Personal Tax & Self Assessment


If you are self-employed or have earnings or profits from selling shares or property then you need to submit a self assessment tax return. Self Assessment is how HMRC collect tax from people and businesses with these types of income.

Income Tax is generally taken from your wages or pension income (if you are employed) before it reaches you, but some income isn’t taxed at source. This means that even if you are employed you may need to submit a self assessment tax return. 

For example, Company Directors or High Earners claiming Child Benefit, or earning money from renting a property or having a second business or income.

Do I need to submit a tax return?

You might need to complete and submit a tax return if you:

  • are self employed or a partner in a partnership
  • are a company director
  • have large amounts of savings or investment income
  • have untaxed savings or investment income
  • own land or property that is rented out
  • have income from overseas
  • your household receives Child Benefit and you have income in excess of £50,000
  • have sold or given an asset away (such as a holiday home or some shares)
  • haveve lived or worked abroad or aren’t domiciled (live) in the UK

Let us complete your tax return

Our tax experts have access to the most current software and systems to complete your tax return as efficiently as possible.

We are also able to review your income with you and calculate your likely tax liability at any time. This enables us to help you calculate your tax liability at the year-end and file your tax return.

If you’ve never submitted a return before, you will first need to register for Self Assessment on the GOV.UK website.

Once you have registered, you will be sent your Unique Taxpayer Reference (UTR). You need to let us know this so we can file your return.

Doing your own tax return

If you want to submit your Self Assessment form online, you need to set up a Government Gateway account.

To do this, follow the instructions in the letter containing your UTR. If you have submitted Self Assessment tax returns before, you will need your old UTR to register and set up the account.

Once you’ve set up the account you will get an activation code in the post, which you need to complete the set-up of your Gateway account.

It’s best to make sure you can access your Gateway account before you try and submit your Self Assessment, just in case you can’t log in.

What are the Self Assessment deadlines?

You submit tax returns for tax years, not calendar years, and you do this in arrears. The standard tax year runs from 6th April one year to 5th April the next.

For untaxed income earned during the 2021-22 tax year, the online deadline for filing your Self Assessment tax return and paying your bill is midnight 31 January 2023.

Self Assessment deadlines in 2022

Before the next online tax return deadline comes around, there are several other Self Assessment dates in 2022 to bear in mind. It’s unlikely that all of them will be relevant to you. Please make sure you understand which ones apply so that you don’t miss any important deadlines.

  • 31 July 2022 is the deadline for making your second ‘payment on account’ instalment to HMRC. This will only apply to you if you were self-employed during the tax year 2020/21 ,and you owed tax of over £1,000 when you submitted your tax return for this period.
  • 5 October 2022 is the deadline for telling HMRC that you’re self-employed so that they’re aware you need to complete a tax return next year. If you’re already registered as self-employed, there’s no need to do this again.
  • 31 October 2022 is the Self Assessment deadline for the tax year 2021/22 if you want to file a paper return rather than filing online. However, most taxpayers find it easier to file their tax return online – and under the government’s Making Tax Digital plans, eventually paper filing may not be an option.
  • 30 December 2022 is the deadline for filing your online tax return if you want the tax owed to be collected through PAYE via your tax code. This is only an option if you have some income that’s already taxed through PAYE (e.g. if you’re employed as well as self-employed), and if your Self Assessment tax bill for 2021-22 is below £3,000. 

Self-employed income earned after 5 April 2021

If you continue earning untaxed income from 6 April 2021, this will fall into the tax year 2021-22, which ends on 5 April 2022.

The deadline for filing a 2021-22 Self Assessment tax return will be midnight on 31 January 2023. It’s a good idea to keep an eye on Making Tax Digital announcements in case there are any updates.

If you fail to meet one or more of these deadlines, you might be charged a penalty.
