Minimum Wage in Thailand: The Complete 2026 Guide

Thailand’s minimum wage is not a single number. It is a grid. The National Wage Committee sets different daily rates for different provinces, reviewed periodically and adjusted based on local cost of living, labour demand, and economic activity. As of 2026, daily rates range from THB 337 to THB 400 (~USD 9.70 to $11.55), with Bangkok, Phuket, Chonburi, Rayong, Chachoengsao, and Koh Samui at the top of the scale.

The headline wage changes are only part of the 2026 story. Starting 1 January, the social security wage ceiling increased from THB 15,000 to THB 17,500, raising the maximum monthly employer contribution from THB 750 to THB 875. This is phase one of a three-phase reform that will push the ceiling to THB 23,000 by 2032. On top of that, a new Employee Welfare Fund (EWF) is scheduled to launch in October 2026, adding another mandatory contribution layer. For international employers, the cost of hiring in Thailand is going up, and the compliance requirements are getting more complex.

This guide covers the provincial wage grid, the social security reform, total employer costs, overtime rules, income tax, and how an Employer of Record handles Thai payroll compliance.

Thailand’s minimum wage is set per day, not per hour or per month. The Labour Protection Act requires a minimum of 8 hours per day and a maximum of 48 hours per week. Monthly equivalents depend on the number of working days (typically 26 per month).

The THB 400 rate also applies nationally to hotels (type 2, 3, and 4 under the Hotel Act) and entertainment establishments, regardless of province. A hotel in Chiang Mai with a general provincial rate of THB 370 must still pay THB 400 if it falls under the Hotel Act classification. This sector-specific rule catches many employers off guard.

The government’s stated policy target is THB 600 per day by 2027, but the current trajectory suggests a more modest path. The jump from THB 370 to 400 for Bangkok in July 2025 was the most significant recent increase. Whether the 600 target materialises will depend on economic conditions and political dynamics.

This is the change that matters most for international employers. Thailand’s social security contribution rate stays at 5% for employers and 5% for employees, but the wage ceiling used to calculate those contributions increased on 1 January 2026:

For an employee earning THB 20,000/month, the employer’s monthly social security contribution increased from THB 750 to THB 875 in January 2026, an increase of THB 125/month or THB 1,500/year per employee. For a team of 50, that is THB 75,000/year in additional cost, just from the ceiling change.

The reform also increased benefit entitlements: sickness and disability compensation rose from THB 7,500 to THB 8,750/month, maternity benefits from THB 22,500 to THB 26,250 per birth, and the death benefit from THB 90,000 to THB 105,000. Pension benefits also increased for long-term contributors.

Thailand’s mandatory employer social security contributions are among the lowest in Asia at roughly 5 to 6%. For comparison, South Korea is 10 to 11%, China is 30 to 40%, and Vietnam is 21 to 22%. This makes Thailand attractive on total cost, even though the minimum wage itself is not the cheapest in the region.

The Employee Welfare Fund (EWF), originally planned for October 2025 but postponed to October 2026, will add another mandatory contribution for both employers and employees. Details are still being finalised, but early indications suggest rates in the 0.2 to 0.5% range. Combined with the SSF ceiling increase, 2026 is a double-hit year for employer cost planning.

Thailand’s 98-day maternity leave and newly introduced 15-day paid paternity leave (effective 2025) are both recent changes under the amended Labour Protection Act. The maternity benefit is split: the employer pays for 45 days, and the Social Security Fund covers the remaining 53 days at a capped rate. For companies hiring employees internationally, the severance schedule is the most important table to internalise. Thailand’s severance obligations are uncapped and escalate steeply with tenure.

A minimum-wage worker in Bangkok earning THB 10,400/month (THB 124,800/year) falls below the THB 150,000 exemption threshold and pays no income tax. A professional earning THB 30,000/month pays an effective rate of roughly 3 to 5% after personal deductions and the SSF deduction. Thailand’s income tax burden is low by international standards, which makes gross salary comparisons more favourable than they appear.

Thailand’s total employer cost (5 to 6% social security + no mandatory pension beyond SSF) is the lowest in this comparison. Malaysia’s EPF at 13%, Vietnam’s combined social insurance at 21 to 22%, and Singapore’s CPF at 17% all exceed Thailand’s mandatory burden significantly. This makes Thailand one of the most cost-effective hiring markets in Asia for companies that do not need to offer supplementary benefits. The trade-off is that the statutory safety net is thinner, and competitive employers fill the gap with voluntary Provident Funds and private health insurance.

An Employer of Record in Thailand operates as the legal employer on behalf of your company. The EOR holds the Thai entity, registers with the Social Security Office, files monthly contributions, calculates withholding tax, manages the Workmen’s Compensation Fund, and handles statutory leave entitlements. Your company retains day-to-day management of the employee while the EOR owns the compliance stack.

For the 2026 changes specifically, your EOR should have updated the SSF ceiling from THB 15,000 to 17,500 in January payroll, adjusted all contribution calculations accordingly, and flagged the upcoming EWF obligation in October. If your EOR hasn’t communicated these changes proactively, that is a signal. The pros and cons of using an EOR come down to whether the provider actually stays ahead of regulatory changes or simply processes payroll on autopilot.

Thailand does not require a permanent establishment exemption for EOR arrangements, but the legal structure matters. Some EOR providers use their own Thai entity, while others rely on in-country partners. Own-entity EORs give you more control over compliance and data. Partner-model EORs can be faster to set up but introduce a third party into the employment relationship. Either way, the EOR is liable for all statutory obligations including the new SSF ceiling and the forthcoming EWF.
