Streamlined Sales Tax (SSTP)

Developers in the Information Systems Division of the Vermont Department of Taxes are actively developing Free / Open Source Software for Streamlined Sales Tax. All of the results of development (programs, documentation, source code, software designs, etc) will be made publicly available through this site. The goal is to build a generic Streamlined Sales Tax gateway that can be re-used by many states to accept Streamlined Sales Tax registrations and returns. Returns Processing (RP) functionality will be developed by each state. Development is being done in the Java programming language.

Current Status

Vermont has been using this software in production since early 2007 to accept Streamlined Sales Tax registrations and returns. The code is currently undergoing a major revision in preparation for SST2009V02. The latest incarnation of the software can accept and validate returns and registrations. Receipts and acknowledgements are correctly generated. The only remaining tasks are to complete the interface between Vermont's existing tax system and develop more unit tests.

Getting the Code

Older version can be found on the download page. The latest development code can be checked out from subversion using the following repository URL:
