61 Pa. Code § 31.27
(d) Rentals of property by funeral directors. Morticians and funeral directors who rent property to others shall register and collect tax with respect to such rentals. Use of property in conjunction with a funeral service performed by the person owning the property shall not be deemed to be a rental. If a separate charge is made for rental of specific items, the tax applies.
Example: A funeral director who on occasion rents a hearse or other equipment to another funeral director shall register and collect tax upon the rental. The funeral director shall also pay tax when he purchased the hearse since it was not purchased for use predominantly in a rental business.
