## What’s Changing for Tax Advisers
From **1 April 2026**, HMRC will enforce stronger rules under the measure “Tackling tax adviser facilitated non-compliance”. Tax advisers who *deliberately* help clients evade taxes will face tougher penalties, including new powers for HMRC to:
- issue **file access notices** with senior HMRC officer approval (no longer tribunal-only) to inspect adviser files if non-compliance is suspected ([gov.uk](https://www.gov.uk/government/publications/tackling-tax-adviser-facilitated-non-compliance/tackling-tax-adviser-facilitated-non-compliance-by-enhancing-hmrcs-powers?utm_source=openai));
- impose penalties for providing **inaccurate information** and sanction adviser misconduct based on the scale of tax loss ([gov.uk](https://www.gov.uk/government/publications/tackling-tax-adviser-facilitated-non-compliance/tackling-tax-adviser-facilitated-non-compliance-by-enhancing-hmrcs-powers?utm_source=openai));
- publicly name advisers who are sanctioned for serious breach ([gov.uk](https://www.gov.uk/government/publications/tackling-tax-adviser-facilitated-non-compliance/tackling-tax-adviser-facilitated-non-compliance-by-enhancing-hmrcs-powers?utm_source=openai)).
Also, from **May 2026**, all tax advisers who interact with HMRC must **register** and meet minimum professional standards, including anti-money laundering supervision etc. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-138/issue-138-of-agent-update?utm_source=openai)).
## Why Businesses and Individuals Should Care
- If you rely on a tax adviser, ensure they are properly registered by **May 2026**.
- Be wary of advice that seems to skirt close to non-compliance — dishonest schemes could now expose both adviser and client to published sanctions and penalties.
- Businesses using advisers should check advisers’ credentials and whether they possess AML registration status etc.
## Practical Steps to Adapt Now
1. **Due diligence**: Ask your adviser for their registration number once the new register is live; check their record.
2. **Documentation**: Keep detailed files of advice, correspondence and reasoning, in case HMRC later requests evidence.
3. **Audit review**: Periodically review past advice and any areas where tax treatment might have relied on aggressive or borderline interpretations.
4. **Seek second opinions**: Especially for complex tax structuring or cross-border arrangements.
## Example Scenario
Imagine you own a small UK business and your adviser suggests a scheme to allocate some income offshore to reduce UK tax liability. Under old rules, this might have been accepted if technically legal. Under new rules, if the scheme is judged to *facilitate non-compliance*, HMRC can now demand access to your adviser’s files, impose penalties on both client/adviser, and possibly publish the adviser’s name. You could lose the tax benefit and get hit with fines.
## Bottom Line
These reforms represent a clear shift: HMRC aims to reduce the tax gap by putting greater legal and reputational risks on advisers who do not uphold compliance. Clients must become more proactive, asking questions, verifying credentials and ensuring their adviser operates with transparency and legal risk in mind.
