Dormant Company Registration Made Simple

A company registered with Companies House that is not currently trading or earning income. SIC code 99999 is used to indicate the company is dormant.

To reserve a company name, protect your brand, restructure your business, or hold assets before trading.

File Dormant Company Accounts (AA02) and a Confirmation Statement annually with Companies House.

Yes. Notify HMRC that your company is dormant for Corporation Tax using their online portal.

Indefinitely, as long as required filings are submitted to Companies House annually.

Yes, but avoid transactions to stay dormant. Many choose not to open a business bank account to maintain the company’s dormant status.

Start trading and inform HMRC within 3 months. You’ll need to file full company accounts.

Our Online Filings platform starts at just £29 + VAT, delivering a mobile-friendly, fast, and hassle-free service. The £50 Companies House fee is added at checkout—full transparency, no hidden costs.

Identity verification is a requirement introduced by the Economic Crime and Corporate Transparency Act 2023. Companies House is moving to a system where all company directors must verify their identity, and this requirement applies to filings submitted through Online Filings.

Online Filings is an Authorised Corporate Service Provider (ACSP) registered with Companies House and is supervised by HMRC for Anti-Money Laundering. Because of these obligations, we must verify the identity of all directors and all users before any filing can be submitted through our platform. This protects the integrity of the service and ensures that every filing we process is valid and compliant with UK law.

Directors using Online Filings must therefore complete identity verification before we can submit their filing. The process is fast, secure and takes less than two minutes on your smartphone. You can verify your identity using a UK driving licence, a UK passport or an international passport.

The Companies House Personal Code is an 11-character identifier you receive after completing identity verification with Companies House. From 18 November 2025, all directors, people with significant control (PSCs) and other key company officers must use this code when submitting filings such as confirmation statements and appointment forms.

You only need to verify your identity once. Your personal code will then apply to all your current and future roles and appointments. Keep your code secure, but you may share it with trusted professionals such as accountants, authorised agents or the Online Filings platform when they submit filings on your behalf.

When do I need to use my Personal Code?

• Directors: Use the code when filing the company's confirmation statement or when being appointed.
• PSCs who are not directors: Provide your code within 14 days of the start of your birth month.

Online Filings is officially approved by Companies House as an Authorised Corporate Service Provider. This status means we are trusted to submit your company filings directly to Companies House on your behalf, following rigorous compliance and security standards required by UK law.

As an ACSP, we must:

• Verify the identity of directors and people with significant control (PSCs) using government-approved processes.
• Follow strict anti-money laundering checks overseen by Companies House and a UK supervisory body such as HMRC.
• Protect your company from fraud and ensure your filings are always accurate, secure, and fully compliant with UK regulations.

Using Online Filings means your documents are managed by a government-recognised and highly regulated provider, giving you a smoother, safer, and more reliable experience.
