I. What Is LTR Highly Skilled Professional?
The Highly Skilled Professionals category under Thailand’s LTR Visa (Long-Term Resident Visa) is mainly aimed at foreign professional talent working in Thailand’s target industries, specific professional fields, higher education, research, professional training, or government agencies.
This category differs from Work-from-Thailand Professional. The core of Highly Skilled Professional is that the applicant has an actual work arrangement in Thailand: this can mean an employment contract with a Thai company, being posted to work in Thailand by an overseas employer, or working at a higher education institution, research institution, professional training institution, or government agency in Thailand.
Qualifying applicants can obtain LTR residence for up to 5+5 years and can apply for a Digital Work Permit. LTR also replaces the standard 90-day reporting with once-a-year reporting, and waives the usual re-entry permit requirement. Highly Skilled Professionals who meet specific tax conditions may also qualify for a 17% personal income tax rate on their Thai employment income.
II. Highly Skilled Professional Requirements
1. Must Have a Qualifying Work Arrangement in Thailand
The applicant must provide an employment or service contract with a Thai or overseas company, with an assignment to work in Thailand; alternatively, working at a higher education institution, research institution, professional training institution, or government agency in Thailand is another route.
So a situation where someone is simply employed by an overseas company and works remotely while in Thailand should not be classified directly as Highly Skilled Professional. This kind of situation should generally be compared first against Work-from-Thailand Professional.
For private-sector applications, the BOI’s latest documentation further examines the actual nature of the Thai company’s business, including the company profile, work processes or operating model, and the latest audited financial reports, to determine whether the company and position meet LTR’s target industry requirements.
2. The Job Must Fall Within a Target Industry or a Designated Professional Field
The target industries currently covered by the BOI include automotive, electronics, affluent tourism, agriculture and biotechnology, transportation and logistics, automation and robotics, aerospace, biofuels and biochemicals, petrochemicals and chemicals, digital, medical, defense, industries directly supporting the circular economy, and International Business Centers (IBC).
Besides the industries above, the system also retains a “specific expertise” pathway. For example, R&D and advanced technology, vocational or higher-education teachers, AI/automation/robotics applications, digital systems planning, financial or market analysis and advisory, environmental and energy management, startup incubation and innovation ecosystems, alternative dispute resolution, and trade and investment promotion work carried out by foreign chambers of commerce or related organizations may all be considered.
So eligibility should not be judged by job title alone. For example, a title such as “Marketing Manager” on its own is not sufficient proof of eligibility — what matters is what business the company is in, the applicant’s actual job duties, and whether these correspond to a BOI-designated industry or area of expertise.
3. How Is the Income Threshold Calculated?
In general, applicants must demonstrate an average personal income of at least USD 80,000 per year for the two years before applying.
If average annual income is between USD 40,000 and USD 80,000, applicants must additionally hold a master’s degree or above in a science- or technology-related field, or have specific professional expertise relevant to their field of work in Thailand — either qualifies under the BOI’s governing announcement. A November 2025 BOI document checklist lists only the master’s-degree route, but the underlying announcement, which controls, also accepts the professional-expertise route.
If the applicant is employed by a public university, public research institution, public professional training institution, or other government agency, the minimum personal income requirement may be waived.
In addition, Highly Skilled Professional currently has no fixed five-year work experience requirement. The BOI’s latest documentation lists past employment experience and professional achievements as supporting materials to be provided as relevant, rather than a uniform requirement for every applicant to hold a specific number of years of experience.
4. Health Insurance or Financial Security
Applicants must also meet the health coverage requirement. This can be health insurance covering hospitalization and medical costs in Thailand of at least USD 50,000, generally with at least 10 months of coverage remaining at the time of qualification approval; or qualifying Thai Social Security.
If neither of these two options is used, applicants can instead provide at least USD 100,000 in bank deposits held in their own name, proven to have been maintained continuously for at least 12 months at the time of application. Travel insurance and pure life insurance without a medical component are not accepted.

III. Highly Skilled Professional Application Process
Step 1: First Confirm the Employer, Job Content, and Income
Before formally applying, the most important thing is not to first prepare a large volume of personal documents, but to first confirm three things: whether your employer/institution is eligible, whether the actual work falls within a target industry or designated expertise, and which income qualification route applies.
This is especially important for private-sector applications — simply looking at the company name or its BOI Promotion status is not enough. The BOI assesses eligibility based on the company’s main business and the applicant’s actual job duties.
Step 2: Submit the Qualification Endorsement Online
LTR applications must be submitted through the BOI’s official online system; paper applications cannot be submitted directly to the LTR Unit.
