BANGKOK, Thailand – The government is urging all income earners to file their personal income tax returns for the 2025 tax year by the required deadlines, warning that failure to do so may result in financial and criminal penalties.
According to Deputy Government Spokesperson Airin Phanrit, tax returns can be submitted through the Revenue Department’s e-Filing system or the D-MyTax digital platform until April 8, 2026. Paper filings are accepted until March 31, 2026. Taxpayers with a tax payable of 3,000 baht or more may request payment in three installments under the Revenue Department’s rules.
Airin said late filers must pay the outstanding tax, along with a 1.5 percent monthly surcharge and additional fines. Intentional tax evasion may result in imprisonment of up to one year, a fine of up to 200,000 baht, or both. Providing false information carries heavier penalties, including prison terms of 3 months to 7 years and fines of up to 200,000 baht.
She added that paying taxes is a legal duty that supports national development, public services, and assistance for disadvantaged groups. All salaried workers and income earners are required to declare their income, and failure to do so may lead to both civil and criminal action. Additional information is available at Revenue Department offices nationwide or through the Revenue Department Intelligence Center at 1161.
The public has also been cautioned about scammers posing as the Revenue Department through fraudulent emails or messages offering fake tax benefits. Authorities urge people not to click on suspicious links or share personal or financial information. (NNT)
