Do you need to register as self-employed for gig work?

You did a few months of delivery shifts, or some weekend driving, or a handful of freelance jobs between other things. The money landed. Now there is a nagging question: is this the kind of thing you are supposed to tell HMRC about, or is it too small to matter?

Here is the straight answer. If you earned more than £1,000 from gig or self-employed work in a single tax year, you need to register as self-employed and file a Self Assessment return. If you earned £1,000 or less, you usually do not. That one number, £1,000 of gross income, decides it for most people.

It is worth getting this right early, because the days of small gig income quietly flying under the radar are over. Since January 2024 the platforms you work through report what you earn straight to HMRC. The question was never really whether they would find out. It is whether you get ahead of it.

The short version

• If your gig income was more than £1,000 in a tax year, you must register as self-employed for Self Assessment. £1,000 or less, and you usually do not need to.
• The £1,000 is the trading allowance, and it is gross income: what you were paid before fuel, phone, insurance or any other costs come out.
• The deadline to register is 5 October after the end of the tax year you crossed the line. The tax year runs 6 April to 5 April.
• Having a normal job does not get you out of it. If your gig work on the side went over £1,000, you register for that, on top of your PAYE job.
• Since January 2024 platforms report your earnings to HMRC directly, so "they won't notice" is not a plan.

Do you actually need to register? Start with the £1,000 line

For most gig workers the test is simple. Add up everything you earned from self-employed work in the tax year, across every platform and side job. If the total is more than £1,000, you need to register as self-employed and send a Self Assessment tax return. If it is £1,000 or less, the trading allowance covers it and you usually do not have to tell HMRC at all.

Two things people get wrong. First, the £1,000 is gross, not profit. It is the money that hit your account before you take off fuel, your phone bill, or anything else. You can earn well under the personal allowance and still cross this line. Second, it is per tax year, not per job. For the detail on how the allowance works, see our guide to the trading allowance.

What counts as gig income

It is the total of all your self-employed work, not just your main app. Delivery riding, private hire driving, courier runs, freelance design, odd jobs found through a platform: it all adds into the same £1,000 test. If you drive for one app and deliver for another, you do not get a separate £1,000 for each. You add them together.

This catches people who think of each app as a separate little thing. To HMRC it is one self-employed you, with one total.

"But I already have a job"

A regular employed job does not exempt you. If you are taxed through PAYE on your main work and you also earned more than £1,000 from gig work on the side, you still need to register as self-employed for the gig part. Your employer handles tax on your wages. The gig income is on you to declare.

This is one of the most common ways people end up registering late, because the job makes them assume the tax side is already handled. It is not, for the self-employed bit. Our guide to gig work alongside employment walks through how the two fit together.

Why "HMRC won't notice" stopped being true in 2024

Since 1 January 2024, digital platforms in the UK have to collect and report what their workers and sellers earn, and send it to HMRC once a year. If you earn through a well-known app, assume HMRC can see a figure for you.

Now, a platform reporting your income does not by itself mean you owe tax. Whether you owe anything still comes down to the £1,000 line and your wider income. But it does mean that if you should have registered and did not, the mismatch is visible. The honest read is simple: decide your position from the rules, do not gamble on being invisible, because you are not.

How and when to register

If you are over the line, you register for Self Assessment as a sole trader, which is how most gig workers start. If you are weighing whether to set up a limited company instead, that is a separate decision, covered in sole trader vs limited company. HMRC sets you up, sends you a Unique Taxpayer Reference, and you file a return after the tax year ends.

The deadline to register is 5 October following the end of the tax year you went over £1,000. Miss it and you can face penalties even before any tax is due. That is the what and the when. For the full step-by-step, from registering to your UTR to your first return, follow our cornerstone guide to registering as self-employed.

Common questions

Do I need to register if I only did gig work for a few weeks?

It depends on the money, not the time. If those few weeks earned you more than £1,000 in total, yes, you register. If they earned £1,000 or less and you have no other reason to file, usually not.

Is the £1,000 before or after my costs?

Before. The £1,000 trading allowance is measured on gross income, the full amount you were paid, not your profit after fuel and other costs. You can be barely breaking even and still be over the line.

I earned under £1,000. Do I need to do anything?

Usually not. If your total self-employed income for the tax year was £1,000 or less, the trading allowance covers it and you do not need to tell HMRC, unless you have another reason to file a return. You do not need to register just because a platform reported you.

I have a full-time job and drive at weekends. Do I still register?

Yes, if the weekend driving earned you more than £1,000 in the tax year. Your job is taxed through PAYE, but the gig income is separate and you declare it yourself through Self Assessment.

What happens if I do not register?

HMRC can charge penalties and interest, and because the platforms now report your earnings, an unregistered worker who should have signed up is easier to spot. If you have missed a deadline, registering and sorting it out is always better than waiting to be contacted.

The bottom line

For most gig workers it comes down to one number. Over £1,000 of gig income in a tax year and you register as self-employed by 5 October. £1,000 or less and you usually do not. Do not let a side job drift into a tax problem because nobody told you where the line was, and do not bank on HMRC not noticing, because since 2024 the platforms tell them. If you are over the line, our guide to registering as self-employed takes you through the whole process, from your first registration to your first return.

This is general guidance, not personal tax advice. Your own circumstances decide what you need to do, so check your Self Assessment position with HMRC or an adviser if anything here does not match your situation.
