Section 280.115
Jurisdictional Questions
If the Illinois Service Occupation Tax on a transaction is being remitted
to the Department by the serviceman, the serviceman shall also pay Home Rule
Municipal Service Occupation Tax to the Department on the same transaction if
such serviceman's place of business is located in a Home Rule municipality
which has adopted the Home Rule Municipal Service Occupation Tax. If a purchase
order is accepted outside this State but the tangible personal property which
is sold incident to the sale of service is in the inventory of a serviceman
located within a home rule municipality at the time of its sale (or is
subsequently produced in the home rule municipality) then delivered in Illinois
to the service customer, the place where the property is located at the time of
the sale (or subsequent production in the municipality) will determine where
the seller is engaged in business for Home Rule Municipal Service Occupation
Tax purposes with respect to such sale.
