Yes, Regina. You can set up a Roth Solo 401(k) as a deduction item within your employee settings or by creating an account in the Chart of Accounts as a workaround.
While QuickBooks Online Payroll doesn't have a dedicated option for a Roth Solo 401(k), you can still set this up as a deduction item to ensure it appears on your payroll forms.
Before following the steps below, I recommend consulting your accountant to ensure proper recording.
Here's how to create a retirement plan deduction item:
- Head to the Payroll menu, then click Employees.
- Select your preferred worker.
- Click Start or Edit in the Deductions & Contributions section.
- Select the + Add deduction/contribution option.
- Choose Retirement Plans for the Deduction/contribution type and 401(k) for the Type.
- Input the necessary details, including the Employee deduction and Company contribution.
- Hit Save, then repeat the same process for your other employees.

Another workaround is to add Roth Solo 401(k) as an account in the Chart of Accounts. If you choose this process, it's best to consult your account for guidance in selecting the suitable category.
