When PP.36 applies
When paying a foreign provider for a service performed abroad but used in Thailand — such as consulting or software licences — the Thai payer must self-assess and remit VAT.
Deadline
By the 7th of the month after payment (online filing may be extended by notice). VAT-registered payers can claim the tax paid as input VAT the following month.
Separate from withholding tax
Payments abroad may also require withholding tax on PND.54, depending on the income type and any Double Taxation Agreement.
Frequently asked questions
Must a non-VAT-registered payer file?
Yes, the VAT must be remitted, but it cannot be credited.
Do foreign digital services use PP.36?
Foreign digital providers registered for Thai VAT may already charge it; check the receipt to avoid paying twice.
