How do I handle multiple W-2s from the same employer?
If your W-2s have a different Employer Identification Number (EIN) in Box b, enter each one separately. You might get more than one W-2 if you work for an employment agency or your company changed ownership or payroll providers.
If your W-2s are identical down to the last number and letter, just enter one of them. Keep the duplicate with your tax records or securely destroy it.
If your federal wage info in Boxes 1-14 is the same (or blank on one W-2), and the state info in Boxes 15-17 (or local info in Boxes 18-20) is different, you’ll enter both on the same W-2 screen. Enter all the info from the most complete W-2, then enter the different state and local info from the other W-2.
If the only difference is Box 12, enter all the info from the most complete W-2, then enter the different Box 12 info from the other W-2 on the same screen.
