Stamp Duty
Calculate stamp duty by contract and document type.
TL
The tool uses common 2026 proportional stamp duty rates and official declaration stamp duty amounts. The legal per-paper upper limit is applied.
How is stamp duty calculated?
For proportional stamp duty, the document amount is multiplied by the relevant per-thousand rate and then compared with the maximum amount applicable to each paper. For fixed stamp duty, the officially determined fixed amount is multiplied by the number of documents.
Scope and assumptions
The tool uses commonly applied proportional rates and fixed declaration stamp duty amounts for 2026. Exemptions, formally drafted special contracts, multiple copies, withholding, refund procedures and industry-specific paper types are not included.
