Companies House Late Filing Penalty Calculator
Estimate the standard annual accounts late filing penalty for a private company or LLP using your due date, your effective filing date, and whether the previous financial year was also filed late.
This is an estimate for Companies House annual accounts late filing. It uses the standard private company and LLP penalty bands and gives a clear starting point, not legal or accounting advice.
Companies House Late Filing Penalty Calculator
Estimate the standard annual accounts late filing penalty for a private company or LLP using the due date, effective filing date, and repeat-late filing status.
What this estimate gives you
The result shows the standard late filing band, the base penalty, and the final amount after the repeat-late filing rule is applied.
It is designed for a quick practical estimate when you already know the due date and the effective filing date used by Companies House.
Rule summary
Standard Companies House penalty bands
For private companies and LLPs, the standard annual accounts penalty depends on how many calendar months late the filing is.
If the previous financial year was also filed late, the standard penalty is doubled after the late band has been identified.
| Lateness band | Standard penalty |
|---|---|
| On time or early | £0 |
| Not more than 1 month late | £150 |
| More than 1 month but not more than 3 months late | £375 |
| More than 3 months but not more than 6 months late | £750 |
| More than 6 months late | £1,500 |
Before you rely on this estimate
Confirm that you are using the correct Companies House filing deadline and the effective filing date for the estimate.
Special circumstances, rejected submissions, or official extensions can change the actual result.
Worked examples
How the result behaves in practice
More than 1 month late
If the filing passes the first calendar-month threshold after the due date, the filing moves into the next penalty band.
The estimate moves from £150 to £375 before any repeat-late doubling is applied.
Repeat late filing
If the same company or LLP also filed late in the previous financial year, the repeat-late rule applies.
The calculator doubles the standard penalty after identifying the correct lateness band.
Turn the result into an action plan
Confirm that you are using the correct Companies House accounts due date rather than an internal target date.
If the filing is already late, check the related filing deadline and overdue-risk tools so you can plan the next compliance step.
If the facts are unusual, keep evidence for any extension or appeal route before relying on the estimate externally.

FAQ
What happens if the filing date is on the due date?

Why does the result use month bands rather than simple day buckets?

Does repeat late filing always double the amount?
