Taxwire

Taxwire is a New York City-based indirect tax company that combines a sales tax and global VAT software platform with a managed compliance service. Its engine performs product tax coding, geocoded real-time rate calculation, registration and automated filing workflows, while an in-house team of tax professionals takes responsibility for judgment calls such as entering a new state, handling an acquisition, or responding to a state audit notice. Coverage spans approximately 22,000 US local taxing jurisdictions and more than 100 countries.

The service covers the full compliance lifecycle: nexus studies, taxability research and compliance audits across jurisdictions where a customer has sales, offices, locations or employees; state registrations and back-filings; tax calculation at invoice and checkout including multi-line invoices, exemption certificates and non-standard product categories; and monthly and quarterly return filing plus remittance, with an audit trail back to source data. Every return is reviewed by in-house professionals before submission. The platform integrates with billing, commerce and accounting systems including QuickBooks, Xero and NetSuite, and exposes an API for custom billing or commerce stacks.

The team is described as including tax engine veterans from Stripe, TaxJar, Fonoa and Avalara, Big Four global indirect tax consultants, and former venture-backed founders and operators. Named staff include co-founder and CEO Andrew Rea, co-founder and CTO Steven Schmatz, a founding PM, engineers, indirect tax subject-matter experts, account managers, a head of tax, a head of registrations operations and a head of growth.

Founding story

CEO and co-founder Andrew Rea has said he encountered the problem in 2023 while running finance at a fast-growing US school lunch company selling B2B and B2C across the country, where sales tax obligations became complex. He found incumbent tools opaque, expensive and slow, with limited access to knowledgeable humans, while newer tools aimed at founders and small businesses broke down at scale, and built the product he wanted as a buyer. He co-founded the company with CTO Steven Schmatz.

Business model

Taxwire sells a combined software platform and managed indirect tax service, charging customers for the compliance outcome rather than software alone. Customers pay a predictable usage subscription covering the platform plus the managed service; reported pricing is a flat annual fee of roughly $12,000 to $15,000 plus per-return fees, positioned against volume-based, per-transaction pricing at incumbent vendors.

Recurring subscription for the platform bundled with the managed service, with per-return fees in addition to a flat annual fee.

Traction

As of mid-2026 the company reported remitting roughly $100M in sales tax annually for customers, processing over $1B in transaction volume, and zero reported customer churn. It serves hundreds of clients, with about half of new customers migrating from a legacy provider and 150+ completed platform migrations. One customer runs 16 entities and about 4,000 returns per year across Shopify, Amazon, TikTok and Faire and was migrated from Avalara in under two weeks; another case cites $200,000 in over-remittances recovered in under three weeks. Ten open roles were listed in mid-2026.

Latest developments

Following the June 2026 raise, the company said it would scale its managed tax infrastructure, expand automated geocoding across global tax systems, and hire data engineering talent. Stated six-month priorities are expanding international coverage, deepening coverage of B2B industries, and owning the workflow between the general ledger and the sales tax provider. The company was recruiting for roles including product and backend engineering, indirect tax research, deployments, partnerships and design.
