What is the Income Tax Calculator?

Income tax calculation is the process of determining the tax due on earned income. In Turkey, income tax is calculated by progressively taxing income earned within the year according to income tax brackets. Using the income tax calculation tool, you can enter income, expenses, and other deductions to quickly calculate the income tax payable.

How is Income Tax Calculated?

When calculating income tax, the tax base is first found by deducting expenses from the individual's earned income. Then, this amount is taxed according to the income tax brackets determined for the relevant year.

The income tax calculation process typically follows these steps:

  • Total annual income is calculated

  • Expenses are deducted to find the tax base

  • Income tax brackets are applied

  • Deductions and withholdings, if any, are subtracted

The income tax calculator performs these operations automatically to easily display the tax amount due.

What Information Is Required for Income Tax Calculation?

Certain basic information must be entered to calculate income tax accurately. The income tax calculator typically uses the following information:

  • Monthly or annual income amount

  • Expenses

  • Operating period

  • Tax incentives such as young entrepreneur discount

  • Withholding tax payments

Once this information is entered, the tool calculates the tax base and automatically calculates the income tax due.
