Calculating Retirement on non payroll items

Welcome to the Community, @Alexuus.

Let me help and provide information about Retirement Contributions in QuickBooks Online Payroll (QBOP).

To begin with, QuickBooks Online (QBO) does not have a specific sequence for calculating payroll items. Any payroll item added to the program will be automatically calculated and included in the total. As a workaround, to prevent stipends from affecting retirement contributions, you have to create a separate paycheck for payroll items.

For now, I recommend sending feedback. Your feedback will help us improve your QBO experience and will be shared with our Product Development Team.

Here's how:

1. At the upper right corner, click the Gear icon.
2. Under the Profile, select Feedback.
3. Enter your comments or product suggestions.
4. Then, select Next to submit a feedback.

For more details about the feedback process, you can check this article: Submit Feedback.

You can also check this to track your request: Customer Feedback for QuickBooks Online.

For future reference, you can check this article to guide you in running payroll reports: Run payroll reports.

Please feel free to drop a comment below, if you have further concerns about the Retirement contribution or other QBO-related concerns. I will answer them in any possible way.
