This is the tax return to which the penalty relates. If you have already filed this tax return you need to check whether or not you filed it by the deadline. If you have not yet filed the return you should do so as soon as possible to minimise any further penalties being charged. If you don't need to complete a tax return contact HMRC.
The due date for filing the tax return depends on whether it is a paper return or an online return. Check the filing deadline on our section When do I have to send my tax return to HMRC?. If you did file the return on time you must contact HMRC and explain this and try to find out why they have issued a penalty notice.
This is the amount of the fine. Check it is correct. If you think it is incorrect, contact HMRC and explain why.
