Open-source IRS tax forms become machine-checkable data
What is A proof-of-concept formalization of the IRS federal tax forms?
The us-tax-model repository encodes every line of US federal individual tax forms as structured YAML with precise citations to IRS publications. An interactive interview asks the user relevant questions, selects the right forms, computes the numbers, explains each field, and outputs a printable values sheet, all locally without sending any data.
Who it is for
Tax-software developers and DIY filers can audit, extend, or build on a transparent, verifiable representation of the IRS’s published procedures.
