Help & Support

HMRC offers web guidance, webinars, and helplines — get help early if you are unsure.

What it is

HMRC publishes detailed guidance on GOV.UK, runs webinars for MTD, and provides helplines for Self Assessment and VAT. Complex cases may need professional advice from a qualified accountant.

Who it applies to

Everyone in MTD — especially when starting out or changing business structure.

What you need to do

  • Read the relevant GOV.UK collection for your situation.
  • Attend HMRC webinars for MTD for Income Tax.
  • Contact HMRC if you cannot meet a deadline — do not ignore letters.

Key points

  • SelfSubmit helps organise records and submissions — it does not replace HMRC guidance or professional advice.
  • Always verify rule changes on GOV.UK.
