Companies that file on deadline day file worse accounts
On the busiest filing days of the year, the share of accounts showing a deficit rises by three percentage points.
Company accounts are not filed evenly. They arrive in waves, on the statutory deadlines, and the waves look different from the quiet days. On the 14 days when more than 15,000 sets of accounts were filed, 19.2 per cent reported liabilities larger than assets. On the other 46 days it was 16.2 per cent.
Key points
- Deadline days run at 19.2 per cent in deficit against 16.2 per cent on ordinary days.
- The busiest single day in the series saw 44,704 filings.
- The gap is consistent across 60 days and 807,357 filings.
What happened
Private companies have nine months from their financial year end to file accounts, and public companies six. Because most companies incorporate at the same few points in the year, the deadlines bunch, and Companies House receives several times its normal volume on a handful of dates.
The numbers
Across 60 publishing days and 807,357 filings, the pattern holds.
| Day type | Days | In deficit |
|---|---|---|
| Days above 15,000 filings | 14 | 19.2% |
| All other days | 46 | 16.2% |
The busiest days in the series
| Date | Filings | In deficit |
|---|---|---|
| 2026-07-01 | 44,704 | 20.0% |
| 2026-06-30 | 34,696 | 18.7% |
| 2026-08-01 | 32,189 | 20.1% |
| 2026-06-20 | 30,270 | 19.4% |
| 2026-09-01 | 27,501 | 19.8% |
| 2026-07-31 | 23,430 | 19.7% |
Why it might be so
The obvious reading is that companies in difficulty leave filing until the last permitted day, while companies in good order file when their accountant finishes. That is plausible and this data cannot prove it. What the data does show is that the two populations differ, consistently, and by enough to matter.
There is a duller possibility worth stating: deadline days may simply contain a different mix of company sizes and industries, and the deficit rate may be following that rather than any behaviour. Separating the two needs more of the series than we have yet.
What happens next
The next statutory bunching is visible in the data before it arrives, because filing volume climbs for several days ahead of it. We will report each one against this baseline.
How this was produced. Companies House publishes every set of accounts filed with it as open data. Cap News downloads that file each working day, reads the tagged figures out of each filing and joins them to the company register. Nothing here is hand picked. The method sets out what is counted and what is not.
