What happens if Sunmax Elec 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 July 2027.

| 3 to 6 months late | 1 Nov 2027 to 31 Jan 2028 | £750 |
| More than 6 months late | From 1 Feb 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Nov 2027 | £200 |
| 3 months late | 31 Jan 2028 | another £200 |
| 6 months late | 30 Apr 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 31 Oct 2028 | another 10% of any 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.
