Registering and your first 30 days
Starting self-employed work can come with a lot of questions. Do I need to register? What records should I keep? When do I need to think about tax?
This guide takes you through the essentials, from your first freelance job to the simple habits worth putting in place during your first month.
Before you register
Being told that a job is “freelance”, being asked to invoice, or working on short-term contracts does not automatically mean that you should register as self-employed.
Before registering because of a particular job, make sure you understand how that job is actually engaging you.
You can be employed for some work and self-employed for other work at the same time. Your tax status can also differ from your status for employment rights.
FMTW NOTE
Not sure whether this job is really self-employed?
Start with our How is this job engaging you? guide. It will help you work through how you are being paid, your tax status and your employment-rights status.
Do this before registering simply because an engager has told you to invoice or described you as “freelance”.
IMPORTANT INFORMATION
What does “registering” mean in this guide?
This guide is primarily for freelancers starting out as sole traders, which is the simplest business structure and the route many people use when they first become self-employed.
Registering as a sole trader means registering for Self Assessment with HMRC. It does not mean setting up a limited company.
If you work through your own limited company, different tax and reporting rules can apply and this guide will not cover everything you need to do.
Already registered as self-employed?
That does not automatically make every job you take self-employed.
A particular engagement may still be treated as employment for tax, and you may have employee or worker rights depending on the actual working arrangement.
Do you actually need to register yet?
Not necessarily.
You can start working as a sole trader without registering with HMRC straight away.
For most people starting out, the key figure to watch is your gross trading income for the tax year. A tax year runs from 6 April to 5 April.
£1,000 or less
If your total gross trading income for the tax year is £1,000 or less, you will usually not need to register for Self Assessment just because of that self-employed income.
There are some exceptions, which we explain below.
More than £1,000
If your total gross trading income for the tax year is more than £1,000, you normally need to register for Self Assessment as a sole trader.
You can also choose to register earlier if you know you are likely to go over the threshold.
It is £1,000 of income, not £1,000 of profit.
“Gross trading income” means the money your self-employed work brings in before you take off expenses or allowances.
And it is not £1,000 per job, production or client. You need to look at your relevant trading income across the whole tax year.
Example: several small freelance jobs
A stage manager earns £450 from one short freelance project and £700 from another during the same tax year.
They have £300 of allowable business expenses.
The figure that matters for the £1,000 test is still £1,150, not £850, because the test looks at gross trading income before expenses.
They have gone over £1,000, so they would normally need to register for Self Assessment.
Going over £1,000 does not mean you suddenly owe tax on everything
The £1,000 figure helps determine whether you need to tell HMRC about your trading income. It is not the same thing as calculating your final tax bill.
How much tax you actually pay will depend on your taxable income and circumstances. If you qualify, you may be able to use the £1,000 trading allowance or claim allowable business expenses instead.
You cannot normally use the trading allowance and also deduct your actual business expenses from the same trading income. We will come back to this later in the guide.
Why might I register even if I earn £1,000 or less?
The £1,000 rule is a useful starting point, but there are circumstances where you may still need or choose to complete Self Assessment.
For example, this can include if you:
- want to claim tax relief for a trading loss;
- want to make voluntary Class 2 National Insurance contributions to help qualify for certain benefits;
- need your self-employed income taken into account for Tax-Free Childcare; or
- want to claim Maternity Allowance based on your self-employment.
There are also situations where the trading allowance cannot be used, so check rather than assuming the £1,000 rule applies to you.
OFFICIAL GUIDANCE
Check whether you need to send a tax return
GOV.UK has an official checker that can help you work out whether you need to send a Self Assessment tax return.
IMPORTANT INFORMATION
VAT registration is separate from Self Assessment
Registering as a sole trader for Self Assessment does not register you for VAT. VAT has its own rules and is based on taxable turnover, not profit.
At the time this page was reviewed, September 2026, you would normally need to register for VAT if either:
-
your total taxable turnover for the previous 12 months goes over £90,000; or
-
you expect your taxable turnover to go over £90,000 in the next 30 days.
The 12-month test is rolling. It does not reset at the end of the tax year, so check the total regularly if your turnover is approaching the threshold.
Taxable turnover generally means the total value of the goods and services you sell that are not exempt from VAT or outside the scope of VAT.
If you register late, VAT may still be due on taxable sales and services from the date you should have registered, even if your invoices did not include VAT. A penalty may also apply. This can create a serious cash-flow problem.
FMTW is not a tax adviser. This is general information and signposting, not personal tax or financial advice. VAT rules can depend on what you supply and your circumstances. Check the current HMRC guidance and seek qualified advice if you are unsure.
Your first 7 days
Once you start genuinely self-employed work, you do not need to have everything figured out immediately.
You do not automatically need an accountant, expensive accounting software or a business bank account in your first week.
But there are a few simple things worth doing from the very beginning. Getting into these habits now can save you a lot of detective work later.
Start keeping records from day one.
HMRC requires sole traders to keep appropriate records of their business income and expenses.
Even if your trading income ends up being £1,000 or less and you do not need to tell HMRC about it, you should still keep a record of the income you received.
Your first-week checklist
- Make a note of when you started.
Record the date you began trading and the kind of freelance work you are doing. Keep the details of your first jobs, clients or engagers too. - Start recording money coming in.
Keep a simple record of who paid you, what the payment was for, when you received it and how much you received. - Start recording business spending.
Keep track of money you spend on your freelance work. Record what you bought or paid for, when you paid it, how much it cost and what it was for. - Create somewhere for your paperwork.
