Reference

How this calculator applies the schedule

Amount-based duty

For leases, service agreements, loans, share transfers, hire-purchase, and certain guarantees, duty is calculated by rounding up to the next schedule band.

Fixed duty

Some instruments use fixed amounts, such as authorization letters, proxy letters, company documents, partnership contracts, and duplicates.

Cancellation of stamp

The schedule separately identifies who is liable to pay duty and who is liable to cancel the stamp. The result shows both parties.

This calculator is for general estimation only and is not legal or tax advice. Instrument classification, exemptions, electronic stamp duty, and timing rules should be confirmed before signing or filing. Source: Thai Revenue Department Stamp Duty Schedule.
