So we built the platform hundreds of companies trust to handle global sales tax and VAT compliance end to end. Today we raised $25M to do it for thousands more.
Trusted by fast-growing companies across industries
"In this world nothing can be said to be certain, except death and taxes."
BENJAMIN FRANKLIN
And they'll probably cure death before they solve taxes.
Indirect taxes, the taxes charged on transactions between businesses and their customers, are the least sexy, biggest problem in almost every company that sells anything. In the US alone, businesses remit more than $600 billion in sales tax every year, and globally it’s ~$5 trillion in VAT every year. This never goes away. It only gets bigger.
Today, we raised $25M to make it our problem instead of yours.
The round was led by Headline with participation from XYZ, Vinyl, Recall Capital, Nomo Ventures, Analog Ventures, and hundreds of strategic angels — CFOs, controllers, founders, tax experts, etc. — several of which are our customers.
Taxwire is the sales tax platform and managed service that owns your indirect tax end to end, from registration to remittance, across every jurisdiction, worldwide. We don't sell software, and we don't sell a service. We sell the outcome: the tax you owe, calculated correctly, filed on time, defensible when an audit comes, and all the accounting & compliance workflows automated.
We raised this round because taxes aren't getting any easier, and someone has to build the infrastructure that keeps companies compliant without making it their problem.
Here's why we're doing it.
Sales tax rates by county — more than 13,000 jurisdictions to get right.
The people stuck with this problem aren't tax experts
The average $20M to $500M business manages sales tax filings across 40+ states and a dozen or more countries. Get it wrong and it costs hundreds of thousands to millions in penalties and back taxes. Then come the legal fees to defend the audit, and the nights your controller spends answering Bob at the New York Department of Revenue.
And the responsibility lands on people who never signed up for it.
Your controller. Your VP of Finance. They aren't sales tax experts. Almost nobody is.
They're closing the books every month, running payroll, getting through the annual audit, keeping board reporting straight, and managing income tax filings. Somewhere in the middle of all that, they're also expected to make high-stakes sales tax calls, stretched thin and under-resourced, with this nowhere near the top of the list.
I know because I lived it. In 2023 I was running finance at the fastest-growing school lunch company in America. We'd raised real money and were scaling fast, delivering fresh food to kids and faculty across the country. It turns out sales tax on food sold through schools, across a B2B and B2C model, gets complicated fast. I was the one who had to figure it out, and the sales tax platforms that were supposed to have the answer didn't.
A century of sales tax, by hand — rung up one key at a time, paid one stamp at a time.
The tools that were supposed to help
The incumbents are black boxes. Expensive and painful to set up. And you could never get a human on the phone who understood your business. That's Avalara, the platform built for a different era that a whole generation of finance teams got stuck with.
The newer tools couldn't help me either. They were self-serve products built for founders, small-business owners, or business with minimal complexity… and they fell apart the moment things got real. Product lines that didn't map cleanly to one of their supported taxable categories. A mix of B2B and B2C sales. Exemption certificates to chase and validate. Nexus tripping in a new state every time we grew. VAT rules the second we sold across a border. None of them were built for any of it.
Either way, it was brutal to get to an answer I could understand and trust with a lean team.
What I actually believe
Every platform can calculate a tax rate. That part is solved.
The hard problem is everything around it. Getting messy, real-world transaction data into a shape where the math even works. Catching the exemption certificate sitting in someone's inbox before it becomes a liability. Handling the state notice that lands the same week your controller is closing the books.
Most tax products, old and new, are built on a shortcut. They assume the inputs are clean and the edge cases are rare. In indirect tax, the edge cases are the job. Get one wrong and you cost a customer money, or hand them an audit. Anyone can automate a tax filing. Few take accountability for compliance. For making sure when the inevitable audit comes — your business is ready.
We built Taxwire for that reality from day zero. Accuracy and depth from the foundation up.
That's the bet.
We built Taxwire for companies that have outgrown their options
Some are stuck in a legacy platform, expensive and opaque, and have been told switching is too painful to bother. Avalara is where most of them are stuck. Others have duct-taped together spreadsheets, a self-serve tool, multiple services firms, and hope, and have hit the ceiling. Either way: a growing pile of filings and edge cases, and no one they trust to own it.
The migration is rarely as painful as they've been told. We've done it 150+ times.
Take AssetWatch. They install wireless sensors in manufacturing plants across the country and bill hardware, software, and monitoring on a single invoice, three revenue lines with a different tax treatment across every state. Their install crews create physical nexus wherever they go, so the map of where they owe tax kept shifting as they grew. They’d been on Avalara, left to figure it out with a four-person finance team. Taxwire took it over end to end: nexus, registrations, exemption certificates, and filing. Today they run 3,800+ filings a year on Taxwire.
"Our crews install sensors in plants across the country, and we bill hardware, software, and monitoring on a single invoice, three lines, taxed three different ways in every state. We migrated from Avalara, and now Taxwire owns it end to end."

What Taxwire actually is
So we built what I wished I'd had. Taxwire is a sales tax platform and a managed service that handles your indirect tax end to end, across every industry, so your finance team can get to a zero-day close and you stop thinking about sales tax.
What you feel as a customer is almost nothing. That's the point. We aim to be the most boring vendor in your stack. You shouldn't have to think about us, and when you do, it's only to see exactly where you stand and why. We keep the lights on. Your inbox stays free of state notices. Your company stays out of audit hell.
Boring is the promise. How we keep it is anything but.
Underneath is an AI-native tax engine. It learns from your own invoices and applies your taxability rules line by line, even when a single order has hundreds of items that each tax differently. Every number we file traces back to a source you can put in front of an auditor, not a black-box estimate you take on faith.
It handles the unglamorous parts too. It reads and files your exemption certificates and warns you before one lapses. Your team approves the calls that actually matter, from Slack or email. No portals, no logins.
The software is the engine. The service is the guarantee that it works.
