Director's Fees vs Salary in Thailand: Tax and Reporting Guide

When a foreign national takes a director role in a Thai company, one of the first questions that comes up is how they should be paid. Should it be a salary? Director's fees? Both? The answer matters more than most people realise, because the two payment types are treated differently under Thai tax law — in terms of how they are classified, how they are reported, and what obligations they trigger for both the individual and the company. To make this concrete, let us walk through a realistic scenario involving a foreign director of a small Thai limited company.

The Scenario: Marcus Takes a Director Role

Marcus is a German national who co-owns a small import and trading company registered in Thailand. He holds a director position and is actively involved in day-to-day operations. His Thai accountant asks him a straightforward question: do you want to receive a monthly salary, quarterly director's fees, or some combination of both? Marcus assumes the answer is mostly a matter of preference. It is not.

The distinction between salary and director's fees is not just administrative. It determines which tax category applies, how the company withholds tax, whether the payment triggers social security obligations, and how income is declared at year end. Getting this wrong can result in incorrect withholding, penalties, and complications during a Revenue Department audit.

How Salary Is Classified and Taxed

In Thailand, salary paid to a director who also functions as an employee is classified as assessable income under Section 40(1) of the Revenue Code. This is employment income. It is subject to personal income tax at progressive rates, which currently range from zero percent on income up to 150,000 baht annually up to 35 percent on the portion above five million baht. The company must withhold tax monthly using the standard withholding calculation for employment income, and the director receives a withholding tax certificate at year end.

Salary also brings social security into the picture. If Marcus is employed as a staff member with a work permit and receives a regular salary, both he and the company contribute to the Social Security Fund — currently calculated as a percentage of monthly wages up to a statutory ceiling. This is a real cost that needs to be factored into payroll planning. For foreign directors, the work permit question is closely tied to the salary arrangement, so these two issues cannot be considered separately.

How Director's Fees Are Classified and Taxed

Director's fees fall under Section 40(2) of the Revenue Code, which covers income from positions or services. This is a separate classification from employment income. The practical difference at the withholding stage is significant: the company must withhold tax at a flat rate of three percent on the gross fee at the time of payment. This is not a progressive calculation — it is a flat withholding applied immediately.

It is important to understand that this three percent withholding is not the final tax. When Marcus files his personal income tax return at the end of the year, all of his Thai-sourced assessable income — including director's fees — is aggregated and taxed at the progressive rates applicable to his total income. The three percent withheld is credited against his final liability. So if his marginal rate works out to 25 percent on that portion of income, he will owe the difference. The withholding is simply a prepayment mechanism, not a lower tax rate.

What the Reporting Obligations Look Like in Practice

For the company, salary payments generate monthly withholding obligations reported on Form PND 1, and a year-end summary on Form PND 1 Kor. Director's fees, on the other hand, are reported on Form PND 3 for individual recipients, which is filed monthly by the fifteenth of the following month whenever a payment is made. These are separate forms with separate filing cycles, so a company paying Marcus both a salary and director's fees in the same month must file both PND 1 and PND 3 correctly.

If the company misclassifies director's fees as salary — which does happen — the withholding calculation will be wrong, the wrong form will be filed, and the payment history will not match what Marcus declares on his personal return. This kind of discrepancy can attract attention during a Revenue Department review, particularly if the company is also subject to VAT audits or transfer pricing scrutiny.

The Work Permit and Social Security Dimension

Marcus's situation gets more interesting when you factor in his work permit. In Thailand, a foreign national who is employed and receives a salary is required to hold a valid work permit. Director's fees can sometimes be paid without a work permit in circumstances where the director is not performing work in Thailand in the conventional employment sense, though this is a nuanced area and the practical reality depends on how the role is structured and how immigration and labour authorities view the arrangement.

Social security contributions are linked to employment income under Section 40(1). Director's fees under Section 40(2) do not automatically trigger social security obligations in the same way. For Marcus, this might reduce the total cost of a fee-based structure compared to a salary, but it also means he does not accumulate social security coverage or entitlements for those periods. This is worth considering if he plans to remain in Thailand long term.

Choosing the Right Structure

There is no universally correct answer for how a director should be paid. The right approach depends on the director's residency status, work permit situation, the nature and regularity of their involvement in the company, and their overall income picture for the year. Some directors receive both a modest salary for their operational role and director's fees for their board-level responsibilities, which reflects the actual nature of two distinct functions.

What Marcus's situation illustrates is that this is not a decision to make informally or by default. The classification of income has downstream effects on withholding, social security, work permit compliance, and personal tax filing. The company's bookkeeping and payroll records need to reflect the correct treatment from the start, because correcting historical misclassification is time-consuming and sometimes costly.

Getting This Right from the Start

If you are a foreign director of a Thai company, or if you manage payroll for a business with foreign directors, it is worth reviewing how these payments are currently structured and reported. Thai accounting and tax rules around director compensation are specific, and the Revenue Code classifications matter. SLF Accounting works with foreign-owned Thai companies in Koh Samui and beyond on exactly these kinds of questions — making sure the structure is correct, the filings match, and there are no surprises at year end.
