How FreelanceTaxPK Calculates Tax & Keeps Data Updated

Last updated: December 26, 2025 | Author: FreelanceTaxPK Editorial Team

Transparency is important to us. This guide explains exactly how FreelanceTaxPK calculates taxes, where we source our data, how we keep information updated, and the limitations of our calculator.

Our Data Sources

FreelanceTaxPK uses official tax information from authoritative sources:

  • FBR (Federal Board of Revenue): Official tax slabs and rates published by FBR
  • Federal Budget Documents: Annual budget announcements that include tax policy changes
  • FBR Circulars and Notifications: Official updates and clarifications issued by FBR
  • Official Government Publications: Verified tax information from government sources

We do not use third-party interpretations or unofficial sources. All tax rates and slabs are based on official FBR documentation.

Tax Calculation Methodology

For Salaried Individuals

Our calculator uses the progressive tax system:

  1. Determines taxable income (gross income minus deductions, if applicable)
  2. Identifies the applicable tax slab based on income level
  3. Calculates fixed tax from previous slabs (if applicable)
  4. Calculates tax on excess income in the current slab
  5. Adds both components to get total tax

Example: For PKR 1,500,000 income:

  • First PKR 600,000: 0% = PKR 0
  • Next PKR 600,000: 1% = PKR 6,000
  • Remaining PKR 300,000: 11% = PKR 33,000
  • Total Tax: PKR 39,000

For Freelancers (Export Services)

Export services use final tax regime:

  • PSEB Registered: 0.25% of gross income (final tax)
  • Not Registered: 1% of gross income (final tax)

Important: This is a final tax, meaning no deductions apply. Tax is calculated on gross income, not net income.

For Freelancers (Local Services)

Local services use progressive tax slabs (same as salaried individuals), but you can claim business deductions when filing your actual return. Our calculator shows tax on taxable income - you need to calculate deductions separately.

For Self-Employed and Business Owners

Uses progressive tax slabs. The calculator shows tax on taxable income (after deductions). You need to calculate your deductions separately when filing, as deductions vary significantly by individual circumstances.

Update Frequency

We update our calculator regularly to ensure accuracy:

  • Annually: After Federal Budget announcements (typically in June)
  • As Needed: When FBR issues new circulars or notifications
  • Regularly: We monitor FBR announcements throughout the year
  • Immediately: For critical tax law changes that affect calculations

Current Tax Year

Our calculator currently uses tax slabs for Tax Year 2025-2026, effective from July 1, 2025. The tax year runs from July 1, 2025 to June 30, 2026.

We clearly display the tax year on our calculator and update it when new tax years become effective.
