Thailand

Overview

Thailand has emerged as one of Southeast Asia's most actively discussed destinations for internationally mobile professionals, digital nomads, and investors following the introduction of the Long-Term Resident (LTR) Visa programme in 2022. Combined with the Thailand Board of Investment's extensive corporate tax incentive framework, the Eastern Economic Corridor investment zone, and Bangkok's growing status as a regional business hub, Thailand now offers a more structured and attractive proposition for foreign individuals and businesses than at any prior point in its modern development.

Long-Term Resident Visa

The LTR Visa, introduced by the Thai government in September 2022, provides a ten-year, multiple-entry visa for qualifying foreign nationals across four categories: Wealthy Global Citizens (with investable assets of at least USD 1 million), Wealthy Pensioners (passive income of at least USD 80,000 per year), Work-From-Thailand Professionals (employed by overseas companies with minimum personal income thresholds), and Highly-Skilled Professionals (working in targeted industries).

LTR Visa holders benefit from a reduced personal income tax rate of 17% on income from foreign employers (in lieu of standard progressive rates reaching 35%), and are entitled to an 80% reduction in the personal income tax rate on certain Thailand-sourced employment income from BOI-promoted businesses. Annual reporting and work permit requirements are streamlined compared to standard non-immigrant visa categories. The visa is administered by the Board of Investment (BOI).

Personal Tax and Foreign Income

Thailand's personal income tax system applies progressive rates from 5% to 35% on assessable income. Under longstanding Revenue Department rules, foreign-sourced income was exempt from Thai tax if not remitted to Thailand in the same calendar year in which it was earned. From 1 January 2024, the Revenue Department issued revised guidance indicating that all foreign-sourced income remitted to Thailand — regardless of the year of earning — may be subject to Thai personal income tax. This change has significant implications for individuals previously relying on the year-of-remittance exemption and should be carefully assessed with a qualified Thai tax adviser before structuring income flows.

Corporate Tax and BOI Incentives

The standard corporate income tax rate in Thailand is 20%. However, companies receiving BOI promotion — granted to businesses in targeted sectors including advanced manufacturing, digital services, healthcare, logistics, and clean energy — may qualify for corporate income tax holidays of between 3 and 15 years, followed by a period at reduced rates. Import duty exemptions on machinery and materials are commonly bundled with BOI promotion certificates.

The BOI application process involves submission of a project proposal, review by the relevant industrial cluster, and approval by the BOI Board. Processing times for straightforward applications are typically 30 to 60 business days. BOI-promoted companies must meet conditions relating to minimum capital investment, employment levels, and technology transfer where applicable.

Company Formation

The standard vehicle for foreign-owned businesses in Thailand is the Thai Limited Company (บริษัท จำกัด). Under the Foreign Business Act (FBA), most service activities are restricted to majority Thai ownership. Foreign investors commonly structure Thai operations using a BOI-promoted company (which may be 100% foreign-owned), a Treaty of Amity company for US nationals, or through a Board of Investment approved holding structure. Total company formation timelines, including registration with the Department of Business Development and relevant regulatory bodies, are typically one to four weeks.

Eastern Economic Corridor

The Eastern Economic Corridor (EEC), located in Chonburi, Rayong, and Chachoengsao provinces east of Bangkok, is Thailand's flagship investment zone. Targeted sectors include automotive, aerospace, digital technology, biotechnology, and smart electronics. EEC investors receive enhanced BOI privileges including extended tax holidays, streamlined permitting, and dedicated visa and work permit procedures. The EEC Authority (EECA) acts as a one-stop service centre for qualifying investments.

Banking

Thailand's banking sector is well-developed for domestic commerce. Major banks include Bangkok Bank, Kasikornbank (KBank), SCB (Siam Commercial Bank), Krungthai Bank, and the Thai operations of Citibank, HSBC, and Standard Chartered. Business account opening for foreign-owned entities requires in-person director presence and documentation of business purpose. Offshore private banking and international wealth management are better served through Singapore or Hong Kong institutions, with Thailand serving primarily as a local operational banking jurisdiction.

Thailand Elite Visa

The Thailand Elite Visa programme, operated by the Thailand Privilege Card Company, provides long-term residence privileges for annual or one-time membership fees. Membership tiers offer five, ten, or twenty-year residence permits with privileges including VIP airport services, health check-ups, and access to government service fast-tracks. The Elite Visa does not confer a work permit and is most suitable for retirees, long-stay tourists, and individuals whose income is generated entirely outside Thailand.
