Frequently asked questions
How much income tax do I pay if I work in Thailand?
Thailand has a progressive income tax system with 8 brackets ranging from 0% to 35%. The first 150,000 THB of your taxable income is tax-free, then rates increase from 5% on income between 150,000 to 300,000 THB up to 35% on income above 5,000,000 THB. However, you'll benefit from a 50% employment expense deduction (capped at 100,000 THB) and a 60,000 THB personal allowance that reduce your taxable income before tax is calculated.
What is the social security contribution in Thailand and can I deduct it?
As an employee in Thailand, you must contribute 5% of your gross income to the Social Security Fund, with a maximum annual contribution of 9,000 THB (approximately 750 THB per month). This contribution is deductible from your taxable income, which means it reduces the amount of income subject to personal income tax.
What deductions can I claim on my Thailand tax return?
The model assumes a standard employment expense deduction of 50% of your employment income (capped at 100,000 THB) and a personal allowance of 60,000 THB for single taxpayers. While additional deductions like charitable donations, life insurance, health insurance, mortgage interest, and retirement fund contributions are available, they are not included in this baseline calculation and would require itemization on your actual tax return.
Will my tax situation be different if I'm not a Thai resident?
Yes, this calculator assumes you are a resident employee with employment income only. Non-residents have different taxation rules and may be subject to different treatment of foreign income and remittance rules, so you should consult with a local tax professional if you don't have Thai residency status.
How much will I take home after taxes and social security?
Your take-home pay depends on your gross salary and the deductions applied. After subtracting the 5% social security contribution, the 50% employment expense deduction (up to 100,000 THB), and the 60,000 THB personal allowance, your remaining income is taxed at the progressive rates. Use the calculator above to enter your salary and see your exact take-home amount.
