Hello Aefs1,
Thank you for posting here in the Community. I'm here to assist you with any questions you may have with your subscription in QuickBooks Online.
Right now, merging two different QuickBooks Online subscriptions are unavailable. You may need to record the year-to-date payroll data into the account you're currently using in the system.
For more insights on adding prior payroll, I'm adding the article I recommend on this:
Set up a prior payroll.
Please know you can also move your lists from another QuickBooks Online using CSV or Excel file format. In case you need the steps, I'm also adding the link down below:
Move your lists to QuickBooks Online.
As always, the Community is here if you have any additional questions related to your subscriptions. Wishing you a safe and wonderful weekend.
