Late filing penalties at Companies House

What a late set of accounts costs a private company, and what to do next.

At a glance

  • Up to 1 month late: £150
  • 1 to 3 months: £375
  • 3 to 6 months: £750
  • Over 6 months: £1,500
Quick answer
A private company that files accounts late is charged £150 if up to one month late, £375 if one to three months late, £750 if three to six months late and £1,500 if more than six months late. The penalty doubles if the company is late two years in a row.

The penalty amounts

How late the accounts arePenalty for a private company
Up to 1 month£150
1 to 3 months£375
3 to 6 months£750
More than 6 months£1,500

These penalties are charged to the company by Companies House. They apply automatically once the deadline passes.

When the penalty doubles

If the company files its accounts late two years in a row, the penalty is doubled the second time. A first offence at over six months costs £1,500, but a repeat can be much higher.

That is why filing late once is a warning. Getting back on schedule protects you from the doubled amount.

Who is responsible

The directors are responsible for filing on time, even when an accountant helps. The penalty is charged to the company, and Companies House can take further action if accounts stay unfiled for a long time.

If you have an accountant, agree who is watching the dates. We set up every deadline when you order.

What to do if your accounts are late

File as soon as possible, because the penalty rises with time. Our late accounts filing service prepares and files quickly. If you are many months or years behind, see our overdue accounts filing service.

Can you appeal a penalty?

You can appeal to Companies House if you had a reasonable excuse, such as serious illness or an event outside your control. Reasons such as lack of records or relying on someone else are not usually accepted.

If you plan to appeal, file the accounts first. Appeals are not considered while accounts are still outstanding.
