This year I got two reference copies of my W-2 from my workplace. One is an employee reference copy, the other is the city/local reference copy.
All of the information on both copies pf my W-2 is the same, except for two things, specifically box 12a and 12b: the numbers under code C and code D differ between the Employee Reference copy and the City/Local Reference copy of my W-2.
What do I go off of when filing my taxes, what should I do?
