What is self assessment?
Self assessment is HMRC’s way of finding out how much income tax and National Insurance a self-employed need to pay.
You might need to complete a Self Assessment return even if you are not self-employed.
For instance, if you earn money from renting out a property, or have significant income from investments, savings and dividends.
Employees automatically have their income tax deducted from their income through the PAYE system, but this doesn’t happen for self-employed people.
Self assessment involves completing a tax return (or Form SA100) and is usually done online, though it is still possible to file in the old fashioned way with a paper form. Submission deadlines are different for paper and online versions.
Circa 11.7 million people were required to file their 2018-19 tax returns by 23.59 on 31 January 2020. More than 700,000 submitted the tax returns on 31 January 2020, the peak hour for the filing was between 16:00 to 16:59 when 56,969 tax returns were filed.
Last year, 26,562 registered self-employed people completed their tax returns from 23:00 to 23:59 on the Friday 31 January 2020.
Who needs to complete the self assessment tax return?
A self assessment tax return must be completed by any individual paid outside of the PAYE scheme or has received additional untaxed income on top of their PAYE.
In most cases, full-time employees pay tax and National Insurance before receiving their monthly salary and will not be required to pay additional tax.
This means they would not be required to file an annual tax return.
You will generally be required to submit a tax return if any of the following applies:
- You are a director of a company
- If you have received income from land or property in the UK
- If you have capital gains tax to pay
- If you have received taxable foreign income in excess of £300 a year
- If you have received income from a trust or settlement
- If your annual income exceeds £100,000
- If you receive £10,000 or more from taxed savings and investments
- If you are higher rate taxpayer and receive £2,500 or more from untaxed savings and investments
- If your income is over £50,000 and you or your partner have received child benefit payments
Steps to fill in your self assessment tax return
Step 1: Register for the self assessment
If you are filing the self-assessment tax return for the first time, you will need to first register with the HMRC.
You can register online using HMRC’s website.
Whether you are self-employed, registering a partnership, or not self-employed, the process will vary so choose an option that applies to you carefully.
Step 2: Get your UTR number and set up a government gateway account.
As soon as you register for the self-assessment, you will automatically be issued a Unique tax reference (UTR) number.
If you cannot find it, you can also call HMRC on 0300 200 3310 to ask about the UTR number.
You’ll require some information on hand for security questions, such as your personal details and National Insurance number.
If you want to submit the self assessment tax return online, you will need to set up a government gateway account.
You can set up your government gateway account by following the letter’s instructions containing your UTR number.
Once you have set-up the account, you will get the activation code in the mail, that will complete the set-up of the gateway account.
This entire process could take up to 20 days, so make sure to not leave it until the last minute.
Step 3: Make sure that you have correct information gathered
Prior to starting out, you will need to make sure you have the following information on hand:
- Unique Taxpayer Reference (UTR)
- National Insurance number
- Records of expenses relating to self-employment
- A total of any property income you’ve received
- Certificates detailing interest you have received from your bank
- Any overseas income you received
- Any income you have received as part of a partnership (one partner should also file a tax return for the partnership as the whole)
- Information about any dividends you received
- All taxable benefits you have received from the state
- All capital gains you have received by disposing of assets
- Details about any Gift Aid you have received (you can claim tax back for this – visit GOV.UK for more information
- Details of pension contributions, as you may be able to claim some of this money back – visit GOV.UK for more information
- Details of any tax payments you have already made this year (known as payments on account – visit GOV.UK for more information
- Details of the income earned from employment which may include your P60, your P11D form, P45 if you left during the tax year, detailing any benefits and expenses you have received that weren’t processed through a payroll system, or your P2 coding notice, which explains your PAYE tax code.
Step 4: Prepare the tax return
Once you have all the relevant income information from step 4 above, start completing self assessment tax return. You will see a page similar to one below. Start completing the sections one after another.
Fill out your self-assessment tax return slowly and carefully.
You can always save it and come back to it if you are doing it online, so there’s no need to hurry.
Step 5: Submit the tax return
Once you have filled in the above information, your tax liability will be automatically computed.
Also, check back through all the information you have entered before you press Submit
You can edit every detail at any point before submitting.
You will get a confirmation and code number once you submit.
It is best to keep a note of this number as a reference for the future.
Step 6: Pay the tax bill
After you submit your tax return, it is time to pay the amount you owe. It is vital that you pay tax before the deadline. Late payments usually attract interest and penalties.
You can pay a tax bill by debit card, bank transfer, Bacs, direct debit.

Step 7: Keep the record of your tax return
It is always good to keep the record of your tax returns.

If you are a landlord or self-employed, you should keep the records for at least five years and 10 months.
