If you’re self-employed, run a business, or file your own tax return, chances are you rely on a trusted accountant or adviser to keep your finances in order. But from April 2026, that relationship could face serious disruption — especially if your accountant isn’t ready for new rules being introduced by HMRC.
What’s Changing?
From 1 April 2026, every accountant and tax adviser who deals with HMRC on behalf of clients must register with HMRC and meet new professional standards.
If they’re not registered, they won’t be legally allowed to:
- File your tax returns
- Give you tax advice
- Speak to HMRC on your behalf
- Help with tax planning or compliance
No registration = no service. It’s that simple.
Why This Affects You Directly
Although the changes are aimed at improving quality and accountability in the tax advice industry, they could have serious consequences for individuals and businesses who unknowingly rely on advisers who aren’t prepared.
If your accountant isn’t ready by April 2026, you could be left scrambling — without warning — to find someone who is. And let’s be honest: the last thing you need during a busy tax period is to deal with sudden service disruption or compliance issues.
This is why it’s so important to check in now. Don’t assume your accountant is already taking care of it. Ask the questions, understand their plan, and make sure you’re not caught off guard.
What to Watch Out For
Not all advisers will be up to the task. Some may miss the deadline due to disorganisation, lack of qualifications, or simply being unaware of what’s required. Others may not meet the new minimum standards set by HMRC. Ask yourself:
- Have they mentioned the 2026 HMRC changes to you yet?
- Are they well-organised and responsive?
- Do they explain things clearly, or leave you in the dark?
- Do they seem overwhelmed by existing rules?
If they haven’t brought this up by now — or seem unsure about it — that’s a red flag.
What a Good Accounting Firm is Doing Now
Professional, forward-thinking firms are already taking action. They’re reviewing HMRC’s registration process, updating their internal systems, making sure staff are trained and qualified, and proactively communicating with clients to ensure there are no surprises down the line.
At Jermyn & Co, we see this change not as a challenge — but as an opportunity to reinforce the quality and integrity of our service. We are authorised and regulated by the ICAEW (Institute of Chartered Accountants in England and Wales) — an organisation that represents the highest professional and ethical standards in the accounting industry. This not only reflects our ongoing commitment to compliance and excellence, but also gives our clients peace of mind knowing their affairs are in trusted hands. Meanwhile, we are an ICAEW-approved training employer, our staff are trained and qualified, and proactively communicating with clients to ensure there are no surprises down the line.
What You Should Do Now
If you’re happy with your current accountant, now’s the time to have a quick conversation. Ask how they’re preparing for the 2026 changes and whether they’ll be registered with HMRC ahead of the deadline. A simple check-in now could save you a lot of stress later.
But if you’re unsure about the quality or reliability of your current support — or if you’ve outgrown them — this is the perfect moment to consider working with a firm that’s already one step ahead.
With deadlines approaching and demand for qualified accountants likely to surge in 2026, finding the right partner early gives you breathing space, better service, and peace of mind.
Why You Shouldn’t Wait
Leaving it until 2026 could mean:
- Getting stuck without support when you need it most
- Facing delays, missed deadlines, or penalties
- Rushing into a last-minute replacement
- Paying more as demand for good accountants spikes
