How To Declare Your Company Dormant In The UK (And What It Means)

If your limited company isn’t trading right now, you might be wondering whether it should be treated as a dormant company for Companies House and HMRC purposes.

For many small business owners, dormancy can be a useful “pause button” - you keep the company on the register (and keep using the same company number and trading vehicle later), without running it day-to-day.

But dormancy is commonly misunderstood. A company isn’t dormant just because you decide it is. In the UK, “dormant” has a specific meaning, and you can still have ongoing Companies House obligations even if you’re not doing any business.

Below, we’ll walk you through what a dormant company means in practice, how to approach it properly, and what to watch out for so you don’t accidentally trigger extra filings, tax admin, or penalties.

What Does It Mean To Declare A Company Dormant?

In practical terms, a company is “dormant” when it’s not carrying out business activities and has no significant accounting transactions during its financial year.

This matters because “dormant” isn’t just a description - it affects:

• what you file at Companies House (often simplified dormant accounts, if you qualify);
• whether you need to file a Corporation Tax return (HMRC may not require one for a dormant period, but it depends on your circumstances and HMRC’s records); and
• how HMRC administers your company for Corporation Tax purposes.

What Counts As A “Significant Accounting Transaction”?

Significant accounting transactions generally mean financial activity that must be recorded in your accounting records (beyond certain limited exceptions).

Common examples that may mean your company is no longer dormant include:

• issuing invoices or receiving customer payments;
• paying contractors or employees;
• buying stock, equipment, or paying business expenses;
• receiving interest or rental income;
• paying dividends;
• director loans in/out (these can create transactions that need recording - director funding should be structured carefully, often with a Director Loan arrangement in mind).

Some limited administrative items may be permitted without affecting dormancy (for example, certain statutory fees), but the rules can be technical. If you’re aiming to keep the company dormant, it’s usually safest to minimise money movement unless your accountant confirms it won’t affect dormant status.

Why Would A Small Business Want A Dormant Company?

Using dormancy can make sense if you:

• launched a company but haven’t started trading yet;
• paused trading while you pivot or raise funding;
• are taking a break (for example, parental leave or a sabbatical);
• want to keep a company “ready to go” for a future project (including ringfencing certain IP ownership within that company);
• set up a special purpose company for a future project.

That said, if you’re done with the company completely, keeping it dormant might not be the most efficient option - in some situations, it’s better to close the company properly (we’ll cover that later).

Is My Company Eligible To Be Dormant?

Before you try to treat your company as dormant, it’s worth checking whether your company is actually eligible - because the consequences of getting this wrong can be annoying (and sometimes expensive).

Common Scenarios Where Dormancy Works Well

• New company that hasn’t traded yet: You incorporated, but you’re still building your product, website, or preparing to launch.
• Company has stopped trading: You traded previously but have now ceased all business activity and want to keep the company “on the shelf”.
• Company holds assets but isn’t transacting: This can get tricky. Holding assets alone doesn’t always prevent dormancy, but any income (rent, royalties, interest) often does.

Things That Often Cause Problems

In the real world, small business owners accidentally “wake up” a dormant company with things like:

• keeping the business bank account active and paying software subscriptions;
• processing small payments “just to keep things moving”;
• paying themselves expenses;
• running payroll “because it’s easier to leave it set up.”

If you’re unsure, speak to your accountant (and if there are legal structuring questions - for example, who owns what, or how funding is recorded - it can help to get legal advice early).

How Do I Declare My Company Dormant? A Step-By-Step Process

There isn’t usually a single formal “switch” you file with Companies House to declare dormancy. In practice, dormancy is about ensuring the company meets the dormant conditions, then filing the right documents - and separately making sure HMRC treats the company as dormant for Corporation Tax administration.

The two key bodies involved are:

• Companies House (accounts and confirmation statement filings), and
• HMRC (Corporation Tax administration and related registrations).

Here’s a practical step-by-step approach.

1) Stop Trading And Stop “Significant” Transactions

First, make sure the company truly stops trading.

• Stop issuing invoices and taking customer payments.
• Cancel subscriptions and recurring charges where possible.
• Stop payroll and contractor payments.
• Be careful with director expenses and reimbursements.

