With the second largest economy in Southeast Asia, today Thailand is often considered a great land for business opportunity in this part of the world. The country boasts an array of natural resources, a hard-working and efficient workforce, and an ideal strategic position. Bangkok’s Suvarnabhumi International Airport (BKK) is easily accessible from airports across the world, with direct flights available from cities such as London, Amsterdam, Hong Kong, and Dubai.

If you’ve made the decision to expand your business to Thailand, it’s pivotal that you understand and achieve compliance with Thai HR and payroll law. The country has its own policies regarding sick pay, overtime rates, tax, and pensions among other things – all of which must be properly adhered to.

The experts here at IRIS FMP are equipped to provide guidance and consultation pertaining to your Thai expansion plans, as well as practical solutions relating to international HR and payroll law.

Payroll in Thailand

What tax considerations are there?


Personal Income Tax (PIT)

A Thai employee’s income is taxed according to their salary amount. Anyone earning less than 150,000 baht ($4,930) annually is exempt, and then after this the starting tax rate is 5%. Thai tax rates increase gradually up to the maximum rate of 35% for anyone earning a salary of 5,000,001 baht ($164,348) or more.

In general, tax is withheld from employees when their salaries are paid under a Pay As You Earn (PAYE) system. This then negates the need for employees to file tax forms on an annual basis, however it means employers must submit a Monthly Withholding Tax form. Manual forms must be submitted by the 7th of the following month, or the deadline for online forms is the 15th of the following month. Social Security rates are 5%, and employers are also required to pay into a workplace pension fund for their employees.

For tax purposes, anyone living in Thailand for more than 180 days is considered a resident. Residents must pay tax on their total income, regardless of whether this is from Thai or international sources. Those working in Thailand who have lived there for fewer than 180 days need only pay tax on income derived from within Thailand. Tax must be paid regardless of if you have a work permit or not.

Corporate Income Tax (CIT)

Thailand has entered into a Double Tax Treaty with most other countries worldwide. These treaties are essentially designed to stop a company’s income from being taxed twice (in more than one country).

Thai companies obtaining local and/or international income, and international companies obtaining income from Thailand, are subject to the nation’s corporate tax of 20%. This is the case unless that company has a paid-in capital or total annual income of less than 3,000,000 baht ($98,586). Anything below this will be taxed at a rate of 15%, unless the paid-in capital or total income is less than 300,001 baht ($9859) – in which case the company will be exempt from tax.

Corporate Income Tax is paid twice annually in Thailand. At the end of the first half of the tax year, a tax return must be completed within two months. Then within 150 days after the closing date of the financial year, the second tax return is due.

Employer Must-Dos

Information that must be submitted by companies in Thailand;

  • Monthly Withholding Tax form (WHT)
  • Income Tax Return report for companies (PDN1 K)
  • Semi-Annual Tax Return form (CIT 51)
  • Annual Tax Return (CIT 50)

HR in Thailand

What are the regular working hours in Thailand?

Most working Thai people are expected to work Monday to Saturday. Between Monday and Friday hours are generally 8.30am to 5.30pm with a one hour break for lunch. On Saturdays there is a half day. 48 working hours per week is the maximum.

Vacation, maternity and sickness

In Thailand, employees are entitled to six days of annual leave every year. Conventionally these are taken as single days throughout the year, rather than as block leave. In addition to this, there are 13 national holidays in the country during which employees are not expected to work.

Pregnant women can take paid maternity leave up to the length of 45 days, but are allowed an additional 45 days unpaid.

The number of lawful sick days allowed is generous in Thailand, at 30 days per year. As well as this, employees are entitled to take paid time off for personal reasons such as taking care of family members who are sick.


Most workplaces in Thailand do not supply a written contract, although there is an understanding between employers and employees of certain obligations. This includes a 30 day notice period from either party when an employee leaves.

Unless there has been gross misconduct or criminal activity, employees receive severance pay if they are dismissed. Depending on their length of service, this should be a minimum of one month’s pay.
