My lawyer says something different. I inherited 50% of my grandmothers estate (other half went to my aunt) and was told we both will pay the same tax. If I was a cousin, niece/nephew, etc.., the % paid would be different.
If she died intestate, then the % of your inheritance is different, but not the tax. The Fed. Govt will get their share no matter what. Do you really think the Govt will collect less of a tax because of the relationship with the decedent? The answer is no. The tax code is clear.
