Dormant Companies In The UK: Meaning, When It Applies And Obligations

If you’ve set up a limited company but haven’t started trading yet, it’s common to wonder whether you can (or should) keep it dormant.

Maybe you registered a company name to “hold” it for later. Maybe you paused trading while you regroup. Or maybe you’ve got a second company sitting there for a future project.

Whatever your reason, “dormant” has a specific meaning under UK rules - and getting it wrong can create avoidable admin, tax issues, and filing headaches.

In this guide, we’ll break down what a dormant company is, when it applies, what you need to do with Companies House and HMRC, and the practical steps to stay compliant (without doing more than you need to).

What Does “Dormant” Mean For A Company In The UK?

In simple terms, a company is usually considered dormant if it has had no significant accounting transactions during a financial year.

That definition matters because it affects what you file, whether you need to submit Corporation Tax returns, and what records you should keep.

Companies House Vs HMRC: “Dormant” Can Mean Slightly Different Things

This is where small business owners can get tripped up: you might be dormant for one body but not the other.

• Companies House dormancy focuses on whether the company has had “significant accounting transactions” in the period.
• HMRC dormancy focuses on whether the company is “active” for Corporation Tax purposes (for example, whether it has started trading or has taxable income).

In practice, if your company truly hasn’t traded and hasn’t had income or meaningful transactions, you’ll often be able to treat it as dormant with both - but it’s important to check each position separately.

What Counts As A “Significant Accounting Transaction”?

As a general rule, most everyday business transactions count - for example:

• selling goods or services
• paying suppliers
• paying wages
• receiving income (including online platform payouts)
• paying for advertising, subscriptions, or software tools

If you’re doing those things, your company is unlikely to be dormant.

Some limited transactions are typically allowed while still being considered dormant - for example, certain fees paid to Companies House for filing (but you should always check your specific circumstances).

If you’re unsure whether something “breaks” dormancy, it’s worth getting advice early. It’s usually much easier to set things up correctly from day one than to unwind filings later.

When Does Dormant Status Apply (And Why Would You Use It)?

There are lots of perfectly legitimate reasons to keep a company dormant. For small business owners, the most common situations include:

1) You Registered A Company But Haven’t Started Trading Yet

This is probably the most common scenario. You’ve incorporated to secure the name, look professional, or prepare for investment - but you haven’t opened the doors yet.

Until you start trading (or receiving income), dormancy may apply and can reduce the complexity of your filings.

2) You Stopped Trading Temporarily

Maybe you’ve paused operations while you restructure, take a break, or switch direction.

If the company has truly stopped all trading activity and has no significant transactions in the year, it may be dormant for that accounting period.

3) You’ve Set Up A “Spare” Company For A Future Project

Some founders create additional companies for future brands, property projects, or joint ventures - and keep them dormant until the timing is right.

If that’s you, it’s still important to remember that dormancy isn’t “set and forget”. You’ll still have ongoing legal obligations.

4) You’re Keeping The Company Open While You Decide Whether To Close It

Sometimes you’re not sure whether to restart trading or shut the company down. A dormant period can be a holding pattern while you make that decision.

If you do decide it’s time to close, it’s worth reading up on the process for closing a limited company so you don’t accidentally leave loose ends (like assets, liabilities, or unresolved filings).

What Are Your Legal And Filing Obligations If Your Company Is Dormant?

Even if your company is dormant, it doesn’t disappear. It still exists as a registered legal entity - and that means you still have compliance responsibilities.

Companies House: Accounts And Confirmation Statements Still Matter

If your company is dormant, you’ll typically still need to:

• file annual accounts (often “dormant accounts”)
• file a confirmation statement each year to confirm key company details (directors, registered office, shareholders, etc.)
• keep statutory registers and basic company records up to date

Depending on the company’s size and circumstances, dormant accounts may be simpler than full trading accounts. Some companies may be eligible for exemptions and simplified filings - but you’ll want to check eligibility carefully. The rules around total exemption full accounts and filing options can be confusing, especially if your company is borderline dormant or has had unexpected transactions.

HMRC: Do You Need A Corporation Tax Return?

A common misconception is: “If my company is dormant, I don’t need to deal with HMRC at all.”

In reality, it helps to treat this as a two-step process:

1. Check whether HMRC treats the company as dormant for Corporation Tax purposes for the period.
2. Work out what HMRC filings (if any) are actually required - and make sure you don’t miss deadlines.

If your company has never traded and has no taxable income, HMRC may treat it as dormant and may not require a Company Tax Return for that period. However, if HMRC issues a notice to deliver a Company Tax Return, you generally must respond and file as required (or contact HMRC to confirm the position) rather than ignoring it.

Also keep in mind: “not trading” doesn’t always mean “no tax obligations”. Certain income or gains can still create a tax position, and different rules can apply depending on what activity has taken place. This article is general information only and isn’t tax advice - if you’re unsure, speak to an accountant or lawyer.

