It's not the experience we want you to have, Richard. Let me share some details about switching to payroll core and how you can get a copy of your data.
 
We want to inform you that you can access any historical data from Standard Payroll in QuickBooks Core Payroll through a downloadable zip file. It includes P32 documents, P11, P45, P60, and payslips.
 
We apologize for any inconvenience caused by the change. If you have any questions or need assistance, please let us know!

So we have to add 2 reports (Standard for months 1-7 + Core for months 8-12) together ourselves?

Having an archived zip file for our records and audit trail is fine for previous years. But all current tax year data from Standard should have been imported into Core so everything works seamlessly in the new system.

I'm also frustrated by this.

All data separated, not a fluid process at all.

Yes - anyone who has changed payroll systems in the past knows you only do this on 6 April at the start of a new tax year, unless there are very exceptional cicrcumstances. because it often causes total chaos like this!

I'm having the same problem.  I was told that the change over mid financial year would not cause any problems, but now I only get data showing on reports that has been entered since the change over to Core.

How do I get earlier reports/info?  Very frustrating :\ 

You have to go to the main Payroll > Overview screen and select the option to 'download payroll data'. Then fish the historic P11 reports out of the zip file. Then add them to the recent data from QB.

Very time consuming and really poor service from Intuit to mess this up so badly.
