| More than 6 months late | From 1 Nov 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Aug 2027 | £200 |
| 3 months late | 31 Oct 2027 | another £200 |
| 6 months late | 31 Jan 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |

Filing notes for electrical contractors
Electrical contracting companies are often a director plus a van and tools. Most fall within the micro-entity rules, so the accounts filed at Companies House are short, and the CT600 carries the tax detail.
