Any income earned in Thailand is subject to Thai Income Tax. 

The Thailand Revenue Department (TRD) changed its rule for money transferred into Thailand beginning with calendar year 2024. 

As a result, Expat in Thailand MAY be subject to paying Thai Income Tax.

Each Person’s financial situation differs, so each Expat should evaluate their particular about filing a Thai Persona Income Tax Return and paying any tax liability.

The PCEC suggests the following approach:

Are you a Tax Resident?

First, determine the number of days you have resided in Thailand during the calendar year. This is cumulative days, not consecutive.

If you have resided in Thailand 180 days or less, you are not subject to Thai Personal Income Tax as you are not considered a Tax Resident.  Thus, no further action is needed as you will have no income tax liability.

If you have resided in Thailand more than 180 days, you are considered to be a Thai "Tax Resident" and may be subject to paying Thai Income Tax for monies remitted into Thailand during the calendar year 2024 and thereafter.

EXPAT TAX RESIDENT - REMITTING MONEY INTO THAILAND

Thailand Personal Income Tax

If you are a Tax Resident, then you are subject to paying Thailand's Personal Income Tax on money remitted into Thailand from overseas if it is

"assessable income." This Rule became effective for calendar years beginning 1 January 2024  and thereafter.  The Thai Personal Income TaxReturn for 2024 is to be filed with the Thai Revenue Department by March 31, 2025.  

Identify by source the  money you brought into Thailand

Your first step should be to determine the total amount of money brought into Thailand during calendar year 2024 (include bank transfers and withdrawal of funds using a foreign bank card in a Thai bank's ATM).

The amount(s) should be categorized by type, e.g. savings*, pension, wages, investments (interest/dividends), etc.

* Money held in saving as of December 31, 2024 and subsequently transferred into Thailand is still not taxable.  Previously TRD rules provided that only money brought into Thailand in the year it was earned to be taxable.

Determine if you have a Personal Income Tax liability

After identifying the source and amount of money  brought into Thailand, you will need to determine the total amount that is categorized as assessable income and any resulting Personal Income Tax liability.

Thailand's Revenue Code and Revenue Department Rules have provisions for subtracting deductions and allowances before calculating the amount, if any, of tax owed.  To determine if you may have a Thailand Personal Income Tax liability, follow the steps below for Calculating Your Tax Liability.

CALCULATING  YOUR TAX LIABILITY (if any)

Thailand has different requirements and allowance depending on the type of assessable income. NOTE: If the money is from savings from income received prior to January 1, 2024 it is not taxable in Thailand*.

Step 1 - Identify your money transferred into Thailand.

Step 2 - Remove any amounts that are not assessable income** based on its nature or if it is exempt under Thailand's Dual Tax Agreement with the source country (currently, Thailand has such Agreements with 61 other countries).

Step 3 - Subtract from assessable income your allowable deductions and allowances to arrive at taxable income.

Step 4 - Apply the appropriate tax rate which is progressive.

* Previously TRD considered only money brought into Thailand in the year it was earned to be taxable.

** The Revenue Code and Revenue Department Rules lists the type of funds that are considered income.
