Accurate Sales & Use Tax Rates By Location Federally Certified and Guaranteed

DOTS FastTax

Our real-time sales and use tax API provides the most accurate and up-to-date tax data for US and Canadian addresses.

This sales tax service provides multiple ways to determine accurate sales and use tax rates by location including street address, postal code, city/state, or city/county/state. Where an address is provided, DOTS FastTax includes our federally certified Address Validation service to establish address correctness and ZIP+4. With location determined, FastTax can identify tax jurisdiction and boundaries, resolve address issues, provide alternate city names, and eliminate problems associated with different rates in incorporated vs. unincorporated areas. Service Objects’ FastTax data is synchronized with states’ updates, ensuring the correct tax rates are charged throughout the year.

For companies that do business across the US and Canada, sales tax software is an absolute must due to the sheer volume of tax jurisdictions involved. Even small businesses can benefit from a sales tax API as local sales tax rates can fluctuate from one city to the next -- and even within a given city if special districts have been created.

    DOTS FastTax is a sales tax API that instantly verifies addresses and pinpoints the correct taxability and jurisdiction assignment. DOTS FastTax sales tax software first validates the address entered, making sure that the address itself is correct and accurate. Typos, syntax errors, and other fixable mistakes are immediately corrected. Thus, with a correct address, the sales tax API can then retrieve the correct sales and use tax information.

    By using the sales tax API, you can instantly take an address and determine the correct city, city district, county, and state along with all corresponding city, city district, county, and state tax rates that apply. The sales tax API also calculates the total tax rate for an address and identifies tax exemptions such as freight, labor, and services, if any.

    Sales tax software takes the guesswork out of sales tax calculation. Instead of relying on wall charts, cheat sheets, or your employees' best guesses, use our sales tax API to validate the address and retrieve the most accurate sales and use tax information based on the customer's true address.

    In addition to ensuring that the correct sales and use tax rate is applied at the time of the transaction, this sales tax API minimizes audit risks. Use our sales tax software to ensure tax compliance and accuracy.

    Our sales tax software provides sales and use tax verification for US and Canadian addresses. As a sales tax web service, our API eliminates hardware costs and software maintenance hassles. DOTS FastTax can be seamlessly and easily integrated with existing accounting systems and eCommerce websites. It is easy to set up and even easier to use. ... Read Less
