Companies House vs HMRC: What’s the Difference?

If you’re planning to start a business in the United Kingdom, you’ve probably come across two names almost immediately: Companies House and HM Revenue & Customs (HMRC).

For many first-time business owners—particularly international entrepreneurs—these two organisations can seem confusing. Some believe they perform the same function, while others assume that registering a company with one automatically takes care of everything with the other.

The reality is quite different.

Understanding the difference between Companies House vs HMRC is essential if you want to keep your UK business compliant, avoid penalties, and focus on growing your company with confidence.

Think of it like this:

Companies House creates and maintains your company.
HMRC manages your company’s tax responsibilities.

One looks after your company’s legal existence, while the other ensures your business meets its tax obligations.

Whether you’re an Amazon seller, Shopify entrepreneur, consultant, freelancer, technology startup, or overseas investor, you’ll likely deal with both organisations at different stages of your business journey.

In this guide, we’ll explain:

What Companies House does
What HMRC does
The key differences between the two
Which filings go to each organisation
Common mistakes business owners make
How to stay compliant throughout the life of your company

Let’s start with the organisation that officially creates your business.

What Is Companies House?

Companies House is the official registrar of companies in the United Kingdom.

Its primary role is to incorporate companies and maintain the UK’s public register of businesses.

When someone says they have “registered a company in the UK,” they mean that their business has been incorporated with Companies House.

Every private limited company (Ltd), public limited company (PLC), and limited liability partnership (LLP) must be registered with Companies House before it can legally exist.

Once your company is approved, Companies House creates an official record of your business that anyone can search online.

This public register helps promote transparency and trust by allowing customers, suppliers, investors, banks, and other businesses to verify that a company is legally registered.

What Does Companies House Do?

Companies House is responsible for much more than simply registering new companies.

It manages the official lifecycle of every registered UK company by recording important legal information and making much of it publicly available.

Its responsibilities include:

Registering New Companies

When you incorporate a UK limited company, Companies House reviews your application and, if everything is in order, registers the business.

After incorporation, your company receives:

Certificate of Incorporation
Unique Company Number
Official incorporation date
Public company record

This is the legal beginning of your company.

Maintaining the Public Register

One of Companies House’s most important responsibilities is maintaining an accurate and transparent register of UK companies.

The register includes information such as:

Company name
Company number
Registered office address
Directors
Shareholders
Persons with Significant Control (PSC)
Filing history
Company status

Anyone can search this information to confirm whether a company is active and legally registered.

Recording Company Changes

Businesses evolve over time.

Companies House records changes such as:

Director appointments
Director resignations
Registered office address updates
Company name changes
Share allotments
Changes to Persons with Significant Control (PSC)

Keeping this information up to date is a legal responsibility for every company.

Receiving Confirmation Statements

Every UK limited company must periodically submit a Confirmation Statement.

This filing confirms that the information held by Companies House is accurate or updates it where necessary.

Although straightforward, it is one of the most important ongoing compliance requirements.

Receiving Annual Accounts

Companies House also receives annual accounts submitted by UK companies.

These accounts provide financial information about the company and form part of the public record, subject to the reporting requirements applicable to the business.

Promoting Corporate Transparency

One of the UK’s strengths is its transparent corporate system.

Companies House plays an important role in building trust by making company information accessible to the public.

This transparency helps banks, investors, suppliers, and customers make informed business decisions.

Why Is Companies House Important?

Without Companies House, there would be no official legal record of UK companies.

The organisation provides confidence that businesses are genuine, legally incorporated, and meeting their statutory filing obligations.

For international entrepreneurs, a UK limited company registered with Companies House often carries significant credibility when dealing with:

Overseas customers
International suppliers
Payment providers
Financial institutions
Investors
Online marketplaces

A professionally maintained Companies House record demonstrates that your business is operating within the UK’s recognised corporate framework.

What Documents Does Companies House Issue?

After successfully incorporating a company, Companies House issues several important documents.

Certificate of Incorporation

This is the official document confirming that your company legally exists.

It contains:

Company name
Company number
Date of incorporation

Many banks, payment providers, and commercial partners will ask to see this certificate.

Company Number

Every company receives a unique identification number.

Unlike your company name, this number never changes, even if you rebrand your business later.

Memorandum of Association

This document records the intention of the original shareholders to form the company.

Articles of Association

The Articles of Association establish the internal rules governing how the company operates, including director responsibilities, shareholder rights, and decision-making procedures.

Who Needs to Register with Companies House?

Companies House registration is suitable for a wide range of businesses, including:

Amazon sellers
Shopify businesses
eBay sellers
Etsy sellers
SaaS companies
Marketing agencies
IT consultancies
Import and export businesses
Technology startups
Freelancers choosing to incorporate
International entrepreneurs expanding into the UK market

Whether you are based in the UK or overseas, Companies House is the starting point for establishing a UK limited company.

