Problem
Traditional tax preparation software was built for a desktop era of disconnected systems and manual data entry, forcing accountants to spend hours retyping information and moving data between tools. This fragmented workflow slows down preparation, increases error risk, and contributes to a profession where CPAs are exiting faster than they can be replaced.
Solution
Luca IQ rebuilds tax software from the ground up as an integrated platform that takes a client from intake to a review-ready 1040 in minutes. The platform combines a client portal, document collection, workpapers, review tools, a deterministic tax engine, e-signatures, and delivery in a single system. A human reviewer always examines every return before delivery, and the engine's deterministic math guarantees identical outputs for identical inputs. For developers, Luca IQ offers a single API that submits structured tax data and returns completed returns as JSON, PDF, or IRS MeF XML, allowing firms to build custom workflows or AI agents without building a tax engine themselves.
Target Audience
Primary customers are accounting firms and tax preparation practices, including firm owners and professional preparers, who need to streamline client intake, preparation, and filing workflows. The platform also targets developers and software companies building tax applications who want to leverage a modern tax engine through an API.
