EXEMPTAX provides software for collecting, validating, and managing sales-tax exemption certificates.
Demand for exemption-certificate management tracks the wider tax-management software market, which one industry study valued at USD 18.9 billion in 2021 and projected to reach USD 32.5 billion by 2026 at an 11.5 percent compound annual growth rate. The same study placed the software, indirect-tax, and cloud segments on the faster-growing side of that market and profiled EXEMPTAX among the vendors covered.
Expanded economic-nexus rules after South Dakota v. Wayfair require remote sellers to collect tax in more states, which pushes certificate collection onto finance and tax teams that often have limited compliance staff. EXEMPTAX competes mostly against broad sales-tax suites, where certificate handling is one module, and against a smaller group of dedicated certificate platforms.
Independent comparisons describe EXEMPTAX as a focused exemption-certificate platform rather than a full sales-tax suite. Reviewers highlight the guided certificate-completion flow, field-level tax validation rules, ecommerce and finance integrations, and managed-service options that can take over collection work for customers.
EXEMPTAX says its subscription platform was built for US businesses that need resale and exemption documents handled end to end, and that it now processes more than a million customer records with same-day setup and an open API. Published comparisons place it against Avalara Certificate Management, Sovos CertManager, Vertex Certificate Center, and Thomson Reuters ONESOURCE Certificate Manager.
EXEMPTAX concentrates on exemption certificate management rather than the broader sales-tax automation stack, so buyers needing tax calculation, registration, and return filing typically combine it with other vendors or choose a full-suite provider such as Avalara or Vertex.
Its public customer references and third-party reviews are concentrated in the United States, and several capabilities that larger suites bundle, such as mail outreach and managed administration, are sold as add-ons rather than included in the entry plan.
EXEMPTAX publishes its price list rather than quoting every deal. A 14-day free trial covers five certificates per month, five nexus states, and one user, while the Standard plan costs $250 per month on a twelve-month term and includes 1,000 certificates per year, all US states, ten users, a Stripe integration, and legacy certificate migration.
Enterprise pricing is quoted on request and adds unlimited certificates and flexible user counts. Optional add-ons include USPS campaigns, custom branding, account management, custom integration, managed services, and outbound call campaigns; the company states that it charges no setup fees and does not require long-term contracts.
