Can I file my pay roll forms (RT-6...) through QB?

Welcome to the Community, @harrodtransport.

Yes, you can! The steps to do this are pretty simple. This can be done by boing to the Taxes menu in QuickBooks Online (QBO). Here's how:

1. In QBO, go to the Taxes menu at the left pane to get to the Payroll Tax page.
2. In the Forms section, select Quarterly Forms. 
3. Click the RT-6 form link, then Payroll Tax.
4. Choose the date range of the form.
5. If you’ve setup e-services before, uncheck the File electronically box. If you haven’t enrolled for e-services, click the View button.
