Employer reported imputed income for my husband and won't issue corrected W-2 forms.

I got married in 2016. My husband and I filed as married for 2016, 2017 and 2018. 

We realized at the end of 2018 that the 2016 and 2017 had imputed income for the insurance premiums of my husband.

My employer refuses to issue corrected 2016 and 2017. Are they allowed to refuse that?

If so, how do I file a correction?

Why is it wrong?  If the employer pays premiums for over a certain amount of life ins for you (it was 50,000 might be different now) you have to report the premium for the ins amount over 50,000 as income.   When I worked I kept my coverage at less than 50,000 to not have imputed income.

I'm sorry I answered for life insurance.  Did you mean health ins?

Yes I mean for health insurance. It is taxable if you are non-married partners, but not taxable when married.
