| 3 to 6 months late | 8 Mar 2027 to 7 Jun 2027 | £750 |
| More than 6 months late | From 8 Jun 2027 | £1,500 |
Penalties double if the accounts were also late the year before.

| 1 day late | 1 Apr 2027 | £200 |
| 3 months late | 30 Jun 2027 | another £200 |
| 6 months late | 30 Sep 2027 | HMRC estimates the tax and adds 10% of the unpaid tax |
