Does your payroll outsourcing service also handle Workmen's Compensation Fund registration for expat employees — Deadlines are the substance here: Revenue Code returns go to the Revenue Department on each form’s own cycle, financial statements to the Department of Business Development, and contributions to the Social Security Office monthly. Employers must register staff with the Social Security Office and remit monthly contributions under the Social Security Act. Withholding tax is remitted by the 7th of the following month, extended for e-filing under the applicable notification. Names must be spelled identically across every document and match the passport or Thai ID card, otherwise a change-of-name record has to be attached. A divorce by mutual consent is registered at the district office, whereas a contested divorce requires a final judgment. Trademarks are registered with the Department of Intellectual Property on a first-to-file basis. A foreign business licence is assessed against the schedules to the Foreign Business Act B.E. 2542. One team handles translation, interpreting, attestation, police clearance, visas and work permits, and sets out the steps and required documents in writing before starting.
“Does your payroll outsourcing service also handle Workmen's Compensation Fund registration for expat employees?” falls within an end-to-end service that combines document preparation, translation, signature certification, consular legalisation and coordination with the destination mission into a single file. The people who search for it are usually preparing a filing against a fixed deadline, recovering from a rejected submission and trying to identify the missed step, or coordinating documents for several people at once.
In practice, each step sits with a different body: the issuing office, the Notarial Services Attorney, the Department of Consular Affairs, and the destination country’s diplomatic mission. Knowing which body owns which step makes it possible to judge how many stages a bundle needs, and which of them cannot be corrected without starting again.
This is a baseline set. Individual receiving authorities may add requirements, so confirm with the destination body first.
Record how many stages each document needs, who certifies it, and what must finish first, so no step has to be redone.
Check personal names, company names, addresses and dates across the whole bundle before any certification begins.
Original → translation → signature certification / legalisation → destination mission. Doing these out of order forces a restart.
Verify the number of sets, the seals, the binding, and that issue dates are still within the destination’s validity window.

| Thailand’s Apostille status | Thailand acceded to the Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027. No Apostille is issued in Thailand before that date. |
