Many people only discover near the end of the year that the insurance premiums they pay every month can be claimed against their Thai personal income tax. This article walks through the basics step by step, so you can start planning with a clear picture.

Why insurance premiums are deductible

The government encourages people to hold their own protection, so certain life and health insurance premiums may be deducted from assessable income before tax is calculated, under the criteria set out in law. The lower your net income, the less tax you pay according to the progressive tax bands.

The main allowances to know

  • Life insurance premiums — deductible as actually paid, up to THB 100,000, provided the policy term is 10 years or more.
  • Your own health insurance premiums — up to THB 25,000, and combined with life premiums must not exceed THB 100,000.
  • Your parents' health insurance premiums — up to THB 15,000, subject to conditions on your parents' income.
  • Pension insurance premiums — up to 15% of income and no more than THB 200,000.

These figures reflect the current criteria, which may change from one tax year to the next.

Start by knowing your own tax band

Before choosing a policy, work out which tax band your income falls into, because the tax you save depends on your highest marginal rate. Someone in the 20% band saves considerably more from a THB 100,000 deduction than someone in the 5% band claiming the same amount.

Choose a policy that fits your life, not just your tax bill

The deduction is a welcome by-product, but the heart of insurance is protection. Ask yourself who you need to look after, what obligations you carry, and how much premium you can sustain over the long term — then choose a policy that matches those answers.

  1. Gather your income for the year and the deductions you already have.
  2. Run a rough tax calculation to see how much deduction capacity is left.
  3. Set a premium budget you can sustain over the long term.
  4. Talk to an agent or adviser to compare policies before deciding.

Planning early leads to a more considered choice than rushing at the end of the year — and it means every baht of premium works on both fronts, protection and tax, at the same time.
