Do I have to pay inheritance tax if an out of state relative passes away.

Generally, if there property is located in a state that does not have state inheritance tax, the estate will not have to pay state inheritance tax. The property could be subject to federal inheritance tax if the property exceeds a certain value (I am not sure hat that is, it was over a million dollars a few years ago). So, if there is a house and a bank account, valued at 50k each located in lets say, Florida, which does not have inheritance, the estate does not pay inheritance tax on those assets.
