What is Corporate Tax Calculator?

Corporate tax calculation is the process of calculating the tax to be paid on the net corporate income earned by companies within an accounting period. Corporations, such as joint-stock and limited companies, are subject to corporate tax over the tax base generated in the relevant period. Thanks to the corporate tax calculator, the tax base, calculated tax, and net profit after tax can be quickly viewed.

How to Calculate Corporate Tax?

When calculating corporate tax, first the company's tax base for the relevant period is determined. Then, the tax payable is calculated by applying the current corporate tax rate to this amount. The Revenue Administration's e-Declaration announcement also states that the corporate temporary tax rate has been increased to 25%; in practice, this rate is also frequently used in annual corporate tax calculations on calculation screens.

The corporate tax calculation formula basically works with the following logic:

Calculated Corporate Tax = Tax Base × Corporate Tax Rate

At the end of this calculation, the company's tax burden and net profit remaining after tax can be easily viewed.

What Data is Used to Calculate Corporate Income Tax?

To calculate corporate tax accurately, the tax base must first be correctly determined. In such tools, the calculation is generally based on the tax period, the tax base, and the applicable corporate tax rate. Once the tax base is determined, the tool automatically displays the calculated corporate tax and the net profit after tax.
