Preparing Your Accounting Firm for MTD ITSA: Key Dates & Strategies to Follow

When was the last time a major tax deadline came and went without a mad rush? If you’re an accounting firm owner or partner in the UK, you know that’s a rare sight. The transition to Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) might feel like just another task on your list—but it’s more than that.

The government’s decision to push back the deadlines to 2026 and 2027 offers some breathing room, but let’s be honest—delays are not an excuse to postpone preparation.

Here’s why now is the perfect time to start gearing up and how your firm can not only meet the deadlines but thrive through this transition.

Why Prepare Now?

1. Avoid the Eleventh-Hour Panic

We’ve all seen how last-minute tax prep stresses clients and staff alike. Preparing now means smoother transitions and fewer late nights down the line.

2. Position Your Firm as a Leader

Clients expect their accountants to stay ahead of tax law changes. By preparing early, you establish your firm as a trusted expert in navigating MTD ITSA.

3. Gain Operational Efficiency

MTD ITSA requires a digital-first approach. Investing in the right tools and processes now will help you reduce manual work, improve accuracy, and save time.

The Challenges

1. Client Resistance to Change

Let’s face it—some clients will resist anything new, especially if it involves technology.

Solution: Break the process into manageable steps. Educate clients on the benefits of MTD, like real-time tax management and fewer surprises at the year-end.

2. Digital Transformation Overload

Switching to MTD-compatible software can feel daunting for firms already stretched thin.

Solution: Start small. Assess your current systems and identify gaps. Consider outsourcing certain tasks to free up your team’s bandwidth.

3. Training Your Team

MTD ITSA compliance requires staff to be well-versed in digital tools and processes.

Solution: Invest in regular training. Partner with tech providers who offer easy-to-follow tutorials.

Strategies to Prepare Your Firm

1. Audit Your Client List

Segment clients based on their income thresholds to identify who will need to transition in 2026 and 2027. This helps prioritise your efforts.

2. Embrace the Right Technology

Adopt MTD-compatible software that integrates seamlessly with your existing systems. Integrate your software tools and look for platforms offering real-time reporting and automation.

3. Educate Your Clients

Host webinars or share guides that simplify the MTD ITSA process. Clients who understand the benefits are more likely to comply without resistance.

4. Outsource Where Needed

Outsourcing routine tasks like data entry or tax and VAT prep allows your team to focus on higher-value activities like MTD ITSA planning and client communication.
