I appreciate all the efforts that you've exhausted just to get this working, lsundstrom.
I can share another set of troubleshooting steps that can help fix this issue.
After updating your tax table, you can revert the paycheck if you are still in the creation process or delete/void the paycheck if you haven't issued it yet. You'll also want to double-check that the deduction item has been added to the employee's profile. Here's how:
- Go to the Employees menu.
- Choose Employee Center, then open the profile of the appropriate employee.
- Head to the Payroll Info tab, then add the 401(K) deduction item in the Additions, Deductions, and Company Contributions section.
- Click OK, when you're done.
If the same thing happens, you can follow the steps in this article to further isolate the issue: Payroll items on paycheck are not calculating or are calculating incorrectly.
In addition, here's a reference that you can browse to help keep track of your payroll transactions in QuickBooks Desktop: Customize payroll and employee reports.
Drop me a comment below if you have other concerns or follow-up questions. I'd be more than happy to assist you again.
