Luca IQ is building a modern tax engine for accounting firms.

Nearly every tax return prepared by a CPA in America runs through one of a small number of tax engines built decades ago. Rebuilding that infrastructure means translating tens of millions of words of tax law, regulations, and IRS guidance into software that can calculate returns correctly and consistently.

We're building an API-first tax engine designed from the ground up to calculate, validate, and file U.S. tax returns.

Luca IQ is one of eight IRS-approved tax engines for CPA firms. We’re building the infrastructure that will power the next generation of tax preparation software.
