HMRC Penalty Appeal Help: When an Accountant Can Help
Do not ignore an HMRC penalty notice
An HMRC penalty notice should be checked promptly. It may relate to a late return, late payment, an incorrect figure or missing information. The notice should tell you what the penalty is for, how much it is and what to do if you disagree.
First steps when a penalty arrives
- Read the notice and note the response or payment deadline.
- Check which tax, return and period the penalty relates to.
- Confirm whether the return was submitted and payment was made.
- Gather evidence such as medical records, correspondence, bank evidence or proof of a technical problem.
- Do not assume the penalty disappears because the return has now been filed.
What is a reasonable excuse?
HMRC may accept a reasonable excuse where an unexpected or unusual event prevented you from meeting a deadline and you acted without unreasonable delay afterwards. Examples can include serious illness, bereavement, fire or flood, or a major service failure. The facts and evidence matter, and not every explanation is accepted.
How an accountant can help
We can review the notice, check the underlying return, identify missing information and help prepare a clear response. Where an appeal is appropriate, the explanation should set out what happened, why it affected the deadline, what you did next and why the request is being made within the relevant time limit.
An appeal is not a substitute for completing the return or paying undisputed tax. Those steps should usually happen while the position is being reviewed.
Preventing repeat penalties
- Use a calendar with filing and payment dates.
- Keep HMRC login details and authorisations up to date.
- Keep digital and paper evidence in one record system.
- Set an earlier internal deadline for preparing figures.
- Ask for help before a deadline if your records are incomplete.

Frequently asked questions
Can an accountant cancel an HMRC penalty?
No accountant can guarantee an outcome. We can assess the facts, explain the options and help present an accurate appeal where there are valid grounds.
Should I pay the penalty while appealing?
Check the notice and your specific tax position. The payment rules can differ, so obtain advice promptly rather than allowing a deadline to pass.
Can you deal with HMRC for me?
With the appropriate authorisation, an accountant can communicate with HMRC about the relevant tax affairs and help you respond to information requests.
