Prices do not include taxes. Orders inside the state of Georgia are subject to a 6% sales tax. We do not collect taxes on orders to other states or international orders; there is currently no national US sales tax. Most international orders are subject to tariffs or taxes upon arrival. This is collected by the government in the country the order was shipped to, and DIYAutoTune.com has no control over these taxes. We do not have the most up to date information on these tax rates, either, so we recommend checking with your local customs office for the most up to date information.
