Nobody has to let you start here.
There is no counter to visit before your first job, no fund to join, no number to obtain before you can send an invoice. You can film something this afternoon, invoice for it this evening, and be entirely legitimate.
That freedom is genuinely useful, and it is exactly what creates the problem eighteen months later.
What starting actually means
The trading allowance
There is an allowance for small amounts of trading income that do not have to be reported. If your creator income for a tax year stays under it, you have nothing to file.
It is the single most useful thing for someone testing whether this work suits them, and it is also where people get comfortable. The allowance is a level, not a permission, and the amount changes, so check the current figure at HMRC rather than repeating what a group told you last year.
Registering for Self Assessment
Once you go past the allowance, you register for Self Assessment. This is a registration with the tax authority, not the creation of a business, and it comes with a deadline that falls after the tax year in which you earned the money.
That gap is what confuses people. You earn first, you register afterwards, and both are correct.
The tax year does not start in January
This is the detail that catches every creator arriving from continental Europe, and it costs more than it should.
The UK tax year runs from April to April, not from January to December. So the income you earned last spring belongs to a tax year that ended before the calendar year did, and the deadlines that follow are calculated from April rather than from January.
Put the actual dates in a calendar the day you register. Every UK creator who has been fined has been fined for a date, not for a mistake in their figures.
The trap nobody warns you about
Here is the mechanism that makes a first tax bill feel like a punishment.
Once your bill passes a certain size, HMRC stops collecting only what you owe and starts collecting an advance on what you will owe next year. That advance is split into two instalments, and the first of them arrives at the same time as the bill for the year you have just finished.
The practical result: your first real bill is larger than the tax you actually owe for that year, because it contains both. Nothing has gone wrong. You are simply paying one year in arrears and half of the next one in advance, at the same moment.
It hits creators particularly hard because a good first proper year triggers it, and a good year is exactly when the money has already been spent.
The fix is unglamorous. Put a share of every payment into a separate account from the first invoice, ask your accountant for a percentage that fits your situation rather than guessing, and treat that account as though it belongs to someone else. Because for now, it does.
What you can deduct
Your taxable profit is income minus allowable expenses, so what counts as an expense decides what you actually pay.
What genuinely counts
Equipment used for the work, software subscriptions, professional insurance, an accountant, travel to a shoot, and a proportion of your phone and home costs corresponding to business use. There are simplified flat rate options for some of these, which are worth asking about because they save more time than they cost in accuracy.
What does not
Anything you would have bought anyway. Clothes you can wear outside a shoot, a phone used mostly personally, a trip that happened to include a client meeting. The test is not whether you can justify it to yourself, it is whether the expense exists because of the work.
Keep the receipt at the moment of purchase rather than reconstructing the year in January. That single habit is the difference between claiming what you are entitled to and quietly under claiming because you cannot prove it.
Sole trader or limited company
The UK is the market in this series where this question is genuinely live, because forming a company is cheap and common rather than exceptional.
| The question | As a sole trader | As a limited company |
|---|---|---|
| How you start | Register for Self Assessment, no formation needed | Incorporate, with filings from day one |
| Who is liable | You personally | The company, within limits |
| Admin weight | Light, one annual return | Heavier, annual accounts and more deadlines |
| How you get paid | The profit is yours | Salary and dividends, decided deliberately |
| What clients notice | Nothing, most do not care | Some larger clients prefer it |
| When it makes sense | Starting out, irregular income | Stable profit, or a client who requires it |
The honest answer is that most creators should start as a sole trader and revisit the question when their profit is high and predictable, or when a client insists. Forming a company early buys obligations before it buys benefits.
National Insurance
Alongside income tax there are National Insurance contributions for the self employed, calculated on your profits and collected through the same annual process.
They are not optional and they are not a detail: they are part of the number you should be setting aside. A creator who has budgeted for income tax alone has budgeted for roughly the wrong figure.
What actually keeps you out of trouble
Three habits, none of which take effort once started.
Separate the money the day it lands, not at the end of the quarter. Keep every invoice and every receipt in one place with consistent names, because the annual return is trivial when your records are ordered and miserable when they are not. And write down the deadlines the day you register, since none of them is a surprise and all of them are expensive late.
Do those three and the freedom that opened this article stays a genuine advantage rather than a bill you did not see coming.

Frequently asked questions
Do I need to register before my first job?
No. You can start immediately and register for Self Assessment once you pass the trading allowance, by the deadline that follows that tax year.
When does the UK tax year end?
In April, not in December. The deadlines that matter are calculated from that, which surprises most creators arriving from continental Europe.
Why is my first tax bill bigger than my tax?
Because it includes an advance on next year once your bill passes a certain size. You are paying one year in arrears and half of the next in advance at once.
Should I form a limited company?
Usually not at the start. Revisit it when your profit is high and predictable, or when a client requires it.
