What happens if Eilx Limited 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 17 March 2028.
| Companies House | Accounts delivered | Penalty |
|---|---|---|
| Up to 1 month late | 18 Mar 2028 to 17 Apr 2028 | £150 |
| 1 to 3 months late | 18 Apr 2028 to 17 Jun 2028 | £375 |
| 3 to 6 months late | 18 Jun 2028 to 17 Sep 2028 | £750 |
| More than 6 months late | From 18 Sep 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Jul 2028 | £200 |
| 3 months late | 30 Sep 2028 | another £200 |
| 6 months late | 30 Dec 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 30 Jun 2029 | another 10% of any unpaid tax |
For returns filed on or after 1 April 2026. Late three times in a row and the £200 penalties become £1,000 each.

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.
