Accounting Today reports that Filed co-founder and CEO Leroy Kerry and Crimson Tree Software co-founder and chief engineer Tom O’Sullivan launched the Open Tax Technology Alliance to promote open source software and open data standards in accounting technology, saying proprietary vendors profit from friction and lock practitioners into closed loops. The not-for-profit alliance says its code and standards will never be monetized, and its first releases are Open Tax, a free single-binary Form 1040 calculation engine covering tax year 2025 with 186 registered nodes and 131 input types that runs locally and exports modernized e-File XML, and an open data standard for partnership returns that replaces PDFs with digitized information.
