Do Sole Traders Have a Company Registration Number?

Something we’re often asked here at SJD Accountancy by those relatively new to self-employment is: “Do sole traders have a Company Registration Number?” It’s a valid question given that every limited company has its own unique registration number, but one that can leave sole traders confused. So, getting right to it, do sole traders have a company number? And if not, why not? In this simple guide, we’ll explain why sole traders aren’t given a Company Registration Number and answer other commonly asked questions on the subject.

What is a Company Registration Number?

We’ll start by explaining what a Company Registration number is. Often referred to as a ‘CRN’, a Company Registration Number is a unique number assigned to an incorporated company. A CRN is a combination of 8 numbers and in most cases, letters given to one business, which shows that it has been registered with Companies House. This number is permanent and cannot be changed, regardless of whether a company changes its name, activities, directors or even shareholders. Businesses with a CRN can find it on their certificate of incorporation, along with any official correspondence sent by Companies House. Companies House has a register where you can search for a company by entering its CRN.

When might a CRN be used?

Incorporated businesses will need to use their CRN regularly, including:

Why don’t sole traders have a company number?

A sole trader business isn’t incorporated, which means it doesn’t need a company number. Looked at differently, the business isn’t legally separate from its owner, which is why sole traders are often referred to as their business. In contrast, a limited company is incorporated and has a separate existence from its owners. This is why limited companies need to be registered with Companies House, which is when they will receive a Company Registration Number.

Does it matter that sole traders don’t have a CRN?

It certainly won’t disadvantage you in any way, given it’s effectively just a number used to identify an incorporated company. If you’ve made the decision to operate as a sole trader, not needing to register your business (which is when you’ll receive your CRN) means the start-up process is even simpler.

So how do sole traders register?

Sole traders don’t need to register their business per se. Instead, you just need to register as self-employed for tax purposes, which is how you inform HMRC that you’ll pay Income Tax via the Self-Assessment Tax Return. Soon after having registered, you’ll receive a Unique Taxpayer Reference (UTR) from the government, which is how HMRC can identify you. Your UTR is a 10 digit code used to identify individual taxpayers and businesses who need to complete tax returns, including those who run their own limited companies.

Do sole traders ever need to incorporate their business?

Legally speaking, no. As a sole trader you are under no obligation to form a limited company at any particular stage. There are 3.5m sole trader businesses in the UK, which is a surefire sign that operating this way is a proven way to successfully work for yourself. That being said, there is a point at which forming a limited company may make sense. So at some stage, going limited might be worth further consideration.
