I recently ran my payroll and when I went to print my PD7A form there was a balance in the system from the previous month why would that be

Hi mmm272, 

Running payroll with QuickBooks Online is an awesome way to save even more time and effort with your business bookkeeping. Tracking your source deductions on the PD7A is an important step for any small business owner, and I want to make sure everything is being recorded correctly for you. I'll point you in the right direction for support with this. 

It sounds like you're using the Standard Payroll service, however the system isn't designed to leave remaining or carried-forward balances on the PD7A. In this case, you may need to adjust the balance in the Payroll Tax Center. This also may be related to the Temporary Wage Subsidy. 

There's many variables that may be impacting the balance on your PD7A. In order to get the appropriate assistance, I'd encourage you to reach out to our tech support team directly. These agents will be able to navigate your account with you in order to get you back on track. 

I hope this helps. 

Cheers.
