The core answer
A "freelancer" and an employee are two different legal relationships, and the label in the contract does not decide which one you have. What decides it is how the work is actually done. A person who delivers an agreed result with their own methods, time and tools is a contractor. A person who works the company's hours under the company's orders is, in substance, an employee, even if everyone calls them a freelancer.
The rule (law). The Civil and Commercial Code separates hire of service (s.575, the person works for the employer and is paid for the time worked) from hire of work (s.587, the contractor completes a result and is paid for it). The Labour Protection Act B.E. 2541 defines an employee as a person who agrees to work for an employer in return for wages, by whatever name called. A contract can be written, oral or implied. Where the relationship is employment, the Act applies, including severance under s.118.
Our practical view. The risk grows with duration and integration. A freelancer used for years, on fixed days, inside your team, using your equipment, and paid the same amount every month, looks like staff. The cheapest fix is to decide the structure at the start: either hire the person, or write a real project contract and run the relationship that way.
1. What is the difference between hire of work and hire of service?
| Hire of service (s.575) | Hire of work (s.587) | |
|---|---|---|
| Party | Employee (ลูกจ้าง) | Contractor (ผู้รับจ้าง) |
| What is promised | Work for the employer | A finished result |
| What is paid | Wages for the time worked | A price for the result |
| Who directs the work | The employer | The contractor |
| Governing rules | Labour Protection Act plus the Code | The Code's hire-of-work chapter |
For hire of work, the client may also end the contract before the work is finished by compensating the contractor for loss (s.605). That flexibility is a feature of contracting. It does not carry over to employment, where dismissal triggers severance rules.
2. What signs make a "freelancer" look like an employee?
The statute states the principle, not a checklist. In practice, lawyers and labour authorities look at control and integration. These are the factors we weigh, drawn from the statutory definitions above and our practice. They are indicators, not a legal test with a pass mark.
| Factor | Points toward employee | Points toward contractor |
|---|---|---|
| Control | Company tells them how to do the job | Person chooses the method |
| Time | Fixed hours or days, attendance expected | Deadlines and milestones only |
| Place and tools | Company desk, laptop, email, uniform | Own place and own tools |
| Pay pattern | Same amount every month, regardless of output | Paid per project, milestone or deliverable |
| Exclusivity | Cannot take other clients | Free to serve other clients |
| Substitution | Must do the work personally | May send a substitute or team |
| Integration | Has a title, a manager, leave approvals | Sits outside the org chart |
| Duration | Open-ended, no defined project | Defined scope and end |
No single factor settles the question. A court looks at the whole picture. We have not cited a Supreme Court decision here, because the point of this guide is the principle; ask us if you need case support for a specific dispute.
3. What can it cost if the freelancer is treated as an employee?
If the relationship is employment, the Labour Protection Act applies in full. The main exposures:
- Severance (s.118). After 120 consecutive days of work, dismissal triggers severance on a scale that reaches 30, 90, 180, 240, 300 or 400 days of final wages, depending on length of service. "Dismissal" is defined broadly: any act by which the employer stops giving work and stops paying wages, whatever the reason, including the end of a contract. A fixed-term employee whose employment ends on the agreed date is excluded.
- Social security. An employer must register employees with the Social Security Office and pay contributions. The Office's guidance for Section 33 insured persons covers employees of employers. We have not verified the current rates and ceilings here; check with the Social Security Office.
- Tax filing. Salary income is reported on PND.1 and summarised on PND.1 Kor, which the form says is due in February. Treating an employee as a contractor means the withholding method was wrong.
- Other entitlements. Overtime, leave, holiday pay and wage rules attach to employees. How much applies depends on the facts, which is why we do not give numbers.
Do not treat this as an automatic or retroactive bill. Whether and how much a person can claim depends on the facts and on proof. A lawyer should review the history before you end a long relationship.
