Instead Gains Full US Government Approval for AI Tax Platform, Challenging Legacy Systems

NEW YORK — The AI-native tax platform Instead announced on May 8, 2026, that it has become the first new tax preparation system in decades to achieve 100% e-file and print approvals across all U.S. federal, state, and local jurisdictions. The milestone completes a multi-month regulatory process, positioning the company to directly challenge established industry leaders like Thomson Reuters’ GoSystem and UltraTax, Wolters Kluwer’s CCH, and Intuit’s Lacerte. The comprehensive government approvals cover all major business and individual tax forms, including 1040, 1041, 1120, 1120S, and 1065. For decades, the professional tax software market has been dominated by a handful of legacy providers, with the complex and lengthy approval process serving as a significant barrier to entry for new competitors. Instead’s successful navigation of these requirements for its AI-driven system marks a notable development for accounting firms and tax professionals. The arrival of a fully-approved, AI-native tax platform presents a significant operational crossroad for accounting firms and the businesses they serve. While the promise of a “zero-touch tax return” is compelling, particularly for reducing manual data entry and speeding up compliance cycles, the transition away from deeply embedded legacy systems is not trivial. In our experience, businesses often underestimate the internal effort required to adopt new core systems, focusing only on the potential long-term benefits without adequately planning for the short-term disruption. Our view is that firms must conduct a thorough cost-benefit analysis that considers not just software license fees but also the crucial costs of retraining staff and redesigning internal workflows. The potential efficiency gains are substantial, but so are the risks of operational friction during a hasty implementation. Evaluating and integrating such transformative technologies is a core part of our business process reengineering services.

According to company statements, Instead’s platform is designed not as a tool for human preparers but as a full replacement for the manual tax preparation workflow. The system uses what the company calls “AI Agents” to execute the entire process, from building digital folders and creating workpapers to preparing returns, resolving diagnostics, and managing e-filing. This end-to-end automation allows a single user to manage the tax processes for hundreds of entities simultaneously, a fundamental departure from the one-to-one workflow of traditional software. The company has explicitly named its targets as the market’s largest incumbents, including CCH Axcess, GoSystem Tax RS, UltraTax CS, Lacerte, ProConnect, and Drake Tax. These platforms, while widely used and feature-rich, are largely built on older architecture that presumes a human is manually preparing each return. Instead is marketing its unified, AI-native system as a way for firms to consolidate their tech stack and eliminate the need for multiple software licenses for different tax and workflow functions. This final approval follows a series of announcements tracking the company’s rapid progress. In a March 2026 release, Instead reported it had secured 67% of all required government approvals. By late April, that figure had climbed to over 99%, culminating in the complete nationwide coverage announced this month. “No company has accomplished these approvals in decades,” said Andrew Argue, CEO and founder of Instead, in a previous statement. “Even if another company started today with hundreds of millions of dollars, it would take them years to get through the regulatory approvals our team has achieved.” With regulatory hurdles cleared, Instead is now shifting its focus to market penetration. The company is actively recruiting beta firms for a product rollout scheduled for later this year and is reportedly targeting users of legacy platforms ahead of their next software renewal cycles. The push is supported by a recent strategic investment from Skylark Partners, positioning the company with the capital to challenge the established market order. Going forward, the industry will be watching for signs of market adoption. The key question is how quickly accounting firms, from solo practitioners to large multi-office operations, will be willing to migrate core tax compliance functions from trusted, long-standing systems to a new AI-driven platform. Early partnership announcements and the performance of the platform within its initial beta firms will be critical indicators of its potential to disrupt the professional tax software landscape.
