LTR Visa Thailand for Highly Skilled Professionals: eligibility, 17% tax cap, and work permit sequence
Thailand’s Long-Term Resident Visa offers a dedicated path for Highly Skilled Professionals, foreign specialists, executives, and experts employed by approved Thai companies, universities, hospitals, and institutions in BOI-targeted industries.
Unlike the Work-from-Thailand stream for remote overseas employment, this category is for people working inside Thailand for a Thai entity, with a real work permit, tax incentives, and a 10-year visa instead of annual Non-B cycles. At Thai Visa Centre we guide Highly Skilled LTR applications from Bangkok. For the main programme overview see LTR Visa Thailand guide.
Company, university, hospital, or institution in a BOI-targeted industry.
On qualifying Thai employment income for the LTR permission period.
Five-year minimum work experience rule removed under Announcement Por 3/2568.
Typical issuance through LTR system after visa affixation; 3,000 THB/year maintenance.
How to be eligible
You must qualify under the Highly Skilled Professionals stream at ltr.boi.go.th. Your employer must be a Thai company, university, hospital, research centre, or institution in a targeted industry. You need a genuine employment contract with salary and role details, shell arrangements do not pass BOI review.
BOI expects advanced academic or professional credentials matching your role, typically a bachelor’s degree or higher, or equivalent professional certification. Income thresholds are set per industry and role. The five-year minimum work experience rule was removed in January 2025.
Wrong stream warning: Remote-only workers employed by overseas companies should use Work-from-Thailand Professionals, not Highly Skilled LTR.
Highly Skilled vs Work-from-Thailand LTR
These two employment-related LTR streams are frequently confused. The employer location and work permit type determine which stream applies.
| Aspect | Highly Skilled | Work-from-Thailand |
|---|---|---|
| Employer | Thai entity in Thailand | Overseas company |
| Work permit | Full Thai work permit | Digital work permit (remote only) |
| Tax perk | 17% income tax cap | Foreign income rules vary |
| Best for | Hired by Thai firm | Remote for foreign boss |
Tax benefits for LTR visa holders
The headline tax advantage for Highly Skilled Professionals is personal income tax capped at 17% on qualifying Thai employment income for the LTR permission period. Standard Thai progressive rates can reach 35%, the cap is a material saving for high earners.
Tax treatment depends on income type, physical presence, and Revenue Department rules. LTR approval does not automatically exempt all foreign-sourced income. Obtain advice from a qualified Thai tax adviser before relocating. For 2025 rule changes see LTR eligibility eases guide.
Required documents
Highly Skilled cases require employer participation and a complete document pack from both applicant and company. Health insurance meeting BOI minimums, typically USD 50,000+ inpatient coverage: or qualifying alternatives is required.
| Document type | Typical evidence |
|---|---|
| Personal | Passport, degree certificates and professional licences (legalised as required), CV, police clearance if requested, health insurance certificate. |
| Employment | Employment contract with Thai entity, company registration, employer support letter confirming role and LTR sponsorship, payslips and tax evidence. |
| Employer financials | Company revenue and registration proof per BOI sector requirements. |
| Insurance alternative | USD 50,000+ inpatient coverage, Thai social security where applicable, or qualifying bank balance per BOI rules. |
Application process and work permit sequence
Work through these steps in order. Employer coordination is essential from step one, do not register online before your company confirms BOI sector eligibility.
Employer and applicant coordination
Highly Skilled cases require employer participation. Your company should confirm BOI eligibility and support document collection before you register online at ltr.boi.go.th.
Register and select Highly Skilled Professionals
Create account, choose the Highly Skilled Professionals stream, and upload qualification documents. Income thresholds are set per industry and role on the BOI system.
BOI qualification endorsement
Target review approximately 20 working days after complete submission. BOI may request clarifications, respond quickly to avoid delays.
Visa affixation
With endorsement letter, affix LTR at OSS/TIESC (One Bangkok), Royal Thai embassy abroad, or e-Visa channel. Fee in Thailand: 50,000 THB per person for the 10-year visa.
Work permit issuance
Apply for LTR work permit through the programme: typically 3–5 working days after visa issuance. Maintenance fee: 3,000 THB per year.
After arrival compliance
Complete TDAC before every entry, register address via TM30, file annual residence reporting, and maintain insurance and employment conditions for renewal.
Other benefits of Highly Skilled LTR
Beyond tax and work authorisation, Highly Skilled LTR holders receive programme-wide immigration perks. Alternative for EEC-only employers: compare the Eastern Economic Corridor visa if your job is in Chonburi, Rayong, or Chachoengsao.
| Benefit | Practical value |
|---|---|
| 10-year stay | 5 years plus renewable 5 years when employment and programme conditions are maintained. |
| Multiple re-entry | No separate re-entry permit required. |
| Annual reporting | One address report per year versus 90-day reporting cycle. |
| Airport fast track | Expedited immigration at Thai international airports. |
| Dependents | Spouse, children under 20, parents, and other legal dependents per expanded 2025 rules. |
BOI-targeted industries (2025 list)
Your Thai employer must operate in a sector on the BOI targeted industry list. The January 2025 update expanded academic and vocational education providers. Confirm your employer sector on ltr.boi.go.th before registering, not every high salary role qualifies.
- Digital technology and software development
- Health and wellness including hospitals and medical research
- Food and agriculture including agtech and food processing
- Automation, robotics, and advanced manufacturing
- Academic and vocational education providers (2025 expansion)
Shell companies and paper employment arrangements do not pass BOI review. Your employment contract, employer support letter, and company registration must reflect a genuine role with stable salary from the Thai entity.
Highly Skilled LTR vs EEC visa
If your job is in the Eastern Economic Corridor provinces only, compare the EEC visa route: it has a lower upfront bar but is tied to contract length and EEC geography. Highly Skilled LTR suits executives and specialists who want nationwide residence flexibility.
| Aspect | Highly Skilled LTR | EEC visa |
|---|---|---|
| Geography | Anywhere in Thailand | Chonburi, Rayong, Chachoengsao only |
| Duration | 10 years | Tied to contract length |
| Tax cap | 17% on qualifying Thai employment | EEC-specific incentives |
| Upfront bar | BOI qualification required | Lower for EEC-only roles |

Switching from Non-B to Highly Skilled LTR
Professionals already on a Non-Immigrant B visa with a standard work permit may qualify for Highly Skilled LTR if their employer, industry, and income meet BOI criteria. Transition typically requires a new BOI application and coordinated timing so your current permission does not lapse during the switch.
Compare routine Non-B extensions against LTR if you expect to remain in Thailand long term: LTR bundles 10-year visa, work permit, 17% tax cap, and annual reporting in one programme for qualifying profiles.
Common mistakes
- Applying under Work-from-Thailand when employed by a Thai company.
- Employer not on BOI targeted industry list.
- Degree not legalised for your embassy country.
- Assuming 17% tax applies to all income worldwide: it targets qualifying Thai employment income.
- Letting employment contract expire without planning visa transition.
Employer participation requirements
Highly Skilled LTR is not a solo applicant file. Your Thai employer must confirm BOI sector eligibility, provide company registration and financial documents, and issue a support letter confirming your role, salary, and LTR sponsorship before you register online.
Start employer coordination before the applicant builds a personal document pack, missing employer financials are a frequent cause of BOI clarification delays.
