Dormant Company In The UK: Meaning, Setup And Compliance

Pressing pause on your limited company can be a smart move if you’re not actively trading right now. Maybe you’re between projects, waiting on funding, or simply not ready to wind up. In the UK, you can keep the company “on the shelf” as a dormant company - but you still have legal obligations to tick off each year.

In this guide, we’ll explain what a UK dormant company is, when dormancy makes sense (and when it doesn’t), the steps to make a company dormant, and what filings you must keep up with so you remain compliant and penalty‑free.

What Is A UK Dormant Company?

A UK dormant company is a registered company that isn’t doing business (no “significant accounting transactions”) during a financial year. The concept comes from Companies House: a company is considered dormant for Companies House if it has no significant transactions beyond unavoidable filings such as the confirmation statement fee, Companies House filing fees, penalties, or certain share‑related entries.

Key points to understand:

• Not trading means no sales, purchases, bank interest, wages, dividends, or business expenses (except allowed filings and minimal statutory costs).
• For HMRC (Corporation Tax) purposes, “dormant for Corporation Tax” means HMRC agrees the business has stopped trading and has no Corporation Tax to pay. You usually need to notify HMRC that the company is dormant.
• You still need officers, a registered office, and to keep statutory registers (e.g. directors, shareholders, PSCs) up to date under the Companies Act 2006.

Dormancy is not a loophole to ignore your obligations. You’ll still have to file accounts and a confirmation statement annually, even if there’s been no trading activity. If you want a step‑by‑step walkthrough, you can also review how to make your company dormant in the UK.

Dormant Vs Closed: Which Option Fits Your Plans?

Before you go dormant, decide whether it’s the right choice for your situation. Dormancy is best if you want to retain the company name and structure for future use, or keep IP, contracts, or regulatory registrations ready to reactivate later.

Dormancy may make sense if you plan to:

• Pause trading while you develop a new product or pivot your business model.
• Hold assets such as domain names or IP with no trading activity.
• Retain your company name and Companies House registration for branding or investor timelines.

Striking off (closing) may be better if you want to wind up fully and avoid ongoing filings. However, consider potential liabilities, outstanding debts, or future plans to restart. Even if you close, you still need to keep certain records for years after closure, so plan your record‑keeping carefully.

If you’re undecided, think about the timing of expected revenue, costs of keeping the company dormant, and any contracts or licences you might need to preserve. You’re not locked in forever - you can reactivate a dormant company when you’re ready to trade again.

How To Make Your Company Dormant Step‑By‑Step

There’s no formal “dormant” button at Companies House - it’s about meeting the definition and aligning your filings. Here’s a practical process small businesses typically follow.

1) Make A Board Decision And Record It Properly

Your directors should formally decide to stop trading and place the company into dormancy. Keep minutes of the decision for your records. It’s good practice to capture this in writing using appropriate Board Resolutions and follow your company’s constitution or articles.

Where your board regularly meets, ensure the process follows your normal governance around directors’ meetings so the decision is valid and documented.

2) Stop Trading And Close Down Active Operations

• Cease all sales and purchasing activities.
• Cancel or suspend subscriptions and services that could create accounting entries (e.g. software, utilities).
• Close business bank and merchant accounts, or ensure they are not generating transactions like bank charges or interest. Even small transactions can break dormancy.

3) Tell HMRC The Company Is Dormant

If HMRC has issued a notice to deliver a Corporation Tax return (CT600), speak to HMRC to confirm dormancy and whether a final return is needed. HMRC’s view of “dormant” focuses on trading for tax. In many cases, you’ll file a final CT600 for the last trading period and then mark the company dormant going forward.

Key tax steps to consider:

• Corporation Tax: confirm the dormancy date and whether future returns are required.
• VAT: if registered, cancel your VAT registration (unless you have specific reasons to keep it) to avoid filing obligations and potential errors.
• PAYE: close your PAYE scheme if you have no employees.

4) Keep Your Statutory Registers Accurate

Even while dormant, you must maintain statutory registers and keep the People With Significant Control (PSC) information correct. If anything changes (e.g. a director resigns or a shareholder transfers shares), update your records and make the necessary Companies House filings.

5) Prepare And File Dormant Company Accounts

Dormant companies must still file a set of accounts with Companies House each year. These are much simpler than trading accounts and, for many small companies, can be filed as “dormant accounts” if you meet the conditions.

Make sure your filings reflect the limited transactions you’re allowed to have. If there have been any significant accounting transactions, you may not be able to file dormant accounts and could need to file small company accounts instead. If in doubt, speak with your accountant early to avoid late filing penalties. For context on what’s required each year, it also helps to understand when and how to file accounts under the Companies Act 2006.

