Using software to file your company's information
How to send information to Companies House using third party software or by developing your own software.
Software filing packages let you send information to Companies House through our extensible markup language (XML) gateway.
Using software to file might be helpful if you file a lot of documents with Companies House. The more documents you file, the more benefit you are likely to get from using software.
It also costs less to file documents digitally using software.
You can file most information with Companies House using software. This includes types of company accounts and incorporations you cannot file through our web services.
How to file online using software
You’ll need to apply to file with Companies House using software. We’ll create your presenter account and give you a presenter ID and code.
If you need to file documents with a fee, you must apply for a Companies House credit account.
If you need to file charge (mortgage) documents for other companies, you must register as a lender.
You can either:
- buy third party software
- develop your own software
Developing your own software
You’ll need expertise in XML. You can:
- read and download our technical specifications
- visit our XML schema page for all transaction types and submission processes
Filing annual accounts in iXBRL format
We can receive and process company accounts produced in inline extensible reporting language (iXBRL) format. More software package providers are making iXBRL format available.
Some of the benefits include:
- no more covering letters
- no postage costs
- faster, more secure delivery with immediate acknowledgement of receipt
- automatic confirmation of acceptance or rejection
- reduced risk of late filing penalties
You can only use our iXBRL service to file accounts under the Companies Act 2006.
Previewing your submission
If you’re developing iXBRL to file accounts online, you can test your submission using our validator.
You should use the ‘show image’ tool to check your iXBRL submission. This will preview exactly how your image will look on our system.
Your submission might not display as you expect, even if it’s passed the validation process. This is because of the different methods used to render the iXBRL.
Validation for ‘average number of employees’ in accounts notes
The note ‘Average number of employees during the period’ is compulsory. We’ll reject your accounts if they do not include this information.
The validation will apply to:
- all company types (except dormant)
- financial years beginning on or after 1 January 2016
If we receive a public complaint about a company who has filed accounts before 13 October 2020 but did not include the note - we’ll write to the company and suggest they file amending accounts (under section 454 of the Companies Act 2006). A company could choose to file amending accounts voluntarily to prevent any complaints.
Small and micro entity company types must also include this note under the Companies, Partnerships and Groups (Accounts and Reports) Regulations 2015.
Accounts taxonomies
You can now file accounts using the 2023 FRC suite of taxonomies, which allow the filing of interim, initial and medium audited accounts.
You can use our iXBRL filing service for accounts tagged using the following taxonomies.
