Thailand Tax Rates 2026: Personal Income Tax, Corporate Tax, VAT and Withholding Tax

Thailand Personal Income Tax Rates - 2026

Thailand uses progressive personal income-tax rates. The first THB 150,000 of net taxable income is exempt, after which rates rise progressively to 35%.

An individual is generally treated as a Thai tax resident when present in Thailand for at least 180 days in a calendar year. The tax treatment of foreign-source income depends on residence, source, timing and remittance rules, so such income should be considered separately rather than applying a single flat rate.

Personal Income Tax for Non-Residents

There is no universal 15% tax rate for all non-resident personal income. A non-resident is generally taxable on Thailand-source income, but the applicable rate and withholding mechanism depend on the category of income. Certain payments to non-residents, including specified income under the Revenue Code, may be subject to 15% withholding, while dividends are generally subject to 10% withholding. An applicable double tax agreement may reduce domestic withholding.

Separate Taxation of Interest and Dividends

Certain investment income may be subject to final or creditable withholding arrangements. Interest paid to an individual is commonly subject to 15% withholding in specified cases. Dividends paid by Thai companies are generally subject to 10% withholding, subject to the taxpayer's status, available tax-credit rules and any applicable exemption.

Thailand Withholding Tax Rates

Withholding tax depends on the type of payment and the status of the recipient. The following table summarises commonly encountered domestic withholding rates; special rules and treaty reductions may apply.

Corporate Income Tax Rates in Thailand

The standard corporate income tax rate is 20% of net profit.

Qualifying small and medium-sized companies may benefit from reduced rates. Under the Revenue Department's published schedule for qualifying companies meeting the statutory paid-up capital and revenue conditions, net profit up to THB 300,000 is exempt, the portion above THB 300,000 up to THB 3 million is taxed at 15%, and the portion above THB 3 million is taxed at 20%.

Different bases and rates can apply to particular entities, foreign companies, foundations, associations and specially promoted activities.

Capital Gains Tax in Thailand

Thailand does not impose a separate general capital gains tax. Gains that are taxable are generally dealt with under personal or corporate income-tax rules.

For an individual, gains from the sale of shares on the Stock Exchange of Thailand are generally exempt from personal income tax under the relevant ministerial regulation. Other securities, private-company shares, property disposals and cross-border investment gains may have different income-tax and withholding consequences.

Value Added Tax (VAT) in Thailand

The statutory VAT rate in the Revenue Code is 10%, but it has been reduced by Royal Decree. The Revenue Department has confirmed that the reduced 7% VAT rate continues through 30 September 2027.

The 7% rate generally applies to taxable supplies of goods, services and imports unless a zero rate or exemption applies. Exports and certain qualifying international services may be zero-rated under the Revenue Code.

Thailand Tax Return Filing and Payment Deadlines

The Thai tax year for individuals is the calendar year. A personal income-tax return is generally due by the last day of March following the tax year. Individuals with specified categories of income may also have a half-year filing obligation, generally due by the last day of September.

Corporate income-tax filing and instalment requirements depend on the accounting period and the relevant return. Withholding-tax, VAT and other recurring filings have separate monthly deadlines, including different rules where electronic filing extensions apply.
