What happens if RDG Construction 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 22 January 2028.

| 3 to 6 months late | 23 Apr 2028 to 22 Jul 2028 | £750 |
| More than 6 months late | From 23 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 |

Filing notes for building contractors
Building companies often run the Construction Industry Scheme as a contractor, a subcontractor or both. CIS deductions suffered during the year are set against the PAYE bill, and any unrecovered balance at the year end matters when the accounts are drawn up.
