Summary
Enter your capital gain, asset type, and annual income to estimate Thai personal income tax on investment gains under the 0–35% progressive brackets.
How it works
- Enter the capital gain — the profit from selling the asset (sale price minus acquisition cost).
- Select the asset type: SET-listed shares sold through the exchange (exempt for individuals), or other assets such as property, foreign shares, or crypto.
- Enter your other taxable income for the year (salary, business income, rental, etc.) before this gain.
- The calculator adds the taxable gain to your other income and computes PIT using Thailand's progressive brackets.
- Tax already attributable to your other income is subtracted so only the marginal tax on the gain is shown.
- Results include total PIT on the gain, the effective rate on the full gain, and net gain after tax.
