Retirement tax questions

Generally inheritance is not taxable income to you.

"The Basic Rule: Inheritances Aren't Taxed  as  Income . An  inheritance  can be a windfall in many ways—the inheritor not only gets cash or a piece of property, but doesn't have to pay  income  tax on it. "

The big exception I see on this is retirement accounts, where the 1099R is taxable income to who inherited it.  

Please make another post with more detail if this does not answer your question.
