Most retail stores have cash registers that recognize a code such as the Uniform Product
Code (UPC) to determine taxable sales and to calculate the sales tax automatically. The
sales receipt usually shows the total taxable sales as a subtotal, the sales tax, and the total
sales plus tax. Usually, discounts on a sale are subtracted from the sale price before the tax
is figured. Shipping and installation labor charges are generally not taxed.
EXAMPLE B
A customer living in a city with a 6% state sales tax and a 1.5% city sales tax purchased a
refrigerator regularly priced at $850. He was given a 10% discount. Delivery charges were
$45. What were the amount of tax and the total cost to the buyer?
Discount amount: $850 3 10% 5 $850 3 0.10 5 $85
Price after discount: $850 2 $85 5 $765, or $850 3 0.90 5 $765
Sales tax: $765 3 (0.06 1 0.015) 5 $57.38
Cost to buyer: $765 1 $57.38 tax 1 $45 delivery 5 $867.38
State laws regarding the items subject to sales tax vary. Most states do not tax groceries;
however, most do tax meals served in restaurants. Certain nonfood items also sold in gro-
cery stores (such as laundry detergent) are generally taxed. When nontaxable and taxable
items are purchased together, the register usually computes the total price of items pur-
chased and automatically adds the correct amount of tax for each taxable item. The taxable
items are clearly marked on the register tape along with the total amount of tax charged.
EXAMPLE C
A customer living in a state in which the tax rate is 7% went to a grocery store and
purchased a quart of milk for $1.15, a loaf of bread for $2.79, potatoes for $2.25, and two
taxable items—laundry detergent for $8.49 and fabric softener for $5.30. What was her
total charge at the checkout counter?
Taxable items: $8.49 1 $5.30 5 $13.79
Tax: $13.79 3 0.07 5 $0.9653 5 $0.97
Total: $1.15 1 $2.79 1 $2.25 1 $8.49 1 $5.30 1 $0.97 5 $20.95
SALES TAX AS AN AMOUNT PER UNIT
All of the states and the District of Columbia levy special taxes on gasoline and
cigarettes, usually stated in cents per unit (gallon or pack). State taxes on gasoline vary
widely, from $0.075 in Georgia to $0.285 in Wisconsin; in addition, the federal tax is
currently $0.184 per gallon. State taxes on cigarettes currently range from $0.07 (South
Carolina) to $2.575 (New Jersey) per pack; the federal tax is currently $0.39 per pack.
EXCISE TAX AS AN AMOUNT PER UNIT
An excise tax is a tax assessed on each unit. In some states both the excise tax and the
general sales tax apply to items such as gasoline, cigarettes, and alcoholic beverages. In
such instances, the excise tax may be part of the taxable sales price for general sales tax
purposes. For example, in a certain locality gasoline costs $3.40 per gallon, plus state and
federal excise taxes of $0.48, and is subject to a general sales tax of 6%. The total price
per gallon is $4.11 ($3.40 1 $0.48 excise tax 1 $0.23 general sales tax). The general sales
tax is calculated as 6% of $3.88.
Chapter 11 Taxes 203
11.2 Taxes on purchases (sales and
excise taxes) fall into two distinct
categories:financial and social.
Financial sales taxes are those
designed to be borne equally by most
of the adult population,such as taxes
on food and general merchandise.
Social sales taxes target segments of
the population that use certain items,
such as cigarettes and alcohol.
