There used to be a "No Tax Period" feature in SPS. Where is this in Indigo?

This feature was used in SPS, and it has been replaced by the Tax Credit feature in Indigo Payroll.

Go to "Employees" from the Payroll tab.

Double-Click on the employee for which you would like to use this function. Go to the "Tax" tab on the employee.

Create a new Tax Credit entry by clicking on the "Insert" button.

Enter Credit Amount, Start Date and End Date as necessary.  Click "Save" to save your changes.
