If you're subscribed to QuickBooks Online Standard Payroll, you set up workplace pensions automatically. I suggest reaching out to our payroll support to change the enrollment date. Here's how:
Click Help inside QuickBooks Online.
Enter "I need a human" in the Type something field.
Click Contact a human.
Select Live Chat/Call me back.
However, if you're subscribed to the Advanced Payroll version, you can try these steps to change the date:
Go to Payroll Settings, then select Pension Settings.
Look for the Staging date.
If you're unable to change it, though, I suggest reaching out to our customer care support to guide you.
