What is TIN Comply?

TIN Comply is a vendor compliance platform for accounts payable, tax and procurement teams that need to validate vendors, collect W-9s, screen sanctions lists and prevent 1099 problems before filing. It acts as the validation layer between the point where vendor data enters an organization and the point where it becomes an IRS notice, a B-Notice season or a penalty.

Validations: real-time IRS TIN and name matching; EIN and company lookup, including EIN discovery when a vendor supplies the wrong number; company details lookup; sanctions and OFAC screening against 330+ global watchlists with fuzzy and alias matching; USPS address validation; FATCA GIIN and LEI validation; NPI and Medicare enrollment verification for healthcare payers; FMCSA carrier verification for logistics.

Workflow: a guided electronic W-9 portal with field-level instructions, e-signature, centralized storage, automatic correction outreach and revalidation when a corrected form is returned; bulk file processing for entire vendor populations in one pass; a REST API for ERP, onboarding and finance systems; AI assistant connections through MCP; and reporting with per-vendor audit trails for IRS examinations and internal reviews.

What sets it apart is the result detail. Every check returns the reason a record failed, not a pass or fail flag, so the follow-up asks the vendor for the right correction the first time. Every check is timestamped and exportable, which is the evidence a payer needs for the CP2100 season and a Notice 972CG reasonable-cause response.

Pricing starts at $20 a month, every capability is in every plan, and there is no IRS e-Services enrollment to obtain. The platform runs on ISO 27001, SOC 2 and PCI DSS certified infrastructure. Managed compliance services are available for teams that want TIN Comply to run the program. TIN Comply also publishes free IRS compliance guides, calculators and letter templates at tincompliance.com.
