Could you build this?
No Requires encoding tax-form logic for 1040, 1120-S, 1065 and 1120 with source-linked workpapers that CPA firms will rely on, which demands deep tax expertise and accuracy that vibe coding cannot supply.
What it would actually take: A real version needs tax practitioners who can encode IRS form logic and year-specific rule changes, plus a verified rules engine and audit trail for workpapers. The hard part is correctness and liability, not the UI. Credibility with CPA firms also requires domain expert review and ongoing maintenance each tax season.
