What if I buy taxable goods or services in another state, and the vendor charges sales tax for the other state?
If the goods or services were purchased for use in Connecticut and the sales tax you paid to the other state is less than the Connecticut tax, you must report and pay the use tax. Your use tax is the difference between the Connecticut tax and the tax paid to the other state. If the tax paid to the other state is equal to or more than the Connecticut tax, you owe no use tax to Connecticut. There is no refund for tax paid to another state when that state's tax rate is greater than Connecticut's use tax rate.
