If you live in ks and buy a car in Missouri do you pay the sales tax in mo or ks?

Answer 1

You will pay the sales tax in Missouri. However, Kansas may charge a "use tax" (equal to the sales tax) for items brought in from out-of-state.

This is common among all the states; when you file your state income tax, you must declare items purchased from out-of-state and pay the tax.
