Additional Federal Withholding issues

Hi there, @WTC,

I want to ensure your employees payroll taxes in QuickBooks Desktop calculates correctly.

The Additional Federal Withholding should not affect any other tax calculations on the paycheck. See this:

There are a few reasons why there are unexpected behaviors when working with QuickBooks Payroll. Consider the following:

• QuickBooks is not updated, or an internet interruption occurred during the update.
• Using an incorrect tax table version.

To correct this, let's make sure you're able to download the latest tax table update version 22004. You can check that by following these steps:

1. Go to the Employees tab, and select Get Payroll Updates.
2. You'll see the tax table version beside the Payroll Update Info button. (Please see screenshot.)
   
3. If it's not showing the correct version, click the Download entire payroll update radio button then press Update.

Next, review the status of the Payroll if it is showing active in the company file. Here's how:

1. Go to the Employees tab and select My Payroll Service.
2. Pick Manage Service Key from the list.
   
3. In the Status column, verify if it says Active.
4. You can also view your subscription status by pressing Ctrl + K on your keyboard.
5. If the status says Active, click the Edit button.
   
6. Click Next.
7. Uncheck the Open Payroll Setup - I want to start right tick box.
8. Click Finish.

Once done, redo your payroll processing and see if the same issue happens again. Let me know the result in the comment section below. I'll be more than glad to share additional insights and assistance whenever you need one. All the best!
