The VAT calculation application is a tool that is used to quickly and precisely calculate the amount of VAT due on a given transaction. It can be used by entrepreneurs, accountants or individuals who want to track their expenses and settle accounts with the tax office.

The application consists of a simple interface where the user can choose whether he wants to calculate VAT from the net amount to the gross amount or vice versa. Depending on the selected option, he enters the net or gross amount and the VAT rate, respectively, and then receives the result in the form of a gross or net amount, respectively. The application can take into account different types of VAT rates (e.g. basic rate of 23%, reduced rate of 8%, etc.), which allows for precise calculation of the amount due on a given transaction.
