INDIVIDUAL TAXATION

Nonresidents are liable to tax on income derived from Thai sources. Married couples may opt to have joint tax liability; although the wife needs to file a separate tax return on her employment income, the couple´s combined taxable income will essentially be credited to the husband´s.

Personal income tax returns must be filed on or before 21 March in respect of taxable income received during the preceding calendar year.

RENTAL INCOME
The taxable income is determined after deducting expenses incurred from gross income. A standard deduction of 10% to 30% is permitted for rental income depending on the type of property leased.

The standard deductions for rental income vary according to the rental income classification:

• income from buildings and wharves - 30% of income
• income from agricultural land - 20% of income
• income from all types of land - 15% of income
• income from vehicles - 30% of income
• income from other types of properties - 10% of income

If houses, buildings, and floating houses are rented out by the owner, 30% of the gross rent can be deducted for expenses. The actual expenses incurred can be deducted, especially if it is higher than the standard deduction stated above, but it must be supported by documents.

Rental income is subject to a 5% withholding tax.This tax is then credited to the final tax liability of the taxpayer, when he files an income tax return.

CAPITAL GAINS

Capital gains derived from the sale of immovable property are taxed at the standard income tax rates.
