Because your W2s are filed electronically with the Social Security Administration, no Form W3 is generated as part of the year end process.
If you want the W3 totals, you can go to My Employees, Forms, W2s and see a summary of all W2s generated by the system. The totals at the bottom correspond with the W3 totals.
In addition, you can view, export or print individual W2s for employees from this menu. You can also sort, filter and export the listing any way you choose!
