Taxwire lands $25m to automate global sales tax. July 2, 2026 Taxwire, a sales tax platform and managed service that takes full ownership of a business's indirect tax obligations, has secured $25m in funding to expand its compliance infrastructure. The round was led by Headline, with XYZ, Vinyl, Recall Capital, Nomo Ventures and Analog Ventures also taking part. Hundreds of strategic angel investors joined the raise as well, among them CFOs, controllers, founders and tax specialists, a number of whom are already Taxwire customers. The scale of the challenge Taxwire is targeting is vast. American businesses hand over upwards of $600bn in sales tax annually, while VAT collected worldwide amounts to roughly $5tn each year. According to the company, the burden of managing this typically falls on finance leaders such as controllers and VPs of finance, who are rarely tax specialists and are already stretched across monthly closes, payroll, audits and board reporting. A typical business generating between $20m and $500m in revenue must handle filings in over 40 states and a dozen or more countries, where mistakes can trigger penalties and back taxes running into the millions, alongside legal costs to fight audits. Taxwire argues that existing solutions have failed these teams. It describes legacy providers as costly, opaque systems designed for a previous era, while newer self-serve tools built for small operations break down when faced with complexity such as mixed B2B and B2C sales, exemption certificates, shifting nexus obligations and cross-border VAT rules. Taxwire manages indirect tax from registration through to remittance in every jurisdiction globally. The platform is powered by an AI-native tax engine that learns from a customer's own invoices and applies taxability rules line by line, with every filed figure traceable to a source that can withstand auditor scrutiny.
