You can reinstate (or reactivate) an ex-employee by reusing their employee record. All you need to do is remove the Termination date from their record and ensure their payroll details are up to date.
Alternatively, you can set up a new employee record for the returning employee. You can't have two employee records with the same name, so you'll need to update the name in the old employee record. Maybe add "old" or similar to the end of the employee's name in their old employee record. You can then use the employee's name in their new record. You can also send the employee a self-onboarding request to speed things up.
If you're reinstating an employee in the same payroll year they were terminated and you're re-using their employee record, you'll need to undo their finalisation for Single Touch Payroll reporting.
To reinstate an employee
Go to the Payroll menu and choose Employees.
Select the option Show inactive employees.
Click the employee to open their record.
On the Contact details tab, ensure the employee's details are current and the Inactive employee option is deselected.

Click through each of the tabs in the employee's record and ensure their details are up to date.
