Thailand capital gains tax calculator

Thailand has no separate capital gains tax. SET-listed shares and mutual-fund units are exempt for an individual. Unlisted shares, other assets and taxable crypto are ordinary income that stacks on your other income at the progressive rates: 0% to 150,000 baht, then 5%, 10%, 15%, 20%, 25%, 30% and 35% above 4,000,000 baht. Property uses the Section 48(4) computation.

Yes for an individual investor selling through the exchange. The exemption does not cover debentures or bonds, and a juristic investor pays corporate income tax instead. The Revenue Code Section 42 list does not carry the subsection, so the exemption rests on subordinate legislation.

Digital-asset gains are ordinary income with a 15% withholding under Section 50(2)(f) where both parties know the price, creditable against your personal income tax. Gains made through SEC-licensed exchanges, brokers and dealers are exempt from personal income tax from 1 January 2025 to 31 December 2029.

For property not acquired in a commercial or profitable manner, Section 48(4) deducts expenses at the Royal Decree No. 165 rate (92% in the first year, falling to 50% from the eighth), divides the net income by the holding years, taxes it at the progressive rates and multiplies back by the years. A holding period over 10 years counts as 10, and a fraction of a year counts as one.

Thailand taxes an individual's gains as ordinary income rather than under a separate capital gains tax. Gains from transferring shares or partnership holdings fall in assessable income category 4 of Section 40; immovable property is taxed under the Section 48(4) computation; digital-asset gains are ordinary income with 15% withholding under Section 50(2)(f). Shares listed on the Stock Exchange of Thailand are exempt for an individual investor, as are mutual-fund units under Section 42(23). Capital losses are not modelled: PwC states capital losses may not be offset against capital gains and no Revenue Department or Revenue Code provision permitting private-investor loss netting or carry-forward was found (NOT SOURCED), so the calculator reports losses without deducting them.

SET-listed shares: a resident individual does not pay personal income tax on the gain from selling shares listed on the Stock Exchange of Thailand. The exchange's investor tax page states, for capital gains on direct investment in SET/TFEX, 'Individual Investor — Tax exempt', and adds that the exemption does not cover debentures and bonds and applies to the individual rather than a juristic investor. The Revenue Code Section 42 exemption list on the Revenue Department's English site contains no subsection for SET share sales, so the exemption comes from subordinate legislation: one secondary source names Ministerial Regulation No. 187 (B.E. 2534) and another describes 'a long-standing Royal Decree'; the instrument type and number are unresolved (NOT SOURCED, flagged).

Mutual fund and ETF units: 'Section 42(23) Income from sale of investment units in a mutual fund' is exempt from personal income tax under the Revenue Code itself. A Thai ETF structured as a mutual fund takes the same treatment; no separate ETF statute was found, and a foreign-domiciled ETF is not covered and falls to the general rules. Mutual-fund distribution income carries 10% withholding or is included in the year-end return. Sources: https://www.rd.go.th/english/37749.html and https://www.set.or.th/en/market/information/tax

Unlisted shares and stakes: there is no exemption. Gains from transferring shares or partnership holdings are assessable income under Section 40 category 4 and are taxed at the progressive personal income tax rates in the th-income-tax records, up to 35%. A resident individual seller self-assesses the gain in the annual return; the buyer is not typically required to withhold. A share transfer instrument also attracts stamp duty at 0.1% of the paid-up value or the consideration, whichever is higher, and there is no VAT or SBT on a share transfer.

Digital assets: profits or benefits from holding or possessing digital tokens, or gains from transferring cryptocurrency or digital tokens, are ordinary income and are subject to withholding at a flat 15% under Section 50(2)(f) of the Revenue Code; the income is also included in assessable income at the progressive rates, the 15% withheld being creditable. The withholding applies to transactions in which both the buyer and the seller know the transaction price; when a trade is carried out on a licensed exchange and the parties do not know the counterparty's pricing, there is no withholding obligation. The Cabinet approved on 17 June 2025 a personal income tax exemption for gains derived from the sale of digital assets through licensed digital-asset business operators (exchanges, brokers and dealers licensed under the Emergency Decree on Digital Asset Businesses 2018), running from 1 January 2025 to 31 December 2029; the enabling Ministerial Regulation under the Revenue Code was still a draft at capture (NOT SOURCED).

Immovable property is ordinary income, not a separate capital gains tax. The assessable price is set from the Land Department appraised value (Revenue Code Section 49 bis). Where the property was not acquired in a commercial or profitable manner, tax may be computed under Section 48(4): expenses are deducted at the rate prescribed by Royal Decree No. 165 B.E. 2529 — 92% for one year of holding, 84% for two, 77% for three, 71% for four, 64% for five, 60% for six, 55% for seven and 50% for eight years or more — and the net income is divided by the number of years of holding, taxed at the progressive rates and multiplied back by the years. A period exceeding 10 years counts as 10, and a fraction of a year counts as 1. Sources: https://www.rd.go.th/fileadmin/user_upload/kormor/eng/RD_165.pdf and https://www.rd.go.th/english/37749.html

Specific business tax and transfer costs: 3% SBT plus a 10% local levy on the tax, 3.3% of the assessable value, applies to the sale of immovable property in a commercial or profitable manner and to the sale of securities in a securities market (exempted). A natural person is exempt from SBT where the property has been owned for more than five years, or where the seller's name has been entered in the house register for the property for at least 12 months; the two conditions are alternatives. The transfer registration fee is 2% of the Land Department's appraised value, ordinarily shared equally, reduced to 0.01% for qualifying residential property by the Cabinet measure of 30 June 2026, which runs to 30 June 2027 and caps the price and appraised value at 7,000,000 baht. Where SBT applies, stamp duty is exempt. Sources: https://www.rd.go.th/english/6042.html and https://www.nationthailand.com/business/property/40068066

Other assets: movable property acquired by inheritance or acquired not in a commercial or profitable manner is exempt under Section 42(9), which carves out ships and floating houses. A sale made in a commercial or profitable manner is not exempt and is taxed as ordinary income. No separate rate, threshold or holding-period rule for art, collectibles, gold, jewellery or vehicles was sourced. Source: https://www.rd.go.th/english/37749.html
