## What it is
UsTaxes is a free, open-source tax filing application for preparing and filing the US Federal 1040 form, available as a web app and a standalone desktop application. All data is processed client-side and persisted in local storage, so no personal information ever leaves the user's computer.

## Use cases
- file federal 1040 taxes for free
- prepare US tax return from W2 and 1099 forms
- file taxes without sharing personal data with a third party
- compute capital gains from 1099-B and 1099-DA
- file taxes in a state with no income tax
- generate a printable 1040 PDF with schedules
- run a desktop tax filing app offline

## When to choose
- you want a free, privacy-respecting alternative to commercial tax software
- your income comes from W2s and common 1099 forms and you file a 1040
- you live in a non-filing (no income tax) state or only need the federal return
- you prefer client-side software that never uploads your tax data

## When to avoid
- you need full state income tax returns (only Illinois is partially implemented)
- you have complex tax situations like business income, itemized Schedule A deductions, or foreign income
- you need e-filing submission rather than generating a PDF to mail
- you require guaranteed accuracy for edge cases without professional review
