What Streamlined Sales Tax Governing Board does
The Streamlined Sales Tax Governing Board (SSTGB) is an interstate governmental nonprofit corporation established around 2000 to administer the Streamlined Sales and Use Tax Agreement (SSUTA) and reduce the complexity of multi-state sales tax compliance. It is headquartered in Westby, Wisconsin, and currently comprises 24 full member states and one associate member state (Tennessee), with representation from state tax authorities and advisory councils including the Business Advisory Council (BAC) and the State and Local Advisory Council (SLAC). The organization functions as a public-sector compact rather than a commercial enterprise and does not generate revenue through product sales; its operations are funded by member states under the SSUTA framework.
The SSTGB's core technology infrastructure consists of four interconnected systems: (1) the Rate and Boundary File System, which delivers standardized state-provided tax rate and jurisdiction databases updated quarterly and indexed by 5- and 9-digit ZIP codes; (2) the Streamlined Sales Tax Registration System (SSTRS), a single online application enabling businesses to register with any or all member states at no cost; (3) the State Taxability Matrix, which documents product taxability categories across member states; and (4) the Uniform Sales and Use Tax Exemption Certificate, accepted across all member states. These systems are complemented by a Certified Service Provider (CSP) program through which six contracted vendors—AccurateTax, Avalara, Avior, Exactor, Sovos, and TaxCloud—deliver free sales tax calculation, reporting, filing, and remittance services to qualifying volunteer sellers (remote sellers without physical presence in a member state). CSPs are compensated under contracts with member states rather than through fees charged to sellers.
The SSTGB's primary users are remote sellers and e-commerce businesses that must collect and remit sales tax in states where they lack physical presence following the U.S. Supreme Court's June 2018 decision in South Dakota v. Wayfair, Inc., which validated the SSUTA simplifications as sufficient grounds for economic nexus enforcement. Member state tax authorities are the secondary constituency, using the SSTGB infrastructure to standardize rate administration, exemption documentation, and taxability classification. Distribution is conducted through the streamlinedsalestax.org portal, email listservs for rate-file updates, periodic Governing Board and committee meetings, and a modest LinkedIn presence; there are no traditional go-to-market channels or paid marketing activities.

Streamlined Sales Tax Governing Board competitors and assessment
Company assessmentDirect peers
- Avalara: One of six Certified Service Providers contracted with SSTGB member states to provide free sales tax calculation, reporting, filing, and remittance services to volunteer sellers. Avalara operates a leading commercial sales-tax automation platform that directly consumes SSTGB's Rate & Boundary Files and competes in the same end market.
- Sovos: Contracted Certified Service Provider under the SSTGB framework, providing sales tax compliance services for volunteer sellers in Streamlined states. Sovos operates a tax compliance platform that integrates SSTGB's standardized rate and taxability data.
- TaxCloud: Certified Service Provider within the SSTGB program offering free sales tax calculation and filing for volunteer sellers in Streamlined states. TaxCloud is purpose-built around the Streamlined framework and is one of the most aligned commercial implementations of the SSUTA.
- AccurateTax: Contracted Certified Service Provider under SSTGB, delivering sales tax calculation, reporting, and remittance services for remote sellers in Streamlined member states. Operates in the same compliance-services market as SSTGB-orchestrated CSPs.
Broad incumbents
- Vertex, Inc. Established indirect-tax software provider offering enterprise-grade sales tax calculation, filing, and compliance solutions. While not an SSTGB CSP, Vertex competes for the same enterprise sales tax workload and indirectly relies on state rate data SSTGB helps standardize.
- Thomson Reuters (ONESOURCE): Major tax compliance software suite covering sales and use tax determination, filing, and reporting for multinational enterprises. Operates in the same sales tax compliance category but serves a broader enterprise and global tax portfolio than SSTGB's narrow state-tax scope.
- Wolters Kluwer (CCH / SureTax): Provides sales and use tax compliance software (SureTax) as part of its broader tax and accounting portfolio. Competes with SSTGB-anchored CSP offerings for the enterprise and mid-market sales tax automation workload.
- ADP: While primarily known for payroll, ADP offers tax compliance and filing services that intersect with sales tax for small and mid-sized businesses. Operates in adjacent tax-services territory with overlapping customer segments but a much broader product portfolio.
Others
- Federation of Tax Administrators (FTA): National organization supporting state tax administrators — a peer interstate/governmental body listed as a partner on SSTGB's website. Not a competitor but a closely related ecosystem participant in the same state tax administration domain.
- Multistate Tax Commission (MTC): Interstate compact supporting state tax agencies on multistate tax issues; listed as a national partner on SSTGB's website. Operates as a peer governmental body in state tax administration rather than a direct commercial competitor.
