The £3,000 Everyone Has Misread
Two numbers are circulating about side income, and most people have merged them into one.
The first is £1,000. That is the trading allowance, and it is the amount of gross trading income you can receive in a tax year without paying tax on it. It has been £1,000 since 6 April 2017.
The second is £3,000. That is a reporting threshold the government announced on 11 March 2025. When it arrives, people with gross trading income under £3,000 will not have to file a Self Assessment return. It is not a tax free amount. The trading allowance stays at £1,000, and tax will still be due on anything above it.
The gap between those two sentences is where the money goes. HMRC's own estimate is that the change takes around 300,000 people out of filing a tax return, and that around 90,000 of them will have no tax to pay at all. Do the subtraction. Roughly 210,000 people, seven in ten of the group being helped, will still owe tax. They will just pay it through a new online service instead of a return.
This guide covers what the allowance actually does, the two ways to claim it, the situations where claiming it is the wrong decision, who is shut out of it entirely, and what the £3,000 threshold will and will not change.
What the Trading Allowance Is
HMRC calls it the Trading and Miscellaneous Income Allowance. It gives you up to £1,000 of relief against two kinds of income:
- Trading income, meaning self-employment and casual work. Dog walking, babysitting, gardening, tutoring, freelance design, selling things you made or bought to resell.
- Miscellaneous income, meaning one off or casual receipts that are not quite a trade. Hiring out your drill, your driveway or your camera would sit here.
It is one allowance of £1,000 per person, not £1,000 per activity. If you tutor for £700 and sell prints for £600, your relevant income is £1,300 and you are over the line.
It is also separate from the £1,000 property allowance. If you have both kinds of income, you get £1,000 against each. The property allowance is covered in our guide to tax on rental income.
Gross Income, Not Profit
This is the single point that causes the most trouble, and it is worth being blunt about it.
The £1,000 test is applied to money in, before any costs come out. Not profit. Not what is left. Not what you transferred to your current account.
Almost every other figure in the tax system is measured on profit or on net income. Income tax bands, the personal allowance taper, Class 4 National Insurance, the child benefit charge, all of them look at a net number. The trading allowance does not, and people apply their income tax intuition to a turnover test.
Someone who sells £2,800 of handmade candles and spends £2,100 on wax, wicks and postage has made £700. They are not covered by the trading allowance, because their gross income was £2,800. They need to register for Self Assessment, and they need to do it whether or not any tax ends up being due.
The same logic catches content creators, where the gross figure includes the value of gifted products, and site owners, where it includes advertising revenue before any platform fee. We cover both in our guides on accounting for influencers and ad revenue websites.
The Two Ways to Claim It
Full relief: under £1,000
If your gross relevant income for the tax year is £1,000 or less, the income is treated as nil. There is nothing to report and nothing to pay. You do not need to register, you do not need to file, and you do not need to tell HMRC anything.
This happens automatically. There is no form and no election. If someone tells you to register to claim the trading allowance on £600 of income, they have misunderstood it.
Partial relief: over £1,000
If your gross income is more than £1,000, you can choose to deduct £1,000 instead of your actual expenses. You cannot do both. It is one or the other, and you decide each year.
The choice is simple arithmetic. If your real costs are less than £1,000, claim the allowance. If your real costs are more than £1,000, claim the costs.
Take an Etsy seller with £2,400 of sales and £700 of genuine costs.
| Claim actual expenses | Claim the trading allowance | |
|---|---|---|
| Gross income | £2,400 | £2,400 |
| Deduction | £700 | £1,000 |
| Taxable profit | £1,700 | £1,400 |
The allowance wins by £300 of taxable profit, worth £60 to a basic rate taxpayer. It also means no receipts to keep for that trade, which for a small side activity is worth something on its own.
Partial relief is an election, and you make it on your tax return. You still have to register and file. The allowance changes the number, not the obligation.
When Claiming It Is the Wrong Move
Here is the part that rarely gets said, and HMRC's own manual is clearer about it than most accountants are.
The trading allowance cannot create a loss. You can deduct up to the amount of your income and no further. If you claim it, your taxable profit is either positive or nil. It can never be negative.
That matters enormously in a first year. Consider a photographer who turns over £800 in year one and spends £2,600 on a body, a lens and a website.
If they claim the trading allowance, their gross income is under £1,000, so it is treated as nil. Clean and simple. It also throws away a £1,800 loss.
If they register instead and claim the actual expenses, they have an £1,800 trading loss. That loss can be carried forward against future profits of the same trade, and in the early years of a trade it can often be carried back against other income. On a £1,800 loss relieved at 20 percent, that is £360 of real money, and at 40 percent it is £720.
