Whenever an employee leaves, you must continue to keep
a record for the employee so that you can send them the appropriate government
forms and remit any payments to the government at the end of the fiscal
year.
Make the employee inactive,
so that you don't inadvertently continue to issue cheques to them. In
some cases, you will not want to make the employee inactive even though
you have filled in the Terminate box. For example, if a salesperson leaves
your company before all of the sales that they made have been processed,
you will want to keep that salesperson active so that you can issue the
commission cheque in the future.
