Lesson 5.4 Sales Tax
Student Guide
Many states, cities, and counties charge a sales tax on certain items. Sales tax is a percentage of the price
of an item or a percentage of the total of all taxable items. Sellers collect the sales tax from consumers for
the government. Sales tax rates differ from community to community and state to state. What is the sales
tax rate where you live?
Sales Tax Rate x Price of Item = Sales Tax
Sales tax is rounded to the nearest cent. If more than one tax is charged, the two are often combined. For
example, the state charges a tax rate of 6% and the city charges a tax rate of 2%. The total tax collected
would be 8%. The buyer pays the price of the item plus the sales tax.
Price of Item + Sales Tax =^ Total Cost of Item
Example
Brent purchased a chain saw priced at $285.99. The state in which he lives charges a 6.5% sales tax
on purchases. What sales tax is paid and what is the total cost of the chain saw to Brent?
Solution
$285.99 x .065 = $18.58935, or $18.59
$285.99 + $18.59 = $304.58
Nontaxable Items
In some states, items such as food, prescription drugs, and charges for labor or services are nontaxable.
To find the sales tax when some items are not taxable, first find the subtotal of all taxable items. (A subtotal
is a partial total.) Calculate sales tax on only that portion of the bill. To then find the total of the bill, add the
subtotal of taxable items + the subtotal of nontaxable items + the sales tax.
Sales Tax = Sales Tax Rate x Subtotal of Taxable Items
Total Bill = Subtotal of Taxable Items + Subtotal of Nontaxable Items + Sales Tax
Example
Wylie Chevrolet’s service department took three hours to repair a car. The service charge was $65
an hour. Two parts were replaced at a cost of $117.98 and $49.39. The state has a sales tax of 4%
charged on goods but not on labor. Find the total bill.
Solution
$65 x 3 = $195 (Cost of nontaxable labor)
Add the cost of the taxable parts: $117.98 + $49.39 = $167.37 (Taxable items)
Multiply the sales tax rate by the subtotal of taxable items: $167.37 x .04 = $6.69 (sales tax)
Total Bill:
Nontaxable labor + Taxable items + Sales tax
$195 + $167.37 + $6.69 = $369.06
