If you need to file a self-assessment tax return for the year to 5 April 2021, you have until midnight on 31 January 2022 to file your return if you have not already done so. You must also pay any tax that you owe for 2020/21 by the same date.
You will normally need to file a tax return if you have income in respect of which the associated tax is not collected at source. This will be the case if you are self-employed, or if you are a partner in a partnership. You will also need to file a self-assessment tax return if you have income from property, or if you have realised capital gains in the tax year, or if you have other sources of untaxed income, such as dividends, investment income or foreign income.
You can also choose to file a self-assessment tax return if you want to claim income tax reliefs.
If you or your partner received child benefit in 2020/21, check whether you fall within the scope of the high income child benefit charge. If you do, you will also need to file a return.
If you started trading in 2020/21 or became a landlord, you should have registered for self-assessment by 5 October 2021. If you have not done so, you should register as soon as possible so that you can file your return without delay.
If you received COVID-19 support payments in 2020/21, for example, grants under the Self-Employment Income Support Scheme (SEISS) or hospitality and leisure grants, you will need to report these on your 2020/21 tax return. The support payments are taxable. Grants received under the SEISS should be entered in the dedicated box in your self-assessment tax return, while any other taxable COVID-19 payments should be entered in the ‘any other business income’ box. Remember, to enter the amount that you received between 6 April 2020 and 5 April 2021, regardless of the date to which you prepare your accounts.
If you are employed and received grant payments under the Coronavirus Job Retention Scheme (CJRS), you do not need to enter these payments separately on your return – they are included in the figures on your P60.
The tax return filing deadline is the later of 31 January after the end of the tax year and three months from the date on which the notice to file a return was issued by HMRC. Where this is after 31 October 2021, the filing deadline will be later than 31 January 2022. For example, if the notice to file a return was issued on 1 December 2021, the return must be filed by 1 March 2022.
The deadline for filing a paper tax return was 31 October 2021 (or three months from the date of the notice to file where this was received after 31 July 2021). If a paper return is filed after that date, even if it is filed before 31 January 2022, it will be deemed to be filed late and a late filing penalty will be charged. Consequently, if you are filing your return to meet the 31 January 2022 deadline you must file it online. Remember that you must be registered with the Government Gateway and will need your details to login – make sure that you have these available in good time.
If you file your tax return online after midnight on 31 January 2022 (unless an extended deadline applies because the notice to file was issued after 31 October 2021) you will receive an automatic penalty of £100, even if you have no tax to pay. If you think you have a reasonable excuse for filing late, you can appeal against the penalty. However, HMRC usually take a harsh line on what they consider a reasonable excuse. Further penalties are triggered if your return remains outstanding three months, six months and 12 months after the deadline.
If you need help in filing your 2020/21 tax return, please get in touch. However, we suggest that you do not leave it until just before the filing deadline.
