If you haven't got around to it, this is very quick. You need to know python programming and have access to a Linux box or Virtual Machine. I used a Chromebook with the Linux beta running and the miniconda3 python distribution, but I'm sure there are lots of ways to skin this cat. You will need the `m4` macro processor (`sudo apt-get install m4`). It wants python3 and so that must be installed.
In a clean directory or wherever you put scratch projects... two projects side by side with:
git clone https://github.com/b-k/py1040
git clone https://github.com/b-k/1040.js
The instructions for running the python are simple... keep doing make which uses m4 macros to pull the data tables from the javascript project into the python project.
Here is the text output from a hypothetical married couple with one child and 93k family income, 7k taxes withheld, and some Traditional IRA contributions.
I might have filled out the questionnaire wrong. It's a glorified calculator but nice work from the contributors. It makes a great baseline for troubleshooting the finer points, and even pointing to the forms that are requisite. I'm also planning to use it to do scenarios involving investments, inflation, and their tax consequences -- using lame-ass assumptions like '2021 taxes remain in force for 10 years'. But if I need to modify the code, it's all there for tweaking. The ability to do quick but accurate tax computations is better than SWGA ... Standard Wild Goose Ass calculations
If you don't like python, the graphical (javascript) version: https://b-k.github.io/1040.js/ (just shows the structure of the calc, and doesn't compute anything I think)
Anyway, nice simple calculator to check your pencil and paper work -- or your accountant's maths.
