Disagree with a tax decision
3. Appeal against a penalty
You can appeal to HM Revenue and Customs (HMRC) against a penalty for:
- sending in your tax return late
- paying tax late
- not paying enough tax
- failing to keep adequate records
Your penalty will be cancelled or amended if you have a reasonable excuse.
How to appeal to HMRC
If HMRC sends you a penalty letter by post, use the appeal form that comes with it or follow the instructions on the letter.
For Self Assessment, PAYE, VAT and Corporation Tax, there are extra documents you can use or alternative ways to appeal.
If you’re appealing a Self Assessment penalty
You can appeal a late filing penalty online for a 2015 to 2016 tax return. You’ll need to set up a Government Gateway account if you don’t have one.
- the date the penalty was issued
- the date you filed your Self Assessment tax return (if you’ve filed it)
- details of your reasonable excuse for late filing
If you’re appealing a PAYE penalty
You can now appeal online using HMRC’s PAYE for employers service. Once you’ve logged in, select ‘Appeal a penalty’. You’ll get an immediate acknowledgment when you submit your appeal.
If you filed a late VAT or Corporation Tax return
You can also use these specific forms for:
- VAT if you had a reasonable excuse for filing late
- Corporation Tax if you filed late because of computer problems
If you don’t have an appeal form
You can send a signed letter to HMRC instead. Your letter must include:
- your name
- your reference number, for example your Self Assessment Unique Taxpayer Reference (UTR) or VAT registration number
- a full explanation of why your return or payment was late, including dates
If you couldn’t file or pay because of computer problems, you should include the date you tried to file or pay online with details of any system error message.
Send your claim to the HMRC office related to your return.
You must appeal within 30 days of the date of the penalty notice. If you appeal later, HMRC will look at the information you give them and decide if they’ll consider your appeal.
If you disagree with HMRC’s response
You can ask for a review to be carried out by an HMRC officer who wasn’t previously involved, or you can ask the tax tribunal to hear your appeal.
