What TINCheck LLC does

TINCheck LLC is a tax identity verification platform that provides real-time, bulk, and API-based Taxpayer Identification Number (TIN) matching against the IRS database and 20+ global watchlists including the OFAC sanctions list, Death Master File, FBI Wanted, EU Sanctions, and Interpol. The service enables businesses to validate TIN/name combinations for vendors, contractors, gig workers, and customers during onboarding and prior to filing 1099s, helping them avoid IRS B-Notices and per-record penalties. TINCheck operates three core products: TINCheck Real-Time for instant single-record verification, TINCheck Bulk Match for CSV/Excel batch processing with results returned within 24 hours, and a REST/SOAP API that embeds real-time validation into existing onboarding and back-office workflows. The platform maintains a cache database of over 20 million records refreshed every 30 days to ensure service availability when government systems are down, and is supported by enterprise-grade security certifications including SOC 2 Type II and ISO 27001.\n\nTINCheck is a wholly-owned subsidiary of Sovos Compliance, LLC, a larger tax compliance and regulatory reporting vendor that provides enterprise infrastructure, global data centers, and government relationships. The company's go-to-market is primarily API-first and product-led: customers can sign up online, run a free first check, and choose between monthly subscription plans (ranging from $19.95/month for 25 verifications to $1,299.95/month for 5,000 verifications) or prepaid credit packages offering lower per-check costs. Enterprise customers requiring more than 5,000 monthly verifications can access custom pricing through a sales-assisted motion, and the TINfluence referral program provides 15% commission for 3 months per referred customer.\n\nThe company serves seven primary verticals: Financial Services, Enterprise Services, Higher Education, Insurance, Retail & eCommerce, Technology & Software, and Identity Verification Platforms. Its geographic market is concentrated in the United States, though EU-US, UK Extension, and Swiss-US Data Privacy Framework certifications indicate capability to serve European customers. The company was founded in 2009, employs 11-50 people, and is incorporated in the Commonwealth of Massachusetts, with offices in Wilmington, MA and a Calabasas listing in firmographic data.

Direct peers

• Wolters Kluwer (CCH Tax & Compliance): Provides tax compliance and TIN/identity validation capabilities to enterprise tax and accounting teams. Directly comparable because it offers IRS TIN matching, 1099 reporting, and KYC/sanctions workflows embedded in professional-grade accounting platforms used by TINCheck's same buyer personas.
• LexisNexis Risk Solutions: Delivers identity verification, AML/sanctions screening (WorldCompliance), and deceased-person checks. Comparable to TINCheck in core screening categories (OFAC, DMF, global watchlists) and serves overlapping regulated-industry buyers.
• GBG Group (incl. IDology, Loqate): Global identity verification and AML platform offering KYC, sanctions, age/identity, and document verification. Comparable to TINCheck's identity verification and watchlist components, particularly for fintech, IDV platforms, and fintechs needing API-first onboarding.
• Veratad Technologies: Identity-verification and Age/ID verification provider with KYC/AML, sanctions and watchlist checks via API. Comparable to TINCheck's identity verification and sanctions screening use cases, particularly serving similar SMBs and IDV platforms.

Broad incumbents

• Refinitiv / LSEG (World-Check): LSEG's World-Check is the dominant global KYC/sanctions screening dataset. Comparable to TINCheck's watchlist component for AML compliance, though LSEG is broadly a much larger incumbent and not specialized in TIN/IRS matching.
• Equifax Workforce Solutions (The Work Number): Provides employer/employee identity, tax identity services (1099 compliance), and employer verification data. Comparable to TINCheck's enterprise tax-compliance use cases but at much greater scale and adjacent HR-focus.
• TransUnion: Major credit bureau with identity verification and risk information products including fraud, sanctions, and deceased-person data. Comparable via shared identity-data franchise and overlapping regulated-industry buyers.
• Experian: Credit bureau with identity, fraud, and compliance data products used across financial services and enterprise vendor workflows. Comparable in identity-verification and risk-data components of TINCheck's offering.

Emerging players

• ComplyAdvantage: AI-native AML/sanctions/transaction screening fintech focused on fintechs and digital banks. Comparable to TINCheck in OFAC/sanctions screening and API-first delivery model, though stronger in continuous transaction monitoring.

Others

• Sovos Compliance (parent): Parent company of TINCheck and broader suite of tax compliance, 1099 reporting, sales-tax, and regulatory-reporting products. Listed for completeness as the controlling shareholder providing regulatory expertise, infrastructure, and reach — not a competitive peer but the principal strategic and operational counterparty.
