If you have received one or more grants under the Self-Employment Income Support Scheme (SEISS), it is important that you report the payments correctly on your tax return.

2020/21 self-assessment tax return
SEISS grants that were received in the 2020/21 tax year (i.e., between 6 April 2020 and 5 April 2021) should be reported on your 2020/21 self-assessment tax return, regardless of the date to which you prepare your accounts. The return must be filed online by midnight on 31 January 2022 (or by 31 October 2021 if you file a paper return). The first three grants under the scheme were paid in the 2020/21 tax year.

If you have already filed your 2020/21 tax return, HMRC may adjust your return if the information that they hold on the SEISS payments that have been made to you does not match what is shown on your return.

How to report SEISS payments
Grant payments received under the SEISS should not be included in turnover. Instead, they should be reported separately on the 2020/21 tax return in the box for Self-Employment Income Support Scheme grants. The location of the box depends on which self-assessment tax return is completed. It can be found:

• on page 2 of the ‘other tax adjustments’ section on the self-employment pages (SA103F) of the full return;
• in the ‘other tax adjustments’ section of the self-employment (short) page (SA103S);
• on page 2 of the ‘trading or professional profits’ section of the partnership return; and
• in section 3.10A of the SA200 short tax return.

HMRC corrections
HMRC will check the SEISS grants payments reported in the return against their records of the grants that have been paid to you.

If you have already submitted your 2020/21 tax return, and the amount of the SEISS payments that you reported on your return did not tally with HMRC’s records, HMRC will adjust your return to match their records and they will send you a revised tax calculation.

It is advisable that you check the figures on HMRC’s revised calculation against your records of the grants received. You can check the amounts that you have received either by logging into the SEISS claims service or against your bank statements for the account into which the payments were made.

If you do not agree with HMRC’s revised figures, you should contact their Coronavirus (COVID-19) helpline for businesses and self-employed people.

Failure to report SEISS payments
If you received one or more grants under the SEISS in 2020/21 and do not include them on your self-assessment tax return for that year, HMRC will adjust your return to reflect the payments and send you a revised tax calculation. As a result, you may find that you owe more tax than you expected, have an unexpected tax bill, or that the tax repayment you were expecting is reduced.

SEISS payments reported in the wrong box
If you included SEISS payments in your 2020/21 tax return, but did not enter the amount that you received in the designated box, for example, because you included it in turnover or entered it in one of the ‘other income’ boxes, you will need to amend your self-assessment tax return so that the grants are entered in the correct box and removed from the wrong box. If you do not do this, the grant income will be assessed twice, as HMRC will adjust the return to enter details of grants received in the correct box (but will not remove the income from elsewhere in the return).

Failure to complete a self-employment or partnership page
To qualify for the SEISS grants for 2020/21, you had to be trading in that tax year. If you have not completed a self-assessment or partnership page, HMRC will assume that you were not trading, and therefore ineligible for the grants. Consequently, they will seek to recover any grants that were paid to you.

If you were trading, but omitted to complete the relevant pages, you should amend your tax return to reflect this.

Appeal if you disagree with HMRC’s adjustments
If you do not agree with the changes that HMRC have made to your tax return in respect of your SEISS grant payments, you can appeal. However, you must do this within 30 days of the date on the SA302 letter advising you of the changes that they have made to your return.

HMRC have not yet taken account of changes that were made to 2020/21 tax returns before 19 June 2021. If you corrected your return before that date, you do not need to contact HMRC as they will process the amendments separately.
