When your confirmation statement is due, the 14-day filing window, and what it costs to file.
The confirmation statement has its own deadline and fee, separate from your annual accounts. Both are easy to get right once you know the dates.
When it is due
You must file a confirmation statement at least once every 12 months. The 12-month review period starts the day after your last statement (or your incorporation date for a new company). You then have 14 days after the period ends to file.
The fee
There is an annual fee: £50 online through WebFiling or software, or £110 for a paper CS01 by post. You pay it once per 12-month payment period, however many statements you file in it.
What happens if you miss it
There is no automatic financial penalty for a late confirmation statement, unlike accounts, but the company and its officers can be prosecuted and the company can be struck off the register. It is best not to leave it.
