Thailand Investment Visa: Every Route in 2026
Thailand offers several visas for foreign investors, each tied to a different threshold and profile. The historical "Non-Immigrant IM" visa is still on the books, but the most active routes in 2026 are the LTR Wealthy Global Citizen, the Smart Visa Investor (Smart-I), and BOI-promoted Non-B visas. Choosing the right Thailand investment visa depends mostly on how much you intend to invest and how active you want to be in the day-to-day of your Thai venture.
This guide covers every active route, the exact 2026 thresholds, costs, and the operational differences that matter when you are planning a move.
Non-Immigrant IM (Investment) — Classic Investment Visa
The Non-IM is the legacy investment visa, still issued but rarely the optimal choice in 2026.
- Investment threshold: 10 million THB (about 280,000 USD) in Thai government bonds, fixed deposits with Thai banks, or registered Thai company shares.
- Validity: 1 year, renewable yearly.
- Cost: 200 USD.
- Work permit: Not included.
- Tax flat rate: None.
Mostly used by retirees with significant capital who do not meet the LTR thresholds and do not need to work.
LTR Wealthy Global Citizen — Premium Investor Track
By far the strongest 2026 product for high-net-worth investors.
- Personal assets: Minimum 1 million USD.
- Income: 80,000 USD/yr for the past 2 years.
- Thai investment: 500,000 USD in Thai government bonds, foreign direct investment, or property.
- Validity: 10 years.
- Cost: 50,000 THB.
- Work permit: Included for personal business activities.
- Reporting: Annual instead of quarterly.
The LTR Wealthy Global Citizen track is the cleanest investor route. It rolls up residence, work permission, fast-track immigration, and the right to bring up to four dependants.
Smart Visa Investor (Smart-I)
Aimed at venture-capital-backed investors and angel investors in S-Curve sectors.
- Investment threshold: 20 million THB (about 560,000 USD) in BOI-promoted businesses or in venture-capital firms operating in S-Curve industries.
- Validity: 4 years.
- Cost: 80 USD.
- Work permit: Not required for the holder.
- Reporting: Annual.
Smart-I works well for diaspora investors who want to seed Thai startups and benefit from a clear visa product without the LTR's higher financial bar.
BOI-Promoted Non-Immigrant B + Work Permit
If you set up an actively-managed Thai company in a BOI-promoted sector, the BOI certificate unlocks faster Non-B and work permit processing.
- Investment threshold: Varies by promoted activity (commonly 1–10 million THB registered capital).
- Validity: Tied to BOI certificate; typically 1 year renewable.
- Cost: 80–200 USD for the visa, plus BOI application fees.
- Work permit: Included via BOI fast-track.
- Reporting: Quarterly.
The BOI Non-B route is the best choice for founders who want to run their Thai company day-to-day while the LTR is more passive.
Thailand Privilege (Investor-Friendly Membership)
Although not a true investment visa, the Thailand Privilege programme is often used by investors who want a long-stay base without managing a Thai entity.
- Membership fee: 900,000 to 5,000,000 THB depending on tier.
- Validity: 5 to 20 years.
- Work permit: Not included.
- Best for: Passive investors and retirees who already have offshore portfolios.

Documents Most Investor Visas Require
Across all routes, expect to provide:
- Passport valid 6+ months
- Investment proof (bank statement, broker statement, BOI certificate, share registry)
- Personal tax returns (last 2 years)
- Bank statements (12 months)
- Health insurance with at least 50,000 USD inpatient cover (LTR)
- Police clearance from your country of residence
- Cover letter explaining the investment plan
LTR and Smart-I applications are processed online via the BOI portal; Non-IM and BOI Non-B run through the e-Visa or consulate.
Tax Considerations for Investors
Foreign income remitted into Thailand within the same tax year is taxable for ordinary residents. The LTR Wealthy Global Citizen track exempts foreign income, which is the single biggest tax differentiator across the investor visas.
If you spend 180+ days in Thailand per calendar year, you become a Thai tax resident. Plan accordingly with a cross-border tax adviser before transferring large sums.
Frequently Asked Questions
What is the cheapest Thailand investment visa?
The Smart Visa Investor at 80 USD has the lowest fee, but the 20 million THB investment threshold makes the entry cost high. The Non-IM at 200 USD is cheaper to apply for but ties up 10 million THB.
Which Thailand investment visa is best in 2026?
For most high-net-worth applicants, the LTR Wealthy Global Citizen is the strongest combination of duration, work right, and tax benefit. For active founders, the BOI Non-B is more practical.
Do I need to live in Thailand to keep a Thailand investment visa?
No. None of the investor visas requires a minimum stay. However, becoming a Thai tax resident at 180 days/year may be desirable or undesirable depending on your situation.
Can my family come on a Thailand investment visa?
Yes. The LTR allows up to four dependants; Smart-I allows the spouse and children; the Privilege Visa allows family add-ons at additional cost.
Is property purchase enough for a Thailand investment visa?
For the LTR Wealthy Global Citizen, real estate counts among the eligible 500,000 USD investment. For other categories, government bonds, fixed deposits, or BOI-promoted businesses are usually required.
