Self Assessment and tax returns

We prepare your return from your records and file it with HMRC. You pay one fixed fee, agreed before we start.

Do you need to send a return?

HMRC uses Self Assessment to collect Income Tax on income that is not taxed before you receive it. These are the gov.uk criteria.

Still not sure? gov.uk has a short tool that gives you an answer.

  3. The fee is fixed once the services are agreed. You know what you will pay.

Questions people ask

Answers drawn from gov.uk, with the link beside each one.

Do I need to send a return if I am employed?

Not always. Tax is usually taken from wages and pensions before you are paid. gov.uk says people and businesses with other income must report it in a return, and you must send one if HMRC asks you to.

Check if you need to send a return on gov.uk

What happens if I send my return late?

HMRC charges a penalty. gov.uk lists an initial £100, then £10 a day after 3 months, up to a maximum of £900 for the daily amounts. Paying late brings a separate penalty, and other penalties can apply.

Penalties on gov.uk

Can I file before January?

Yes. gov.uk says you can send your return any time after 5 April. Filing early lets you find out what you owe and budget for it. The deadline to pay is still 31 January.

When to send your return on gov.uk

I think I no longer need to send a return. What do I do?

Tell HMRC as soon as you can. gov.uk says HMRC needs time to review your request before the 31 January deadline, and you may get a penalty if you tell it too late.

Which records do I need to keep?

gov.uk says to keep records, such as bank statements or receipts, so you can fill in the return correctly. Send us what you have and we will tell you what is missing.