So the rule people repeat, that you do not need to do anything under £1,000, is true but incomplete. You do not have to do anything. Sometimes you very much should.
Our view: if you are starting something with real upfront costs, do not take the easy option in year one. Register, keep the records, claim the expenses, bank the loss. The admin is a couple of hours. The loss is worth hundreds.
Who Cannot Use It at All
The allowance is switched off completely, not reduced, if any of your relevant income in that tax year comes from:
- Your employer, or a company connected to your employer. You cannot leave employment on Friday and invoice the same business as a freelancer on Monday and shelter the first £1,000.
- A partnership you are a partner in. Partnership trading income is outside the allowance entirely.
- A close company that you, or someone connected to you, controls. This is the one that catches directors. If you run a limited company and also do a bit of consultancy work for it personally, that income cannot use the allowance.
Note the wording. If any part of your relevant income comes from one of these sources, you lose the allowance for that year across all of it, not just on the tainted slice. It is an all or nothing test.
This is straightforward anti-avoidance and it is aimed at exactly what it looks like: repackaging employment or company income as casual trading income to catch a free £1,000. If you are weighing up how to take money out of your own company, our guide on sole trader versus limited company is a better starting point.
What the £3,000 Threshold Actually Changes
Back to the two numbers.
The government announced on 11 March 2025 that the Self Assessment reporting threshold for trading income will rise from £1,000 to £3,000 of gross income, "within this parliament." As of September 2026 no start date has been formally set. Most commentary points at 2027/28 at the earliest, and the commitment runs to the end of the decade, so treat any specific date you read as a forecast rather than a fact.
When it does land, here is the actual effect.
| Gross trading income | Now | After the change |
|---|---|---|
| Under £1,000 | Nothing to do | Nothing to do |
| £1,000 to £3,000 | Register and file a tax return | No tax return, but tax still due on income above £1,000, paid through a new online service |
| Over £3,000 | Register and file a tax return | Register and file a tax return |
Read the middle row twice. The obligation to file goes. The tax does not.
Our take on this is mildly uncharitable. The announcement was headlined "300,000 people to be taken out of tax returns", and that is accurate. It is also the sort of accurate that is guaranteed to be misheard, because "taken out of tax returns" and "taken out of tax" sound identical to anyone who does not do this for a living. The queries we see rising, things like "trading allowance scrapped" and "£3,000 trading allowance", suggest the misreading is already widespread.
There is a simpler policy sitting right there. Raising the trading allowance itself from £1,000 to £3,000 would have removed the tax, removed the filing, removed the confusion, and required no new online service to be built. Instead the plan is to keep the allowance frozen and construct a second reporting channel alongside Self Assessment. That is more moving parts, not fewer.
And the freeze is the quiet part. The trading allowance has been £1,000 since April 2017. Nine years of inflation later, holding the same real value would put it somewhere near £1,350. Nobody campaigns about it because £1,000 sounds like a round, generous, recently set number. It is none of those things.
Selling Your Own Things Is Not Trading
A large share of the panic about side hustle tax comes from people clearing out a wardrobe on Vinted, and most of them owe nothing.
Selling your own used possessions is not trading. You are disposing of personal property, usually at a loss, and there is no income tax charge. The trading allowance does not even come into it, because there is no trade.
It becomes trading when you buy things in order to sell them, make things to sell, or sell with the frequency and organisation of a business. HMRC weighs this through what are known as the badges of trade: profit motive, how often you transact, whether you modify goods before selling, how you finance purchases, and how quickly you sell. Buying twenty pairs of trainers to flip is a trade. Selling twenty pairs of your own old trainers is a tidy up.
Two footnotes worth knowing. High value personal items can fall into capital gains tax rather than income tax, though the chattels rules exempt most items sold for £6,000 or less. And a car you owned and used personally is exempt from capital gains tax entirely.
Why platforms now report you
Since 1 January 2024, digital platforms have had to collect and report seller data to HMRC. The first reports covered calendar year 2024 and were due by 31 January 2025. A platform reports you if you made 30 or more sales, or received around €2,000 (roughly £1,700) or more, in a calendar year.
This is where the panic came from, and it needs putting in proportion. The tax rules did not change in 2024. The visibility did. Nothing became taxable that was not taxable before. What changed is that HMRC now receives the data automatically rather than having to go looking for it.
If you were genuinely selling old belongings, being reported means nothing. HMRC receiving a figure is not HMRC assessing a liability. If you were running a small trade above £1,000 and treating the threshold as theoretical, the calculation has changed, because the gap between what you declared and what HMRC already knows is now visible without an investigation.
