What happens if Triangle Electrical Ltd files late
Companies House charges an automatic penalty the day after the deadline, and it rises the longer the accounts are late. These are the dates for this company's accounts due on 31 October 2026.

| 3 to 6 months late | 1 Feb 2027 to 30 Apr 2027 | £750 |
| More than 6 months late | From 1 May 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Feb 2027 | £200 |
| 3 months late | 30 Apr 2027 | another £200 |
| 6 months late | 31 Jul 2027 | 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.
