Self-employed from the first payout
You are self-employed from your first payout. Not from the day you register, and not from the day the money starts to feel like a real income. If you are earning from content work, HMRC treats you as trading, and the admin follows from that.
Most people put this off. It is also the part that gets expensive, because the penalties are automatic and they do not care why you were late.
This is general information, not tax advice. Your situation may have details that change the answer.
HMRC probably already knows
Since 1 January 2024, digital platforms have had to collect details about the people earning on them and report those details to HMRC.
What they collect includes your full name, the address where you normally live, your date of birth and your National Insurance number. What they report includes the total you earned on the platform over the calendar year, after the platform's own fees and commission, broken down by quarter. The platform sends it to HMRC by 31 January following the end of that calendar year.
You are entitled to a copy of what was reported about you. Ask for it if the platform has not sent it. It is useful when you file, and it tells you what HMRC is looking at.
Two things worth being clear about. A platform reporting you does not mean you owe tax. It means HMRC has a figure it can compare against what you declared. And the published exemptions from reporting are written around sales of goods, so they do not map neatly onto content work. Assume you are reported.
Registering
If your gross trading income for a tax year was more than £1,000, you need to register for Self Assessment. Gross means before expenses. It is the total that came in, not what you kept.
The deadline to tell HMRC is 5 October following the end of the tax year. For the tax year that ended 5 April 2026, that deadline was 5 October 2026. It has passed.
If you register late, you are not stuck. HMRC will send you a letter or email with a filing deadline of three months from the date on it. The tax itself is still due by 31 January. Where it bites is if you registered late and have not paid what you owe by 31 January, because then a failure to notify penalty can be charged on top, based on the amount left unpaid.
Register as soon as you work out you need to. You will need a Unique Taxpayer Reference before you can file, and that comes after registering, so leaving it late squeezes you at both ends.
The dates
For the tax year 6 April 2025 to 5 April 2026:
- 31 October 2026 was the paper filing deadline. That has gone.
- 31 January 2027 is the deadline to file online and to pay what you owe.
- 31 July is the second of the two payment on account dates, where those apply.
Payments on account catch people out. If your tax bill for the year was £1,000 or more, and you did not pay more than 80% of your tax outside Self Assessment, you have to make two advance payments towards next year's bill. Each one is half of what you owed last year. The practical effect is that your first 31 January can ask for more than you expected, because it combines last year's bill with the first instalment towards this year.
What you actually pay
Income tax applies to your profit, not your turnover. The personal allowance is £12,570 for both 2025/26 and 2026/27, so the first £12,570 of taxable income is untaxed. Above that, the basic rate is 20% up to £50,270, then 40%.
If you have a job as well, that salary uses up your personal allowance first. Your content work gets taxed on top of it. This is the single most common surprise.
National Insurance works separately. For 2026/27, Class 4 is 6% on profits between £12,570 and £50,270, then 2% above that. Class 2 is no longer something most self-employed people pay. If your profits are £7,105 or more, Class 2 is treated as paid, which protects your National Insurance record without you handing anything over.
Below £7,105 of profit, nothing is credited automatically. You can pay voluntary Class 2 at £3.65 a week instead. It matters, because National Insurance years build entitlement to the State Pension. Voluntary contributions do not always increase what you will get, so check your record before paying.
Nobody deducts any of this before you are paid. The money arrives whole and the bill comes later. Open a separate account and move a proportion of every payout into it on the day it lands. Our tax set-aside calculator gives you a rough monthly figure to work from.
Expenses, or the trading allowance
You get a choice, and it is one or the other.
You can claim the £1,000 trading allowance, which takes £1,000 off your gross income and requires no receipts. Or you can deduct your actual business expenses. You cannot do both against the same income.
If your real costs are under £1,000, the allowance is simpler and better. If they are higher, claim the expenses.
Expenses have to be genuinely for the business. Where something has mixed use, you claim the business proportion, not the whole thing. A phone used for work and for your personal life is apportioned. So is internet, and so is the part of your home you work in. Make the split something you could explain to someone who asked, because you may be asked.
Keep your records. Every figure on your return should trace back to a bank statement, an invoice or a receipt. If you are paid in dollars, pick a sensible basis for converting to sterling and use the same basis all year.
Your name, and who can see it
You register and file under your legal name. HMRC deals in legal identity, which is also why the details on your platform accounts should match it. Your working name is not what goes on a tax return.
That is less exposing than it sounds. Your tax affairs are confidential. HMRC does not publish them, and being a sole trader does not put your name or address on any public register.
Setting up a limited company does. Directors' names are published on the Companies House register, and anyone can search them. So is the service address a director gives, and so is the company's registered office address.
The addresses are manageable. Neither has to be your home. You can use an accountant's or a solicitor's address with their permission, or appoint an agent who provides one. If you have already registered your home address, you can ask Companies House to remove it. It has to be a physical UK address, so a PO Box will not work.
Your name being public is the part you cannot manage around. People sometimes incorporate because it sounds more private, and on that specific point it is the opposite. Our guide on staying anonymous covers separating your working identity from your legal one.
What changes in 2027
Two things are moving, and one is further along than the other.
Making Tax Digital for Income Tax is already live. From 6 April 2026 it applied to people whose gross self-employment and property income on their 2024/25 return was over £50,000. From 6 April 2027 it extends to those over £30,000, tested on the 2025/26 return you are filing now. From 6 April 2028 it reaches those over £20,000.
Note that the test is gross income before expenses, and that self-employment and property income are added together. Being in scope means keeping digital records in compatible software and sending quarterly updates, rather than filing once a year and forgetting about it in between. If the return you are about to file shows gross income over £30,000, you have until April 2027 to get set up.
The trading allowance is the less settled one. The Budget on 28 October 2026 announced a rise from £1,000 to £3,000 from 6 April 2027, with the Self Assessment reporting threshold rising in step. That has not been legislated yet, and the official guidance still says £1,000. Treat it as likely but not certain, and do not plan this year's filing around it.
If you are already behind
Some people reading this have been earning for a while and have never registered. That happens more than you would think, and it is fixable.
It is better to come forward than to wait. HMRC has platform data now, and the penalties for being found are worse than the penalties for putting your hand up. Late filing starts at £100, then £10 a day after three months up to £900, then 5% of the tax due or £300 at six months, and the same again at twelve. Late payment adds 5% of the unpaid tax at 30 days, six months and twelve months, with interest running on top.
Get an accountant for this. One who has dealt with creator income before, and who you do not have to explain the work to. It costs money and it is usually worth it. You will still need to produce the records, so start pulling your statements together now.
