How agentic AI is changing accounting compliance
The deadline for MTD is fast approaching. Discover how agentic AI empowers you to reduce admin and help clients navigate MTD with confidence.
Behind every tax deadline is an ocean of detail.
Your clients see deadlines met, tax bills sorted, books that are tidy, and payroll that runs smoothly.
But the reality is different. You’re managing ever-changing tax laws, keeping up with evolving HMRC guidance, reconciling errors, juggling multiple systems, and handling endless back-and-forth communication. And that’s only scratching the surface.
In this article, we explore how AI is helping to shape and enhance these challenges.
Here’s what we discuss:
The impact of agentic AI on compliance
The way accountants handle compliance is undergoing a fundamental shift.
As new technologies like agentic AI emerge, the manual and repetitive tasks that once defined compliance are being stripped away.
One of the clearest examples of this transformation is Making Tax Digital (MTD). It’s no secret that MTD is reshaping the UK tax landscape, and the next wave is around the corner in April 2026.
While this brings new challenges, this time you’ll have something extra on your side: agentic AI.
Here’s how Georgina Timothy, Director of Product Management for Sage for Accountants, summarises agentic AI for accountants:
MTD is going to be more than a digital filing requirement, it’s a fundamental shift in how tax is reported and how data flows between HMRC, accountants, bookkeepers, and their clients.
By April 2026 sole traders and landlords with a gross qualifying income over £50k must comply and, by 2028, that threshold lowers to £20k, which will bring thousands more into scope.
With this expansion comes quarterly submissions and more frequent data touchpoints, which could leave room for more errors.
Even though this shift may seem like a compliance headache for both you and your clients, it’s also a strategic opportunity for your practice.
As compliance becomes more about reviewing rather than inputting information, agentic AI can step in to transform the process.
MTD will become a reality, but it brings with it an opportunity to simplify and automate.

Why agentic AI matters for MTD
Unlike generic AI, agentic AI won’t just automate tasks. It will adapt, anticipate and support you in real time.
These tools help you to stay compliant, reduce admin, and deliver more value. Here’s how:
- Real-time categorisation: Transactions are tagged correctly at the point of entry, reducing the need for end-of-year clean-up.
- Error detection and correction: AI reviews the submitted data, flags anomalies, and can even suggest or apply corrections.
- Workflow automation: From receipt capture to quarterly submissions, AI can streamline the entire MTD process.
- Client insights: AI provides actionable feedback, helping clients understand their financial position and tax obligations.
Beyond merely digitising tax returns, MTD can also be seen as an opportunity to reshape your relationship with your clients.
MTD isn’t a one-size-fits-all, so you’ll have some clients that simply rely on you to file their final return and others who want you to handle everything end-to-end.
Agentic AI adapts to each of these scenarios, helping you to manage your workload no matter how your clients prefer to work.
