How to Convert a Thai Contractor to a Full-Time Employee

Hiring a remote contractor in Thailand is the fastest way to hire and expand in Thailand. You don’t need to start a local entity, and you don’t need to go through a lengthy onboarding process. All you need to do is have a service agreement with the contractor, and they will take care of all the statutory contributions and income tax. 

But there might come a point in time where hiring them as a full-time employee would make more sense. If your hired contractor starts to look more like full-time employment, you can absorb them when you establish your own company. However, if you don’t have a legal entity, you run the risk of employee misclassification, which goes against Thailand’s Labour Protection Act (LPA). 

To help avoid legal exposure, we have created this guide on how to convert a Thai contractor to a full-time employee. We will cover two routes, whether you are converting with or without a Thai local entity. 

Why Convert a Contractor to a Full-Time Employee?

If your contractor works fixed hours, follows your instructions day-to-day, and doesn't work for other clients, Thai authorities may consider them as full-time employees. This can happen whether or not they are on a fixed-term contract. When the time is right, converting a contractor can help prevent back-pay claims, penalties and disputes. 

Here are some reasons why employers make the switch from contractor to full-time:

• Legal protection: If a contractor can argue they were effectively an employee the whole time, they may be entitled to severance, back contributions to the Social Security Fund, and other statutory benefits. Converting them cleanly closes that gap.
• Compliance with Thai labour law. Under the LPA, employees are entitled to rights that cannot be contracted away. The longer a misclassified contractor goes unaddressed, the larger the potential liability.
• Talent retention: Full-time employees receive statutory benefits such as health coverage through the SSF, paid leave, and greater job security. These packages are great for employee retention or if you want to attract talent for the long-term. 
• Operational clarity: Employees can be integrated into your systems, given formal responsibilities, and managed under your HR policies. Contractors sit outside that structure in ways that become inconvenient as your team grows.

How to Convert Thai Contractors to Full-timers

The options to convert a Thai contractor depends on whether you have a legal entity in Thailand or not. If you do, you can simply absorb them as a full-time employee with a new indefinite contract. If not, then you can partner with an Employer of Record to be the legal employer of your staff. 

Option 1: Converting with a Thai Entity

If your company already has a registered entity in Thailand, you have the legal foundation to employ workers directly. That said, the process involves multiple agencies, tight deadlines, and ongoing compliance obligations that add up quickly.

Here is what the conversion involves:

• Legal review: Your current contractor agreement needs to be checked against Thai employment law. This identifies any reclassification risk and clarifies what entitlements the contractor may have already accrued. Getting this wrong from the start creates retroactive liability.
• Employment contract preparation: You'll need a Thai-compliant employment contract covering job responsibilities, compensation, working hours, leave entitlements, and benefits. If the worker is a foreign national, the contract must also align with their work permit conditions. After negotiating a new contract, the old contract must be terminated. 
• Authority registration: New employees must be registered with the Social Security Office (SSO) within 30 days of their start date. Foreign employees require updated work permits reflecting the new employment relationship.
• Payroll and statutory contributions
• HR policies and benefits. The employee needs to be brought under your HR framework and provided with all statutory benefits from day one (e.g. paid leave, public holidays, and SSF healthcare coverage).

As a legal entity in Thailand, you can manage all of this in-house with a payroll and HR team. But to make things simpler, you can also partner with RecruitGo to help you manage the entire process on your behalf. 

Option 2: Converting Without a Thai Entity

If your company doesn't have a registered entity in Thailand, you cannot directly employ Thai workers. Thai law requires a local legal entity to hold the employment relationship to employ full-time workers. 

The practical solution is an Employer of Record (EOR). The EOR is a third-party that employs your converted contractor under its own registered Thai entity. Here's what that looks like in practice:

• You share the details: Role, compensation, start date, and any agreed terms. The EOR handles the rest such as preparing a locally compliant employment contract, registering the employee with the SSO, and setting up payroll.
• The contractor is properly informed and onboarded: The EOR ensures the employee understands the transition: who their legal employer is, what their benefits look like, and what changes on their end. Their consent and acknowledgement are documented.
• Payroll, taxes, and compliance run automatically: The EOR calculates and remits SSF contributions, PIT withholding, and WCF premiums on the correct schedules. You receive one consolidated invoice.
• You stay in full operational control: Your converted employee works for you, reports to you, and is part of your team. The EOR handles the legal and administrative layer underneath.