Can Non-Residents Register with Companies House?

Yes.

One of the reasons the United Kingdom remains attractive to global entrepreneurs is that non-residents can legally register a UK limited company.

Founders from countries including India, Pakistan, Bangladesh, the United Arab Emirates, Nigeria, South Africa, Germany, Spain, Italy, Singapore, and many others successfully incorporate UK businesses every year.

In many cases, the entire process can be completed remotely without travelling to the UK.

However, you’ll still need to meet all legal incorporation requirements, including providing a UK registered office address and accurate information about the company’s directors, shareholders, and beneficial owners.

What Is HMRC?

Now that we’ve explored the role of Companies House, let’s look at the other organisation every UK business owner needs to understand—HM Revenue & Customs (HMRC).

If Companies House gives your business a legal identity, HMRC is responsible for ensuring your business meets its tax obligations.

HMRC is the UK’s tax authority. It collects taxes, administers tax reliefs, oversees customs duties, and helps ensure businesses and individuals comply with UK tax laws.

Every limited company, whether owned by a UK resident or a non-resident, should understand how HMRC works and when they may need to interact with it.

Although Companies House and HMRC often work alongside each other, they have completely different responsibilities.

What Does HMRC Do?

HMRC’s primary role is to collect taxes and administer the UK’s tax system.

Its responsibilities include a wide range of taxes and business-related obligations.

These include:

Corporation Tax
Value Added Tax (VAT)
PAYE (Pay As You Earn)
National Insurance Contributions
Self Assessment
Customs and Excise Duties
Import and Export Regulations
Capital Gains Tax
Stamp Duty

Unlike Companies House, HMRC does not register companies or maintain the public register of businesses.

Instead, it focuses on the financial and tax side of running a business.

Corporation Tax

One of HMRC’s most important responsibilities is administering Corporation Tax.

If your company is liable for Corporation Tax, it generally needs to register with HMRC and submit Corporation Tax returns in accordance with UK tax legislation.

Corporation Tax is charged on taxable profits, which may include:

Trading profits
Investment income
Chargeable gains from selling business assets

Keeping accurate financial records throughout the year makes Corporation Tax reporting much easier.

VAT Registration

HMRC is also responsible for VAT (Value Added Tax).

Not every business needs to register for VAT immediately.

Whether VAT registration is required depends on factors such as:

Taxable turnover
Nature of business activities
Whether voluntary registration would benefit the company

Once registered, businesses must comply with VAT reporting requirements and submit VAT returns when due.

PAYE and National Insurance

If your company employs staff or pays directors through payroll, HMRC administers the PAYE system.

PAYE is used to collect:

Income Tax
National Insurance Contributions
Student Loan repayments (where applicable)

Businesses operating payroll are responsible for submitting payroll information to HMRC and paying the appropriate amounts on time.

Import and Export Responsibilities

Businesses involved in international trade may also interact with HMRC.

This can include matters relating to:

Customs declarations
Import duties
Export procedures
EORI registration
International trade compliance

For importers and exporters, understanding HMRC requirements is essential for smooth cross-border operations.

Why Is HMRC Important?

Taxes play an essential role in every business.

HMRC helps ensure businesses contribute correctly while providing guidance on tax rules and compliance obligations.

Meeting HMRC requirements can help your business:

Avoid penalties
Build a good compliance record
Maintain accurate financial records
Operate confidently within UK regulations

Ignoring tax obligations can result in interest charges, penalties, or further compliance action.

Companies House	HMRC
Registers UK companies	Collects business taxes
Issues the Certificate of Incorporation	Administers Corporation Tax
Maintains the public company register	Administers VAT
Records directors and shareholders	Operates PAYE
Receives Confirmation Statements	Receives tax returns
Publishes annual accounts	Collects National Insurance
Records company changes	Oversees customs and duties
Maintains company information	Monitors tax compliance

A simple way to remember the difference is:

Companies House manages your company’s legal identity.

HMRC manages your company’s tax responsibilities.

Do Companies House and HMRC Work Together?

Yes, but they remain separate organisations with different responsibilities.

When a company is incorporated, certain information may be shared between the organisations where appropriate.

However, this does not mean that every tax-related requirement is completed automatically.

Business owners should understand that complying with Companies House obligations does not remove the need to meet HMRC requirements.

Likewise, paying taxes does not replace your legal filing responsibilities with Companies House.

Both organisations expect companies to keep accurate records and meet their respective deadlines.

Does Registering with Companies House Automatically Register You with HMRC?

This is one of the most common questions asked by new entrepreneurs.

The short answer is:

No.

Registering your company with Companies House creates the legal company, but it does not automatically complete all of your tax registrations.

