What happens if MCB Fire 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 11 February 2028.

| 3 to 6 months late | 12 May 2028 to 11 Aug 2028 | £750 |
| More than 6 months late | From 12 Aug 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Jun 2028 | £200 |
| 3 months late | 31 Aug 2028 | another £200 |
| 6 months late | 30 Nov 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.
