I'm trying to enter historical payroll data for a called worker, $0 SS and $0 medicare. Is this a possibility?

Yes, it's possible to add your historical payroll data if you haven't run payroll yet, Nathan.

Here's how:

1. Sign in to QuickBooks Online as the primary admin. 
2. Go to My apps from the left side panel, choose Payroll, and then select Overview.
3. Make sure to complete your payroll setup under the Get ready to pay your team task until you're ready to enter the historical data.
4. Click Start next to Add your payroll history.
   
   

If you have already processed payroll, I recommend contacting our Payroll Live Support team. Our live experts will assist you in entering your payroll history.
