If you have other questions or concerns, please let me know. I'll be around for you. Take care and have a great day ahead.

I have repeatedly done these things with the guidance of QB Experts.  We have made 'dummy' new HSA deductions and tested that, same issue.   I believe the issue is in the setup of the HS Pretax account AND in payroll checkup the deduction is added back to into the taxable wage.  Example:  Three columns:  Amount - zero, Wage $200, Income subject to tax $200.  This causes the pretax deduction to be added back into the gross wage and taxed.  If I adjust that 'payroll adjustment' created by payroll checkup to zero, the taxes are computed correctly.

We offer Simple IRA too. We have ours set up as a Payroll Item deduction. Simple IRA is pretax so it is off of Gross Wages. 

For Tax Tracking Account: We have Simple IRA. 

We also offer up to 3% company match which is set up as a Payroll Item Company Contribution.

I hope this helps some.

We offer a simple IRA and that has worked perfectly.  It is the HSA that continues to create issues.  It is pretax dollars from employee payrolls.   Only three participate, therefore there are only three that QB calculates the taxes incorrectly for both medicare and social security.  

I'm still looking for a solution.

I appreciate you for getting back on this thread, Cmdermott. It's rough when the HSA continues to create issues. I'm here to help you with that.

Payroll tax and wage calculations are derived from payroll data and transactions entered into QuickBooks Desktop. Your tax set up and payroll items should be set up correctly to ensure accurate tax calculations. For more tips in making sure the set up is correct, I'd suggest checking out these articles:

• How QuickBooks Calculates Payroll Taxes

You can follow these steps to verify how a payroll item is set to calculate in the program:

1. In the top menu bar, select Lists then Payroll Item List.
2. Right-click the deduction you want to verify and select Edit Payroll Item.
3. Click Next until the Gross vs. Net screen.
4. Verify the selection is correct.
5. Click Next until you can click Finish.
6. Click Finish.

For more details, please review the following sections in this article: Payroll Items on Paycheck aren't Calculating or are Calculating Incorrectly.

I'd also recommended running payroll reports on a regular basis to review your employee(s)' payroll data so you can catch mistakes before the tax filing season. You can use the Payroll Detail Review report to verify your employees' year-to-date (YTD) wage and tax calculations. 

Additionally, it's easy to view your employee data and track your business finances with QuickBooks. To do this, you can open any Excel-based payroll reports that suit your needs. 

You can always get back here and post a question if you need help resolving QuickBooks issues, Cmdermott. I'm always around to help. Have a good one. 

Sorry I wasn't any help. I hope you find the solution sooner rather than later.
