Run compliance as one service.
Plain Dot e-files 1099s, matches TINs against the IRS, collects W-9s, files ACA and Form 720 — software, AI, and licensed experts on one bill. We start with tax; the rest of compliance comes next.
IRS-authorized · IRIS-connected · SOC 2 Type II (in progress) · TINs verified real-time · Trusted by lenders, marketplaces, payroll platforms, and banks
Three things changed at once. We're built for all three.
The IRS is retiring FIRE and making IRIS the default. Most filing software hasn't kept up, and state and federal rules change every week.
AI has dropped the price floor for compliance work. We pass that savings on instead of pocketing it.
Most buyers juggle a 1099 vendor, a TIN tool, a W-9 PDF, an accountant for Form 720, and a consultant for the rest. They want one team.
1099 family. TIN matching. W-9 collection. Form 720. ACA 1095. The rest of the IRIS catalog as it rolls out. E-file enabled end-to-end.
ADA / WCAG accessibility audits with specialist firms. Product testing for consumer brands across FDA, CPSC, and label compliance. FinCEN beneficial ownership. State exemption certificates.
The same capabilities exposed as API Rails — a developer API and a hosted MCP server. Banks, brokerages, marketplaces, and vertical SaaS build on us.
Verify TINs in real time and in bulk.
Match every TIN against the IRS database before you file. Catch mismatches early and cut B-Notices — one at a time or ten thousand at once.
Real-time TIN matching catches mismatches before filing, not months after.
From data import to IRS submission — no XML editing, no portal sessions.
Real-time API response for single TIN lookups against the IRS database.
Software, AI, and people on the same team — not five vendors and a consultant.
