Stamp Tax (stamp duty)

Today, we will explain the stamp tax (stamp duty) that will be affixed to the contract when you make a purchase or sale of real estate. At the time of a real estate sales contract, both the buyer and the seller will sign and seal the contract, and store each part. At that time, it is obligatory to affix a stamp to the contract kept by each. You can pay the tax by purchasing the stamp tax, attaching it to the contract, and postmarking it.

The documents that require stamp duty are the 1st document to the 20th document, and the real estate sales contract corresponds to the 1st document of the stamp tax list. There are four types of documents that correspond to the first document.

1 Real estate, mining right, intangible property right, ship or aircraft, or contract for transfer of business
2 Contract for setting or transferring land rights or land lease rights
3 Consumption loan agreement
4 Transportation contract

Stamp tax is also explained as follows.​
 Stamp tax is levied on certain documents such as contracts, bills and share certificates. As a rule, the tax is levied by affixing revenue stamps covering the amount equal to the stamp tax to those documents. However, in certain cases, such as when many taxable documents are processed repeatedly, taxpayers may, for convenience, choose self-assessment or payment in cash. Tax rates vary from 200 yen to 600,000 yen per document. Revenue stamps are also used for payment of registration license tax levied when registering the establishment or transfer of property rights and for payment of national examination fees.
