Re: I got an email to update the withholding taxes table to 21908, I went to due to updated and it stayed at 21806 is there no changes for New Jersey?
Payroll updates are delivered to all no matter what states you have set up for payroll. Everybody gets all the updated files. If the payroll version stayed at 21806 then the payroll update didn't work.
Try restarting your computer to make sure everything QB related is unloaded from memory. Then get the update again from the Employees menu. If you receive no errors, then deal with them, otherwise it probably worked.
