Zamp's AI 'Operating System' Tackles Tax and the Talent Crisis

NEW YORK, NY – April 28, 2026 – As the accounting profession grapples with an unprecedented talent shortage, tech firm Zamp has launched what it calls the "Operating System of Sales Tax," a global platform designed to automate and guarantee compliance. The company announced the global launch of Zamp OS alongside a total of $30 million in funding, with the latest round led by Acrew Capital and including a strategic investment from Thomson Reuters Ventures.

The platform aims to provide a lifeline to accounting firms struggling under mounting compliance workloads amid a shrinking workforce. By combining artificial intelligence agents with in-house tax professionals, Zamp is offering more than just software; it's providing a fully managed service that takes complete ownership of the complex sales tax lifecycle, a move that could reshape expectations in the tax technology sector.

A Solution for a Profession in Crisis

Zamp's launch comes at a critical juncture for the accounting industry. Projections indicate that as many as 75% of current U.S. accountants are expected to retire within the next 15 years. This demographic cliff is compounded by a declining pipeline of new talent, with the AICPA reporting significant drops in accounting degree enrollments. The result is a widening gap between the immense volume of compliance work and the number of professionals available to perform it.

This talent crunch directly impacts the ability of firms to grow and serve their clients effectively. According to EY's 2025 Tax and Finance Operations Survey, tax professionals spend nearly half their time—45%—on manual data gathering and organization before compliance work can even begin. Zamp OS is engineered to attack this bottleneck directly. The company claims its AI agents can ingest, clean, and validate years of messy spreadsheets and historical filing data, getting new clients operational in days rather than the weeks or months typical of legacy systems.

The platform's impact on efficiency is significant, with Zamp reporting that it has increased output per compliance resource by a factor of 12. This leverage allows its more than 120 partner accounting firms—including prominent names like Withum, Anchin, and Frank Rimerman—to scale their sales tax practice and take on more clients without a corresponding increase in headcount.

More Than an App: The 'Operating System' Approach

Zamp executives are deliberate in branding their platform as an "operating system" rather than a simple software application. The distinction, they argue, lies in its vertically integrated, end-to-end control of the entire compliance process.

"Three years ago we were only a managed service. Today, we're an operating system — and the difference is infrastructure," said Rohit Bhadange, CEO and Founder of Zamp. "We source our own tax data. We own every workflow. We deploy agents across every step with tax professionals there when it matters."

This vertical integration is a fundamental departure from the prevailing market model. Many existing tax compliance tools are built on top of third-party tax rate data and provide automation that the client must still configure, manage, and ultimately assume liability for. John Gardner, Partner at Acrew Capital, emphasized this distinction. “Zamp took a fundamentally different path. They built their own tax data layer across 12,000-plus jurisdictions, own every workflow from registration to filing to notice management, and pair AI agents with real tax professionals at every step," he stated.

This approach means Zamp handles everything from determining where a client needs to file (nexus), registering with state authorities, calculating taxes with rooftop-level accuracy, managing exemption certificates, and handling any notices from tax jurisdictions. This contrasts sharply with self-service competitors like TaxJar, now part of Stripe, or even larger enterprise players like Avalara, where the ultimate responsibility for accuracy often remains with the customer.

A Guarantee That Changes the Game

The confidence Zamp has in its vertically integrated model is embodied in its most compelling feature: an accuracy guarantee. The company pledges that if its system makes an error resulting in a penalty, Zamp will cover the cost. This commitment to "own the outcome" directly addresses one of the biggest pain points for businesses and accounting firms navigating the labyrinth of sales tax regulations.

The company can make this guarantee because of the tight control loop between its AI and human experts. The platform has already remitted over $300 million in sales tax, completed more than 100,000 on-time filings, and handled over 75,000 notices, all while maintaining a 99.97% filing accuracy rate. This track record, combined with a 97.8% client retention rate, suggests the model is resonating with its partners.

"As an advisor who works closely with taxpayers navigating the complexities of sales tax, we consistently recommend Zamp," said Courtney Easterday, MSA, SALT Senior Tax Manager, Indirect Tax at Withum. "Their deep expertise, responsiveness, and unwavering commitment to supporting Withum's clients make them an exceptional partner. Zamp's team goes beyond compliance — they provide the clarity and confidence our clients need in an increasingly complex tax environment."

Strategic Backing for Global Ambition

The investment from Thomson Reuters Ventures is a powerful endorsement of Zamp's strategy. As a corporate venture arm of one of the world's leading providers of tax and accounting information and technology, its backing signals a belief that Zamp is solving a core industry problem.

"In accounting and tax compliance, firms are facing a talent shortage and the work is not slowing down," said Tamara Steffens, Managing Director, Thomson Reuters Ventures. "Zamp has built a vertically integrated platform where AI agents empower tax professionals to work fast and guarantee the outcome together. That's the infrastructure layer this industry has been missing."

This strategic backing supports Zamp's global ambitions. The platform already provides sales tax coverage in over 100 countries in addition to all 50 U.S. states, making it a viable solution for e-commerce companies and other businesses expanding into new domestic and international markets. For accounting firms, this opens the door to offering global compliance services without needing to build an international practice from scratch. The system provides partners with full visibility into every step of the process through a central dashboard, demystifying a process that has traditionally been a black box for clients.

With its fresh funding, strategic partnerships, and a model that directly confronts the industry's most pressing challenges, Zamp is positioned not just to sell a product, but to fundamentally alter how businesses and their advisors manage the ever-growing burden of sales tax compliance.
