Hello there, qcketamine.

I can see that updating employee's tax withholding is indeed essential to ensure accurate tax calculation. Hence, I'll share some troubleshooting steps to overcome the error you received so you can achieve your goal.

This message, Network error: Response not successful: Received status code 400, usually refers to the inability to process a request due to an issue perceived by the server. You can resolve it by troubleshooting your browser, which can be full of frequently accessed pages that cause this unusual behavior.

Let's begin by utilizing a private window through these keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

If it's successful, clear the cache from your regular browser to refresh the website's preference. You can also consider using the system's supported browser for the best and most secure experience.

On the other hand, you can refer to this material once you're ready to pay your employees through direct deposit or paper paychecks: Create and run your payroll.
