Based on the legislation of various countries, there are **several IRS (the Portuguese personal income tax) regimes** (for example, the Tax Incentive Scheme for Scientific Research and Innovation (IFICI), tips, etc.) that, normally, consist of **applying a specific fixed IRS rate**.

So the product can adapt to the needs of each company, the application lets you **set up several IRS deductions.**

To configure multiple IRS regimes, you must follow this procedure:

1. In the **Deductions** table, create the IRS deduction with settings identical to an existing IRS deduction (D02 or D03), and you can specify the fixed rate to apply to that deduction.
2. In the **Administrator**, under **Parameters of the Financial Year | Deductions**, choose the **Other IRS Deductions** tab and enter the new IRS deduction.

**Note**: for these deductions to be handled correctly, you must make sure they are specified as **Other IRS Deductions** before processing is performed.
3. In the **Employee File**, enter the deduction in the **Other Postings** area.
4. In the configuration of the **Earnings Items or Overtime** that contribute to the deduction's taxable amount, enter the IRS deduction.

When processing Earnings Items/Overtime that **have the IRS deduction associated with them**, the system will calculate and perform the specific handling of IRS deductions, applying the rate or amount set in the deduction or in the file's other postings.

The Earnings Item/Overtime may come from the employee's record or from the monthly changes.

These IRS deductions behave the same way in the official reports as the other IRS deductions.