Keep copies of invoices, receipts, bank records and other evidence relating to your freelance income and spending. A simple, organised digital folder is a perfectly good place to start. - Make your business money easy to identify.
Try to keep your freelance transactions easy to distinguish from everyday personal spending. This will make record keeping much easier later. - Start thinking about tax.
Consider putting some of each freelance payment aside so that money is available when a future tax bill becomes due.
Your system can be simple
You do not necessarily need specialist accounting software when you start out.
For a straightforward sole-trader business, your records might begin as a spreadsheet showing your income and expenses, alongside an organised folder containing invoices and receipts.
Whatever system you use, your records need to be accurate and allow you to identify your business transactions.
One thing to know: cash basis accounting is now the standard method for most sole traders. Under cash basis, you generally record income when you actually receive the money and expenses when you actually pay them.
IMPORTANT INFORMATION
Receiving Universal Credit?
Universal Credit has its own rules for reporting self-employed income and expenses. Do not wait for your Self Assessment tax return before checking what you need to report.
If you receive Universal Credit, check the rules and any reporting tasks in your Universal Credit account when you start self-employed work.
Your first 30 days
There is nothing magical about day 30. Think of your first month as a useful point to stop, check that the basics are working and sort out anything you have been putting off.
You do not need to have built the perfect freelance business. A few simple systems are enough.
By the end of your first month
- Check your income so far.
Keep an eye on your total gross trading income for the tax year. If it is becoming clear that you will need to register for Self Assessment, you can start that process. - Be ready to invoice.
If your freelance work is paid by invoice, create a simple reusable template and make sure you know what information needs to go on it. We have a separate invoice guide to help with this. - Get familiar with expenses.
You do not need to memorise the tax rules. Just start learning which business costs may be allowable, keep your evidence and remember that something being related to your work does not automatically make it tax deductible. - Give yourself a regular admin slot.
A short weekly routine for updating records, filing receipts, checking invoices and putting money aside for tax can stop freelance admin becoming a much bigger job later.
Keep it proportionate
Your freelance setup can grow with you. You do not need to have everything figured out in your first month.
Good records, a way to get paid and an understanding of what you need to do next are a very good start.
Put these dates in your diary
Self Assessment does not mean constant HMRC deadlines. For most new sole traders, there are just a few key dates to know.
The deadlines come after the end of the tax year in which you earned the income.
5 October
Tell HMRC if you need to complete Self Assessment.
If you need to complete a tax return for the previous tax year and have not already done so, this is normally the deadline for registering.
31 January
Submit your online tax return and pay what you owe.
This is normally the deadline for submitting your online Self Assessment return and paying any tax due for the previous tax year.
What does that look like in practice?
If you start self-employed work in August 2026 and need to complete Self Assessment for the 2026/27 tax year:
- The tax year ends on 5 April 2027.
- You would normally need to register by 5 October 2027.
- Your online tax return and payment would normally be due by 31 January 2028.
OFFICIAL GUIDANCE
Check the current Self Assessment deadlines
Deadlines and individual circumstances can vary. Use the current GOV.UK guidance to check when you need to register, submit a return and pay HMRC.
IMPORTANT INFORMATION
Why your first Self Assessment payment may be higher than expected
When you complete your first Self Assessment return, HMRC may ask you to pay both the amount due for the tax year just ended and an advance payment towards your next bill. These advance payments are called payments on account.
If payments on account apply and you have not made them before, your first payment deadline may include:
- the full amount due for the tax year just ended; and
- a first payment on account towards the following year, usually calculated using the previous year’s bill.
A second payment on account is normally due by 31 July.
A simplified example
If HMRC calculates that you owe £2,000 for the tax year just ended and payments on account apply, you might be asked to pay:
- £3,000 by 31 January: the £2,000 you owe, plus a £1,000 first payment on account; and
- a further £1,000 by 31 July: your second payment on account.
This is sometimes described as paying “18 months of tax at once”. It is more accurate to think of it as paying one year’s actual bill plus an advance payment towards the following year.
Payments on account do not apply to everyone. Whether you need to make them will depend on your circumstances, including the amount you owe through Self Assessment and how much tax has already been collected elsewhere, such as through PAYE. Your Self Assessment statement or HMRC account will show whether payments on account apply to you.
FMTW is not a tax adviser. This is a simplified explanation for general information and signposting, not personal tax or financial advice. Check the amounts shown in your HMRC account and use the current HMRC guidance. If you are unsure, ask HMRC, TaxAid, a union tax specialist or a qualified adviser about your own circumstances.
A note about Making Tax Digital
Making Tax Digital for Income Tax (MTD) is a new way that some sole traders and landlords have to keep records and report information to HMRC.
It does not apply to every freelancer. If you are just starting out, you will not normally need to start using MTD immediately.
OFFICIAL GUIDANCE
Making Tax Digital for Income Tax is being introduced in stages. Whether you need to use it depends on your qualifying income in an earlier tax year.
- If your qualifying income was over £50,000 in 2024/25, you need to use Making Tax Digital from 6 April 2026.
- If your qualifying income is over £30,000 in 2025/26, you will need to use it from 6 April 2027.
- If your qualifying income is over £20,000 in 2026/27, you will need to use it from 6 April 2028.
Qualifying income generally means your total income from self-employment and property before expenses are deducted. HMRC uses your Self Assessment information to work out whether you are above the relevant threshold.

What changes if MTD applies to me?
You will need to use compatible software to keep digital records and send updates to HMRC every three months.
These quarterly updates are not four separate tax returns. You still submit a tax return for the year and pay any tax due by the usual 31 January deadline.
If your income grows, check the current rules to find out when MTD will apply to you.
