Could you build this?
No Automating real US sales tax registration and filings across 50 states requires deep regulatory compliance, legal liability management, and direct integration with fragmented state revenue departments.
What it would actually take: A real system requires an integration engine interfacing with individual state tax portals (often lacking public APIs and requiring RPA or certified vendor channels), combined with a continually updated database of multi-jurisdictional tax codes and nexus rules. The stack would involve a resilient workflow orchestrator (e.g., Temporal), strict cryptographic storage for taxpayer identification, and certified CPA review pipelines. Deep expertise in US state tax law and compliance liability is required.
