The £1,000 trading allowance and £1,000 property allowance are two of the most under-used tax breaks in the UK system. Together they let casual side-hustlers and small-scale landlords earn up to £2,000 of gross income with no Self Assessment filing at all, and they let higher earners deduct a flat £1,000 against gross receipts instead of tracking real expenses.
But they also have traps. Claim the allowance on the wrong income source and you can end up paying tax on income that real expenses would have wiped out. Mix them up with rent-a-room relief and you may end up either filing unnecessarily or missing a much bigger relief. And from April 2026, Making Tax Digital changes how the trading allowance interacts with the £20,000 MTD threshold for self-employment and property combined.
This guide covers when each allowance applies, the decision framework for claiming the allowance versus deducting actual expenses, and three specific traps that catch most casual side-hustlers.
The Two Allowances: A Quick Map
The UK has two separate flat allowances introduced in April 2017:
- Trading allowance: £1,000 of gross income from self-employment, casual services, or “miscellaneous” trading (eBay flipping, OnlyFans, freelance gigs, ride-hail driving, content creation, etc.)
- Property allowance: £1,000 of gross income from UK property (a spare-room let, a parking space rented out, occasional Airbnb hosting, a paddock licensed for grazing, etc.)
Both allowances apply to gross receipts before any expenses. They are individual allowances (each spouse or partner gets their own), separate from the personal allowance, and you can claim both in the same tax year if you have both types of income.
Crucially, the two allowances do not offset each other and they do not combine. You cannot earn £1,500 of trading income and £500 of property income and use the leftover £500 of the property allowance to cover the trading overage.
When You Do Not Need to File Self Assessment at All
If your gross trading income for the year is £1,000 or less and you have no other Self Assessment trigger (e.g., you are not self-employed full-time, you have no untaxed savings or dividend income above the allowances, you are not a higher earner caught by the High Income Child Benefit Charge), you do not need to register for Self Assessment or file a return at all. The trading allowance is applied automatically.
The same rule applies to property income: gross UK property receipts of £1,000 or less, no other SA trigger, no filing required.
This is genuinely a “do nothing” zone. You do not need to register, do not need to declare the income, and do not need to keep records to prove the income was below £1,000 — though keeping a rough log is sensible if you are anywhere near the threshold.
From April 2026, Making Tax Digital for Income Tax (MTD ITSA) changes some of the surrounding admin for people with self-employment plus property income totalling more than £20,000 — but it does not change the £1,000 trading allowance carve-out itself. If your gross side income is genuinely under £1,000, MTD does not apply to you. For more on how MTD reporting interacts with these thresholds, see our Making Tax Digital income tax 2026 guide.
If you are uncertain whether you have an SA trigger at all, run your circumstances through the Self Assessment checker before assuming you are clear.
When You Do File, but the Allowance Still Saves You Money
If your gross trading or property income is over £1,000, you must file Self Assessment (or be eligible to register and file). At the point of filing, you choose either:
- Claim the £1,000 allowance as a flat deduction against gross receipts, with no other expenses deductible against that income, or
- Deduct your actual allowable expenses in the normal way
You cannot do both on the same income source. The choice is per source per year (you can claim the allowance for trading and deduct actuals for property in the same return, for example).
The trick is to pick the option that gives the bigger deduction.
Allowance vs Actual Expenses: Decision Framework
The decision is simple arithmetic:
- If your actual allowable expenses are less than £1,000, claim the allowance. You get £1,000 of deduction with no record-keeping.
- If your actual allowable expenses are more than £1,000, deduct actuals. You get the full benefit of your real costs.
The break-even point is at £1,000 of expenses. Below that, the allowance wins; above that, actuals win.
There is one subtle factor that pushes the threshold higher in practice: record-keeping cost and audit risk. If your real expenses are £1,100 — only £100 above the allowance — you might still prefer the allowance, because the extra £100 of deduction saves £20-£45 of tax (at 20% or 40% or 45% marginal rate) but costs you an hour of receipt-keeping and exposes you to enquiry over what counts as an allowable business expense. Most people only switch to actuals once their real expenses are clearly £200-£300 above the allowance.
Worked Example A: Allowance Wins
Priya runs a small Etsy shop selling hand-drawn cards. In 2025-26:
- Gross sales: £2,500
- Actual allowable expenses (card stock, ink, postage, Etsy fees): £400
Option 1 — Trading allowance: £2,500 − £1,000 = £1,500 taxable profit
Option 2 — Actual expenses: £2,500 − £400 = £2,100 taxable profit
Priya should claim the allowance. It gives her £600 more in deductions than actuals. At a 20% basic-rate marginal, she saves £120 of tax. At a 40% higher-rate marginal (if she has another job), she saves £240.
