# Income Tax Calculator (2026)

Page: https://atabekmusavirlik.com/en/hesaplama-araclari/gelir-vergisi

Enter your annual tax base to see the tax under the 2026 income tax brackets and the effective rate.

**In short.** The 2026 income tax tariff starts at 15% and rises to 40%. Tax is not computed by applying a single rate to the whole base: each bracket is taxed at its own rate, with the first bracket at 15% up to TRY 190,000.00. The third bracket's upper limit differs between employment income and other income.

**How the calculation works**

1. **Determine the tax base** — Deductions and exemptions are subtracted from income to reach the taxable base.
2. **Split the base across brackets** — The base is divided according to the tariff thresholds, each slice remaining in its own bracket.
3. **Apply each bracket's rate** — The first slice is taxed at 15% and later slices at progressively higher rates. Entering a higher bracket does not increase the tax on lower slices.
4. **Sum the bracket amounts** — The amounts from each bracket are added to give the annual income tax; advance tax and withholdings paid during the year are then offset.

Income tax in Turkey is calculated on a progressive (bracketed) schedule: as the base rises, higher slices are taxed at higher rates. In 2026, for non-wage income the brackets are 15% (up to ₺190,000), 20% (up to ₺400,000), 27% (up to ₺1,000,000), 35% (up to ₺5,300,000) and 40% above that.

Crucially, entering a higher bracket does not tax all your income at that rate. Each bracket applies only to the slice within its range; the ratio of total tax to base — the "effective rate" — is shown separately in the tool. That is the best measure of your actual average tax burden.

This tool estimates non-wage income tax (business, rental, self-employment income, etc.) on an annual base. For wage income the third bracket threshold differs (₺1,500,000) and the minimum-wage exemption applies. Work with your accountant for the return, deductions and exemptions.

**Frequently asked questions**

- **Q: What are the 2026 income tax brackets?**
  A: For non-wage income in 2026: 15% up to ₺190,000, 20% up to ₺400,000, 27% up to ₺1,000,000, 35% up to ₺5,300,000, and 40% above.
- **Q: Does moving into a higher bracket tax all my income at that rate?**
  A: No. Each rate applies only to the slice within its range. For example, only the portion above ₺190,000 is taxed at the next rate; lower slices keep their own rates. The average burden is measured by the effective rate.
- **Q: What is the effective tax rate?**
  A: The effective rate is total income tax divided by the base. It is always lower than the top (marginal) bracket rate and reflects your true average tax burden.