Applicants need to upload their passport, income documents, CV, professional qualifications, employment and company background, and health insurance or alternative financial proof. There is currently no BOI processing fee for the Qualification Endorsement itself.
Once all necessary documents and any follow-up supplementary materials have been fully submitted, the BOI’s published qualification review processing time is about 20 working days.
If relevant government departments need to confirm whether the company’s business falls within a target industry, or the applicant’s professional capability, the actual time may be extended.
Step 4: Obtain the LTR Visa Within 60 Days
Once the qualification is approved, the applicant must complete pre-issuance data updates and pre-checks, and must obtain the LTR visa within 60 days of the Qualification Endorsement Letter being issued.
Applicants who are in Thailand can currently process this at the Thailand Investment and Expat Services Center (TIESC) in Bangkok, located at One Bangkok; applicants outside Thailand can process it through the relevant Thai embassy/consulate or the E-Visa system as applicable.
Step 5: Obtain the Digital Work Permit
Highly Skilled Professionals working in Thailand must apply for a Digital Work Permit as required.
Current official requirements state that LTR holders working for a Thai entity should apply immediately after obtaining LTR, or before formally starting the relevant work. The Digital Work Permit is generally applied for through the LTR system, with a published processing time of about 3–5 working days; once approved, it is collected at the TIESC at One Bangkok.
IV. What Are the 2026 Application Fees?
The Qualification Endorsement stage is reviewed by the BOI free of charge.
Once eligibility is approved, if the LTR visa is issued at TIESC in Thailand, the current government visa fee is THB 50,000 per person. If issued through an overseas Thai embassy/consulate or the E-Visa system, the fee is handled according to the applicable location and local currency.
If a Highly Skilled Professional needs a Digital Work Permit, the current government fee is THB 3,000 per year.
So, based on government fees alone, a main applicant processing this within Thailand should generally budget for a THB 50,000 LTR visa fee plus a THB 3,000 per year Digital Work Permit fee. If dependents are included, each dependent’s LTR visa must be processed and paid for separately.
V. Main Application Documents
1. Passport and Personal Information
Under the BOI’s latest documentation requirements, the passport for LTR generally needs at least 6 months of remaining validity and at least two blank pages. Scanned documents must include the personal information page and all pages bearing Thai immigration stamps.
2. Proof of Income Over the Past Two Years
The BOI mainly accepts official personal income tax filing records, such as a tax return from the relevant country.
If the applicant has worked in a country with no personal income tax system, payroll slips and bank statements may be provided as proof of income as required, and notarization may be necessary in some cases.
3. CV, Education, and Professional Qualifications
The CV needs to clearly describe education, professional background, and the professional capability relevant to the current work arrangement in Thailand.
For the general USD 80,000 income route, a degree is not a uniform mandatory condition; but if using the USD 40,000–80,000 route, education/professional qualification requirements need to be specifically checked.
Research projects, publications, intellectual property, professional certifications, awards, and other achievements can also serve as supporting documents for specialty or expertise.
4. Employment and Company Documents
Private-sector applications generally need to provide a Thai company’s Employment Letter, or an Employment Agreement for work that has not yet started, along with a Company Profile and the latest financial reports.
The Employment Letter must clearly state the position, start date, and end date of employment, and the BOI’s latest checklist requires that such letters generally not be dated more than 3 months before the application date.
If a Digital Work Permit is involved, a WP.46 Employment Certificate is also used, along with the company’s affidavit, shareholder register, VAT documents, company tax information, or applicable industry licenses.
5. Criminal Record Check
A criminal record check is not a fixed document that all applicants must proactively submit at the first step.
The BOI’s latest checklist lists it as a case-by-case Additional Document. If requested, applicants may submit a criminal record check issued by the police of their nationality or country of residence, generally no more than three months old, or a qualifying Thai Police Certificate.
6. Documents Not in English or Thai
Documents not in English or Thai generally require a certified or notarized English or Thai translation.
VI. Frequently Asked Questions
Q1: I am employed by an overseas company, but the company has assigned me to work in Thailand — can I apply?
Possibly. BOI rules allow applicants to sign an employment or service contract with a Thai or overseas company, but there must be an assignment to work in Thailand, and the work and business activity must still meet the target industry or designated expertise requirement. This is different from “living in Thailand while working purely remotely for an overseas company.” The latter is generally closer to Work-from-Thailand Professional.
Q2: Do I need a technology or engineering background?
Not necessarily. Highly Skilled Professional covers more than just technology and engineering. Besides digital, AI, medical, aerospace, and biotech industries, the BOI also covers higher/vocational education teachers, financial or market analysis and advisory, environmental energy, startup ecosystems, alternative dispute resolution, and some trade and investment promotion professions. What really needs to be confirmed is whether your actual job duties correspond to a BOI industry or expertise definition.
