Inside the build
Built to do the work, not just look the part
An income tax filing engine for Indian returns that never touches the internet.
TaxVault is a tax-filing engine that runs entirely on your own computer, with no network connection at any point in the process. It binds only to 127.0.0.1, your own machine’s local address, and never reaches out to the open internet, so your financial data never leaves your computer.
ITR-1 is mapped end to end. ITR-2, ITR-3, and ITR-4 exist as honest scaffolds under active development, built out piece by piece rather than faked as complete.
Honest by construction
TaxVault does not pretend a return type is supported before the mapping is actually done. Where ITR-1 is complete, it says so. Where ITR-2, ITR-3, and ITR-4 are still scaffolds in progress, it says that instead of quietly producing an incomplete filing and calling it done.

Common questions
Does this send my financial data anywhere? No. It binds only to your own machine’s local address and never makes an outbound network connection, so your data never leaves your computer.
Is every return type fully supported? ITR-1 is fully mapped. ITR-2, ITR-3, and ITR-4 are honest scaffolds, meaning the structure exists and is being completed, not finished filings yet.
Is this available for tax systems outside India? No, this is built specifically around Indian income tax return filing.
