HMRC contacting trusts over tax return errors

24 September 2026

HMRC is writing to trustees who ticked box 8.15 on the Trust and Estate Tax Return, suggesting some trusts may actually be accumulation or discretionary trusts taxed at 39.35% and 45%. Trustees must respond by 2 November 2026. Here is what HMRC contacting trusts over tax return errors means for you.

HMRC contacting trusts over tax return errors

Trustees across the UK are receiving unexpected letters. HMRC is contacting trusts over tax return errors linked to the type of trust reported. Therefore, if a letter lands on your desk, act promptly rather than ignoring it.

 

What has prompted the campaign

The latest compliance campaign focuses on one specific box. HMRC has reviewed returns where box 8.15 was ticked. That tick confirms the trust is not an accumulation or discretionary trust.

However, HMRC’s records suggest otherwise in some cases. Consequently, those trusts may have paid tax at the wrong rates.

Why the trust type matters

Trust classification directly affects the Income Tax rates applied. Accumulation and discretionary trusts generally pay special rates:

  • 39.35% on dividend-type income
  • 45% on other income

By contrast, many other trusts pay lower rates. Nevertheless, some discretionary trusts remain exempt from the special trust rates. As a result, the position is not always straightforward.

How trustees should respond

Do not leave the letter unanswered. Instead, review each relevant tax return carefully. Then respond to HMRC by 2 November 2026.

Your next step depends on what you find:

  • If the returns are correct, simply tell HMRC.
  • If additional tax is due for 2024-25, amend the return and pay the tax.
  • If earlier years are affected, you may need to make a voluntary disclosure.

Interest may also apply. Furthermore, HMRC may charge a penalty depending on the circumstances.

Check your Trust Registration Service details

Meanwhile, take the opportunity to review your wider compliance. Trustees must keep information on the Trust Registration Service accurate. In particular, record any changes to beneficiaries promptly. Otherwise, further problems can easily arise.
