What happens if Quinteq 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 28 February 2027.

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