# Thai companies paying foreign service providers: withholding tax (PND 54) and VAT (PP 36)

Thai companies paying foreign providers often withhold tax on PND 54 and self-assess 7 percent VAT on PP 36. How both work, and treaty relief.

## Key takeaways

- Thai companies paying foreign entities for certain income from Thailand, such as services fees and royalties, withhold tax and file form PND 54.
- The general withholding rate on service fees to foreign companies is 15 percent, often reduced or removed under tax treaties.
- Thai companies that buy services from abroad self-assess 7 percent VAT on form PP 36 and can usually reclaim it as input VAT.
- PND 54 and PP 36 are due within seven days after the end of the month of payment.

A Bangkok e-commerce company pays a Singapore consultancy THB 640,000 for a supply chain review. Its accountant prepares two filings before the 7th of next month: PND 54, for income tax withheld on the fee or, under the Thailand-Singapore treaty, for none; and PP 36, for the 7 percent VAT the company self-assesses on an imported service.

## Withholding tax on PND 54

When a Thai company pays a foreign company that does not carry on business in Thailand for income from Thailand, it generally withholds tax and files PND 54. Common cases:

- service fees,
- royalties for software, trademarks and know-how,
- interest and dividends.

The general rate on service fees to foreign companies is 15 percent. Royalties and interest have their own rates.

## Treaties

Thailand has many tax treaties. Service fees are often treated as business profits, taxable only in the provider's country if it has no permanent establishment in Thailand. Royalties are commonly reduced rather than removed. Obtain the provider's certificate of tax residence and keep it on file.

## VAT on PP 36

A Thai company buying services from abroad that are used in Thailand self-assesses 7 percent VAT and pays it on PP 36. If the company is VAT registered, it can usually claim the amount as input VAT in the following month's return.

## Deadlines

Both PND 54 and PP 36 are due within seven days after the end of the month of payment, with a short extension for e-filing.

## Agree gross or net

Foreign providers often quote net. If you gross up, the company bears the withholding on top of the fee. Settle it in the contract.

## Where Rivet fits

Rivet does not file Thai taxes. A Rivet business account accepts registered companies after verification, including Thai companies, subject to local rules, and pays providers in 120+ countries with each payment matched to its invoice. Rivet is not a bank; regulated partner institutions hold the funds.
