Per our 401K plan, fringe benefits such as S-Corp Owners Health Insurance and Personal Use of Company Car should be included when calculating deferral. Possible in QBs?

Hi there, Aritchart.

Thank you for reaching out with your question. I understand that you need to include fringe benefits, such as S-Corp Owners Health Insurance and Personal Use of a Company Car, in the calculation of 401K deferrals in QuickBooks Online (QBO).

Currently, QBO’s standard payroll features allow 401K deductions to be calculated as a percentage of gross pay, a flat amount, or per hour worked. Unfortunately, there is no direct option to combine Gross Pay and Other Pay (which includes fringe benefits) within the native 401K deferral calculation.

1. To add a deduction to your payroll, please refer to these steps:
2. On the left panel of your QBO account, click Payroll.
3. Select Employees, and choose an employee you want to add a deduction.
4. Go to the Deductions/Contributions section, then click Edit.
5. Click Add deduction/contribution.
6. Click the dropdown button under the Deduction/contribution type. Then, click Retirement plans.
7. Select After-tax Roth 401 (k).
8. Enter the necessary details.
9. Once done, click Save.

Also, I'd recommend reaching out to your accountant or any tax advisor to ensure an accurate selection of specific payroll tax mapping.
