What is Self-Assessment?

Your Self-Assessment is a standard tax return form. As a business owner, you’ll need to send a report of your annual earnings to HMRC. Your Self-Assessment tax return should also include the sources of your earnings.

It’s called Self-Assessment because it is your responsibility to work out how much tax you have to pay.

If you’re going to file your self-assessment tax return online, this will need to be done by 31 January after the end of the tax year.

If you’re not filing your return online, it needs to be done by 31 October after the end of the tax year.

The tax year runs from 6 April to 5 April of the following year.

Our self assessment service includes preparation of your return and a calculation of what tax you owe. We also ensure you have claimed any expenses that you are entitled to and submit your return for you.
