Who Are Self Employed and What Does It Mean?
When you work for yourself and are not paid via Pay As You Earn (PAYE) like an employee, then you are considered self-employed. Self-employed individuals operate as freelancers, independent contractors or sole traders.
A self-employed individual bears the responsibility for their business’s failures and successes. Moreover, they manage operating costs, tax affairs and client relationships. Self-employed individuals do not work under a contract of employment and control how they complete their work.
Why It Is Crucial to Register as Self Employed?
Before explaining how to register as self employed, let’s discuss why registration is necessary.
It is essential to register as self-employed once you start trading. In the UK, it is a legal requirement to declare your income to HM Revenue and Customs (HMRC) and pay the correct income tax through self-assessment. HMRC needs to know how much you are earning to calculate the correct amount of tax.
Who Needs to Register as Self Employed?
You are self-employed when you have full responsibility for the profit and loss of your business. You need to register as self employed if your income exceeds £1,000 from self-employment. If its is less than £1,000, you don’t need to register as self-employed.
HMRC charge the appropriate amount of tax once you are registered. It considers you self-employed if:
- You have multiple customers at the same time
- You can hire employees at your own expense
- You control when and how to work
- You can make a profit and loss, and you are responsible for the profit and loss
- You provide the tools you need for work

How to Register as Self Employed in UK
Registering as self-employed depends on the business structure you choose. You can be a limited company or a sole trader. Registration of each business model differs regarding administration, tax and liability.
This section will explain how to register as self employed. Let’s explain it step by step.
Step 1: Check whether you need to register
First of all, you should check if you are qualified as self-employed. HMRC helps you determine whether you should be classified as self-employed or employed.
You are classified as self-employed if you run the business yourself, decide how and where to work, and you are responsible for profits and losses.
Step 2: Government account creation
Once classified as self-employed by HMRC, you need to go to the gov.uk website. Visit the HMRC’s official website and sign up for a Government Gateway Account. This gives you access to HMRC’s services and guidelines for tax purposes.
Note: If you are wondering how to register as self employed online, go to the HMRC website and get online services.
Step 3: Fill in the registration form
After creating your account, you will receive a user ID. You should provide your email address and new password so that only you can log into your account. There is an online self employed registration form that requires you to provide your personal information, including name, address, NI number and start date of your business.
Step 4: Submit the form
Once you enter the required information, submit it to HMRC. HMRC processes it and sends you confirmation.
If you want paper-based registration, call the HMRC helpline. They will guide you with the paper documentation. Prepare documents, print out the form and fill it, attach the documents and send it to HMRC by post.
While filing the form, look for the right form. There are different forms if you are a partnership (Form SA400) and if you have joined a partnership (Form SA401).
Step 5: Get your Unique Taxpayer Reference (UTR)
Once you submit your form, HMRC will send you the 10-digit UTR. This UTR is then used on all subsequent tax payments, so it is important to keep it safe.
In addition, HMRC will enrol you for self-assessment. This means you are officially HMRC self employed.
Now you know how to register as self employed, let’s discuss when you need to register as self-employed.
When to Register As Self Employed?
According to HMRC, self-employed individuals must register for self-assessment and class 2 NI. You must register as self-employed by the due date, which is 5 October following the end of your first tax year.
For instance, if you started your business on 20 August 2024, you must register by 5 October 2025. If you don’t, HMRC may charge a fine. Therefore, it is best to register as self-employed as quickly as possible.

How to Register for Self Assessment?
A person can register for self-assessment even if they are not self-employed. Registration for self-assessment occurs at the same time as registration for self-employment. Create a Government Gateway account and start the process.
You register when your income exceeds £1,000. However, even if your income is below £1,000, you can voluntarily register for self-assessment and claim business expenses. This allows you to declare a trading loss or pay voluntary class 2 NI to protect your benefit entitlements.
Registering lets you pay voluntary Class 2 National Insurance contributions, which ensures that the year counts toward your State Pension and other benefits.
What Tax Do You Pay If You Are Self-Employed?
Being self-employed means you need to meet HMRC tax regulations by paying the right amount of tax. So, the self-employed must understand the small business tax they need to pay. As a self-employed, you need to pay:
Income tax
Complete your self-assessment tax return each year so that HMRC can calculate how much income tax you need to pay on your income. HMRC calculates the tax after deducting all legitimate business expenses.
There are two methods of filing your self-assessment tax return. For filing a paper application, you must file a tax return by 31 October. If you are filing online, the deadline is 31 January.
National Insurance Contributions (NIC)
Self-employed individuals also need to pay NIC tax on their income to fund state benefits. However, not every self-employed are obliged to pay NIC tax. If your profits from business are more than £12,570, you need to pay class 4 NI.
Moreover, you don’t need to pay class 2 NI tax if your income is £6,845 or more because your contributions are treated as having been paid to protect your National Insurance record.
Value Added Tax (VAT)
You need to register for VAT if your business turnover exceeds the £90,000 threshold in a rolling 12-month period. This means you need to charge your customers VAT and submit it to HMRC.
In addition to that, you can claim VAT on allowable business expenses to reduce your tax bill.
Register As a Sole Trader
Sole traders often wonder how to register as self employed and whether registering as self-employed is easy or not.
It is easy to register as a sole trader. There is no registration fee, and there is less paperwork. You do everything yourself.
Additionally, you do not need to register with Companies House, and your business information remains private. However, there is no legal distinction between business and private assets. You have unlimited liability for business debts.
Register as a Partnership
When registering as a partnership, you don’t have to register with Companies House like a limited company. Instead, you need to submit tax returns and individual paperwork just like sole traders.
In addition to your self-assessment tax returns, the nominated partner has to submit information on the company’s behalf. Also, they must register the partnership and take responsibility for keeping the company’s books and filing tax returns.
Register As Limited Company
Registering as a limited company differs from registering as a sole trader or a partnership. A Limited Company must register for Corporation Tax with HMRC. Also, it costs you a registration fee. The cost is different for online (£50) and paper applications (£71).
Online registration takes 24 hours, while via post, it may take longer (7-14 working days). If you need to register on the same day, you need to pay extra money (£78).
Moreover, you need to register with Companies House, and once registered, you will get a certificate that confirms the existence of your company.

- You set the work method and schedules yourself. Only you decide when and where to work.