6) File Your Confirmation Statement On Time

You must file a confirmation statement annually confirming your company details (registered office, SIC code, officers, PSCs, share structure). Pay the Companies House fee - this is one of the few permitted transactions that won’t affect dormancy.

7) Protect Your Name And IP While Dormant

Dormancy can be a holding period before you relaunch. If your brand or logo is valuable, consider trade mark protection to stop others registering an identical or confusingly similar mark while you’re paused. You can do this even if you’re not trading, provided you have a genuine intent to use the mark in the near future.

Ongoing Filing And Compliance For A Dormant Company

Once dormant, think of your company as low‑maintenance - not no‑maintenance. Here’s what usually continues:

• Dormant accounts: filed annually with Companies House.
• Confirmation statement: filed annually with Companies House including PSC updates.
• Corporation Tax: HMRC may not require returns while dormant, but respond to any letters promptly and keep them informed if you reactivate.
• Record‑keeping: maintain statutory registers and keep your registered office address in good order so you don’t miss official letters.
• Data protection: if you still hold personal data (e.g. customer lists, former employee data), UK GDPR and the Data Protection Act 2018 continue to apply. Dormancy doesn’t switch off privacy law.
• Licences and insurance: cancel what you don’t need to reduce costs, but keep anything you legally require to hold (for example, professional indemnity if you’re retaining potential liabilities).

If you’ve decided to mothball for a few years, a quick annual diary note to review filings and check correspondence can save you a lot of hassle.

Common Risks, Penalties And Practical Tips

Even dormant companies can trip up. Here are frequent issues we see - and how to avoid them.

1) Accidental Transactions That Break Dormancy

Bank charges, interest, subscription fees, or paying a web hosting invoice can count as significant transactions. To reduce the risk:

• Close the company bank account if practical.
• Cancel subscriptions and standing orders.
• Avoid any payments that aren’t strictly permitted filings or penalties.

2) Missing Filing Deadlines

Late accounts or confirmation statements lead to fines and can even result in a prosecution of officers in serious cases. Set reminders and keep your registered office monitored. If you’re unsure what to file, get advice early - it’s cheaper than fines.

3) Confusing HMRC And Companies House Rules

Companies House dormancy focuses on “no significant accounting transactions.” HMRC focuses on whether you’re trading for tax purposes. You can be dormant for Companies House but still have tax exposure in some scenarios (for example, if you receive rental income or bank interest). Confirm your status with HMRC.

4) Overlooking Governance

Don’t forget the basics: accurately record decisions, maintain statutory registers, and update officer or shareholder changes promptly. If you’re adjusting the board during dormancy - for example, adding or removing directors - follow proper procedures for notices and filings. Keeping your governance clean with documented decisions and compliant filings reduces risk if you ever need to prove what happened and when.

5) PSC Information Out Of Date

PSC details must be kept up to date and confirmed every year in your confirmation statement. Changes in control or voting rights, even if you’re not trading, still need to be recorded and filed. If you need a refresher, revisit how PSCs work and what must be disclosed under the Companies Act via our guide to People With Significant Control (PSC).

6) Ignoring Privacy Law While “Inactive”

If you’re keeping old customer data “just in case,” remember UK GDPR still applies. You must have a lawful basis to retain it, secure it appropriately, and respect rights requests. If you eventually resume trading and start collecting data again, you’ll likely need a suitable Privacy Policy and to assess your data flows.

7) Losing Track Of Corporate Records

Even dormant companies must be able to produce company registers and historical records. If you later choose to close the company, note that you’ll need to retain certain records for several years after. Good record‑keeping will save time and stress when you restart or wind up properly.

Key Takeaways

• A UK dormant company is a limited company that isn’t trading and has no significant accounting transactions for a financial year, but it still has annual filings under the Companies Act 2006.
• Dormancy is useful if you plan to pause and relaunch later, keep your brand and structure in place, or hold assets without trading; closing (striking off) may be better if you want to end obligations entirely.
• To go dormant: record a board decision, stop trading, notify HMRC about the change, cancel VAT/PAYE where appropriate, keep statutory registers accurate (including PSCs), and file dormant accounts plus your confirmation statement on time.
• Watch out for accidental transactions like bank fees or subscriptions - they can break dormancy and force you to file full accounts. Close or freeze accounts and cancel non‑essential services.
• Set calendar reminders so you don’t miss accounts or confirmation statements. Late filings attract penalties and can escalate if ignored.
• If you need a deeper walkthrough, you can follow our practical guide to make your company dormant and brush up on how to file accounts, record decisions with proper Board Resolutions, and keep governance tight around directors’ meetings and PSC updates.
• When you’re ready to restart your venture or set up a new entity, make sure you choose the right structure and have your documents in place from day one - if you’re starting fresh, you can also register a company with a clean slate.