If your company traded earlier in the year, you may need accounts up to the date trading stopped (your accountant can guide you on the accounting cut-off).

2) Consider Recording The Decision Internally

While not always legally mandatory in every case, it’s good governance to record a director decision that the company will cease trading and aim to be dormant - especially if there are multiple directors or shareholders.

This can be as simple as written board minutes or a short resolution. Keeping a clear paper trail can help later if you ever need to show when trading stopped (for example, to HMRC, your bank, or an investor during due diligence).

For governance hygiene, it’s also worth keeping proper Meeting Minutes even when a company is inactive.

3) Tell HMRC Your Company Is Dormant (If Needed)

If your company is within the Corporation Tax system, HMRC will often continue to issue notices unless they update their records to reflect that the company is dormant.

What you typically do is:

• contact HMRC (often through your business tax account or by letter/phone);
• tell them the date the company stopped trading; and
• ask HMRC to update their records for Corporation Tax purposes.

Important: HMRC’s position and Companies House filings don’t automatically update each other. You can file dormant accounts at Companies House and still receive HMRC correspondence if HMRC hasn’t updated its records.

Note: This article is general information only and isn’t tax or accounting advice. Your accountant can confirm what returns/registrations apply to your company (especially if you’ve traded during the period, have income, or remain registered for VAT/PAYE).

4) Prepare And File Dormant Accounts With Companies House

Even if your company is dormant, you generally still must file annual accounts with Companies House.

The good news: dormant accounts are usually simpler and can often be filed online.

Depending on your company type and size, you might file:

• Dormant company accounts (simplified format), and/or
• Micro-entity accounts if you qualify (still not “no work”, but lighter than full accounts).

If you’re trying to keep filings as light as possible, it’s worth understanding whether your company can file Full Accounts or whether you qualify for exemptions (your accountant can confirm what applies to you).

5) Keep Filing Confirmation Statements

This catches many directors out: dormancy does not remove your obligation to file a confirmation statement (usually annually) to confirm your company details at Companies House are up to date.

Even if nothing has changed, you still generally need to submit it on time.

6) Maintain Your Basic Company Records

Even dormant companies must keep statutory records up to date, including:

• register of members (shareholders);
• register of directors;
• PSC register (people with significant control);
• records of decisions and filings.

If ownership and decision-making arrangements aren’t clearly documented, it can create headaches later - particularly if you plan to restart trading, bring in an investor, or sell the company. In many small companies, this is where a properly drafted Shareholders Agreement can be a huge help.

What Are The Ongoing Legal And Tax Obligations For A Dormant Company?

Dormancy is not the same as “switching off” a company. You’re reducing activity - not eliminating compliance.

Companies House: Filing Deadlines Still Apply

If you miss filing deadlines, dormant companies can still receive:

• late filing penalties;
• prosecution risk (in serious cases of repeated non-compliance);
• strike-off action by Companies House.

So, even if you aren’t trading, you should diarise filing deadlines and keep your registered office address monitored.

HMRC: Corporation Tax, VAT And PAYE Can Still Be Relevant

Depending on your history and registrations, you may need to address:

• Corporation Tax: If the company traded and then stopped, there may be a final return due. If it’s newly incorporated and never traded, HMRC may accept that it’s dormant and stop issuing return notices (once their records are updated).
• VAT: If the company is VAT-registered, there can still be obligations (including nil returns) unless you deregister. Whether deregistration is appropriate is a tax/accounting question.
• PAYE: If you had employees, you may need to close the PAYE scheme and deal with any final payroll reporting.

In short: making a company dormant is often a combination of filing the right things at Companies House and ensuring your tax registrations and HMRC records reflect what’s actually happening - so you’re not stuck doing unnecessary admin.

Contracts, Data, And Other “Quiet” Legal Risks

A dormant company can still have legal risk if it has ongoing obligations under contracts or holds personal data.

