What happens if Inphase 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 21 May 2028.

| 3 to 6 months late | 22 Aug 2028 to 21 Nov 2028 | £750 |
| More than 6 months late | From 22 Nov 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Sep 2028 | £200 |
| 3 months late | 30 Nov 2028 | another £200 |
| 6 months late | 28 Feb 2029 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 31 Aug 2029 | 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.
