| 3 to 6 months late | 6 Jun 2027 to 5 Sep 2027 | £750 |
| More than 6 months late | From 6 Sep 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |

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

Filing notes for property development companies
Many property development companies are single-project vehicles. Stock of land and buildings sits on the balance sheet as work in progress until sale, and a company that has finished its project may become dormant rather than close.
