Offer a fixed-fee case-resolution service that collects filing records, reconstructs the case timeline, identifies the responsible party, and produces the required correction or escalation package. A trained case manager then coordinates calls, correspondence, amended-return preparation through qualified partners, and refund tracing until the case reaches a defined resolution or handoff.

Tax filing increasingly spans software vendors, identity systems, government portals, and refund-processing banks, creating more failure points and fragmented accountability. The signals show buyers already paying for expert assistance but still lacking effective post-filing case ownership.
