taxes.cue

tax organizer, calculator, and toolkit in CUE

taxes.cue lets you collect all your tax data for a given year into a single human-editable version-controllable text file, written in cue.

the data is structured and validated using cuelang types, and can easily be converted into for export into other systems.

included in taxes.cue are conversion "functions" to summarize your data into other formats:

• a text based report that can be used to fill out forms by hand
• a json structure used by freefilebot to enter your tax data into https://freefilefillableforms.com

$ brew install cue # or equivalent, see cuelang.org
$ git clone https://github.com/tmm1/taxes.cue

status

this project started as an experiment to learn cuelang, but has quickly grown to more than a simple prototype. cue has proven to be a powerful tool for this use-case, and is surprisingly mature. as a result development is progressing quickly and taxes.cue already has several useful pieces. however, do note that many basic tax calculations are not implemented yet. as such, this project is more akin to a "json spreadsheet", optimized for someone who knows their way around the tax filing ecosystem. if you need something like turbotax which will do your taxes today, check out https://ustaxes.org
