What Happens If You File Your Self Assessment Late

Missing the 31 January deadline can carry serious consequences – it’s not just about paying late, but also being penalised. Here’s what you need to know:

  1. Late filing penalties
    • If your self assessment is late to submit, HMRC charges a fixed £100 penalty straight away.
    • After 3 months of delay, a further £10 per day charge kicks in – up to a maximum of £900.
    • At 6 months late, there’s an extra penalty of 5% of the tax due (or £300, whichever is higher).
    • After 12 months, another 5% (or £300) is charged again.
  2. Late payment charges
    • If you pay your Self Assessment tax late, HMRC adds a penalty of 5% of the outstanding tax at three points: 30 days, 6 months, and 12 months after the due date.
    • On top of that, you’ll also pay interest on the unpaid amount.
  3. What’s the fine / penalty?
    • The “fine” for late self assessment really depends on how late you are: from the fixed £100 to daily penalties, to significant percentage-based charges.
    • You can estimate your penalties using HMRC’s online tool to get an idea of what you owe.
  4. Can you appeal?
    • Yes, if you have a reasonable excuse (e.g. illness, bereavement) for filing or paying late, you can appeal the penalty.
    • But be ready: HMRC will ask for evidence, and if your appeal is rejected, you’ll need to pay interest on both the tax and the penalty from the original due dates.
