Income Tax is a tax levied by several countries, where each individual or company is required to deduct a percentage of their average annual income to the Government. This percentage can vary according to the average annual income, or it can be fixed at a percentage.

In Brazil, Income Tax is charged (or paid) every month on the Payroll (there are some cases where the monthly fee is optional by the taxpayer) and in the following year the taxpayer prepares an annual adjustment statement of how much it owes from the IRPF (or has refund of amounts paid in excess), and these amounts must be approved by the tax authorities.