4. How does tax differ for a freelancer and an employee?
| Employee | Genuine contractor | |
|---|---|---|
| Income type | Salary (employment income) | Fee for work or service |
| Withholding | PND.1 monthly withholding | PND.3 if the payee is an individual |
| Rate | Progressive, set by payroll rules | Rate by income type, commonly 3% for contract work or service fees |
| Year-end | PND.1 Kor and withholding certificate | Withholding certificate (50 bis) |
The Revenue Department's manual states that 3% applies to contract work and to service fees (order Tor.Por. 4/2528). A reduced 1% rate for payments made through the e-Withholding Tax system ran until 31 December 2025 (B.E. 2568), and the Cabinet approved an extension on 16 June 2026; check the Revenue Department for the rate in force before you rely on it. The tax is paid to the Revenue Department within 7 days after the end of the month in which you pay. Using the contractor method for someone who is really an employee does not cure the labour risk. It can add a tax question on top.
5. How do I structure a genuine contractor arrangement?
Make the paperwork match the facts, and the facts match the paperwork. We suggest:
- Scope. Define the project or deliverables, not "general support".
- Pay by result. Fee per deliverable or milestone, with a clear acceptance step.
- Independence. The contractor chooses method and schedule within the deadline. No attendance rules.
- Own tools. They supply their own equipment and software where practical.
- Other clients allowed. Add a confidentiality clause rather than an exclusivity clause.
- Substitution. Allow a qualified substitute, subject to confidentiality.
- Term and exit. A defined end date or project completion, with termination terms.
- Invoices and withholding. The contractor invoices; you withhold and issue a certificate.
- Then behave accordingly. Do not give them a company email title, a manager, leave approvals or monthly "salary".
If you need someone on your hours, in your team, doing open-ended work, the honest structure is an employment contract. The same applies if you route the person through a middleman: do not re-label staff as contractors by adding a company in between. For people supplied by an outside agency, see our guide on outsourced labour and subcontracted workers.
6. Who owns the work a freelancer produces?
Ownership is a separate question from employment status, and it is the one most often left out of a freelance contract. Under the Copyright Act B.E. 2537 (we read an unofficial reproduction; check the official text):
- Employee work (s.9). Copyright generally belongs to the employee who created it, unless the parties agree otherwise in writing. The employer may publish the work for the purposes of the employment.
- Commissioned work (s.10). Copyright belongs to the person who commissioned the work, unless otherwise agreed.
- Transfer (s.17). A transfer of copyright must be in writing and signed by both parties. If no term is stated, it is deemed to last 10 years.
- Moral rights (s.18). The author keeps the right to be credited and to object to distortion, which an assignment does not remove.
Because the default rules differ for employees and contractors, and because s.17 requires a signed writing, put an IP clause in every freelance contract: who owns the result, whether you get an assignment or a licence, the territory and duration, and the right to modify. For software, see software development contracts and source code.
Hypothetical example
Hypothetical example. A design studio engages a designer "as a freelancer" for three years. The designer works Monday to Friday at the studio, uses a studio laptop, answers to the creative director, takes no other clients, and is paid 40,000 baht on the 30th of each month with 3% withheld. When the studio ends the arrangement, the designer claims employment status and severance. On these facts the label offers little protection, because control, fixed hours, tools and fixed monthly pay all point to employment. Had the studio paid per project, let the designer work on their own schedule and tools, and allowed other clients, the picture would look different. Outcomes depend on evidence; this example is only an illustration.
Checklist before you hire or renew a freelancer
- Can the person decide how and when to do the work?
- Is pay linked to deliverables, not to time?
- Do they use their own tools and workplace?
- Can they work for others, and can they send a substitute?
- Is there a defined scope and end date?
- Does the contract assign or license the IP in writing, signed by both sides?
- Are you withholding and filing correctly for the income type?
- If this is really a staff role, is there a proper employment contract and social security registration?

In short: the contract label does not decide whether someone is a freelancer; control, hours, tools and pay pattern do, so choose your structure first and then run it consistently.
