A transfer tax is a tax on the passing of title to property from one person (or entity) to another.

In a narrow legal sense, a transfer tax is essentially a transaction fee imposed on the transfer of title to property from one entity to another. This kind of tax is typically imposed where there is a legal requirement for registration of the transfer, such as transfers of real estate, shares, or bond. Examples of such taxes include some forms of stamp duty, real estate transfer tax, and levies for the formal registration of a transfer. In some jurisdictions, transfers of certain forms of property require confirmation by a notary. While notarial fees may add to the cost of the transaction, they are not a transfer tax in the strict sense of the term.