Depending on your business activities, you may also need to consider:

Corporation Tax obligations
VAT registration
PAYE registration
EORI registration for international trade

Understanding these requirements early can help you avoid unnecessary delays and compliance issues.

When Will You Deal with Companies House?

You’ll normally interact with Companies House when dealing with your company’s legal records.

Examples include:

Incorporating a new company
Changing your registered office address
Appointing or removing directors
Updating shareholder information
Filing Confirmation Statements
Filing annual accounts
Changing your company name
Updating Persons with Significant Control (PSC)

Companies House is responsible for maintaining the official legal record of your company throughout its lifetime.

When Will You Deal with HMRC?

Your interaction with HMRC usually relates to taxation and financial reporting.

Examples include:

Registering for Corporation Tax where applicable
Registering for VAT
Running payroll through PAYE
Filing Corporation Tax returns
Submitting VAT returns
Paying business taxes
Importing or exporting goods
Applying for an EORI number

While Companies House focuses on legal company administration, HMRC focuses on tax compliance and revenue collection.

A Simple Real-World Example

Imagine you’ve just launched an online business selling products worldwide.

Your first step is to incorporate your company through Companies House. Once approved, your business officially exists as a UK limited company, and you receive your Certificate of Incorporation.

As your business begins trading and earning income, you’ll then need to understand your tax obligations. This is where HMRC comes in. Depending on your activities, you may need to register for Corporation Tax, VAT, or PAYE and submit the relevant returns on time.

In other words:

Companies House creates your company.
HMRC oversees your company’s tax responsibilities.

Understanding this distinction from the beginning helps you build a compliant and well-managed UK business.

Common Mistakes Business Owners Make

Understanding the difference between Companies House and HMRC is one thing—staying compliant with both is another.

Many new business owners, especially those setting up their first UK company, make avoidable mistakes simply because they assume one organisation handles everything.

Here are some of the most common errors.

Assuming Companies House and HMRC Are the Same

This is by far the most common misunderstanding.

Many entrepreneurs believe that once their company has been incorporated with Companies House, there is nothing else to do.

In reality, Companies House and HMRC have completely different responsibilities. Registering your company is only the first step. You must also understand and meet any tax obligations that apply to your business.

Missing Companies House Filing Deadlines

Every UK limited company has ongoing legal responsibilities.

Forgetting to submit documents such as Confirmation Statements or annual accounts can lead to penalties and, in serious cases, your company being struck off the register.

Keeping a compliance calendar is one of the easiest ways to stay organised.

Ignoring HMRC Tax Obligations

Some new business owners focus solely on incorporation and overlook tax responsibilities.

Depending on your circumstances, this could include Corporation Tax, VAT, PAYE, or other reporting obligations.

Failing to meet HMRC deadlines may result in interest, penalties, or further compliance action.

Using Incorrect Company Information

Incorrect director details, registered office addresses, or shareholder information can create unnecessary delays and future compliance issues.

Always ensure your company records remain accurate and up to date.

Poor Record Keeping

Good bookkeeping is essential for both Companies House filings and HMRC reporting.

Maintaining organised financial records throughout the year makes annual compliance much easier and reduces the risk of errors.

Companies House Filing Deadlines

Companies House requires companies to submit certain statutory filings throughout the life of the business.

Depending on your company’s circumstances, these may include:

Confirmation Statements
Annual accounts
Changes to directors
Changes to shareholders
Registered office updates
Changes to Persons with Significant Control (PSC)

Submitting these filings on time helps maintain your company’s good standing and keeps the public register accurate.

HMRC Filing Responsibilities

HMRC deadlines depend on your business activities.

Examples may include:

Corporation Tax returns
VAT returns
PAYE submissions
Employer reporting
Customs declarations (where applicable)

The exact obligations vary from one business to another, so it’s important to understand which requirements apply to your company.

Companies House and HMRC Timeline

To make the process easier to understand, here’s a typical journey for a new UK limited company.

Step 1: Register Your Company

Your company is incorporated through Companies House.

You receive:

Certificate of Incorporation
Company Number
Official company registration

Step 2: Begin Trading

Once your business starts operating, you should understand which HMRC obligations apply based on your activities.

Step 3: Maintain Company Records

Throughout the year, keep accurate accounting records and update Companies House whenever company information changes.

Step 4: Submit Required Filings

As deadlines arise, submit the required filings to both Companies House and HMRC where applicable.

Staying organised throughout the year makes compliance much easier than trying to prepare everything at the last minute.

Why Compliance Matters

Some entrepreneurs see compliance as paperwork.

In reality, it plays a much bigger role.

A well-managed company with accurate filings and timely submissions is often viewed more favourably by:

Banks
Payment providers
Investors
Suppliers
Customers
Potential business partners

Good compliance also reduces the risk of penalties and helps your business operate with confidence.