Directors’ Duties Still Apply (Even If You’re Dormant)

Dormant companies still have directors, and directors still have legal duties under the Companies Act 2006.

That includes duties like acting in the best interests of the company and keeping appropriate records.

Practically, that means:

• don’t assume you can ignore Companies House mail because “nothing’s happening”
• keep on top of filing deadlines
• make sure decisions are properly documented (especially if there are multiple shareholders or directors)

For example, if you decide to open a bank account, issue shares, appoint/remove a director, or change the registered office, you’ll want to document decisions properly (and file where required). A simple Company Resolution can be a clean way to record key decisions.

Common Ways A Dormant Company Accidentally Becomes Active

This is where we see small businesses get caught out. You might think the company is dormant - but small actions can create transactions that mean it’s no longer dormant.

Here are some common examples.

Opening And Using A Bank Account

Opening a bank account alone may not necessarily cause significant transactions - but once you start using it, you’re likely to create accounting entries.

Even simple things like:

• paying bank charges
• receiving a transfer
• paying for a website domain or hosting

can be enough to shift you out of dormancy.

Paying For Branding, Website Or “Getting Ready” Costs

It’s very common to start spending before you start selling - for example, paying designers, developers, or marketing costs.

Those are still transactions, and they often mean the company is not dormant for that period.

If you’re preparing to launch, it can also be a good time to get your legal foundations right - for example, your company structure and internal rules. Depending on your situation, you may need an Articles of Association review or updates (especially if you’re bringing on co-founders or investors).

Director Or Shareholder Loans (Including Paying Costs Personally)

Founders often pay early costs personally and plan to “sort it out later”. But reimbursement and loan arrangements can create accounting transactions.

Even if you’re not trading, movement of money between you and the company can affect whether the company is dormant from an accounting/tax perspective.

If you’re putting money into the company (or the company owes you money), it’s worth documenting it properly. A Director Loan arrangement can help avoid confusion later, particularly if the company restarts trading, brings in investors, or closes down.

Receiving Any Kind Of Income

Income is a strong sign your company is active - even if it’s not “sales” in the traditional sense.

Examples include:

• consulting income
• affiliate commissions
• rent or licence fees
• interest received

If money is coming in, you should assume the company is not dormant unless and until you’ve confirmed otherwise.

Making Decisions Without Recording Them

This one doesn’t necessarily affect dormancy directly, but it causes legal and practical problems down the track.

Even dormant companies can have important governance decisions - for example, appointing a new director, issuing shares, or changing shareholder details. Keeping clear records (and minutes where appropriate) helps you prove what happened and when.

If you’re holding occasional director meetings (even informally), having Board Minutes can make your compliance much cleaner.

What Should You Do If Your Company Stops Being Dormant (Or You Want To Start Trading)?

Good news: moving from dormant to active is very normal. The key is doing it intentionally, rather than accidentally.

Step 1: Identify The “Start Date” Of Activity

Pinpoint when the company starts trading or starts having transactions. This matters because it affects:

• your accounting records
• your tax position
• what filings you need for the relevant accounting period

Step 2: Tell HMRC (Where Required)

If your company starts trading, you generally need to make sure HMRC is aware the company is now active for Corporation Tax purposes. In many cases HMRC will have already set up Corporation Tax when you incorporated, but you should check what’s been issued and what deadlines apply.

If you expect taxable turnover, you may also need to consider VAT registration - that’s a separate topic, but worth flagging early so you don’t miss thresholds.

Step 3: Get Your Contracts And Internal House In Order

When you move out of dormancy, it’s often a sign you’re about to take on real business risk - customers, suppliers, hires, and obligations.

That’s usually the right time to put the right documents in place, such as:

• customer terms and conditions
• supplier/service agreements
• founder/shareholder arrangements (if there’s more than one owner)
• employment paperwork if you’re hiring

If you’re setting up from scratch (or re-launching), it may help to revisit the basics of Register A Company requirements and make sure your structure still suits your goals.

Step 4: Consider Whether Staying Dormant Is Still The Right Choice

Sometimes, once you look closely, you’ll realise the company isn’t dormant at all - it’s just “quiet”. In that case, you may be better off treating it as active and filing the correct accounts, rather than trying to force dormancy and risking incorrect filings.

And if you’re not going to use the company again, closing it might be the most efficient option.

Key Takeaways

• A company is usually considered dormant if it has had no significant accounting transactions in the financial year, but “dormant” can be assessed slightly differently by Companies House and HMRC.
• Even if your company is dormant, you’ll generally still need to file annual accounts and a confirmation statement, and directors’ legal duties still apply.
• Small actions can accidentally break dormancy, including paying for website/branding costs, using a bank account, reimbursing expenses, or receiving any income.
• If your company becomes active, you should identify when activity started, ensure HMRC is updated where required, and get your business contracts and internal documents in place.
• If you’re not sure whether your company is truly dormant, it’s worth getting advice early - it can save you time, cost, and compliance stress later.
