Self Assessment tax returns

Self Assessment After an HMRC Notice to File

If you have received an HMRC notice to file a Self Assessment tax return, you must submit a return even if you did not expect to. This service helps you understand what HMRC needs, gather the right figures, and file an accurate return on time, with clear guidance in plain English.

More information

What this service covers

You get practical, end to end support to respond to the notice and complete the return correctly.

  • Confirming why you have been issued a notice to file and what year it applies to
  • Checking what income and gains need to be reported (employment, self employed, property, dividends, savings, crypto and more)
  • Claiming allowable expenses and reliefs where applicable
  • Calculating your tax and National Insurance position and explaining the result
  • Submitting the return to HMRC and confirming successful filing
  • Advising on payment dates, payments on account, and what to do next

When this is the right service

This is most useful if you are time poor, unsure what to include, or worried about getting it wrong. It is a good fit if:

  • you have never filed Self Assessment before
  • you stopped trading but HMRC still issued a notice
  • you have multiple income sources and need clarity
  • you are behind and want a clean, compliant plan forward

How the process works

  1. We confirm the tax year(s) and the HMRC requirement to file.
  2. We send a clear list of the information needed and help you fill any gaps.
  3. We prepare the return, talk you through the figures, then submit once you approve.
  4. You receive confirmation of filing and a simple summary of what to pay and when.

After filing: staying on top of future returns

If HMRC will continue to expect a return, we can help you stay organised through the year, keep records in order, and plan ahead for tax so there are no surprises. If you no longer need Self Assessment, we can advise on next steps to reduce the risk of future notices.

Frequently Asked Questions

Do I have to file if I received a notice to file but had little or no income?
Usually yes. A notice to file is a legal requirement, even if you owe no tax. We will confirm what needs reporting and help you submit correctly to avoid penalties.
What happens if I miss the Self Assessment deadline after getting a notice to file?
HMRC can charge automatic late filing penalties and interest, even if you owe no tax. If you are already late, we focus on filing quickly and explaining what penalties may apply.
Can you help if I do not have all my records yet?
Yes. We will tell you exactly what is needed and help you obtain missing figures, for example P60s, P45s, bank interest, dividends, or expense evidence. Where estimates are not appropriate, we will explain the options.
Will you tell me what I can claim as allowable expenses?
Yes. We review your situation and apply the rules to identify allowable expenses and reliefs that are relevant to you. We also explain what not to claim so you stay compliant.
Can you deal with more than one tax year if HMRC has asked for it?
Yes. We can prepare multiple outstanding returns and help you understand the total tax position and payment timetable. If needed, we can also discuss practical steps to get back on track going forward.
