The objective of this guide is to highlight the key concepts of specific business tax in Thailand.
The specific business tax was introduced in 1992 and is imposed on specific types of business in Thailand.
Let’s find out more on specific business tax.
What is specific business tax?
Specific business tax is a type of indirect tax introduced to replace business tax and is imposed on companies excluded from value-added tax (VAT).
Businesses operating in Thailand and exceed a turnover of THB 1.8 million are subject to VAT, an indirect tax imposed on the value-added at each stage of production and distribution. However, the nature of some businesses, such as financial institutions and services, do not allow for a clear distinction between production costs and the value-added.
Who is liable to specific business tax?
Businesses that are subject to specific business tax are:
- Banking under the law governing commercial banking or any other specific law
- The business of finance, securities and credit foncier under the law governing the operation of the business of finance, securities and credit foncier
- Life insurance under the law governing life insurance
- Pawnbroking under the law governing pawnshops
- Business with regular transactions similar to commercial banks, such as the provision of loans, provision of guarantees, exchange of currencies, issuance, purchase or sale of bills or transfer of money abroad by different means
- Sale of immovable property in a commercial or profitable manner, irrespective of the manner in which such property is acquired, only in accordance with the rules, procedures and conditions prescribed by a royal decree
- Sale of securities in a securities market under the law governing securities exchange of Thailand

- Get a clear picture of all the accounting, tax and HR deadlines

Special business tax registration
An entity or individual who is subject to the special business tax must register such tax and submit Form P.T.01 at the Area Revenue Office if in Bangkok or at the District Revenue Office is situated elsewhere within 30 days of the commencement of their operations.
Specific business tax submission deadline
Specific business tax registered businesses must file and pay the tax returns along with submitting Form P.T.40 to the tax office.
The return and payment are due by the 15th of each month and in case of a multiple-branched office, it must be done separately by individual branches/places of business.
In the case that the tax does not reach THB 100, the business does not need to pay tax for that month but still has the duty to file and submit returns.
Where to submit specific business tax returns?
Businesses must submit Form P.T.40 and pay taxes at the following locations:
- Bangkok
- Branch Area Revenue Office in which the business is located
- Other locations designated by the Director-General of the Revenue Department as the place for filing and paying tax
- Other provinces
- Submit the return at the Branch Area Revenue Office in the location the business is established
- Other locations that the Director-General of the Revenue Department authorises as the place for filing and paying tax
*Note: Filing tax returns and payments can be made through the Revenue Department’s website.
