One of the other counselors at the TaxAide site I volunteer at saw this. (It was a different day than I volunteer so I haven't seen the W-2 in question):
[Taxpayer] also got a large life insurance payout in 2011, all taxable, on a W2 form (like salary) after her husband's death in 2010. [Taxpayer] has challenged the bank [presumably the decendent's employer], but always gets the answer it's taxable.So what could make this taxable? Even when the employer pays 100% of the premiums, the imputed value of the coverage is taxable income to the employee, so why would the payout be taxable? Can this happen when it's some kind of non-group or otherwise special policy?
