Hardin County How Ohio Use Tax Works
Use tax is the less-famous companion to sales tax. When a seller doesn't charge Ohio sales tax on a taxable item—extremely common with out-of-state or online purchases—you owe use tax directly to the state at the exact same combined rate you'd pay at home. Ohio legally credits any sales tax you already paid to another state, so you only ever owe the difference, and it never drops below zero.
Use Tax Due = (Purchase × Your County Rate) − Tax Already Paid
Example: Let's look at the numbers. A $500 untaxed purchase used in Franklin County (8.00%) owes $40 in use tax. If you paid $20 of sales tax to another state at the register, Ohio credits it and you only owe the remaining $20.
Worked Examples
$500 untaxed, Franklin (8.00%), $0 paid$500 × 0.08 − $0$40.00 use tax due
$500 untaxed, Franklin (8.00%), $20 paid$500 × 0.08 − $20$20.00 use tax due
$1,200 untaxed, Butler (6.50%), $0 paid$1,200 × 0.065 − $0$78.00 use tax due
$300 untaxed, Cuyahoga (8.00%), $30 paid$300 × 0.08 − $30$0.00 use tax due
