Moved to New State; Boxes 16 vs. Box 1 on W2

Hello - Assuming the following scenario,

 

  • I was a permanent Resident in State A from January through June (6 Months)
    • My Employer was also located in State A
  • I moved to State B, and was a permanent resident in State B from July through December (6 Months).
    • I continued to work remotely (in State B) for the same employer.
  • I had Box 1 wages of $100K
  • Assume State A should recognize 50K in gross income, and State B should recognize 50K in gross income.
  • However, in Box 16, my W2s show 60K to State A, and 40K to State B, due to the timing of when addresses and such were updated in my employer's payroll systems.
  • So, State A's Box 16 is over-stated by 10K, and State B's Box 16 is under-stated by 10K.

 

Is this a case where,

A.) I should try to get a corrected W2, that shows my Boxes 16 having 50K & 50K?

B.) Or, is this a very common scenario that is simply reconciled when I file my return? I.e. when filing in the two states, I adjust my federal AGI to properly show the 50K that was earned in each state.

C.) If the answer to B is "Yes", should I attached a supplementary explanation or something to explain the discrepancy?

 

Thank you for any guidance!
