About Us
Built by practitioners with decades of hands-on experience in IRS reporting, TIN compliance, and vendor identity validation — not consultants who studied it.
About TIN Comply
TIN Comply was built by people who spent years inside the compliance problem before they built the solution.
Our founders and team bring decades of hands-on experience in IRS reporting, TIN validation, vendor onboarding, and identity verification — not as consultants who studied it, but as practitioners who lived it. We've seen what happens when vendor data is wrong at filing time. We've worked through CP2100 notice cycles, 972CG penalty responses, and the operational chaos that follows a bad vendor master file. We built TIN Comply because the tools that existed weren't good enough.
Why We Built This
Every January, AP teams, tax departments, and compliance officers across the country discover the same thing: their vendor data is wrong, and it's too late to fix it cleanly.
TIN mismatches. Missing W-9s. Name discrepancies that fail IRS validation. The result is CP2100 notices, backup withholding obligations, potential 972CG penalties, and months of remediation work that could have been avoided with earlier, better validation.
We built TIN Comply to move that validation upstream — before the payment, before the filing, before the penalty. Our platform gives teams the tools to validate vendor identity in real time, collect and confirm W-9s, screen against global sanctions lists, and maintain the kind of audit trail that supports a reasonable-cause defense if a penalty ever does arrive.
What We Do
TIN Comply provides a full vendor identity validation platform used by accounts payable teams, tax departments, compliance officers, payroll teams, fintechs, and the developers who build the platforms they run on.
Real-time validation of TIN and name combinations against official IRS records — before payment or 1099 filing.
Continuous screening against 250+ global watchlists on every validation, with timestamped results logged automatically.
Secure digital W-9 collection, IRS TIN validation against submitted forms, and full audit history for every record.
REST API built for fintechs, marketplaces, and payroll platforms. Embed real-time validation into any onboarding or payment workflow.
Full-service W-9 outreach, CP2100 remediation, vendor master cleanup, and 972CG penalty support — handled end to end by our team.
Every validation, outreach attempt, and result is timestamped and stored — building the documentation record your team needs before a penalty arrives.

Security & Compliance
TIN Comply handles sensitive taxpayer data. We take that seriously.
Our platform is hosted on infrastructure built to enterprise compliance standards, with continuous monitoring, strong access controls, and independent third-party audits. Our data centers are certified under:
International standard for information security management and risk controls
Independent audits validating security, availability, and data protection controls

Our Mission
Make vendor identity validation and tax compliance simple, fast, and defensible — so compliance teams spend less time chasing bad data and more time on the work that matters.
The IRS isn't getting less aggressive. Filing requirements aren't getting simpler. Vendor data doesn't clean itself. We built TIN Comply to give organizations the tools to stay ahead of all three.
