Thanks TaxGuyBill! Couple of clarifications -
1. Is there IRS guidance on the topic of which W-2 boxes should be updated in this scenario?
2. Is a W-2c mandatory even if I reimburse the Medicare taxes that my employer paid (it's only a nominal amount)? Social Security isn't applicable as the paycheck in question was late in the year and I was maxed out on Social Security by that time.
