You can find your use tax rate by visiting the Kansas Sales and Use Tax Locator.
Example: A Kansas resident orders a computer from a company in New York over its website. Total cost for the computer is $2,000 plus $10 shipping. This person will owe 8.95% (current sales tax rate where the person lives) Kansas use tax on the total cost of $2,010. $2,010 X .0895 = $179.90.
