What do the letter codes in Box 12 of my W-2 mean?

Here are some tips for deciphering the Box 12 codes on your W-2 form:

  • The UPPER-CASE (capital) letters in Box 12 stand for different things and are listed below. These are the letter codes you'll need to enter into TurboTax.
  • The lines labeled 12a, 12b, 12c, and 12d (sometimes listed as 12a-d) on your W-2 are just line labels, not codes. Don't enter these line labels. For example, if you see "D" on line 12a, enter "D" in TurboTax, not "a". And if line 12a is blank, don't enter anything.
  • Likewise, ignore See instructions for box 12 or See instrs for box 12 – TurboTax handles the tax stuff for you.
