Personal details

Below are the personal details you will need before starting the process of filing a Self Assessment tax return if you haven’t filed one.

1. Unique Taxpayer Reference (UTR)

When you first register for a Self-Assessment tax return, you will receive a 10-digit number from HMRC, which is known as your Unique Taxpayer Reference (UTR) number. Keep it with you, as it is essential for your identification as a taxpayer, and you need it for future tax returns.

2. Government Gateway User ID

When you register for a self-assessment tax return, you will also receive a 12-digit number, your user ID. This number acts as a username to access your online account.

3. Activation code (only for your first Self Assessment)

If you register for Self Assessment for the first time, you should receive an activation code after creating your HMRC tax account using your user ID. This code is essential for accessing your tax account and completing the registration process for Self Assessment.

4. National Insurance number

The National insurance number is used to identify any National Insurance Contributions (NICs) and taxes against your name.

Income and expenses

There are a number of specific categories that you are presented with and which you need to allocate your income to:

1. Employment income

If you are employed, you need to collect your P60 from your employer, which will provide information on your earnings and tax deductions for the tax year. Also, you need to use the supplementary page SA102 form to record your employment income on your SA100 tax return.

2. Self-employment income

If your turnover was below the VAT threshold for the tax year, you should use supplementary pages SA103S to record your self-employment income; if it was above the VAT threshold, you should use supplementary pages SA103F to record self-employment income on your SA100 tax return.

3. Saving income

Income from savings includes interest earned from savings accounts, investments, etc. Gather this information together and keep this handy, as it is essential for your tax return.

4. Income from property

5. Income from trust

Beneficiaries of a trust declare their income received from the trusts during tax returns.

6. Overseas Income

If you have income from foreign sources, such as rental income, you may need to showcase it on the supplementary pages SA106 on your SA100 tax return.

7. Income from partnership business

If you are one of the partners of a partnership, utilise the supplementary pages SA104S and SA104F to document a concise or full partnership income on your SA100 Tax Return.

Allowable tax deductions:

In a similar way, there are specific categories for declaring expenses which can be offset against any tax you have to pay, so you need to gather all of the relevant information together before you start the Self Assessment process:

1. Rental property expenses

You can claim allowable expenses related to your rental property, including property maintenance, letting agent fees, landlord insurance, travelling expenses, and mortgage interests.

    3. Non-resident landlord scheme

    If you are not a resident of the UK but earn rental income from your properties in the country, you must declare your tax liability as a non-resident landlord on your SA109 supplementary pages on your SA100 tax return.

    You might have to pay a high-income child benefit charge if you or your partner earn over £60,000. You need to take this into account when you file your taxes.

    Self Assessment Tax return deadlines

    You need to file your Self Assessment tax return to HMRC before the deadline.

    • If you are obligated to submit a tax return and have not previously submitted one, you need to inform HMRC by 5 October by registering for Self-Assessment.
    • If you plan to file a paper tax return, make sure to submit it by midnight on October 31st.
    • When completing a tax return online, you submit it by midnight on January 31st.
    • Typically, there is an additional payment deadline of July 31 for those who make advance payments towards their tax bill, referred to as payments on account.

    Penalties

    Beware of the tax deadlines and their submission methods. HMRC will penalise you if you miss the Self Assessment tax submission deadline. Make sure to mark your tax deadlines so you don’t miss them.

    A late filing penalty of £100 will be imposed if your tax return is submitted up to 3 months past the deadline. The penalty amount will increase if the submission is delayed further and you pay your tax bill late.

    Additionally, interest will be applied to any late tax payments. If your tax return is overdue more than 3 months after the due date, you may calculate the potential penalty amount on the HMRC website and the penalties for late payment. Nevertheless, you have the right to appeal against the penalty if you have a reasonable justification.
