What happens if Waterguys 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 29 January 2027.

| 3 to 6 months late | 30 Apr 2027 to 29 Jul 2027 | £750 |
| More than 6 months late | From 30 Jul 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 30 Apr 2027 | £200 |
| 3 months late | 29 Jul 2027 | another £200 |
| 6 months late | 29 Oct 2027 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 29 Apr 2028 | another 10% of any unpaid tax |

Filing notes for plumbing and heating companies
Plumbing and heating companies frequently work under CIS for main contractors and also directly for homeowners, so turnover can mix CIS and non-CIS income.
