Payroll Outsourcing Thailand — Payroll Handled by a Team That Understands Both the Numbers and Your People
Let your team focus on work that generates revenue, and leave month-end payroll to us.
Workwise's payroll outsourcing covers the full cycle — salary calculation, overtime, social security, withholding tax and year-end documents — run by a team that comes from the recruitment business, and therefore understands that every line on a payslip is about a real person, and never just paperwork.
Who this service fits
1. Companies that can hire on their own, but should not be carrying the back office
Your team is complete, but every month-end HR or accounting loses days to the payroll run, social security filings, tax calculations and payslip questions. Hand that cycle to us and take the time back.
2. Foreign companies newly established in Thailand
A newly registered company with a handful of employees rarely justifies a full-time payroll officer, yet salary, social security and tax must be correct from month one. We run payroll from your very first employee, and communicate with your head office in English.
3. Growing companies where headcount is moving fast
More people means more complexity — multiple overtime structures, shifts, sales incentives, mid-month starters and leavers. When the spreadsheet starts feeling risky, that is the moment to outsource.
What our payroll service covers
- Monthly payroll calculation — salary, overtime, allowances, incentives and deductions per your company's structure
- Social security — calculation, filings, and registering employees in and out
- Withholding tax — monthly PND 1 (ภ.ง.ด.1) filings and the annual PND 1 Kor (ภ.ง.ด.1ก) summary
- Provident fund — contributions calculated and remitted per your fund's rules, where applicable
- Employee documents — payslips, salary certificates, and annual 50 Tawi withholding certificates
- Workmen's compensation fund — annual contribution and the Kor Tor 20 Kor (กท.20 ก) wage report
- Management and accounting reports — a monthly payroll report your accountants or auditors can use immediately
- Answers ready for every question — payslips, deductions and documents summarised clearly for your designated contact, so when employees ask HR, you have the answer to hand immediately
For statutory questions specific to your company's situation, every organisation's conditions differ — talk to our team directly.
How is this different from having an accounting firm run payroll?
Our payroll team comes from the recruitment business. We live with salaries, pay structures and employees' questions all year round, so our work covers more than calculation — monthly summaries your HR can pass straight to employees, a real understanding of market pay from the salary negotiations we handle regularly, employee data managed under the PDPA with a data processing agreement in the contract, and if your team ever needs more people, our recruitment and staffing services are one provider, one contract, one contact away.
As for choosing who runs your payroll — look at the questions your team faces most each month, and pick whoever answers those best.
Getting started

First cycle and monthly delivery
You approve the figures each cycle; we handle the rest, with a monthly summary report.
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?
All payroll data is handled under confidentiality agreements, access is restricted to the responsible team, and reports go only to the contacts you designate. Many companies outsource payroll for precisely this reason — to keep salary data out of wider internal circulation.
How is this different from Staffing & Outsourcing?
With Payroll Outsourcing, employees remain employed by your company and we handle only the back office. With Staffing & Outsourcing, Workwise is the legal employer, covering contracts, benefits and payroll in one. If you are not sure which fits, tell us your situation and we will help you choose.

Can we start mid-year, or do we need to wait for a new tax year?
You can start mid-year. We design the migration so tax and social security running totals carry over correctly, with one parallel test cycle so the numbers are right from the first month.
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.
