Becoming self-employed in the UK is one of the most significant and exciting things you can do in your career. Being your own boss, having full control to run your own business and forging your own path is highly rewarding, and these are just some of the many reasons why there’s been a big shift towards self-employment in recent years.
But that’s not to say being self-employed is without its challenges and there will likely be some bumps in the road before your business is established, profitable and stable. You’ll need to build your brand and credibility, find clients and work hard to achieve growth and profitability.
There are also administrative challenges that employees don’t face such as record-keeping and managing your own tax affairs, but the first one you will encounter is to register as self-employed.
The process to register as self-employed differs depending on your business structure and in this post we’ll explore this for sole traders and limited companies.
When Must You Register as Self-Employed?
If you meet any of the below criteria then you must register as self-employed with HMRC.
- You earn £1,000 or more in a tax year from self-employment
- You need to prove you’re self-employed to access certain benefits such as tax-free childcare
- You want to pay voluntary class 2 National Insurance Contributions to help qualify for benefits or the state pension
- You need to register for the Construction Industry Scheme (CIS)
It’s important to register when you trigger any of these criteria to ensure that you’re taxed correctly and comply with HMRC regulations.
Sole Trader or Limited Company
The two most popular business structures for small business owners in the UK are sole trader and limited company. They differ in various ways, not least the complexity of the set up process to register as self-employed. The sole trader registration process is much simpler as are the admin requirements. As a sole trader you keep all profits after tax and have to complete an annual self-assessment tax return and have personal responsibility for business debts.
The process of setting up a limited company is more complex but incorporation has various benefits including financial protection thanks to limited liability and greater tax planning opportunities but you’ll also have to contend with increased admin obligations.
How to Register as a Self-Employed Sole Trader
Registering as a self-employed sole trader is quick, easy and free! You need to log in to your Government Gateway account and register for self-assessment by completing the required steps here. You’ll need to provide various details including your name, address, date of birth, National Insurance number and a description of what your business does.
When complete you can expect to receive your 10-digit Unique Taxpayer Reference (UTR) number within 15 working days then you’re good to go
You then have the responsibility of maintaining accurate records of your income and expenses and paying income tax and NICs through your annual self-assessment tax return. It’s also a good idea for sole traders to learn about their obligations in respect of Making Tax Digital because MTD for income tax will start to phase in for sole traders from April 2026.
How to Register as Self-Employed Through Your Own Limited Company
The situation is different for limited companies in terms of registration and also taxes. The process to register a limited company is more complex as the company must be registered as a legal entity with Companies House, known as incorporation.
You’ll firstly need to select a unique name for your company that adheres to Government guidelines. At least one Director and Shareholder must be appointed and persons with significant control identified as part of the incorporation process along with personal details. A registered office address must be confirmed and a Standard Industry Classification Code (SIC) needs to be selected to classify your main business activity.
Memorandums and Articles of Association need to be produced to set out why the business was formed as well as how it will be run. An incorporation fee is payable and Companies House will usually approve your business registration within 24hrs. You’ll then receive a Certificate of Incorporation and your business will be registered with HMRC for Corporation Tax.
Many self-employed people will engage a professional to handle this for them which saves them time and ensures that all legal requirements are met. With our expert company formation service, for just £160 inc VAT we’ll take care of the whole process for you and can usually have your limited company set up the very same day.
What Happens After You Register Your Limited Company?
Once your limited company is registered, you have various obligations that must be met:
- File annual company accounts and confirmation statement with Companies House
- File a Corporation Tax return and pay your tax bill
- Operate payroll if you receive a salary
- Submit a personal annual Self-Assessment tax return
Any salary that you receive from your company is taxed at source through Pay As You Earn (PAYE) but untaxed income from other sources as well as dividend income is taxed through your self-assessment tax return.
The Benefits of Working With an Accountant
Whether you’re forming a limited company or registering as a self-employed sole trader, working with an accountant from the start helps to ease the pressure, provides peace of mind that you’ll be compliant and gives your business the best chance of success.
