Tax advisers must register with HMRC and satisfy minimum standards

It won’t have escaped the attention of accountancy firms and tax advisers across the land that from 1 April 2026, HMRC will require tax advisers to register and meet minimum standards.

With the registration deadline set for 1 April 2026, firms have less than five months to ensure they are fully compliant. This is not just a bureaucratic formality – HMRC is raising the bar to ensure that only qualified, competent advisers can act on behalf of clients.

The change will affect virtually every accountancy and tax firm that interacts with HMRC on behalf of clients. That includes filing tax returns, representing clients in enquiries, completing forms, or giving advice that involves HMRC reporting. Firms that fail to act now risk being left unprepared, potentially losing the ability to represent clients or facing enforcement action.

Under the new rules, every firm must:

• Register each adviser with HMRC in accordance with the new requirements.
• Demonstrate compliance with minimum standards, including professional qualifications, ongoing competence, and adherence to HMRC guidance.
• Implement robust internal procedures to ensure all advisers continue to meet these standards.

Time is of the essence

The transition period offered by HMRC is short, and firms that wait until the last minute will face significant administrative pressure. Now is the moment to take proactive steps, assess current systems, and close any gaps in compliance.

How to apply for registration

Despite there being no vehicle in place yet to register, immediate action is essential. With less than five months until 1 April 2026, there’s no time to delay. Firms that start preparing today will not only meet HMRC’s requirements but will also gain a competitive advantage by demonstrating to clients that they are registered, qualified, and ready for the future.

So our advice would be to have the go-live date of 1 April 2026 highlighted in diaries.  Monitor HMRC news for any legislation being enacted and for HMRC issuing the official registration documents. These are likely to appear in the first couple of months of 2026 and will signal the next steps for firms and advisers.

In the meantime, businesses and individuals should begin assessing their activities to determine whether any of the services they provide could classify them as a tax adviser particularly if they interact with HMRC on behalf of others. Early consideration now will make the registration process smoother and reduce the risk of last‑minute complications.

Exceptions to HMRC Registration

Not all tax advisers are required to register with HMRC. According to Section 3, registration is not required if the adviser’s work is limited to any of the following:

• Acting as an employee for an organisation and interacting with HMRC solely in the course of that organisation’s business.
• Providing payroll software or other tax/accounting software, without offering personal tax advice.
• Handling customs-related matters, including excise duties or import VAT.
• Acting as a VAT representative only.
• Interacting with HMRC on behalf of other members of the same corporate group.
• Appealing to a court or tribunal rather than engaging directly with HMRC on client matters.
