Thailand Tax Calculator for Remote Workers

Thailand has 8 progressive brackets on net taxable income (after deductions): 0% on the first ฿150,000, 5% to ฿300,000, 10% to ฿500,000, 15% to ฿750,000, 20% to ฿1,000,000, 25% to ฿2,000,000, 30% to ฿5,000,000, and 35% above. These rates have been stable since 2017.

Employees receive an employment expense deduction of 50% of income (capped at ฿100,000) plus a personal allowance of ฿60,000. Combined with the 0% bracket on the first ฿150,000 of net income, a single employee effectively pays no tax on roughly the first ฿310,000 (~$9,000) of income.

Freelancers with Section 40(8) business income can claim a 60% flat-rate expense deduction (or actual expenses if higher). After deducting the ฿60,000 personal allowance, the same 8-bracket PIT rates apply. Payers withhold 3% on service fees, which is credited against the annual tax — not an extra cost.

Employees contribute 5% of monthly salary, capped at ฿15,000/month (max ฿750/month or ฿9,000/year). The employer matches this. Self-employed can voluntarily join Section 40 at ฿100-300/month for basic benefits, but it is not mandatory.

Unlike most countries, Thai contractors can take home more because the 60% flat-rate expense deduction is very generous — it reduces taxable income far more than the employee's 50%-capped-at-฿100,000 deduction. However, contractors miss out on employer-matched social security, health benefits, and employment protections.
