HMRC guidance / practice
According to HMRC guidance, the contact route depends on your specific situation:
- If you file under Self Assessment: https://www.gov.uk/government/organisations/hm-revenue-customs/contact/self-assessment
- If you do not file under Self Assessment (e.g. individuals, pensioners, employees): https://www.gov.uk/government/organisations/hm-revenue-customs/contact/income-tax-enquiries-for-individuals-pensioners-and-employees
- If you are self-employed: https://www.gov.uk/government/organisations/hm-revenue-customs/contact/income-tax-enquiries-for-self-employed
- If you are a tax agent acting on behalf of clients: https://www.gov.uk/guidance/dedicated-helplines-and-contacts-for-authorised-agents
More general guidance is also available on GOV.UK, which provides information on how to contact HMRC across a range of tax matters.

Just as with other reasonable excuses, you must consider: the person`s own experience or relevant attributes, their situation at the relevant time, and any relevant external factors to decide whether they have a reasonable excuse for being unaware of or misunderstanding their obligations. Some people will have more contact with HMRC or other professionals who can advise them on tax and therefore will be more informed about tax matters than others. HMRC provide guidance and information on Gov.uk.
Individuals must tell HMRC within 60 days of coming to know of an event by reason of which ‘front-end’ income tax relief should be withdrawn. Penalties under TMA70/S98 may be charged where they do not.
