Thailand VAT 36 filing 2026: imported services | GENTLE LAW
Updated: 16 hours ago
Thailand VAT 36 filing 2026 is one of the most overlooked tax obligations for foreign SMEs in Thailand. The risk is simple: a company pays an overseas service provider, treats the invoice as just another vendor bill, and misses the Thai VAT remittance obligation that can arise when the service is used in Thailand. The Revenue Department’s English VAT guidance states that services utilized in Thailand and supplied by providers in other countries are subject to VAT in Thailand, and in that case the service recipient in Thailand is obliged to file VAT return Form VAT 36 and pay tax, if any, on behalf of the service provider.
This guide explains Thailand VAT 36 filing 2026 in plain English: what VAT 36 is, when it applies, the filing deadline, how internet filing works, and how foreign SMEs can build a reliable monthly control so the issue is caught before payment.

Thailand VAT 36 filing 2026 in plain English
Thailand VAT 36 filing 2026 is the process of remitting VAT under Form PP.36 in situations where the payer in Thailand must remit VAT on behalf of another party under the Revenue Code framework. The Revenue Department’s official PP.36 form shows three main scenarios on the face of the form: payment to a foreign supplier temporarily carrying on business in Thailand or to a supplier providing services overseas, receipt of transferred goods or rights in services subject to 0 percent tax, and certain auction-related cases. For most foreign SMEs, the most relevant scenario is payment for overseas services used in Thailand.
The legal anchor is Section 83/6 of the Revenue Code. When payment for goods or services is made to a business person providing services abroad and such service is used in Thailand, the payer is required to remit the VAT amount that the business person is liable for.
When Thailand VAT 36 filing 2026 usually matters for foreign SMEs
In practice, Thailand VAT 36 filing 2026 is most likely to arise when a Thai entity pays for cross-border services such as software subscriptions, cloud services, consulting, licensing support, digital back-office functions, or management services, and the benefit of the service is used in Thailand. The Revenue Department’s English VAT guidance expressly says that a service is deemed provided in Thailand if it is performed elsewhere and utilized in Thailand.
That point matters because many foreign SMEs focus only on where the supplier is located. Thai VAT looks at where the service is utilized. So a foreign invoice does not automatically mean “outside Thai VAT.”
Official filing deadline for Thailand VAT 36 filing 2026
A Revenue Department explanation on internet filing deadline extensions states that PP.36, in the case of payment for goods or services to certain non-resident suppliers, is normally due within 7 days from the end of the month of payment, and that internet filing extends this deadline to within 15 days from the end of that month for the covered cases. The extension applies only where the filing is made through the internet system.
For operational purposes, foreign SMEs should treat Thailand VAT 36 filing 2026 as a month-end triggered obligation:
paper baseline: within 7 days from the end of the month of payment
internet filing: within 15 days from the end of the month of payment, where the extension applies and the filing is made online.
Key takeaways
Thailand VAT 36 filing 2026 is mainly relevant when a Thai payer buys services from overseas and those services are used in Thailand.
The official PP.36 form confirms that one of its main use cases is payment to a supplier providing services overseas, where the services are used in Thailand.
PP.36 is ordinarily due within 7 days from the end of the month of payment, but internet filing extends that to within 15 days from the end of the month in covered cases.
As of April 2026, Revenue Department pages still actively list PP.36 in filing schedules and in the current VAT e-Filing menu.
Common misconceptions
A common misconception is that VAT 36 only matters when the foreign supplier physically comes to Thailand. That is not correct. Section 83/6 covers services provided abroad utilized in Thailand.
Another misconception is that PP.36 follows the same monthly timing as PP.30. It does not.
A third misconception is that you can fix it later in the annual accounts. PP.36 is a monthly remittance obligation tied to the payment month.
