Your self assessments made easy...

Usually, income tax is automatically deducted from saving, pensions and wages through processes such as the PAYE scheme.

However, if you are self employed or run your own business you may have to complete a self assessment tax return.

If you need to complete one, you will need to complete it after the end of the tax year, which is April 5th.

There is a deadline for the completion of your self assessment tax return, which is usually the 31st January in the following year.

So, as an example, the deadline for your self assessment tax return for the tax year of 2017-2018 would be January 31st 2019.

Failure to complete and return it by this deadline, as well as any errors, can result in large fines being given to you by HMRC.

If you are not very confident in your accountancy skills, it is recommended that you hire a professional accountant to assist you with this.

  • Your income was more than £1000 from your self employed activities.
  • You earned more than £2500 from renting out properties.
  • Your untaxed income, for example from commission or tips, is more than £2500.
  • Income earned from investments or savings was equal to or greater than £10,000 before tax.

  • Your taxable is over £100,000.
  • If you are earning over £46,351 and are making pension contributions you may need to complete a self assessment so that you can claim back the tax relief that HMRC owes you.
  • You are a trustee of a pension scheme or a trust.
  • If your state pension was your only source of income and was more than your tax free allowance.
  • HMRC sent you a P800 stating that you did not pay enough income tax in the previous year.

If you wish to make voluntary Class 2 National Insurance Contributions to ensure that you qualify for a state pension as well as other benefits you may need to fill out a self assessment tax return.

If you are paid through the PAYE system, you will not have to fill out a self assessment tax return, unless of course, you have earned over £100,000 in that tax year.

Do I need to register for a self-assessment tax return?


If you need to complete and file a self assessment tax return then you will need to register the first time that you do it.

You can register in different ways depending on whether you are in a partnership, not self employed, or self employed.

When you register you will be sent a Unique Taxpayer Reference (UTR) by HMRC.

You need to hold on to this as you will need it when setting up on the government website, and it is looking increasingly likely that in the future all tax returns will have to be submitted electronically.

However, at present you can still submit your self assessment tax returns in paper form.

To set up your self assessment form online you will have to create a new Government Gateway Account.

It is a simple process, and you will receive a letter from HMRC which contains straight forward instructions for you to follow.

Once you have set up your government gateway account then you will receive an activation code through the post, you will need this to finalise the creation of your Government Gateway account.

If you have already submitted a self assessment tax return in the past, you will have to use your old UTR to create you Government Gateway account.

You should check that you are able to access your Government Gateway account before you file your self assessment tax return, to ensure that you are able to file your tax return on time and avoid fines.

Are there deadlines for self-assessment tax returns?


Self assessment tax returns are submitted for tax years, they are not submitted for calendar years, they are also submitted in arrears.

As an example, for the tax year of 2015/2016, which runs from 6 April 2015 to the 5th April 2016, you need to:

  • Register to complete a Self Assessment before 5th October 2017 in the event you have never submitted a tax return before.
  • If you are filing a paper tax return you need to file it with HMRC before 31st October 2017.
  • If you are filing online you will need to file it before midnight 31st of January 2018.
  • All tax owed must be paid in full by midnight 31st of January 2018.

The monthly dates for the deadline remain the same for each year.

In the event that you do not meet these deadlines then it is likely that HMRC will fine you.
