If i received an inheritance in 2017, and was required to pay inheritance tax to PA, can i claim this tax payment as a deduction on my federal return

[sdklotz]

can inheritance tax paid to a state be included as a tax deduction on federal return

[Carl]

No, because you didn't pay taxes on the inheritance to the IRS.

No, state inheritance taxes paid are not deductible on a federal income tax return.  See page 155 of IRS Pub 17:
