In a profession known for its measured approach to change, agentic AI is emerging as a transformative force for accountants, redefining the nature of daily work and opening the door to more meaningful (and profitable) relationships with clients. But what is agentic AI, and how is it transforming the accounting profession?

Agentic AI leverages generative AI and large language models to autonomously plan, reason, and execute multi-step processes. While advanced tax technology and automation are nothing new for most accounting firms, the introduction of agentic AI is redefining what classifies as a “mundane” task.

For years, automation has eliminated the need for tax professionals to spend their days steeped in manual data entry, searching for blank fields or numbers that don’t add up. With agentic AI, accountants can automate complex pieces of the tax return process. This shift transforms the value proposition of accounting firms, making what was once the centerpiece of a firm’s offering a byproduct of a deeper client-focused relationship built on strategic planning and personalized advisory services.

Agentic AI presents an opportunity to significantly elevate the role of accountants from once-a-year tax preparers to year-round tax consultants. Here’s how.

Agentic AI in action: Practical use cases for accountants

Unlike traditional AI, which is typically reactive and limited to predefined tasks (such as rule-based automation or predictive analytics), agentic AI can dynamically adapt to changing circumstances, proactively seek information, and refine its outputs without constant human intervention. By operating autonomously, agentic AI can make decisions and take actions based on goals, constraints, and real-world feedback.

So, what are the practical use cases?

Agentic AI can automate tax compliance and reporting by continuously monitoring tax law changes, analyzing financial data, and proactively identifying potential compliance risks. It can autonomously gather and categorize transaction data, apply accurate tax treatments, and help users throughout the tax filing process  — alerting you when anomalies or strategic decisions require experienced input.
