Note on using this project

This project is built by a growing community. If you notice an error in the outputted PDF or any other error, please submit an issue on the Github issues tab. We appreciate your feedback!

User Data

The project is available strictly via client side. Data is persisted to the site's localstorage so no personal information ever leaves the user's computer. For those who want extra security, the codebase can also be built as a desktop application.


Thank you for taking the time to contribute; let's make tax filing free for everyone! 🎉

To ensure the project is fun for every contributor, please review:

Get Started

This application can be run as either a web application or a standalone desktop application

Web application

This project runs on Node 16. To ensure you're on the proper version, we recommend nvm.

With nvm installed, you may select a version 16 node using:

nvm install 16
nvm use 16

To run,

npm ci          # install package dependencies
npm run start   # run app

Note: To avoid having to set your node versions, we suggest using a tool like direnv. With the following configuration file as .envrc in project root:

export NVM_DIR="$HOME/.nvm"

. "$NVM_DIR/nvm.sh"  # This loads nvm
#. "$NVM_DIR/bash_completion"  # Optional, nvm bash completion

nvm install 16
nvm use 16

your environment will be set up every time you enter the project directory.


If preferred, a Docker alternative is available:

docker-compose build
docker-compose up

Open a browser to http://localhost:3000.

To stop and remove running containers, run docker-compose down.

Desktop application

The desktop application is built with Tauri. In addition to the above steps, please follow this reference for setting up your environment for Tauri.

Once your environment is set up for Tauri, run, npm run desktop. To avoid a browser window being spawned in addition to the desktop window, just set the BROWSER environment variable as in: BROWSER=none npm run desktop.

To build executables, run npm run desktop-release.
