What happens if Mivaki 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 6 November 2027.

| 3 to 6 months late | 7 Feb 2028 to 6 May 2028 | £750 |
| More than 6 months late | From 7 May 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |

| 1 day late | 29 Feb 2028 | £200 |
| 3 months late | 28 May 2028 | another £200 |
| 6 months late | 28 Aug 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 28 Feb 2029 | another 10% of any unpaid tax |

Filing notes for civil engineering contractors
Civil engineering contractors usually carry plant and machinery, so capital allowances (the annual investment allowance and the main pool) do much of the work in the corporation tax computation.
