The £1,000 trading allowance explained (UK, 2026)

The trading allowance is the single most misunderstood number in side-hustle tax. It is not a tax-free wage. It is a choice, and for a lot of taskers it is the wrong choice by the second year.

What it actually is

You can claim a flat £1,000 against your gross self-employed income in a tax year (6 April to 5 April). If your gross income is £1,000 or less, the allowance wipes it out completely: no registration, no return, nothing to tell HMRC.

Two things about that sentence do most of the damage.

"Gross" means before anything comes off. Not after the platform's fee. Not after fuel, materials or parking. If a customer paid £1,100 for a job and you spent £400 on materials and fees, your gross income is £1,100 and you are over the line. The figure a platform reports to HMRC is this gross figure too, which is why so many people open their January statement and think it looks wrong.

It is per person, not per platform or per trade. One allowance covers everything you do self-employed. Cleaning on one app, assembly on another, and selling a few things you made are added together against the same £1,000.

There is a separate £1,000 property allowance for rental income. They do not share a pot, and you can use both.

The two methods, and why you must pick one

Once you are over £1,000 you register for Self Assessment and choose, for each tax year:

• The trading allowance method. Deduct a flat £1,000 from gross income. You claim no expenses at all.
• The actual expenses method. Deduct what you really spent, mileage, tools, materials, platform fees, insurance. You claim no allowance.

You cannot use both on the same trade, and you cannot claim capital allowances (for a van, say) while using the allowance. You can switch year to year, so the arithmetic is worth redoing each January.

The rule of thumb is simply: if your real, provable costs are under £1,000, use the allowance.

Worked example one: £900 of task income

You did a handful of weekend jobs. Gross income £900. You spent about £220 on fuel and a drill bit.

• Gross is under £1,000, so full relief applies automatically.
• You do not need to register, file, or tell HMRC anything.
• You should still keep a note of what you earned. If HMRC asks, "it was under a grand" is a claim you need to be able to evidence.

One exception worth knowing: if your costs were higher than your income, you bought £1,400 of tools to earn £900, you may want to register anyway and claim the loss, which can be set against other income or carried forward. That is a real decision with real money in it, and worth an accountant's half hour.

Worked example two: £2,500 of task income

Gross income £2,500. Real costs: £250 mileage, £180 materials, £120 insurance, and platform fees (deductible, see our fees). Say £600 all in.

Method	Calculation	Taxable profit
Trading allowance	£2,500 − £1,000	£1,500
Actual expenses	£2,500 − £600	£1,900

The allowance wins by £400 of profit. At the basic rate of income tax that is roughly £80 saved, plus a little National Insurance, for less paperwork. If this is your pattern, take the allowance and stop worrying about receipts for a year.

Note the trap: the allowance saved you money and you still had to register and file, because gross income was over £1,000. The allowance never removes the filing obligation. It only reduces the taxable figure.

Worked example three: £12,000 of task income

Now you have a van and you are doing this three days a week. Gross income £12,000. Real costs:

Cost	Amount
Mileage, 8,000 business miles at 45p	£3,600
Materials and consumables	£1,400
Tools bought this year	£700
Platform and payment fees	£1,100
Public liability insurance	£140
Phone, business share	£180
Total	£7,120

Method	Calculation	Taxable profit
Trading allowance	£12,000 − £1,000	£11,000
Actual expenses	£12,000 − £7,120	£4,880

Actual expenses win by £6,120 of profit. At the basic rate that is well over a thousand pounds of tax, before National Insurance. The mileage line alone is more than three times the allowance.

This is the year the allowance stops being the right answer, and most people notice a year late.

When to stop using the allowance

1. Your costs pass £1,000. For anyone driving to jobs, that is roughly 2,300 business miles. A single busy month.
2. You buy something big. A van, a trailer, a pressure washer. Capital allowances are unavailable under the allowance method.
3. You want to claim a loss. Start-up years often run at a loss; the allowance cannot create one.
4. You have more than one trade with very different cost profiles, you must apply the same method across your self-employment, so run the numbers together.

One counter-argument, honestly: claiming the allowance shows a higher declared profit, and mortgage lenders work off declared profit on your SA302. Paying slightly more tax to show a bigger profit is a legitimate trade-off if you are applying for a mortgage in the next two years. Do it deliberately, not by accident.

Where you cannot use it

The allowance is blocked against money paid to you by your own employer, by your spouse's or civil partner's employer, by a partnership you are a partner in, or by a close company you or a connected person control. It exists for genuine small trading income, not for repackaging a salary.

The £3,000 figure you may have seen

HMRC's own side-hustle campaign pages refer to a simpler online reporting service for people with trading income between £1,000 and £3,000, described as coming "when it's live". As at 5 September 2026 it was not live. Two things to be clear about: it is a change to how you report, not a new tax-free amount, and until it exists the £1,000 trigger and the 5 October registration deadline still apply. Check gov.uk for the current position before assuming it covers you.