National Insurance on Side Income
A point that saves people needless worry.
Class 4 National Insurance has its own floor of £12,570, and it is measured on self-employment profits alone, not on your total income. Someone earning £45,000 in a job with £1,400 of profit from an Etsy shop pays income tax on that £1,400 at their marginal rate, and no Class 4 at all.
Class 2 is no longer a mandatory weekly payment. If your profits are above the Small Profits Threshold of £7,105 for 2026/27, you are treated as having paid it and you receive the National Insurance credit for free. Below that, you can pay voluntarily at £3.65 a week to protect a qualifying year, which for someone with an otherwise incomplete record is often a very good buy. Our guide to National Insurance has the full picture.
Registering, and the Deadline That Is Not the Deadline
If you are over £1,000 gross, you must register for Self Assessment. The official deadline is 5 October following the end of the tax year in which the income arose. For income earned in 2026/27, which ends 5 April 2027, that is 5 October 2027.
Do not aim at it. Registration issues a UTR by post, and activating your online account needs a second code that also arrives by post. The practical lead time is weeks. People who register in late September regularly discover they cannot actually file when they want to.
Once you are filing, payments on account can appear if your bill passes £1,000, which is a different £1,000 and catches people who were not expecting to pay 150 percent of their first year's tax in one go.
Longer term, Making Tax Digital will pull sole traders with qualifying income over £50,000 into quarterly reporting from April 2026, dropping to £30,000 in April 2027 and £20,000 in April 2028. Side income is a long way below those thresholds today, but qualifying income is measured on gross turnover across all your self-employment and property, so a growing side trade plus a rental can reach it sooner than expected.
Worked Examples
The dog walker. £900 of income across the year, £120 of costs. Gross income is under £1,000, so it is treated as nil. No registration, no return, no tax. Nothing to do.
The tutor over the line. £2,800 of tuition income, £400 of costs. Claiming the allowance gives a taxable profit of £1,800, which beats claiming the £400. Tax at 20 percent is £360. When the £3,000 threshold arrives, this person will no longer file a return, and will still owe that £360. This is exactly the case the headlines obscure.
The start-up with kit. £800 of income, £2,600 of equipment. Do not claim the allowance. Register, claim the expenses, and carry forward an £1,800 loss worth £360 at basic rate or £720 at higher rate.
The director who cannot claim. £4,000 of consultancy income, of which £900 was invoiced to their own limited company. The connected party rule removes the allowance for the whole year, so the full £4,000 is assessed with actual expenses only.
The wardrobe clear out. £2,300 across 40 Vinted sales of personal clothing. Reported to HMRC by the platform, because it is over 30 transactions. Not a trade, not taxable, nothing to declare. Keep a note of what was sold in case anyone asks.
Our Honest Take
The gross income test is the whole problem. Nearly every mistake we see with this allowance traces back to someone testing their profit against £1,000 instead of their turnover. If you remember one thing, remember that the number HMRC is looking at is the one before costs.
Do not let a £1,000 allowance make a five year decision for you. Claiming it in a loss making first year is the most expensive small mistake in this area, and it is invisible, because nothing goes wrong. You simply never get the relief you were entitled to.
Treat the £3,000 threshold as an admin change and nothing more. If you have been budgeting for a tax free £3,000, stop. Budget for tax on everything above £1,000 and be pleasantly surprised if policy moves again.
The platform reporting rules are a good thing for honest sellers and a genuine problem for everyone else. If your records are straight, automatic reporting is neutral. If you have been under declaring, the arithmetic has already changed and the cheapest moment to fix it has already passed. Voluntary disclosure costs far less than being found.
Nine years is a long freeze. Our expectation is that the allowance itself stays at £1,000 for the foreseeable future and the government continues to solve this through reporting thresholds instead. Plan on that basis rather than on the assumption that a rise is coming.
How IAK Can Help
We act for a lot of people whose businesses started as something small on the side. Sole traders, content creators and affiliate site owners, consultants and freelancers across North London and Hertfordshire.
Practically, that means telling you whether you need to register at all, running the allowance against actual expenses so you claim whichever is worth more, making sure a loss making first year is treated as a loss rather than waved away, and setting up bookkeeping that takes minutes a month rather than a weekend in January. If the side income is growing, we will also tell you honestly when it is worth incorporating and when it is not.
If you are not sure whether what you are doing counts as a trade, that is a five minute conversation and a common one. Get in touch, or read more about our tax planning work.
