What is a Dormant Company and Why Would You Have One?

Here’s a fact most directors do not expect: listed UK companies reportedly hold around 18,700 dormant subsidiaries, costing roughly £17 million a year in fees to keep them open. That tells you something important - a dormant company is not a mistake or a loophole. It is often a deliberate business decision.

But it is also one of those areas where business owners get caught out.

I’ve seen the same pattern more than once: someone sets up a company to protect a name, assumes “not trading” means “nothing to do”, then gets an HMRC letter or misses a Companies House filing deadline. That is where the confusion starts. Check the confusing difference between not trading and not making profit to avoid triggering an HMRC inquiry.

So, what is a dormant company, really? What does a dormant company mean in real terms? And do you need to tell HMRC company is dormant?

This guide breaks it down in plain English.

What Is a Dormant Company?

In practical terms, the definition of dormant company;

• the company is not buying or selling goods or services
• it is not earning money
• it is not paying wages or directors’ salaries
• it is not running normal business expenses through the company

What Does Dormant Company Mean for HMRC vs Companies House?

This is where people get tripped up.

A company can be dormant for Corporation Tax purposes, but you still have responsibilities at Companies House.

Quick comparison

The different definition of a dormant company by the two government bodies matters significantly, because some directors assume that if HMRC is not asking for tax, Companies House will also leave them alone. That is not how it works.

What Counts as a Significant Accounting Transaction?

A dormant business must avoid transactions that make it active again.

Transactions that usually mean the company is no longer dormant

Transactions that do not usually affect dormant status

So, if you are asking can a dormant company trade, the answer is simple:

Can a Dormant Company Trade?

No. A dormant company cannot trade and stay dormant.

The moment a dormant ltd company starts trading, receiving income, or putting significant transactions through its books, it stops being dormant.

Check what counts as significant transactions for Companies House, do not assume.

Why Would You Keep a Dormant Company?

This is one of the most common questions I hear from founders.

1. To protect a company name

A lot of people declare company dormant because they want to secure a name before they are ready to launch.

That is one of the most common answers to why would you keep a dormant company.

Selecting a name for a business involves a lot more complexity than you could imagine, a unique company name has huge impacts on your business. It helps you avoid company cloning scams and keep your data safe.

2. To pause trading without closing the company

Sometimes a business stops for a while because of:

• illness
• maternity or paternity leave
• travel
• restructuring
• funding delays
• a change in direction

In those cases, a uk dormant company can be a practical holding position.

3. To hold intellectual property or plans

Some owners use a company dormant structure to hold a brand, idea, or business identity they plan to use later. This may give you an altogether new idea of owning a shelf company.

4. To keep future flexibility

Closing a company and starting again later is not always the cleanest route. Keeping a dormant company uk entity in place can save time later. That is to keep your reputation in your selected industry.

What Happens If My Company Is Dormant?

If your company is dormant, three things matter most:

1. You still have filing duties at Companies House

Even if the company is completely inactive, you usually still need to file:

• dormant accounts
• a confirmation statement

All limited companies, including dormant companies and associations, must keep the public register updated.

2. You may not need to file Corporation Tax returns every year

Once you tell HMRC company is dormant and HMRC accepts that status, you will usually not need to file Company Tax Returns unless HMRC sends a notice asking for one.

3. You must avoid transactions that wake the company up

This is the part that catches people out.

A business bank account with tiny charges, interest, or stray subscriptions can be enough to create problems. If you want to keep the dormant company status clean, you need to stop those transactions.

Do I Need to Tell HMRC If My Company Is Dormant?

Yes - in most cases, you should.

You should tell HMRC company is dormant when:

• your company has been incorporated but has never traded
• your company used to trade but has now stopped
• you want HMRC to stop expecting normal Corporation Tax filings, where appropriate

If the company traded before going dormant, HMRC may still require:

• a final Company Tax Return for the active period
• payment of any Corporation Tax due
• closure of payroll, if relevant
• VAT deregistration, if relevant

In plain terms: if you want to declare company dormant, do not just stop using it and hope for the best. Make sure HMRC knows.

How to Declare a Company Dormant

If you want to declare company dormant, here is the practical process.

Step 1: Stop trading fully

Before you move to dormant status, deal with loose ends:

• finish contracts
• collect money owed in
• pay suppliers
• pay taxes due
• stop payroll
• cancel VAT registration if needed
• close or stop using the business bank account if charges will continue

Step 2: Tell HMRC

To tell HMRC company is dormant, contact HMRC’s Corporation Tax office and confirm:

• company name
• UTR
• the date the company became dormant

Step 3: Keep up with Companies House filings

You do not usually need to separately notify Companies House that the company is dormant. Instead, you show dormant status by filing:

• dormant accounts
• confirmation statements

Dormant Company vs Non-Trading Company

These terms get mixed up a lot, but they are not always identical.

So if you are asking what is dormant, the key point is this: not every non-trading company qualifies as a dormant company.

Can a Dormant Company Become Active Again?

