What happens if ZLC 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 31 January 2027.

| 3 to 6 months late | 1 May 2027 to 31 Jul 2027 | £750 |
| More than 6 months late | From 1 Aug 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 May 2027 | £200 |
| 3 months late | 30 Jul 2027 | another £200 |
| 6 months late | 30 Oct 2027 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 30 Apr 2028 | 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 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.
