Partial The prep and calculation UI for SA100 to SA110 forms is vibe-codeable, but filing through HMRC requires official software recognition and an HMRC API integration, and tax calculations must be correct under a regulated process.
What it would actually take: Build a web app with a guided form flow, a tax calculation engine encoding current UK rules, and PDF/XML output. The hard parts are HMRC software recognition and the Making Tax Digital submission APIs, which need formal developer registration and compliance testing. You also need a qualified tax specialist to verify calculations and rule changes each year, and security and data-protection practices appropriate for financial data.
