Napsa error on upload for return - EmployER number mismatch

If you see an error on the Napsa upload saying "EmployER number mismatch" This is normally an issue with a specific employee's SSN number (Social Security Number) that is issued by NAPSA to each employee registered with NAPSA. However this Number is linked with a specific EmployER number! Sometimes employees move from working for one company to another and if this has not been updated with NAPSA for the particular employee, then the file will fail to upload. Ask NAPSA to make sure the SSN number for the employee is linked with your NAPSA employER number. Also please make sure that you have registered your correct NAPSA employer number on the company settings page. The default is 33333 for all newly registered companies with Harvester Online and this needs to be edited to your employer number.
