For new companies, it is the anniversary of the last day in the month in which the company was incorporated.

You’ll need your Government Gateway ID and password – if you do not have one, first time service users can create one. Along with HMRC, you can also choose to file your accounts with Companies House, and for that, you will need your Companies House password and authentication code.

All the new businesses must file their first accounts within 21 months after company registration or 3 months from the accounting reference date - whichever is longer. The deadline for company accounts filing for existing businesses is 9 months after the company's financial year ends.

Companies House Late Filing Penalties

Failing to submit accounts on time incurs penalties, and the level of penalties depends on the duration of the delay.

If a company files accounts late for 2 consecutive years, the penalty will be doubled.

How to File Accounts for a Dormant Company

Every year, all limited companies, whether actively trading or not, must submit their annual accounts and a confirmation statement to Companies House. This requirement includes dormant companies as well.

A company is deemed 'dormant' when it is not engaged in business activities and has no other sources of income, such as investments. It's important to understand that the definition of 'dormant' varies for Corporation Tax, Company Tax Returns, and a company's annual filings with Companies House.

Once a company informs HMRC that it is dormant, it is not obligated to pay Corporation Tax or file another Company Tax Return unless specifically instructed to do so. However, even if a limited company is dormant for Corporation Tax purposes, it must still fulfill its obligation to file a confirmation statement and annual accounts with Companies House.

Companies House classifies a company as 'dormant' if it has not undertaken any 'significant accounting transactions' during the accounting period. These transactions do not include:

  • Filing fees paid to Companies House
  • Penalties for late filing of accounts
  • Initial money paid for shares during incorporation.

As long as no such transactions have occurred, the company can attain dormant status. If a dormant company also qualifies as 'small,' it has the option to submit 'dormant accounts' without including an auditor's report.

Rachel Roberts, head of compliance and enforcement for Companies House, clarifies that it’s the responsibility of the directors to run the company, ensure the proper preparation, and timely file company accounts and reports.

While a dormant company may not be actively conducting business, directors must remember that filing annual accounts and submitting confirmation statements to Companies House remains a legal requirement, even if the company has no intention of engaging in business activities or generating income.

Do dormant companies need to file accounts at Companies House?

Yes. Every limited company must file annual accounts and a confirmation statement with Companies House each year, even if it is dormant. A company is dormant when it has had no significant accounting transactions during the accounting period; filing fees, penalties, and initial share capital do not count. A dormant company that also qualifies as small can file simplified dormant company accounts, often a balance sheet and a few notes.

Can I prepare and file my own limited company accounts?

Yes, directors are free to prepare and file their own annual accounts with Companies House, and micro-entity or dormant accounts are often straightforward. For most trading companies, however, preparing statutory accounts involves applying accounting standards, calculating corporation tax, and disclosing director loans and related-party transactions. Many directors use an accountant to reduce the risk of errors, filing penalties, and HMRC enquiries, especially where the accounts also feed the CT600 return.
