Payroll Outsourcing Thailand: Your People Stay Yours, the Payroll Work Moves to Our Team
Payroll calculation, statutory filings, bank files and payslips, finished every month on a calendar we agree in advance, by a team that runs Thai payroll every day. Thai and foreign employees, in Thai or English.
1. How our payroll outsourcing service works
Your company remains the employer. Nothing changes for your employees, their contracts or their manager. What changes is who does the calculation, the paperwork and the filings every month.
Stays with you
- Employment contracts and your name as the employer
- Hiring, salaries and benefits, your decisions
- Send the monthly inputs, then review and approve before anything is paid
Moves to our team
- Payroll, tax, social security, Employee Welfare Fund, provident fund
- Payslips, bank file and every report
- Monthly and yearly filings, registrations for new hires and leavers
From 1 October 2026 the Employee Welfare Fund contribution starts, 0.25% each from employer and employee. Our team calculates, reports and files it alongside social security. Nothing extra for you to set up.

7. Why companies hand their payroll to this team
One dedicated payroll officer
Every client has one person who knows your structure. Ask directly, no re-explaining every month.
Parallel run before going live
In the first month we calculate against your latest cycle until the numbers match, then start the live run.
New rules applied in the right month
The team tracks every change that touches payroll and tells you in advance what to prepare, such as the Employee Welfare Fund from 1 October 2026.
Salary data kept away from colleagues
Access is limited to the team responsible, and you decide who approves.

Payroll outsourcing FAQ
We have fewer than 10 employees. Can we use this service?
Yes. One core client group for this service is foreign companies newly set up in Thailand with only a few employees.
Salary data is confidential. How is it protected?
Access is limited to the team responsible for your account, and you decide who approves the monthly report. Moving payroll outside the company also keeps salary data away from colleagues.
Can we start mid-year, or do we need to wait for a new tax year?
Yes. We load year-to-date figures for every employee first so cumulative tax and social security stay correct, then run a parallel calculation against your latest cycle before going live.
Are year-end documents like PND 1 Kor, 50 Tawi and Kor Tor 20 Kor included?
Yes. We prepare the full year-end set, summarised so your accountants or auditors can use it immediately.
We are a foreign company. Can everything be in English?
Yes. We work with foreign clients regularly: all reports and communication can be in English.
Do we need a payroll system or an employee app?
No. The core service delivers PDF payslips by email and takes your monthly inputs by email. If you want employees to view payslips, submit leave and claims through an app, we can source a system for you separately.
Can you pay salaries on our behalf?
Yes. Three options: we prepare the bank file and you upload it, we upload it for you under a power of attorney, or we release all payments after you transfer the total ahead of pay day on the agreed calendar.
Do you handle foreign employees?
Yes, from tax ID and social security registration and hospital selection through to every yearly document for each foreign employee.
What about a bonus or an item that arrives after the cut-off?
It runs as an extra cycle, announced ahead on the calendar.
Do we need to prepare anything for the Employee Welfare Fund?
No. From 1 October 2026 our team calculates, deducts, files and reports it together with social security every month.
