- Sales Tax Data—STC offers
regularly updated data files with sales and use tax rates by ZIP code for the
entire United States, as follows:
|$1,265 per year for||four quarterly updates|
|$1,890 per year for||twelve monthly updates|
The data format is a simple, fixed-length text file containing approximately
40,000 U.S. ZIP Codes, one record for each including the ZIP code,
state abbreviation, county name, city name, and the general sales and use tax rates for the state, county, and city levels.
The county level may include any regional or district taxes that have been added in that area.
(see data file format, the license agreement, and a sample file)
The periodic updates include two files--the first with one record per ZIP code and the second with possibly multiple records per ZIP code enumerating the various names and rates that might apply within each ZIP code.
After subscribing, you will receive periodic notices sent to the email address registered with
your account with instructions for where to download the updated and complete file from our FTP
site and the current password to unlock the compressed ZIP file.
We do not have nor can provide any historical data, and under no circumstances do we give out our data for "free" for any requests for "research".
- Automated—Merchants wanting to
perform automated or programmatic calculations will need to integrate our TaxCalc software interface module that will connect
your business system directly to our servers to calculate rates. The
license to use an automated interface that connects to our servers costs $675
and also requires a minimum annual subscription which starts at $230 per year for up to 3,600
calculations (1st year included with the license fee), with expanded subscription levels as follows:
In either case, the tax rates are calculated in real-time with an SSL
connection to our high-speed, secure servers so the results are always 100%
current and accurate.
