Struggling with a Self-Assessment Penalty? We Can Help You Appeal It

Received a penalty for a late or incorrect tax return? You’re not alone — but the good news is that you may not have to pay it. At Audit Consulting Group, we specialise in self assessment penalty appeal services, helping individuals across the UK fight unfair or excessive HMRC fines.

Whether it’s a late filing penalty, incorrect return, or any issue tied to your tax return submission, we know how to manage the appeals process and get results.

What Is a Self Assessment Penalty?

HMRC can charge penalties if:

  • You miss the Self Assessment deadline (31 January)
  • Your tax return has errors
  • You fail to pay tax on time
  • You don’t register for Self Assessment when required

Penalties can include:

  • £100 for late filing (even if no tax is owed)
  • Daily penalties after 3 months
  • Interest and surcharges on unpaid tax

If you’ve received a penalty you believe is unfair or incorrect, we’ll help you appeal a self assessment penalty and potentially reduce or cancel the charges.

Grounds to Appeal Against Self Assessment Penalties

You can appeal self assessment penalties if you had a reasonable excuse, such as:

  • Illness or hospitalisation
  • Bereavement
  • System errors when submitting
  • Postal delays
  • Natural disasters
  • HMRC errors or wrong advice

If your circumstances prevented you from filing on time or accurately, you may be able to appeal against self assessment penalty charges.