Q3: I only earn USD 50,000 a year — can I still apply?
Possibly, but not on income alone. The general standard is an average of USD 80,000 per year over the past two years. If income is between USD 40,000–80,000, applicants must also hold a science- or technology-related master’s degree or above, or have professional expertise relevant to their field of work in Thailand — either route qualifies under the BOI’s governing announcement.
Q4: Does the 17% tax rate apply automatically once you get LTR?
No. The 17% rate is a specific tax benefit for Highly Skilled Professionals, but not all HSP holders automatically have all their income taxed at 17% once they receive the visa. Under Revenue Department rules, the benefit mainly applies to Section 40(1) employment income earned by a qualifying Highly Skilled Professional from employment with a company or juristic person in a target industry. The employer must submit information on qualifying employees to the relevant Revenue Office, the benefit applies from the point the tax authority confirms the relevant notification, and the individual must also file P.N.D.95 as required.
So applicants working at a public university, government agency, or with other sources of income should not assume that all their income qualifies for the 17% rate.
Q5: Is a Highly Skilled Professional’s overseas income also tax-exempt in Thailand?
The foreign-sourced income exemptions available to the other three LTR categories cannot be directly applied to Highly Skilled Professional. Royal Decree No. 743 provides a specific foreign-sourced income exemption for Wealthy Global Citizens, Wealthy Pensioners, and Work-from-Thailand Professionals, whereas HSP’s main tax benefit is the 17% rate on qualifying Thai employment income.
So if there is also overseas investment, dividend, consulting, or other foreign income, it still needs to be assessed separately based on Thai tax residency status and the source of income.
Q6: Can I bring my spouse, parents, and children?
You can currently bring your legal spouse and legal children under 20, with a maximum of 4 dependents in total. BOI has announced plans to expand eligible dependents to include parents and remove this cap, but the change awaits implementation by Thailand’s Ministry of Interior and is not yet in effect. If dependents wish to work in Thailand, they still need to separately arrange the corresponding work permit — obtaining a dependent LTR does not automatically grant all work rights.
Q7: Will LTR become invalid after changing jobs?
Not necessarily, but it needs to be handled in advance. If a Highly Skilled Professional changes Thai employer, and the new company’s business still meets the LTR target industry requirement, the BOI can process an Employer Change, and it is not necessarily required to cancel the entire LTR. Official requirements state that holders should notify the LTR Unit at least 1 month before ending their existing employment. If the new company does not meet the LTR target industry eligibility, the existing HSP LTR must be terminated.
Q8: Do I still need to report every 90 days?
No, reporting under the standard TM.47 90-day cycle is not required. LTR holders who remain continuously in Thailand for a year without leaving instead submit TM.95 annual reporting. If they leave and re-enter during that time, the next annual reporting deadline is recalculated from the most recent re-entry date. However, the address-related TM.30 requirement still applies.
VII. Common Misunderstandings
Misunderstanding 1: Any high-earning professional can apply for HSP
Income is only one of the requirements. The other, equally important test for Highly Skilled Professional is whether the applicant’s work arrangement in Thailand falls within a target industry or designated area of professional expertise. Even if income is far above USD 80,000, if the company and job content do not correspond to BOI’s conditions, high income alone cannot secure eligibility.
Misunderstanding 2: Working remotely for an overseas company also qualifies directly for HSP
This cannot be generalized. An overseas company’s employee can only apply for HSP if there is a qualifying assignment to work in Thailand. If the person simply lives in Thailand while working entirely for an overseas employer, they should look at Work-from-Thailand Professional first.
Misunderstanding 3: The LTR visa itself is a work permit
No. Highly Skilled Professional can apply for a Digital Work Permit, but the visa and the work permit remain separate government processes.
Misunderstanding 4: All of an HSP’s income is taxed at 17%
Also incorrect. The 17% benefit has specific employer, income-type, and tax-filing conditions. Whether other income is subject to the general Thai tax rate needs to be determined separately.
VIII. Summary: Start With “Where You Work, What You Do, and How Much You Earn”
To assess whether Highly Skilled Professional suits you in 2026, start with three questions.
First, do you already have a Thai company, a qualifying institution, or an overseas company’s assignment to work in Thailand?
Second, does the company’s business and your actual job responsibilities correspond to a BOI target industry or designated expertise?
Third, is your average personal income over the past two years at least USD 80,000; and if it is only USD 40,000–80,000, do you hold the additional professional qualification accepted by the BOI?
If these three parts line up, the application direction becomes much clearer once you move on to preparing company documents, income proof, the Digital Work Permit, and tax arrangements.
