- Sole proprietors and ordinary partnerships pay taxes at rates of 10 to 35 percent on their net profits
- Limited partnerships, registered ordinary partnerships and limited companies pay corporate income tax at the general rate of 23 percent of their net profits for accounting periods commencing in 2012, reducing to 20 percent for accounting periods commencing in 2013

Note: living in Thailand does not necessarily exempt a person from filing tax returns and paying taxes in their home country. Although a person may be exempt from paying taxes if they earn less than their government's tax thresholds, filing a return helps to avoid any problems in the future. The relevant Embassy will have the appropriate forms and regulations for its country's taxes.
Taxpayers are classified into resident and non-resident. Resident means a person who resides in Thailand for a period or periods aggregating 180 days or more in any tax (i.e., the calendar) year.
Any taxpayer, whether or not Thai tax-resident, is liable to pay tax on income from sources in Thailand on a cash basis, regardless of where the money is actually paid.
A Thai tax-resident may also be subject to tax on income from sources overseas, if that income is brought into Thailand. In contrast, a tax non-resident will not be subject to tax on income sourced from overseas.
Income liable to personal income tax is called “assessable income”. The term covers income both in cash and in kind. Therefore, any benefits provided by an employer or other persons, such as a rent-free house or the amount of tax paid by the employer on behalf of the employee, is also treated as assessable income of the employee for income tax purposes.
Assessable income is divided into eight categories as follows:
- Income from employment with an employer
- Income by virtue of positions or services rendered
- Income from goodwill, copyright, franchise, other rights, annuity or income in the nature of annual payments derived from a will or any other juristic Act or judgement of the Court;
- Income in the nature of dividends, interest on deposits with banks in Thailand, shares of profits or other benefits from a juristic company, juristic partnership, or mutual fund, interest on loans or debt instruments, payments received as a result of the reduction of capital, a bonus, an increased capital holdings, gains from amalgamation, acquisition or dissolution of juristic companies or partnerships, and gains from transferring of shares or partnership holdings
- Income from letting out of property on hire and from breaches of installment sale or hire-purchase agreements
- Income from the liberal professions
- Income from construction and other contracts of work
- Income from business, commerce, agriculture, industry, transport or any other activity not specified earlier.
Taxpayers should make their deductions from the assessable income first before the allowances can be permitted. The calculation for taxable income is as follows:
- Assessable Income, minus deductions, minus allowances equals Taxable Income
The types of deductions for personal income include:
- Income from employment: 40 percent, not exceeding THB 60,000
- Income from royalties: 40 percent, not exceeding THB 60,000
- Income from property on hire
- Buildings/wharves: 30 percent
- Agricultural land: 20 percent
- Other types of land: 15 percent
- Vehicles: 30 percent
- Other property: 10 percent
- Income from liberal professions: 30 percent; medical profession - 60 percent
- Income from contract work: 70 percent or actual expenses
- Income from businesses: 40 percent to 85 percent depending on source of income or actual expenses
Allowances or exemptions for individual taxpayers include:
- Personal allowance
- Individual taxpayer: THB 30,000
- Married taxpayer: THB 30,000 for taxpayer's non working spouse
- Child allowance (for children under 25 and studying at an educational institution or declared incompetent): THB 15,000 each or 17,000 for each child studying in Thailand, to a maximum of three children

Tax credit for dividends
The withholding tax for an individual taxpayer on dividends or a share of profits is 10%. An individual who has domicile or is residing in Thailand and receives dividends from any company organized under the laws of Thailand (whether a listed, public or private company) is subject to personal income tax withheld at source at 10%, and also is entitled to claim a tax credit on the dividend depending on the corporate tax rate on the net profit of that Thai company from which that dividend is paid.
|Income||Taxable Income||Tax Rate||Tax Payable (Baht)||Cumulative Tax (Baht)|
|0 – 150,000||Nil||Nil||Nil||Nil|
|2,000,001 – 4,000,000||2,000,000||30%||600,000||965,000|
|4,000,001 or more||Variable||35%||Variable||Variable|

An individual can file their own tax return, but all returns must be filed in Thai. A company can file its own tax return but this must include the balance sheet which must be drafted by an accountant and be in Thai.
Every taxpayer, resident and non-resident, in Thailand must have a Thai Tax Identification Number (TIN) issued by the Revenue Department. This must be applied for within sixty days of receiving assessable income. If the person uses a personal identification number (PIN) issued in accordance with civilian registration law, a TIN is not needed.

To apply for a new TIN at any area revenue office, provide a photocopy of:
- House Registration Document, if applicable
- Court order appointing estate administrator, if applicable
The tax calendar for Thailand begins 1 January and ends 31 December. All taxpayers must file their taxes no later than 31 March for the previous tax year; for example, to file taxes from 2014, the deadline is March 31 2015. Payment must be made in full on or before the 31 March deadline. There is no payment plan at this time.
If income is derived from property on hire, liberal professions, contract work or business and income was received during the first six months of the year, the taxpayer must file a half-yearly return (Form PIT 94). The deadline for filing and payment is 30 September of that taxable year. Any half-yearly tax paid will be credited against tax liability on 31 December.
