Since you've confirmed the email address is correct, the next step is to have your employer contact QuickBooks Payroll support for assistance. This will allow the support agents to troubleshoot and fix any issues on the backend that are causing the login error.

Here's an article with their contact info: Contact Payroll Support.

As they investigate the specific error, here is an article that explains taxes on paychecks just in case you might need it: Understand the Income Tax on Your Paycheck.

Let me know if you have other questions about using Workforce. I'm always happy to help further or provide guidance on using the website.
