Pennsylvania has an inheritance tax which is an excise tax on the receipt of inherited property by a beneficiary.
Extra! Extra! Read all about it! A new law that ends the Pennsylvania inheritance tax on family farms was part of the 2012-13 state budget package. Governor Corbett signed the Act on July 2nd. The repeal of the inheritance tax on certain farms is effective for the estates of decedents dying after June 30, 2012.
There is some talk from PA state legislators about repealing the PA inheritance tax. See Neil Hendershot's blog post here.
