PND.3 vs PND.53: Thailand Withholding Tax Explained

Picture this: a small import-trading company in Koh Samui hires a freelance Thai graphic designer to redesign its product catalogue. The following month, it also pays a Thai-registered company for website maintenance. The owner, a foreign national running the business with a small team, sends both payments and thinks nothing more of it. Then, during a routine Revenue Department review, it turns out that withholding tax was never deducted from either payment, and no forms were filed. The penalties and surcharges stack up fast. This situation is more common than most business owners realise, and it almost always comes down to not understanding the difference between PND.3 and PND.53.

What Withholding Tax Actually Is

Withholding tax in Thailand is a system where the payer of certain types of income deducts a percentage at source before sending the remaining amount to the recipient. The recipient then uses the withheld amount as a credit against their own tax liability at year end. It is not an additional cost on top of the payment. It is a portion of the payment redirected to the Revenue Department on the recipient's behalf. The obligation to deduct, report, and remit sits with the payer, not the recipient. That is a detail many business owners miss, and it is why the company in our example above was the one facing penalties rather than the designer or the web company.

PND.3: Payments to Individuals

PND.3 is the withholding tax form used when the recipient of a payment is an individual. This covers freelancers, sole traders, individual contractors, and any natural person receiving income that falls under a withholdable category. Common payment types that trigger PND.3 include professional service fees, commissions, rental income paid to an individual landlord, transport fees, and advertising fees, among others. In the example above, the graphic designer is an individual, so the company should have filed PND.3 for that payment. The form must be submitted to the Revenue Department by the seventh day of the month following the payment, or the fifteenth day if filing electronically through the Revenue Department's online portal.

PND.53: Payments to Juristic Persons

PND.53 applies when the recipient is a juristic person, meaning a registered company, limited partnership, or other legal entity. If your business pays a Thai-registered company for services, the withholding tax is reported on PND.53, not PND.3. The filing deadlines are the same as PND.3, the seventh or fifteenth of the following month depending on whether you file on paper or online. In the example above, the web maintenance company is a juristic person, so PND.53 was the correct form. Filing the wrong form, or none at all, creates a compliance gap even if the underlying tax rate happens to be identical.

Which Rates Apply to Which Payments

The withholding tax rate depends on the type of payment, not just on whether the recipient is an individual or a company. That said, rates can differ between PND.3 and PND.53 for the same category of service. Service fees paid to an individual are generally withheld at three percent. Service fees paid to a company are also generally three percent, though certain professional services such as legal, accounting, or engineering fees paid to individuals sit at three percent as well. Rental payments to an individual are typically withheld at five percent. Advertising fees are generally withheld at two percent regardless of whether the recipient is an individual or a company. Transport fees are generally withheld at one percent. Prizes and competition winnings attract higher rates. These are general figures based on Revenue Department guidance, and specific circumstances can affect the applicable rate, so verifying with a tax professional for your particular payment types is always worthwhile.

Payments That Do Not Require Withholding

Not every payment triggers a withholding obligation. Purchases of goods, for instance, do not generally require withholding tax unless a service component is bundled in. A company buying stock from a supplier does not deduct withholding tax on that purchase. Similarly, some payment thresholds and exemptions exist, and certain government entities are exempt from having tax withheld. One area that trips up foreign business owners in Thailand is software licensing and royalty payments, which do attract withholding tax and must be reported correctly. Understanding where the line sits between a goods purchase and a service payment matters a great deal, because the consequences of getting it wrong fall on the payer.

What Happens If You Miss a Filing or Under-Deduct

Failing to file PND.3 or PND.53 on time carries a surcharge of one and a half percent per month on the tax that should have been remitted, calculated from the due date. There is also a penalty for late filing. If you failed to withhold at all, the Revenue Department can assess the full withholding tax amount against the payer, plus those surcharges and penalties. In practice, this means that a business which paid a service provider in full without deducting anything may end up paying both the full invoice amount to the provider and the withholding tax amount again to the Revenue Department, out of its own pocket, along with penalties on top. This is precisely what happened to the company in our opening example, and it is an expensive lesson in a regulation that is straightforward once you know what to look for.

Getting It Right From the Start

The simplest way to stay on top of PND.3 and PND.53 obligations is to identify at the point of contracting whether your payee is an individual or a juristic entity, confirm the type of payment and the applicable rate, and build the withholding calculation into your payment process before any money moves. Collect the tax identification number from your payee as standard practice. Many businesses in Koh Samui and across Thailand outsource this monthly filing to an accounting firm, which handles the preparation and submission of both forms as part of a general compliance retainer. For foreign-owned companies especially, where the owner may not speak Thai and may be unfamiliar with Revenue Department processes, this is often the most practical and cost-effective approach. The cost of getting it wrong consistently outweighs the cost of getting proper support from the beginning.
