Thailand’s LTR visa (administered by BOI, a 10-year renewable multiple-entry visa with a 5+5 year structure) has four categories. Highly-Skilled Professionals (HSP) is the professional-talent track among them — and also the only category eligible for the 17% personal income tax benefit on the benefits list (“HSP only” is the literal wording of the official list). To answer “which professionals can apply,” you need to look at the literal wording of three parallel conditions: income, employer, and the common financial security requirement. This article breaks each one down, then compares HSP with the easily confused Work-from-Thailand Professionals (WFTP) category.
Condition Set One: Personal Income
Average personal income of at least USD 80,000/year over the past two years; or at least USD 40,000/year with a master’s degree in a science or technology field. Two details, read exactly as the official wording states them:
- The measure is “average over the past two years” — not simply meeting the threshold in a single year;
- The USD 40,000 bracket is tied to a master’s degree specifically in a science or technology field — the field itself is part of the condition.
Condition Set Two: Employer — the Core Answer to “Which Professionals”
You must be employed by one of the following types of organization in a targeted industry:
1. A Thai or foreign company;
2. A higher education institution;
3. A research center;
4. A government agency.
There are two layers to the test: the type of employing organization must be on the list, and the organization’s activities must fall within the scope of a targeted industry — the specific list of targeted industries follows BOI’s current announcements, so check it item by item before submitting your application.
Condition Set Three: Common Financial Security
Same choose-one-of-three as the other categories: medical insurance of at least USD 50,000; or Thai Social Security; or a bank deposit of at least USD 100,000 maintained for at least 12 months.
Comparison with WFTP: Similar Income Structure, Different Test Subject
Work-from-Thailand Professionals has a similar income structure (average of at least USD 80,000 over two years, or at least USD 40,000 plus a master’s degree), but the two categories test different things. Reading the wording side by side:
| Comparison Point | HSP | WFTP |
|---|---|---|
| Master’s requirement for the USD 40,000 bracket | Master’s degree in a science or technology field | Master’s degree |
| Employment/employer requirement | Employed by a Thai or foreign company, higher education institution, research center, or government agency in a targeted industry | Employer must be a listed company, or a private company operating for 3+ years with USD 50,000,000 in revenue, or a subsidiary of either |
The conditions for all four categories are independent and cannot be mixed — check each against its own literal wording; you cannot use a qualifying item from one category to make up for another.
What HSP Gets: Benefits Read Item by Item
- 17% personal income tax: the benefits list explicitly states this applies only to Highly-Skilled Professionals;
- Foreign income exemption: listed on BOI’s benefits list; the specific applicable details follow current tax law and regulator rules;
- 90-day reporting changed to once a year; exemption from re-entry permit requirements;
- Digital Work Permit: the list notes that the Work-from-Thailand category is excluded — HSP is not among the excluded categories.
Fees and Process
The processing fee for the 10-year multiple-entry visa issued in Thailand is THB 50,000 per person (fees for issuance outside Thailand differ and can be significantly higher, per the issuing channel’s published rates); maintaining a work permit costs THB 3,000 per year. The official four-step process is: online submission → eligibility review result notified within 20 working days (can be extended if further documents are requested) → pre-approval in 1–3 working days, then book to collect your visa within 60 days of the endorsement letter’s issue date → work permit approval (if applicable) in 3–5 working days.
A Few Misunderstandings
Misunderstanding One: “If your income reaches USD 80,000, you can apply for HSP.”
Three conditions are parallel: income + employer (a designated organization type in a targeted industry) + common financial security — missing any one means you do not meet this category’s conditions.
Misunderstanding Two: “Everyone who gets an LTR enjoys the 17% tax rate.”
The literal wording of the benefits list is that it applies only to Highly-Skilled Professionals — other categories are not within that benefit’s scope.
Misunderstanding Three: “Any master’s degree works for the USD 40,000 bracket.”
