Taxwire is a sales tax and indirect tax compliance service for mid-market companies. It pairs a proprietary calculation engine with an in-house tax team. It covers nexus monitoring, registration, tax calculation, return filing and remittance across US states, plus VAT and GST obligations in the EU, UK, Canada, Australia, New Zealand and Norway. The tax team prepares, reviews and submits returns, and also handles historical cleanup and audit defense. The engine calculates at rooftop level across 45+ US states, including home rule jurisdictions. The company says it targets finance teams at companies with $10M to $250M in revenue, including B2B SaaS businesses with multi-state exposure, and that customers reach full US compliance within about a week of onboarding.
