Pennsylvania Inheritance Tax, Taxable Property
All of the real property and tangible personal property located within the state and owned by a Pennsylvania decedent is taxable.

All intangible personal property owned by a Pennsylvania decedent is also taxable, no matter where it is located. This may include, for instance, the value of the cash in a savings account held with a bank that is located in any other state.

Other taxable items include joint property owned with the right of survivorship, as well as certain retirement benefits, IRA accounts, and annuities. Pennsylvania liquor licenses and the value of contracts to sell real estate located outside of Pennsylvania are also taxable. 

It is important to note that the inheritance tax is calculated upon the basis of property transfers and not the method that is used to accomplish the transfer.  This means that joint bank accounts and trusts alone do not avoid or reduce taxes.  This also means that simply using a will does not increase the amount of inheritance tax, as all transfers are subject to the tax, whether the property transfer is accomplished by a will or otherwise.
