Hello, Roxanne1946.
I understand the importance of sending T4 slips to your employees seamlessly. Let's go through some troubleshooting steps to resolve this and ensure the process runs smoothly.
First, did you encounter any error messages upon trying to email your employees' T4s? Providing this information will help us pinpoint the issue and offer an accurate solution.
In the meantime, ensure your employees have accepted your invitation to access QuickBooks Workforce. Here's how to verify:
- Navigate to the My Apps menu.
- Select the Payroll tab, then click on Employees.

- Choose the employee and go to Permissions.

- Confirm that their Access Status indicates Has Access.
Once confirmed, and you're still unable to email the T4 slips, you can log in to your account using a private or incognito browser window. This can help prevent issues caused by cached data or browser glitches that may interfere with functionality.
Alternatively, switch to a different supported browser for better compatibility.
If you need additional assistance, feel free to share more details.
