Understanding Self Assessment is essential to help you meet your tax obligations and follow HMRC rules. If you want to manage your financial responsibilities better as a freelancer, keep reading to learn about registering as self-employed, what self-assessment means, claiming expenses, paying taxes, and those all important deadlines. Let’s simplify Self Assessment for freelancers in the UK.

Registering as self-employed

The first step to managing your freelance career is to register as self-employed. You should register for Self Assessment and Class 2 National Insurance contributions by 5th October in the second year of your business. So if you started your business in June 2024, you will need to register for Self Assessment and NI by the 5th October 2025. Failure to do this can result in a fine. If you have missed the deadline, register as quickly as possible and comply with Self Assessment requirements.

To register, visit the HMRC website and complete the online registration form. When registering with HMRC, follow these steps to ensure compliance. Here’s an overview of the process:

1. Choose your business structure

Start by choosing the most suitable business structure for your venture. Being self-employed simply indicates how you pay your taxes, you still need to identify a business structure that is right for you. You can choose from a number of structures including sole trader or establishing a limited company, each offering distinct advantages. Conduct thorough research to determine which option aligns best with your business goals.

2. Notify HMRC of self-employment

Once you’ve decided on your structure, inform HMRC that you are self-employed. This can easily be done through the official gov.uk website.

3. Register for Self Assessment

After notifying HMRC, you must register for self-assessment. This tax return is crucial as it allows HMRC to calculate your tax liabilities based on your earnings.

4. Receive your unique taxpayer reference (UTR)

Following your self-assessment registration, HMRC will post a Unique Taxpayer Reference (UTR) within 10 days. It is important to keep this reference secure, as you will need it to submit your tax returns.

5. Set up a government gateway account

With your UTR number, you can create a government gateway account, enabling you to submit your tax returns online efficiently.

Following these steps ensures that your business is appropriately registered and compliant with HMRC regulations.

What does Self Assessment for freelancers mean?

Self Assessment is a system in the UK that allows individuals to report their income and pay taxes directly to HMRC. For freelancers, this means you need to calculate your own tax liability and file an annual tax return.

As a freelancer, keep accurate records of your earnings and expenses throughout the year. This includes income from clients or projects and any allowable expenses related to your freelance work.
Self Assessment also requires you to declare any other sources of income outside of freelancing, like investments or rental properties. By completing a Self Assessment tax return (SATR) each year, you fulfil your obligations and stay on top of your tax responsibilities.

What information do freelancers need to include for SATR?

As a freelancer in the UK, knowing what information to include is essential when filling out your Self Assessment for HMRC. When completing your tax return, report your income and expenses from self-employment. This includes any freelance work or consultancy fees earned during the tax year.
You also need to report any other sources of income, like rental properties or investments. Keep accurate records of your earnings and expenses throughout the year so you can quickly provide this information to HMRC. Being organised with your financial documents will make the Self Assessment process more manageable and help you comply with tax regulations.

What expenses can I claim as a freelancer?

As a freelancer, claiming specific expenses can significantly reduce the taxable income you report on your Self Assessment tax return. These expenses are essential for running your business effectively and can make a real difference in the amount of tax you owe.
Common expenses you can claim include office supplies, professional subscriptions, travel costs related to business, marketing and advertising expenses, website hosting fees, and a portion of your home utility bills if you work from home. Keeping meticulous records of these expenses throughout the year is crucial. This preparation will save you time and minimise stress during tax season.
By claiming allowable expenses, you can effectively lower your taxable income and keep more of your hard-earned money in your pocket. Remember, all expenses you claim must be legitimate and directly linked to your freelance work.

Deadlines for Self Assessment tax return for freelancers

Awareness of Self Assessment tax return deadlines is vital for freelancers. Missing these deadlines can lead to penalties, which you can easily avoid with proper planning. Keep these key dates in mind:

1. 5th October

If this marks your first time registering as self-employed or starting a freelance business, notify HMRC by this date, the year following your business setup, to stay compliant.

2. 31st October

This is the deadline for submitting your paper Self Assessment tax return. Make sure it is posted in plenty of time.

3. 31st January

This is your deadline for submitting your online Self Assessment tax return. Be proactive and gather all your financial information well ahead of time to sidestep any last-minute rush. Ensure you also pay any outstanding tax liability from the previous year by this date too.

4. Throughout the year

Mark critical upcoming dates, such as payments on account due on 31st July and balancing payments due on the following 31st January.
By staying organised and keeping these key deadlines in sight, you can confidently fulfil your obligations as a freelancer regarding taxes.
