Thailand Work Permit Requirements in 2026: The Complete Checklist

Settlr Global TeamAug 13, 20266 min read

Thailand rolls out the welcome mat for foreign talent, then hands you a rulebook. Getting your head around Thailand work permit requirements before you touch a keyboard is the difference between a smooth launch and an expensive scramble. Here is the complete 2026 checklist.

Who needs a work permit

Under the Alien Employment Act, nearly every foreigner performing work in Thailand needs a permit. "Work" is defined generously here: paid jobs, consulting, freelancing and even unpaid roles that a Thai national could do. The rules for a work permit for foreigners in Thailand catch a lot of people off guard, because your Non-Immigrant B visa lets you enter and stay but does not authorise a single hour of work on its own. The two documents come from two different ministries and have to be kept in sync.

A few narrow exceptions exist. LTR visa holders in the Work-from-Thailand category who work only for overseas employers sidestep the traditional permit. Everyone else, company directors very much included, needs one.

The four Thai employees rule

Here is the rule that trips people up. For every foreign work permit, your company must employ four Thai staff registered with Social Security. Want two foreign hires? That is eight Thai employees. The ratio is a maintained obligation, not a one-time box tick, so it has to hold throughout the year.

Two ways to ease it: a foreigner married to a Thai national gets the requirement cut in half, and BOI-promoted companies are exempt from the ratio entirely. That exemption is a big reason BOI promotion appeals to businesses planning to build a foreign team.

The 2 million baht capital rule

Sitting alongside the headcount ratio is a capital requirement. A Thai-majority company needs 2 million baht in fully paid-up registered capital per foreign employee. Foreign-majority companies face a higher bar of 3 million baht per hire. Marriage to a Thai national drops the Thai-company figure to 1 million baht. Either way the ceiling is ten permits per company under the standard rules.

If your capital is not there yet, this is a structuring question worth solving before you hire anyone. Our guide to incorporation capital rules walks through how to set the number correctly from day one.

Documents checklist

Thai officials want evidence from both sides, and an outdated company paper sinks an application just as fast as a missing personal one.

From you, the employee:

Passport valid well beyond the permit term, with blank pages
Non-Immigrant B visa
Three passport photos (3 x 6 cm)
Degree certificates and a CV
Medical certificate from an approved clinic, issued within the last month
Signed employment contract

From your employer:

Company registration and affidavit

Tax ID and VAT registration

Social Security registration and staff list

Recent financial statements

A position necessity letter, if the labour office asks for one

Cross-check names, dates and company details across every form before filing. One inconsistency between your contract and the company affidavit is enough to trigger a resubmission.

Application steps and timeline

The process runs on two parallel tracks, the visa and the permit.

Secure a Non-B visa at a Thai embassy abroad, then enter Thailand on it rather than a tourist entry.

Get your medical certificate from an approved clinic.

Have HR assemble the company pack while you prepare your personal documents.

File both packs at the Department of Employment. Thailand's e-Work Permit system now handles most filings.

Collect the permit booklet once approved.

Bangkok processing usually takes five to seven working days once a complete file lands. Add preparation time and budget four to eight weeks from a standing start. BOI companies get the express lane, with One Stop Service approvals measured in hours rather than weeks. Managing all of this without a last-minute panic is exactly what our work permit services exist for.

Work permit renewal in Thailand

Permits are issued for one year and run alongside your visa extension. Start the work permit renewal at least 30 days before expiry, because a lapse can knock your visa out of alignment too. Renewals need fewer fresh papers than the first application, but expect an updated company affidavit, proof you still meet the Thai-to-foreign ratio, updated personal documents and evidence of personal income tax paid (the PND 91). Government fees are modest, around 1,500 baht. One catch worth remembering: changing employer is not a renewal. It is a brand new application with a new sponsor.

Penalties for working without one

The stakes are real. A foreigner caught working without a valid permit faces fines from 2,000 to 100,000 baht, up to five years in prison, or both. Working outside the scope printed in your booklet, meaning the wrong employer, role or location, counts as a violation too and can void your visa extensions. Employers who hire unpermitted foreigners face their own penalties. This is not a corner worth cutting.

FAQs

Does a Non-B visa let me start work? No. The visa permits entry and stay. You need the approved work permit in hand before performing any duties.

Can a company director work without a permit? No. Directors performing work in Thailand need a permit like any other foreign worker.

How much does a work permit cost? Government fees run roughly 3,100 baht for an initial permit and 1,500 baht for a renewal, plus medical and translation costs. Professional service fees are separate.

Do I need to carry the permit with me? Yes. The permit is a physical booklet you should keep on you whenever you are working.
