TaxCloud sample osCommerce Integration

TaxCloud is a free, easy-to-use sales tax calculation and remittance service offered by FedTax.  TaxCloud is the only solution created solely to comply with the Streamlined Sales and Use Tax Agreement (SSUTA) at a scale that supports all internet merchants. TaxCloud requires minimal integration effort by the merchant -- our goal is 20 minutes from sign-up to tax collection. It is safe and secure, and it is completely free to merchants.

This module code allows merchants using osCommerce to quickly incorporate TaxCloud's API.

Requires PHP 5.0 - relies on the SOAPClient client. 


1. Back up current installation
2. Unzip taxcloud files into osCommerce installation directory. 
3. To configure the TaxCloud service, log into the osCommerce administration application and navigate to Admin->Locations/Taxes/TaxCloud Settings. Enter your TaxCloud merchant information.
4. TaxCloud requires that the store's address be set up. (Admin->Configuration->My Store->Store Address and Phone)
5. TaxCloud also requires that each product have a "TIC ID" or tax ID assigned. In osCommerce this is done by creating a Tax Class for each TIC ID and assigning a Tax Class to each product. Tax Classes are created in Admin->Locations/Taxes->New Tax Class. Put the TIC ID in the Tax Class title field and a description in the Tax Class Description. 
6. To assign a Tax Class to a product go to Admin->Catalog->Categories/Products->Dbl click on a category->click on Edit->Assign the appropriate TIC_ID to the product from the Tax Class dropdown.

You will need to create a free TaxCloud account at to get an API ID and API KEY which are required for each web service call.

For the VerifyAddress service you will need a USPS UserID, which you can get for free at This is a requirement to be able to calculate taxes accurately.
