Precise Sales and Use Tax Rates

Ensuring your business uses the correct sales and use taxes starts with an address and access to up-to-date rates. FastTax has both.

Valid addresses equal accurate tax rates

Our FastTax service starts with our certified Address Validation engine, establishing valid addresses to ensure correct tax rates for both US and Canada. Using the address, the service also identifies incorporated and unincorporated areas, which is essential for areas that have multiple tax jurisdictions.
