UK Dormant Company Status: Requirements, Filings & Pitfalls to Avoid

Imagine you set up a limited company in the UK for a project that never quite took off. Or perhaps you bought shares in a shell company for future use and haven't started trading yet. You might think your job is done once the paperwork is filed. But here’s the catch: silence doesn’t mean freedom from responsibility. Even if your business isn’t making money, spending cash, or hiring staff, dormant company status requires strict adherence to specific legal obligations.

If you get this wrong, you could face penalties from Companies House or HMRC, even though you’ve earned zero revenue. The rules are tighter than many directors realize, especially with changes introduced in recent years regarding audit exemptions and banking activity. Let’s break down exactly what it takes to keep your company dormant without breaking the law.

What Actually Defines a Dormant Company?

First, we need to clear up a common misconception. Being "inactive" isn’t enough. To qualify as dormant under the Companies Act 2006, your company must have had no significant accounting transactions during the financial year.

This definition is stricter than most people expect. A transaction is considered significant if it involves more than just administrative costs. For example:

• Allowed (Non-significant): Paying the annual confirmation statement fee to Companies House (£13 as of 2025/2026). Paying fees for statutory audits if required. Interest charged on bank overdrafts specifically for keeping the account open (though this is risky).
• Not Allowed (Significant): Buying office supplies. Paying for domain names or hosting. Receiving dividends. Making loans to directors. Any payment related to trading activities.

If your company receives any income-even £1-it loses its dormant status immediately. This includes interest earned on bank balances. If your company sits in a high-interest savings account and earns £50 in interest, that is a taxable event and a significant transaction. You can no longer file dormant accounts; you must file full accounts and pay Corporation Tax on that interest.

The Two Pillars of Compliance: Companies House vs. HMRC

Many directors make the mistake of thinking one government body covers everything. They don’t. In the UK, you have two separate regulators watching your dormant company, and they speak different languages.

Companies House cares about public transparency and corporate structure. HM Revenue and Customs (HMRC) cares about tax liability. You must satisfy both, often with different forms and deadlines.

Filing Dormant Accounts with Companies House

When your financial year ends, you have nine months to submit your accounts. For a dormant company, these are called "dormant company accounts." They are much simpler than standard full accounts. You don’t need a profit and loss statement showing turnover because there is none. Instead, you submit a balance sheet and notes confirming the company has not been active.

Here is the critical part: Audit Exemption. Under Section 479A of the Companies Act 2006, dormant companies are generally exempt from having their accounts audited by an external accountant. This saves you hundreds, if not thousands, of pounds annually. However, this exemption is lost if:

1. Your company was trading at any point during the year before becoming dormant.
2. You fail to file the dormant accounts on time.
3. Your company is a parent company in a group that does not qualify for small company audit exemption.

If you lose the audit exemption, you must hire a qualified auditor. The cost of an audit for a simple dormant company can range from £500 to £1,500 depending on the firm. It’s far cheaper to stay compliant and keep the exemption.

Navigating HMRC and Corporation Tax

Just because you filed with Companies House doesn’t mean you’re done. HMRC operates independently. When you incorporate a company, you receive a Unique Taxpayer Reference (UTR) for Corporation Tax. HMRC expects a return every year unless they are explicitly told otherwise.

To avoid receiving a CT600 form (the Corporation Tax Return) every year, you should write to HMRC to request exemption from filing Corporation Tax returns. This is often overlooked. If you don’t ask, HMRC will send you the form. If you ignore it, you’ll get penalties. If you fill it out incorrectly, you risk triggering an investigation.

Even if you are exempt, there are scenarios where you must file:

• Interest Income: As mentioned, if your bank account generates interest, you must file a return and pay tax on it. The rate is typically 19% (check current rates for 2026).
• Capital Gains: If you sell assets (like property or shares) held by the company, you trigger a tax event.
• VAT: If you were previously VAT registered, you must deregister if your turnover drops below the threshold, but you still need to notify HMRC.

The Confirmation Statement: Don’t Forget This Step

Every company, whether active or dormant, must file a Confirmation Statement (formerly known as the Annual Return). This document confirms that the information Companies House holds about your company is up to date. It covers:

• Registered office address
• Directors and secretaries
• Shareholders and share capital
• People with Significant Control (PSC)

You must file this within 14 days of the confirmation period end date. The fee is £13 if filed online. Missing this deadline results in a criminal offense for the directors, though prosecution is rare for first-time minor delays. However, persistent failure can lead to the company being struck off the register involuntarily.

Banking Activity: The Silent Killer of Dormancy

One of the biggest traps for dormant companies is the bank account. Many banks charge monthly maintenance fees or require minimum balances. If your bank deducts £5 per month for account maintenance, that is a significant accounting transaction.

Technically, this disqualifies you from filing dormant accounts. While some accountants argue that purely administrative bank charges are negligible, the safest route is to:

1. Close the company bank account entirely if it’s not needed.
2. Use a free business account that has no monthly fees.
3. If you must keep a paid account, be prepared to file full accounts instead of dormant ones, declaring the bank charges as expenses.

Also, watch out for direct debits. Did you forget to cancel a subscription for cloud storage or a software tool? That recurring payment counts as a transaction. Regularly check your bank statements for any outgoing payments.

Personal Liability for Directors

As a director, you have personal duties. Under the Companies Act, you must ensure accounts are delivered on time. Failure to do so can result in fixed penalty notices starting at £150 for late filing, increasing with time. More seriously, if you knowingly allow a company to trade while insolvent or fail to keep proper records, you can be disqualified from acting as a director for up to 15 years.

Additionally, remember your personal tax obligations. If you hold shares in the dormant company, you must declare them in your Self-Assessment tax return. You aren’t paying tax on the shares themselves unless you sell them, but HMRC needs to know you own them.

When Should You Strike Off Your Company?

If you have no plans to use the company in the foreseeable future, maintaining it is a waste of time and money. Consider applying for voluntary strike-off using form DS01. This removes the company from the register permanently.

However, you cannot apply for strike-off if:

• The company has changed its name in the last three months.
• It has traded or sold assets at undervalue in the last 12 months.
• It is involved in court proceedings.
• There is an arrangement with creditors.

Strike-off is usually the best option for truly unused entities. It stops all future filing obligations and fees.
