Could you build this?
No Luca IQ is an IRS-authorized e-file provider and tax computation engine capable of calculating 1040s and directly transmitting returns to federal and state tax authorities. Building and certifying an e-file transmitter requires rigorous IRS compliance, authorized provider status, and deep tax code accounting expertise.
What it would actually take: Building a real platform requires implementing a deterministic tax rule evaluation engine across federal and 50 state tax jurisdictions, undergoing the extensive IRS Authorized e-File Provider application (including background checks and ETIN/EFIN issuance), and implementing MeF (Modernized e-File) XML schemas and MTOM/SOAP transmission protocols. It requires certified tax attorneys/CPAs and enterprise fintech security compliance (SOC 2, IRS Pub 1075).
