There are automatic late filing penalties which are designed to encourage companies to file their accounts and reports on time. All companies, private and public, large or small, trading or non-trading must send their accounts to Companies House.
Companies House is advising businesses to take appropriate measures to file on time. If, immediately before the filing deadline, it becomes apparent that accounts will not be filed on time due to your company being affected by Coronavirus (COVID-19), you may make an application to extend the period allowed for filing. You must apply for the extension before your filing deadline. The best way to file is online.
If you do not apply for an extension and your accounts have been filed late, an automatic penalty will be imposed. The registrar has limited discretion to cancel the collection of a penalty.
Companies House has stated that each appeal is treated on a case-by-case basis, and they already have policies in place to deal with appeals based upon unforeseen poor health. Appeals based upon COVID-19 will be considered under these policies.
