July 2023 tax table update

Need some assistance on this one. 

I have downloaded the latest tax table update - all good from that perspective. 

Manitoba has increased the provincial TD1 amount for 2023.   From $10855 to $15000.  The tax table is now showing a prorated amount for July 2023 payroll onwards to reflect this change.

If I have a new employee who has not been paid in 2023 yet, is the provincial TD1 $15000 or is it the prorated amount?  

If I have manually updated an employee's provincial TD1 prior to the July 2023 tax table do I manually update from the prorated amount or from the $15000? 

The QB support post (Download the Latest Payroll Tax Table) doesn't quite answer.  It suggests you need to update but it doesn't clarify from which amount (prorated or the $15000).  

Not sure how to handle this. 

Thanks in advance.
