State and local agencies treat notices, assessments, and audit letters as legal correspondence with strict response timelines. Using your registered business address ensures continuity and alignment with how jurisdictions expect to communicate. Zamp’s AI-powered platform then tracks, classifies, and manages each notice so deadlines and responses are handled correctly.
Zamp combines intelligent automation with tax specialists to receive, triage, and resolve notices directly with agencies. Notices are reviewed, responded to, and closed out with full filing and nexus context, so your team isn’t interpreting letters or managing deadlines.
Data is reviewed and reconciled by tax professionals, with AI-enabled anomaly detection and validation, so discrepancies are investigated and resolved before submission.
Zamp prepares audit-ready documentation, supports nexus and filing positions, and communicates directly with jurisdictions, reducing the operational and risk burden on your finance team.
It means one integrated system and one accountable team own registrations, filings, remittance, notices, and audit readiness—rather than splitting responsibility between a tool and external service providers.
Pricing is designed to remain predictable as footprint and complexity grow, covering filings, registrations, and ongoing compliance without per-state or per-filing cost escalation.
Your team reviews and stays informed. Execution—registrations, filings, remittance, notices, and audit support—is handled by Zamp’s specialists and platform.
Historical data is migrated, current obligations are validated, systems are connected, and filings continue without interruption. Most teams are fully live within a week.
