Current, Positionally Accurate Tax Jurisdictions
CoreLogic Sales and Use Tax data incorporates up-to-date tax jurisdiction information with detailed municipal boundary files for all 50 states, as well as the 32 states that have local special tax districts. Additionally, CoreLogic collects and regularly maintains sales and use tax information to comply with state and local regulations, and also municipal boundary changes. Because CoreLogic tax layers use parcel level location intelligence to determine the tax jurisdiction, errors often resulting from solutions that use only a ZIP code or ZIP+4 lookup do not occur.
Without comprehensive tax jurisdiction information, the accurate determination of taxes is difficult – and if not billed and properly remitted, can create costly liabilities. In many industries, taxes are collected based upon the physical location of the service address. Or, in the case of on-line retail sales, the physical location of the delivery address. Our research shows that, on average, 25% of municipal boundaries have changes that occur each year adding time-consuming research to a company’s accounting staff.
Manage Your Business, Not Tax Boundaries
Tax jurisdiction information is only meaningful if it is up-to-date. Updated quarterly, CoreLogic Sales and Use Tax data incorporates the nation’s largest parcel dataset - ParcelPoint® - the most extensive parcel data available in the U.S - to provide the most positionally accurate sales and use tax jurisdiction layers available.
With a staff dedicated to tracking ongoing changes, annexations, and de-annexations, CoreLogic Sales and Use Tax data contains the most current boundary information for all incorporated areas within the U.S. With our commitment to the accuracy and currency of our national parcel database, you can have confidence in the data you are using.

Meet Regulatory Compliance
Taxing authorities often audit large companies to determine their level of compliance in the proper payment of sales, use and property taxes. Geographic imprecision is often the main source of erroneous taxation. Developing a defendable tax audit process with parcel-level data provides companies greater insight into potential areas of concern before an official audit occurs.
Automated Web-Based Tax Jurisdiction Assignments
Through custom correspondence files or by generating a FIPS code, CoreLogic Sales and Use Tax data is compatible with popular sales tax management software. Our tax layers provide the correct tax jurisdiction information, geographic coordinates and the in-city or out-of-city indicator, enabling your current sales tax management software to apply the correct tax rates and tax rules. Our solution, Xiance®, offers affordable and easy access to our comprehensive tax jurisdiction information, right at your fingertips.
