How we source, verify, and update tax content on TaxCalc.asia. Last updated: June 15, 2026.

Our Approach

TaxCalc.asia provides free tax calculators and educational content for freelancers in 6 Asian countries. Every number on this site — every tax bracket, deduction threshold, and regime rule — is sourced from official government publications. We do not fabricate data, approximate rates, or rely on third-party interpretations.

Accuracy & Corrections

We strive for accuracy but tax laws are complex and subject to interpretation. If you find an error — a wrong bracket, an outdated threshold, a missing deduction — please contact us with the specific details and we will:

  1. Investigate and verify the discrepancy against official sources
  2. Correct the error within 5 business days if confirmed
  3. Note the correction date and nature of the change
