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