For example:

• If you’ve got ongoing supplier contracts or software subscriptions, you may still be bound by those terms (and paying them may affect dormancy).
• If you collected customer personal data before going dormant, you still need to store and handle it lawfully under UK GDPR and the Data Protection Act 2018. In many cases, this means keeping an up-to-date Privacy Policy and having a clear retention/deletion plan.

If you’re unsure what obligations are still “alive” even when trading has stopped, it’s worth doing a short legal check-up rather than hoping it’ll be fine.

Dormant Vs Closing Your Company: Which Is Better?

This is one of the biggest strategic questions for small business owners.

If you plan to restart trading in the future, dormancy can be a sensible option. But if you’re done, keeping a company dormant can become an unnecessary admin burden.

When Keeping The Company Dormant Makes Sense

• You plan to relaunch soon (for example, within the next year or two).
• You want to preserve the company record, history, and structure.
• You expect to reuse existing contracts, IP, or brand assets (where they’re still owned by the company and can be used again).
• You’re keeping the company ready for investment or a future project.

When Closing The Company Might Be The Smarter Move

• You don’t plan to trade again.
• You want to stop admin and filing obligations altogether.
• You want to reduce risk of missing filings and getting penalties.
• The company has no assets and no reason to remain active.

Closing a limited company has its own legal and accounting steps (including dealing with assets, liabilities, and final filings). If that’s where you’re heading, the Close A Limited Company process is a better fit than dormancy.

Also keep in mind: if a company is dissolved, what happens to any remaining property can be complicated, so it’s important to deal with assets properly beforehand (including cash, domain names, IP, and equipment). This is discussed in Company Dissolved guidance.

Common Mistakes When You Declare A Company Dormant (And How To Avoid Them)

Most dormancy issues aren’t dramatic - they’re usually small oversights that snowball into late fees, messy accounts, or HMRC letters.

Mistake 1: Assuming Dormant Means “No Filings”

Even if dormant, you usually still need to file:

• annual accounts (dormant accounts); and
• confirmation statements.

Put reminders in your calendar and make sure the registered office is somewhere you actually check.

Mistake 2: Leaving Small Payments Running Through The Bank Account

That £15/month software subscription can create accounting entries and may mean the company isn’t dormant.

If you’re serious about dormancy, aim for:

• no bank movements other than limited permitted administrative items; and
• no trading income or business expenses.

Mistake 3: Forgetting HMRC Still Thinks You’re Trading

Companies House and HMRC don’t automatically “sync” in the way many people expect.

Even if you file dormant accounts, HMRC may still issue notices to deliver a Corporation Tax return unless they’ve updated your company’s status on their system.

Mistake 4: Not Cleaning Up Governance Before Hitting Pause

Let’s say you and a co-founder stop trading, and the company sits dormant for two years.

Then later, one of you wants to revive the business, bring in an investor, or sell the company. If there’s no clear agreement about:

• who owns what,
• who can make decisions, and
• what happens if someone wants out,

you can end up in a dispute - even though the company wasn’t “doing anything”. Putting those rules in writing early is often far cheaper than fixing them later.

Mistake 5: Treating Dormancy As A Substitute For Proper Legal Advice

Dormancy is a useful tool, but it isn’t a one-size-fits-all solution.

For example, if your company has:

• ongoing debts,
• investors and multiple shareholders,
• valuable IP, or
• existing contracts that are still “live”,

you’ll want tailored advice on what to do next (and what not to do) so you don’t accidentally create personal risk as a director.

Key Takeaways

• For a company to be dormant in the UK, it must not be trading and must have no significant accounting transactions in the relevant period.
• Dormant status can reduce admin (for example, simplified dormant accounts), but it does not remove your obligations to file accounts and confirmation statements with Companies House.
• You may also need HMRC to update their records so they treat the company as dormant for Corporation Tax administration - Companies House filings and HMRC records don’t always automatically align.
• Be careful with “small” bank account activity (subscriptions, reimbursements, payroll) because it can undermine dormancy and create unexpected accounting and tax admin.
• If you’re not planning to trade again, keeping a dormant company can be unnecessary - in some cases it’s more efficient to close the company properly instead.
• Even while dormant, your company should keep basic governance and records tidy (especially if there are multiple shareholders, assets, or future plans to restart trading).
