Stamp Duties

Stamp duty is a charge on certain documents and transactions. Stamp duty is charged at either a flat rate or an ad valorem rate (based on the value of the transaction) depending on the particular document or transaction.

Calculators are available to assist you in estimating the amount of stamp duty payable. There is also a Stamp Duty Glossary of Terms which may help you to understand some of the terms used.
