I can't count the number of times that a client has come to me asking for help to find a payroll service key. It used to be that you had to find the right person in payroll customer service and they would be able to email it to you. Now Intuit has solved the problem with a self-service tool.

Just go to this knowledegebase article:

and click on the "Automated Service Key/Disk Delivery Key Tool" link. All you will need is your federal EIN number.
