The e-Work Permit System operated by Thailand’s Department of Employment (DoE) under the Ministry of Labour moved to mandatory use on 28 April 2026. The transitional acceptance of paper filings has now ended, and all new applications, renewals, cancellations and changes must be filed online. This applies to every foreign employer in Thailand, including BOI-promoted companies, and has practical implications for Japanese head offices’ assignment scheduling and HR operations. This article walks through the new flow, the role of ThaiID for identity verification, how this interacts with the BOI Single Window, and five checkpoints Japanese companies will want to revisit.
What Has Changed — Mandatory Use of the e-Work Permit System
Overview
To employ a foreigner in Thailand, two parallel processes are required: a Non-Immigrant B visa (residence status) administered by the Immigration Bureau, and a work permit administered by the Department of Employment under the Ministry of Labour. The change at issue here concerns the work permit side.
The legal basis is the Royal Decree on the Management of Foreigners’ Working (B.E. 2560 / 2017) and its 2018 amendment. The electronic application system itself has been rolled out gradually for several years, but paper filings continued to operate in parallel. The current shift, implemented at the level of DoE notifications, ends paper acceptance at the counters of the Department’s offices.
Scope of the Change
Based on what has been publicly reported:
- In scope: new applications, renewals, cancellations, and changes (including changes of work location, position, name and passport details)
- Who is covered: all foreign employers and foreign workers, including BOI-promoted companies
- Paper filings: from 28 April 2026, the DoE and provincial employment offices reportedly do not accept paper submissions
- Portal: https://eworkpermit.doe.go.th/
Whether some provincial offices will continue to accept paper filings as a transitional accommodation is not clearly confirmed in official DoE communications at this stage. As a practical matter, it is prudent to plan on the basis of full online operation.
How This Compares With Japan
In Japan, employing a foreign national starts with applying to the Immigration Services Agency for a Certificate of Eligibility (COE), followed by visa issuance at the Japanese embassy in the home country and the issuance of a Residence Card upon entry. The “scope of permitted work” is built into the residence status itself; there is no separate work permit.
Thailand, by contrast, runs two parallel tracks: residence status (Non-Immigrant B visa) under immigration law, and work permits under the Ministry of Labour’s Royal Decree. The current change fully digitises the labour-side process only; the immigration side remains administered separately.
ThaiID-Based Identity Verification — Required for Employer Reps, Agents and the Foreigner
A defining feature of the new system is the use of ThaiID, the official electronic ID smartphone app operated by the Bureau of Registration Administration under the Ministry of Interior, as the identity-verification layer.
What ThaiID Is
ThaiID is the official Thai government e-ID smartphone app, widely used for identity verification of Thai nationals. The DoE’s e-Work Permit System uses ThaiID as the identity-verification channel for both the employer-side authorised representative and the foreign worker.
Who Needs to Register
Based on the information publicly available so far, the flow is broadly:
- The employer designates an authorised representative (typically an HR or legal staff member) who registers in the system
- The foreign worker also registers using passport and visa details
- Each completes ThaiID-based identity verification before logging into the e-Work Permit System
- Required documents are uploaded as PDFs
Practical Considerations
A practical question is whether an expatriate can complete ThaiID registration before entering Thailand, and how far identity verification can be progressed in the immediate post-arrival period. Detailed operational guidance is expected to be clarified through subsequent official announcements; in the meantime, it is common for local HR teams or appointed agents to walk the flow through end-to-end as the system stabilises.
BOI-Promoted Companies — The Single Window Remains Available
Companies promoted by the Board of Investment (BOI) can continue to use the BOI Single Window for Visas and Work Permits (swe-expert.boi.go.th / swboi.boi.go.th) for consolidated filings.
The Single Window combines the Immigration Bureau’s Non-Immigrant B visa process and the DoE’s work permit process in a single application path, and has been one of the long-standing operational benefits for BOI-promoted firms. For BOI companies, the route is the BOI’s own platform rather than the general DoE e-Work Permit portal.
In practice, the BOI Single Window is reported to offer expedited processing for promoted companies. Specific turnaround times can shift from period to period, so confirming the latest practice with the relevant BOI office or filing agent is recommended.
Five Checkpoints for Japanese Companies
1. Pre-Registering the Authorised Representative
It is worth confirming internally that HR staff or external agents are properly registered as authorised representatives in the e-Work Permit System and have completed ThaiID-based identity verification. Without a registered representative, work permit filings for new expatriates cannot get under way.
2. Rebuilding the Schedule for New Expatriates
Compared with the paper-era flow, the sequence of “obtain Non-Immigrant B visa abroad → enter Thailand → obtain ThaiID → file the work permit application” introduces ThaiID acquisition as a new timing variable. Where new arrivals are expected to start work immediately on landing, it is worth building extra slack between visa issuance and the work permit application stage.
3. Front-Loading Renewal Cycles
Some practices around exchanging documents at the counter at renewal time are no longer available under a fully online process. Preparing required documents in PDF form in advance, and starting renewal applications earlier than before, is the safer operating posture.
4. Online Filings for Changes in Working Conditions
Position changes, salary changes and changes of work location are also subject to online filing as a rule. Aligning the timing of head-office HR moves in Japan with the corresponding work permit filings in Thailand is best done at an early stage.
5. ID/Password Hygiene and System-Outage Risk
With the process now fully online, internal rules around managing authorised representatives’ credentials, handing over the ThaiID-linked role when HR staff rotate, and dealing with portal congestion are unglamorous but important.
Comparison With Japan’s Residence-Status Regime
Pulling the threads together:
| Issue | Japan | Thailand |
|---|---|---|
| Residence status vs. work authorisation | Combined (scope of permitted work is part of the residence status) | Separated (visa + work permit) |
| Administering authority | Immigration Services Agency | Immigration Bureau + Department of Employment |
| Online filing | Online residence-application system expanding gradually; paper filings still accepted | Paper filings ended (from 28 April 2026) |
| Identity verification | My Number Card used in some flows | ThaiID e-ID app at the centre |
A Japanese head-office HR manager applying purely “Japanese assumptions” to Thailand will easily be tripped up by the visa/work-permit split and by ThaiID’s role. Engaging local HR staff and filing agents early is well worth the effort.
Closing Thoughts — Part of Thailand’s Wider Digital-Government Push
The DoE’s full digitisation of work permits should be read alongside the broader digital-government direction of the Thai administration: the DBD’s data-driven anti-nominee work, the Bank of Thailand’s data-sharing rules and, most recently, the 21-agency MoU on nominee enforcement signed on 29 April. One after another, agency processes are moving to electronic filing and inter-agency data flows.
For Japanese companies, this is a good moment to take stock of paper-based habits and bring local HR operations in line with digital workflows. Registering authorised representatives, sorting out ThaiID, rethinking renewal schedules — practical, one-step-at-a-time work that pays off.
