Personal Income Tax Thailand

Personal Income Tax is applicable to an individual whose income came from employment or from a property located within the country but the income from it was either paid with in Thailand or at a foreign soil. The Personal Income Tax is considered as a principal tax and classified as a direct tax.

There are two classifications of taxpayers: Resident and Nonresident. A resident taxpayer is someone who has resided in Thailand for a period that totals more than 180 days. Both incomes earned domestically or in foreign soil are subject to taxation. For Non-resident, only incomes earned in Thailand are subject to taxation. An individual taxpayer must file his tax return for each calendar year on or before the 31st of March of the following year.

In case a foreign employee was not able to pay his income tax on or before the deadline, the employer would normally be the one who would pay for him. Yet, a different schedule applies for incomes derived from property selling or the profession of such individual is either of the following: engineering, architecture, accountancy, fine arts and art of healing. The individual must also file his mid-year tax return on or before the 31st of September and consequently pay the tax due on or before the 30th of June the following year. Note that when you renew your work permit they will need a copy of your tax submissions for the year before. Tax submission are normally done in February each year.

The application of the personal tax is done in graduated schedule starting from 10% to 37% and is subject to deductions.

In 2008, the Government of Thailand also introduced THB 150,000 exemption cap on taxation of personal income. This means to say, individuals whose income fall below THB 150,000 are not subject to personal income tax.

    For a taxpaying individual, either a Thai national or a foreigner, the taxation system of the Kingdom may be very confusing. Added with the tax rates and terminologies, understanding one’s tax obligations may even get more perplexing.

    Therefore, soliciting services from Thailand based accountants can be very helpful. Their services surely requires you to spend a few more baht but the security they will provide you from tax related lapses will eventually prove priceless.
