What happens if Colabs.Tech 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 23 January 2028.
| Companies House | Accounts delivered | Penalty |
|---|---|---|
| Up to 1 month late | 24 Jan 2028 to 23 Feb 2028 | £150 |

| 3 to 6 months late | 24 Apr 2028 to 23 Jul 2028 | £750 |
| More than 6 months late | From 24 Jul 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 May 2028 | £200 |
| 3 months late | 30 Jul 2028 | another £200 |
| 6 months late | 30 Oct 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 30 Apr 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.
