Revised asset valuation method for the calculation of inheritance tax for shares outside the stock market

The Cabinet approved in principle a revision to the asset valuation method for the inheritance tax calculation:

Current Proposed Revision
The calculation of the value of securities not registered in the Stock Exchange of Thailand shall be carried out as follows:

(1) Shares of a company or juristic partnership shall be considered as the book value in the accounting period prior to the accounting period in which the ownership of the shares is acquired, except in cases where the inheritance in the form of shares is a share of a company or juristic partnership which holds shares in another company or juristic partnership, in which case the share value shall be considered as follows:

The calculation of the value of securities not registered in the Stock Exchange of Thailand shall be carried out as follows:

(1) Shares of a company or juristic partnership shall be considered as the book value in the accounting period prior to the accounting period in which the ownership of the shares is acquired, except in cases where the inheritance in the form of shares is a share of a company or juristic partnership which holds shares in another company or juristic  partnership, in which case the share value shall be considered as follows:

As a result, the calculation of share value for companies or juristic partnerships that are not listed on the Stock Exchange of Thailand will be based on the book value from the accounting period prior to the period in which ownership of the shares is acquired, regardless of whether they hold shares in other companies or juristic partnerships.

*Please note that the inheritance tax applies only in cases where a person inherits assets with a total net value exceeding THB 100 million (approx. EUR 2.5 million) and does not apply to the assets inherited from a legally married spouse. Parents and descendants, including children, of the deceased person are subject to a tax rate of 5% of the exceeding amount. For other cases, the tax rate is 10% of the exceeding amount.
