About this tool

Income tax assessed on the annual return is paid in two equal instalments in March and July (Income Tax Law art. 117). Tax withheld during the year and provisional tax paid are credited against it (arts. 120–121). This tool applies the selected tariff, deducts the credits and splits the balance.

How to use

  1. Enter the taxable base.
  2. Choose the tariff.
  3. Enter withholding and provisional tax paid, then press Calculate.

Notes

An odd kuruş is added to the first instalment; the second is the remainder.