Yes. A dormant company uk can be reactivated.

If the company starts trading again, you must usually:

• tell HMRC within
• register or reactivate Corporation Tax obligations
• resume normal accounting and filing
• file full accounts rather than dormant accounts where required

There is no need to overcomplicate this. The main thing is to tell HMRC on time and keep the records clean from the date trading restarts.

Common Mistakes With Dormant Companies

Leaving the bank account open

A few pounds of bank charges can undo the position.

Assuming Companies House does not need anything

It does. Dormant companies still file.

Forgetting HMRC

If you do not tell HMRC company is dormant, you can still receive tax notices and filing demands.

Trading “a little bit”

There is no safe middle ground here. If you are trading, you are not dormant.

FAQ About Dormant Companies

1. Can a dormant company own property or assets?

A dormant company can legally hold assets - including property, intellectual property, or shares in another company - without automatically losing its dormant status, provided there are no significant accounting transactions resulting from that ownership.

However, if the property generates rental income, incurs maintenance costs paid through the company, or triggers any financial activity, dormant status is broken. Holding companies that own assets passively are a legitimate use case, but you should confirm the specific position with an accountant before assuming the company qualifies as dormant.

2. What happens if a dormant company misses its filing deadline?

Companies House issues automatic late filing penalties for missed dormant accounts deadlines - starting at £150 for accounts up to one month late and rising to £1,500 for accounts more than six months late for private companies. If filings are repeatedly missed, Companies House can begin compulsory strike-off proceedings, which means the company could be dissolved without your consent.

Directors can also face personal liability in some circumstances. The good news is that dormant accounts are straightforward to prepare and file - missing the deadline is rarely justified, given how simple the process is

3. What is the difference between a dormant company and a dissolved company?

A dormant company still legally exists - it is registered at Companies House, has ongoing filing duties, and can be reactivated at any time.

A dissolved company has been formally struck off the register and ceases to exist as a legal entity. Dissolution is permanent unless you apply to restore it, which is a court process and not always possible. If you think you might use the company again, keeping it dormant is almost always the better choice. Dissolution should only be considered if you are certain the company is no longer needed. Check if you want to restore a dissolved company.

4. Can a dormant company have a bank account?

Technically, yes, but it creates risk. If the account generates bank charges, earns interest, or has any transactions passing through it, those can count as significant accounting transactions and break your dormant status with Companies House.

The safest approach is to close the business bank account or ensure it is completely frozen with zero activity. A dormant company should have no financial movement - even small, incidental charges can trigger compliance issues if left unaddressed.

5. Do I need to file a confirmation statement for a dormant company?

Yes. A confirmation statement (form CS01) is required every year, regardless of whether your company is dormant. It confirms that Companies House has up-to-date information about your company - its registered address, directors, shareholders, and SIC code. Dormant companies typically use SIC code 99999. Missing the deadline triggers an automatic penalty and, if ignored, can lead to Companies House beginning compulsory strike-off proceedings. This is one of the most common mistakes dormant company directors make.

6. Does a dormant company need to be registered for VAT?

No. A dormant company has no taxable turnover, so there is no requirement to register for VAT. If your company was VAT-registered before going dormant, you must deregister - either because your taxable turnover has dropped to zero or because you have stopped making taxable supplies.

Failing to deregister means HMRC will continue to expect VAT returns, which creates unnecessary filing obligations and the risk of penalties for non-submission. Deregistration is done via form VAT7 and should be handled as part of the process of making your company dormant.

7. Can a dormant company still have directors?

Yes, and it must. Every UK limited company - including a dormant one - is legally required to have at least one director at all times. Directors of dormant companies still carry their standard legal duties under the Companies Act 2006, including the duty to file accounts and confirmation statements on time.

Being a director of a dormant company is not a passive role from a compliance standpoint, even if there is no day-to-day business activity. If the sole director resigns without a replacement being appointed, the company falls into a legally problematic position that requires urgent attention.

8. Is a dormant company the same as a shell company?

Not exactly, though there is overlap. A dormant company is a defined legal and tax status - it means no significant accounting transactions and no trading activity.

A shell company is a broader, more informal term that generally refers to a company with no active operations, but it does not carry a specific legal definition in UK law and does not automatically imply dormant status.

A shell company may still have transactions, hold assets, or be used as part of a corporate structure in ways that would make it active for Companies House or HMRC purposes. If someone describes their company as a shell, you cannot assume it is dormant without checking the actual transaction history.

9. Can HMRC investigate a dormant company?

Yes. Declaring a company dormant does not place it beyond HMRC's reach. If HMRC has reason to believe the company has been trading, receiving income, or conducting activity inconsistent with dormant status, it can open an enquiry. This most commonly happens when bank records, third-party data, or discrepancies between a director's personal tax position and the company's declared inactivity raise a flag. Keeping clean records - even for a dormant company - is therefore important. If your company was active before going dormant, ensure all final returns were filed correctly and any outstanding tax was paid before notifying HMRC of dormant status.
