I have already finalised all employees, However, when my employees check their myGov accounts, it still shows their income statements as “Not Tax Ready.

We can check if the finalisation declaration was correctly added and successfully processed, maybemay5211. 

You'll want to check the status of the finalisation event submitted in QuickBooks Online Payroll. Here's how:

1. Go to the Payroll tab.
2. Click on Reports and choose Single Touch Payroll.
3. Select the Financial year and pay schedule.
4. Verify if all employees are set to 'final' and their status is successful.

Once successful, and still showing Not Tax Ready on the ATO site. Let's create an updated pay event and tick the employee to be final. 

1. Click on the Payroll tab.
2. Click on the Reports tab.
3. Click on Single Touch Payroll.
4. Click on Create update event.
5. Select the appropriate Financial year and Pay schedule, then select Create.

If processed, and you changed your payroll software or updated the payroll IDs for the employee during the year, check if you duplicated their data in your payroll software. Otherwise, if you have access to those records, correct the duplication and submit the finalisation declaration.

On the other hand, you can reach out to the ATO Support Team. They can assist you further to verify the duplicated data.
