The payroll item for 401K roth was set up as pretax and it needs to be post tax. Is it possible to change the payroll item taxability and if so where do i do that?

Thank you for reaching out in the Community, lucindap95!

We're unable to change the tax tracking setup of your 401k item. For this reason, I'm going to route you to our QBO Payroll Support. That way, they can use more tools to review your setup and make payroll corrections.

To contact our Support team:

1. Sign in to your QuickBooks Online company.
2. Go to Help (?).
3. Select Contact Us.
4. Enter your concern, then select Let's talk.
5. Choose a way to connect with us:
   • Start a chat with a support expert.
   • Get a callback from the next available expert.

Please note of the following Support schedules as well:

• QuickBooks Online Payroll - Core, Premium, M-F 6 AM to 6 PM PT
• QuickBooks Online Payroll Elite - any time, any day

I just want to add the QuickBooks has a built-in article that you can use as reference when setting up deductions. It contains information about them, like how they are reported on your forms. Please check out the screenshot below.

Feel free to go back to this thread if you have other questions in mind. Have a good one!
