W2Fixer

W2Fixer is a web + mobile app that audits your W-2 and paystubs for common, expensive tax issues before you file: missing/incorrect state withholding, multi-state work mistakes, HSA/FSA coding problems, dependent care limits, retirement contribution mismatches, and duplicate employer entries after job changes. You upload PDFs or connect payroll providers, then the app generates a plain-English “fix list” you can send to HR/payroll (with prewritten emails and the exact boxes/fields to correct). It also estimates the potential refund impact and flags situations where you should talk to a CPA (e.g., residency disputes). This is not a full tax filing product; it’s a pre-filing error detector and documentation organizer that reduces back-and-forth, amended returns, and surprise tax bills.
