| 3 to 6 months late | 6 Apr 2028 to 5 Jul 2028 | £750 |
| More than 6 months late | From 6 Jul 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |

| 1 day late | 6 Apr 2028 | £200 |
| 3 months late | 5 Jul 2028 | another £200 |
| 6 months late | 5 Oct 2028 | HMRC estimates the tax and adds 10% of the 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.
