monthly payslips — it's listed as "Income Tax" or "Withholding Tax" deduction. Add up all deductions from July 2025 to today. Your employer must also provide an annual tax deduction certificate (Form 16) at year-end.
What if I have multiple income sources?
Combine all income sources when entering "Total Income Earned So Far" and "Expected Remaining Income." Similarly, add up all withholding tax from every source for the "Tax Already Paid" field. If your income comes from different types (salaried + business), consult a tax professional as special rules may apply.
When is the tax filing deadline for FY 2025-26?
The official FBR deadline to file your income tax return for Tax Year 2026 (FY 2025-26) is September 30, 2026. Filing on time maintains your Active Taxpayer List (ATL) status, which entitles you to lower withholding tax rates on banking, property, and other transactions.
What does this calculator not account for?
This calculator uses gross income only. It does not factor in allowable deductions such as Zakat payments, pension fund contributions, charitable donations (up to 30% of taxable income for approved organizations), medical allowance exemptions, or education tax credits. Your actual tax liability after deductions may be lower than shown here.
My employer adjusts my deductions automatically — do I still need this?
If your employer recalculates your withholding whenever your salary changes, you may be fully covered. However, this calculator is still useful to independently verify your employer's calculation, especially after a raise, bonus, or mid-year job change. It also helps if you have income from sources your employer isn't aware of.