HSP’s USD 40,000 bracket is tied to a master’s degree specifically in a science or technology field — compare this with WFTP’s master’s requirement, which does not carry a field restriction; each category follows its own literal wording.
FAQ
Q1: What are the full conditions for HSP?
Three parallel conditions: income (average of at least USD 80,000 over two years, or at least USD 40,000 plus a master’s degree in science or technology) + employment by a Thai or foreign company, higher education institution, research center, or government agency in a targeted industry + choose-one-of-three common financial security.
Q2: What are HSP’s targeted industries?
BOI’s current Announcement No. Por. 3/2568 lists the following targeted industries for HSP:
1. Automotive
2. Electronics
3. Affluent Tourism
4. Agriculture, food and biotechnology
5. Transport and logistics
6. Automation and robotics
7. Aviation, aerospace and space
8. Biofuels and biochemicals
9. Petrochemicals and chemicals
10. Digital industry
11. Medical industry
12. Defense industry
13. Industries that directly and substantially support the circular economy, such as waste-to-energy and water resource management
14. International Business Center (IBC)
15. Other industries, provided the applicant works in a special professional field designated by BOI
Category 15 is especially worth noting. It means the company itself does not necessarily have to fall under one of the first 14 named industries; if the applicant’s work falls within a special professional field designated by BOI, they may still fall within HSP’s scope for review. The current announcement’s listed professional fields include:
- Research and development in targeted industries or technology fields, such as biotechnology, nanotechnology, advanced materials, and digital technology;
- Higher education or vocational education teachers;
- Applying AI, automation and robotics in business operations;
- Planning and developing digital systems to improve enterprise productivity and services;
- Financial or market analysis and advisory services;
- Environmental and energy management;
- Management or advisory work for incubators, accelerators, and innovation/startup ecosystems;
- Alternative dispute resolution services;
- Economic development, trade and investment promotion work carried out by foreign chambers of commerce or overseas trade and investment promotion agencies.
This can be seen as two steps: first, check whether the employer’s main business activity falls within a targeted industry; second, if the company itself does not clearly fall within one of those industries, check whether the applicant’s role falls within a special professional field designated by BOI.
BOI’s current FAQ also explicitly requires that, when determining whether a company meets a targeted industry, the assessment should be based on the company’s primary business operations against Section 3.4 of Announcement No. Por. 3/2568 — not simply the company name, brand positioning, or job title.
For example, an ordinary company might give someone the title “Digital Director,” but if the actual work is just general administrative management, that title alone cannot qualify as Digital Industry; conversely, at a company that is not purely a technology company, if the applicant’s actual responsibilities involve planning AI, automation, or digital systems to improve enterprise productivity, it is worth checking against the special-expertise path under category 15.
In addition, HSP conditions were relaxed in 2025: the previous work-experience requirement is no longer required, and eligibility has been extended to university professors across all fields.
So the focus of the HSP determination is no longer simply “what is your profession,” but:
What organization employs you + what does that organization primarily do + what specific professional work do you actually perform.

Q3: What’s the difference between HSP and WFTP?
The income structure is similar, but the test is different: HSP tests the type and industry classification of your employer; WFTP tests the employer company’s own eligibility (listed / operating 3+ years with USD 50,000,000 in revenue / a subsidiary) — the conditions for each category are independent.
Q4: Who can use the 17% tax rate?
The benefits list explicitly states this applies only to Highly-Skilled Professionals; the specific application follows current tax law and regulator rules.
Q5: How much does the application cost?
THB 50,000 per person for a visa issued in Thailand (10 years); fees for issuance outside Thailand differ and can be significantly higher; maintaining a work permit costs THB 3,000 per year.
Q6: How long does the process take?
Official timelines: eligibility review result notified within 20 working days (can be extended if further documents are requested) → pre-approval in 1–3 working days → book to collect your visa within 60 days of the endorsement letter’s issue date → work permit (if applicable) in 3–5 working days.
