| 3 months late | 28 May 2028 | another £200 |
| 6 months late | 28 Aug 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.
