What TIN Comply Offers
In today’s rapidly evolving regulatory landscape, accurate and efficient TIN matching is essential. Traditional systems offer only basic pass/fail results, leaving you with no means to correct errors or gain actionable insights. TIN Comply revolutionizes the process by delivering advanced validation capabilities that go far beyond conventional methods.
The Problem With How 1099 Compliance Actually Works
Most organizations collect a W-9 and assume the job is done. The vendor certified their information under penalty of perjury — that should be enough. It isn't. A sole proprietor who puts their business name on Line 1 instead of their legal name. An EIN with a transposed digit. A legal entity that restructured two years ago and nobody got an updated W-9. None of these are visible in normal AP operations. All of them surface as CP2100 mismatch notices after the 1099 is filed — with B-Notice deadlines running and per-form penalty exposure accumulating.
TIN Comply is the validation layer between the point where vendor data enters your organization and the point where it creates an IRS problem.
What Makes TIN Comply Different
The IRS TIN matching tool tells you a record failed. TIN Comply tells you why — name mismatch, wrong TIN type, invalid TIN — so outreach asks for exactly the right correction.
IRS TIN Matching
250+ lists — OFAC, FinCEN, BIS, EU, UN — screened automatically with every TIN matching call. Fuzzy matching and alias detection included. Not a separate step.
Sanctions & OFAC Screening
Guided electronic W-9 portal with field-level instructions, e-signature, and centralized storage. When a match fails, correction outreach goes out automatically and revalidation runs when the corrected W-9 comes back.
W-9 Management
Know what the IRS actually has on file for any EIN — not what the vendor thinks it is. Confirm legal entity names independently before contract execution or high-value payment release.
EIN & Company Lookup
Validate your entire vendor population in a single pass. Q4 pre-filing cleanup, post-migration validation, M&A due diligence — categorized exception report with automated outreach ready to launch.
Bulk File Processing
Embed TIN matching and OFAC screening directly in your ERP, onboarding platform, or payment authorization system. Bad data caught before it's written, not discovered after it's filed.
API Integration
Every validation, screening result, outreach communication, correction, and revalidation logged to the per-vendor record with a timestamp. When a 972CG arrives and abatement requires evidence of reasonable cause, the documentation is already there — not reconstructed retroactively under penalty deadline.
Reporting & Audit Trails
Also Worth Knowing
Every member of your team — AP, tax, compliance, procurement — gets full access to validations, audit trails, and reporting. No per-seat limits.
Priority support with guaranteed service levels. When B-Notice deadlines are running, you need a vendor that answers quickly.
No lengthy setup processes or unnecessary data requirements. Most teams are validating vendors the same day they sign up.
How It Fits Into Your Workflow
| Stage | Without TIN Comply | With TIN Comply |
|---|---|---|

| First payment | Payment on unvalidated data | Payment on confirmed, IRS-verified identity |
| Q4 pre-filing | Scramble to find and fix errors under deadline | Bulk validation in October — time to resolve before January |
| January filing | 1099s filed with known or unknown errors | 1099s filed with confirmed name/TIN combinations |
| Spring CP2100 | Hundreds of mismatches, no documentation | Small exception list, outreach records already built |
| 972CG penalty | Abatement documentation assembled retroactively | Per-vendor compliance record already exists |
