What impact does it have on the employee if they already filed taxes and the HSA EE contributions were NOT listed on box 12c code w? We realized that our W2's only listed the ER's contribution however for the past 3 years it has not included the EE contribution and it should have. We will have to submit W2 corrections however I would like to know what the impact if any will the employee have to deal with in this case? Will they have to amend their taxes for previous years?
