What laws govern buying company shares in Thailand in 2025?

Buying company shares in Thailand is governed by the Civil and Commercial Code for private companies and the Public Limited Company Act and Securities and Exchange Act for listed companies. Since 2025, the Electronic Securities Bill requires all share issues and transfers to be registered digitally through SEC-licensed platforms with full audit trails.

How have electronic and regulatory changes affected Thai share purchases?

From June 2025, all share transfers in Thailand must be completed via secure SEC-approved digital platforms. Key changes include mandatory electronic registration, licensed custodianship, instant audit trails, and proposed buyback rules to increase liquidity. These updates enhance transparency and investor protection for both locals and foreigners.

What are the rules for foreign investors buying shares in Thailand?

Foreign investors can buy Thai company shares, but ownership is generally capped at 49% under the Foreign Business Act. To exceed this limit, investors must secure a Foreign Business License (FBL) or Board of Investment (BOI) promotion. Nominee structures are illegal and closely monitored, while certain sectors like agriculture and communications remain restricted.

What ownership and control rules apply when buying Thai company shares?

Ownership gives rights and liabilities, but control depends on pre-emptive rights, special shareholder resolutions, and registration requirements. All share transfers must be registered with the Ministry of Commerce for private companies or the Stock Exchange of Thailand for public ones. Failure to register may invalidate ownership.

How should investors prepare for buying company shares in Thailand?

Due diligence is crucial before buying shares in Thailand. Investors should review shareholder registers, debts, disputes, contracts, financial audits, and regulatory filings. For private companies, check tax and legal claims. For public companies, review market disclosures and compliance reports. A structured checklist helps avoid hidden liabilities.

What steps and documents are required to buy Thai company shares?

For private companies, buyers must sign a Share Purchase Agreement (SPA), complete a share transfer form, update the register, issue new certificates, and file with the Ministry of Commerce. For public companies, trades are made digitally under the Electronic Securities Bill, with instant registration and fees starting from THB 100.

What are the best platforms to buy shares in Thailand?

Investors can use SEC-licensed brokers, top Thai banks like Bangkok Bank or Kasikornbank, international brokers approved in Thailand, or SET-regulated digital platforms. Key selection factors include fees, multi-language support, ease of use, and platform reliability.

What risks come with digital trading of Thai shares?

Digital trading requires strict compliance with KYC, AML, and identity verification under the 2025 Electronic Securities Bill. Investors should only use SEC-approved platforms, avoid hidden-fee brokers, and be cautious of unsolicited offers. Compliance safeguards reduce fraud risk, but vigilance is still essential.

What risks should be checked before buying company shares in Thailand?

Key risks include unclear title transfer, hidden debts, shareholder disputes, regulatory non-compliance, and minority rights restrictions. Due diligence should confirm corporate registration, financial liabilities, governance structure, and compliance with Thai corporate laws.

What are the tax implications of buying Thai company shares?

Capital gains tax applies to share sales, with possible withholding tax on foreign transactions. Reporting obligations exist with the Thai Revenue Department. Double taxation treaties may reduce tax burdens, while BOI-promoted companies can qualify for exemptions or incentives.

Can foreigners buy Thai company shares from overseas?

Yes. In 2025, foreigners can buy Thai shares online through licensed brokers or banks using passport ID, proof of address, KYC form, and sometimes a tax ID. Electronic signatures and digital verification streamline the process for overseas investors.

What is the minimum investment required to buy Thai shares?

Private company shares have no set minimum beyond the par value (often THB 5–100 per share). Publicly listed shares can usually be bought in small lots, often starting at 100 shares, depending on the broker. This makes Thai shares accessible to both small and large investors.

What restrictions apply to selling Thai company shares?

Restrictions may include lock-up periods for insiders, usually 6–12 months, and mandatory disclosure requirements for large or controlling sales. All transfers must comply with SEC rules and be registered to remain valid.

How are disputes or fraud handled in Thai share transactions?

Disputes can be resolved through mediation, arbitration, or Thai courts. The Securities and Exchange Commission (SEC) also accepts complaints regarding listed companies. Investors should keep contracts, receipts, and evidence to support claims and ensure faster resolution.

Key control issues include:

Pre-emptive rights: existing shareholders may have the first right to buy new shares
Special resolutions: some decisions require higher shareholder approval thresholds
Registration: all share transfers must be registered with the Ministry of Commerce or SET, depending on the company type

Failure to register a share transfer can result in loss of legal ownership or regulatory penalties.
