| Overview |
The Self-Employment Income Support Scheme (SEISS) provided grants to self-employed individuals and partners during the COVID-19 pandemic. SEISS grant income must be reported on the Self Assessment return for the tax year in which the grant was received. This article explains where to enter SEISS grant amounts in BTCSoftware.
| ⚠ Important: SEISS grants are taxable income. They must be entered in the specific SEISS boxes — not included in general turnover. Entering them in the wrong box may result in incorrect tax calculations or an HMRC compliance query. |
| Where to Enter SEISS Grants — Self Employment and Partnership |
The SEISS grant boxes are within the self-employment and partnership supplementary schedules:
| Schedule | Box | Description |
|---|---|---|
| Self-Employment Full (SA103F) | Box 70.1 | SEISS grant amount — page iii of the schedule |
| Self-Employment Short (SA103S) | Box 27.1 | SEISS grant amount — page ii of the schedule |
| Partnership Full (SA104F) | Box 9.1 | SEISS grant amount — page i of the schedule |
| Partnership Short (SA104S) | Box 9.1 | SEISS grant amount — page i of the schedule |
| Additional Step — SA100 Coronavirus Support Payments Tick Box |
After entering the SEISS grant amount on the relevant schedule, you must also complete a step on the SA100 core return:
- Open the SA100 (Tax Return) tab.
- Go to the Finishing Your Tax Return section.
- Tick Box 20.1 — Coronavirus support payments included.
- Save the return.
| ⚠ Important: Failing to tick Box 20.1 after entering a SEISS grant may cause a validation error or HMRC query. Both the schedule box and the SA100 tick box must be completed. |
| Frequently Asked Questions |
Q: What tax year do I enter the SEISS grant in?
A: SEISS grants are taxable in the tax year they were received, not when the claim was made. Grants 1 and 2 are taxable in 2020/21; grants 3, 4, and 5 are taxable in 2021/22.
Q: My client received a SEISS grant but has no self-employment income this year — do I still need to enter it?
A: Yes. The SEISS box must be completed even if the self-employment has ceased. Include the schedule in the return and enter the grant amount in the relevant SEISS box.
