Installation, Alteration and Special Service Charges
Section 130
Section 130.450
Installation, Alteration and Special Service Charges
a) When Taxable
Where the
seller engages in the business of selling tangible personal property at retail,
and such tangible personal property is installed or altered for the purchaser
by the seller (or some other special service is performed for the purchaser by
the seller with respect to such property), the gross receipts of the seller on
account of his charges for such installation, alteration or other special
service must be included in the receipts by which his Retailers' Occupation Tax
liability is measured, if such installation, alteration or other special
service charges are included in the selling price of the tangible personal
property which is sold. This is true whether the charge for the property which
is sold and the charge for installation, alteration or other special services
are billed by the seller to his customers as separate items (except when the
purchaser signs an itemized invoice so as to make it a contract reflecting the
intention of both the seller and the purchaser), or whether both items are
included in a single billed price.
b) When Not Taxable
On the other
hand, where the seller and the buyer agree upon the installation, alteration or
other special service charges separately from the selling price of the tangible
personal property which is sold, then the receipts from the installation,
alteration or other special service charge are not a part of the "selling
price" of the tangible personal property which is sold, but instead such
charge is a service charge, separately contracted for, and need not be included
in the figure upon which the seller computes his Retailers' Occupation Tax
liability.
c) Cross Reference to Retailers' Occupation Tax Section 130.1940
