Tax Data Systems and StrikeIron have teamed up to provide sales tax rates using a lookup functionality.

The Sales and Use Tax Rate  Premium Web Service provides a programmatic interface to live sales and use tax rate data provided by Tax Data Systems. Simply supply a zip or postal code and it will be instantly matched to the general sales and use tax rates at the state, county, and city level.

Now with the Sales and Use Tax Rate Service, there's no need to manage and update a huge tax rate database. With only a zip or postal code, the most current sales and use tax rates are immediately available.
