W-2 Efile

If by BSO you mean this: https://www.ssa.gov/bso/services.htm , then yes e-filing W-2's from within QuickBooks sends them to the SSA and then you're done filing.

Welcome to the Community space, @Cside.

Let me add info about QuickBooks E-filing and the new BSO W-2 filing. 

To verify if there's a need to file a W-2 via Business Services Online (BSO), I recommend contacting SSA. They can give you the exact info you need. 

On top of that, a report that's tailored for BSO is unavailable in QuickBooks Desktop (QBDT). We need to manually run tax and wage summary reports. 

Here's how: 

1. Go to  Reports and select Employees and Payroll.
2. Select Payroll Summary.
3. Adjust the date range appropriately.
4. In the Show Columns dropdown, select Employee.
5. Choose Customize Report tab, then Filters tab.
6. In the Choose Filter section, scroll down to select Name from the filter list.
7. From the Name dropdown, select the employee.
8. Select OK.

Feel free to read this article for more info: Create a payroll summary report in QuickBooks. 

Additionally, here's an article you can read about printing W-2 and W-3 forms. 

You can always come back here, @Cside, if you have additional questions about filing your W-2 forms. I'll be willing to help. Keep safe and have a good one.

I can share some information about e-filing W-2s to the SSA and state through QuickBooks, @sawinland. 

You can create your W-2s and file them electronically with QuickBooks Desktop Payroll Enhanced. If you're subscribed to QuickBooks Desktop Payroll Standard or QuickBooks Desktop Payroll Basic, you'll need to file your state W-2s and W-3 manually by January 31 outside QuickBooks. 

You can e-file your Federal W-2s to the SSA and state by setting up the enrollment for e-filing from the Payroll Center. Then, create the W-2s from the Employees menu. Once done, you can now send us your W-2s to file electronically. From here, you can print your W-2s and send them to your employees or upload your W-2s to QuickBooks Workforce for your employees to view. 

Here's an article that provides detailed guidance with filing W-2s electronically and manually depending on the payroll product used. It also provides step-by-step instructions on setting up W-2 e-filing, creating, and sending W-2 forms: File your W-2 and W-3 forms. 

You can also print W-2s to send paper copies to your employees, for your records or a W-3 to send to your accountant. Refer to this article for more information: Print your W-2 and W-3 forms. 

Please let me know if there is anything else I can help you with regarding W-2s. I'm always here to assist you. Have a great day!
