1040Sidekick

1040Sidekick is a web + mobile companion for people who want to file their own taxes but don’t trust themselves to catch every mistake. You import prior-year returns and current-year tax documents, then the app walks you through a structured interview focused on high-error areas (credits, withholding, side income, dependents, and state specifics). An AI engine flags inconsistencies (e.g., missing 1099s, mismatched SSNs, duplicate dependents, suspiciously low withholding) and generates a plain-English “risk report” before you file. The key: you can pay for a quick human review of the final return package (not full prep), with a checklist-style sign-off that highlights what to fix. It’s realistic because it doesn’t try to replace TurboTax; it reduces anxiety and errors for DIY filers and makes “am I missing something?” a productized service.
