A secure web app ingests payslips, W-2s, P60s, tax notices, refund details, and income changes, then identifies likely issues such as wrong identifiers, inactive employment records, emergency tax, underwithholding, overpaid social security, or benefit-threshold risk. It generates jurisdiction-specific action checklists, employer or agency message templates, withholding adjustment estimates, document packs, and deadline reminders.

More workers have multiple jobs, contractor income, cross-border tax exposure, and changing payroll arrangements after acquisitions or job switches. At the same time, digitized tax accounts and document OCR make automated triage and guided resolution increasingly feasible.