She still needs to register for Self Assessment (gross over £1,000) and report the income, but she ticks the “trading allowance” box on the return and skips expense receipts entirely.
For a full picture of her tax — including Class 2 and Class 4 National Insurance if her side-hustle profit pushes her over the relevant thresholds — Priya can run the numbers through the Self-Employment Tax Calculator.
Worked Example B: Actuals Win
Tom drives part-time for a private hire app while studying. In 2025-26:
- Gross fares: £8,000
- Actual allowable expenses (fuel, insurance contribution, vehicle costs, phone, app commission): £3,500
Option 1 — Trading allowance: £8,000 − £1,000 = £7,000 taxable profit
Option 2 — Actual expenses: £8,000 − £3,500 = £4,500 taxable profit
Tom should deduct actuals. The £3,500 of real expenses gives him £2,500 more in deductions than the flat allowance. At a 20% marginal rate that is £500 of tax saved; at 40% it is £1,000.
Tom must keep receipts and a mileage log to support the actual expenses on enquiry. But the tax saving easily justifies the admin.
This is a useful sanity check: as a rough rule, if your expenses are running above 20-25% of gross receipts, actuals will usually win. Below 10%, the allowance almost certainly wins. The 10-20% zone is the genuine grey area.
What You Cannot Do With the Allowance
Three rules trip up most people:
1. You cannot claim the allowance AND deduct expenses on the same income source. It is one or the other, per source, per year. People who report gross income minus actuals minus the allowance are making a mistake that HMRC enquiries pick up on.
2. You cannot use the trading allowance if you receive trading income from a connected party — e.g., a partnership, your own limited company, or an employer you used to work for. The rule blocks people from re-routing what is really salary or business profit through a personal allowance. If your “side income” comes from your own Ltd, the trading allowance does not apply.
3. You cannot use the property allowance if you have claimed deductible finance costs or mortgage interest relief on the property. Since the 2017-2020 transition replaced mortgage interest deduction with a 20% basic-rate credit, this rule means that if you are claiming the mortgage-interest tax credit (Section 24), you cannot also claim the property allowance on that property. It is one or the other.
The trading allowance has a parallel restriction for partnerships: you cannot claim it on partnership share income, only on standalone trading income.
Rent a Room Scheme: Do Not Confuse It
The Rent a Room scheme is a separate, much bigger relief: £7,500 of tax-free rental income (or £3,750 each if you let jointly) on a furnished room in your main home.
It is entirely separate from the £1,000 property allowance, with different rules and a much higher cap. If you are letting a furnished room in the home you live in — even via short-term platforms like Airbnb, depending on circumstances — Rent a Room is almost always the relief to use, not the property allowance.
Where it gets confusing: if you have a spare room let (Rent a Room income, £7,500 cap) and a parking space rented separately (general property income, £1,000 cap), the two reliefs run in parallel on different income streams.
People sometimes “claim the property allowance” on what is actually Rent a Room income and pay tax they could have avoided. Always check Rent a Room first if the income comes from your main home; only fall back on the property allowance for income that does not qualify (parking, paddocks, second properties).
What Counts as “Trading”?
The trading allowance is broadly drawn. It covers any income with the hallmarks of trading — repeated transactions for profit, providing a service for payment, selling goods you have made or sourced for resale, content monetisation. Specifically, HMRC accepts that the following are typically “trading” for the £1,000 allowance:
- eBay, Depop, Vinted resale of items you have bought to sell on (note: personal items you sold below cost are not trading at all and have no tax)
- OnlyFans, Patreon, Substack, YouTube AdSense and other content-creator income
- Etsy, Folksy, eBay sales of items you made yourself
- Ride-hail, food delivery, courier work (Uber, Deliveroo, Stuart, Just Eat)
- Freelance services (design, writing, tutoring, photography)
- Pet-sitting, dog-walking, occasional childcare
- Casual labour and odd jobs (Airtasker-style platforms, helping friends for cash)
Activities that are explicitly not trading: investment income (interest, dividends, capital gains), employment income (salary, including PAYE side jobs), pension income, rental income (separate property allowance), and one-off sales of personal items below their original cost.
If you are a content creator hovering around the threshold, the Self-Employment Tax Calculator will let you model the tax bill at different gross income levels.

FAQs
Can my partner and I both claim the £1,000 trading allowance on a side business we run together?
If the business is genuinely a partnership (you both contribute work and share profits and risk), the trading allowance does not apply to partnership share income at all — it is excluded by statute. If you each run separate side activities (one of you sells crafts, the other sells flipped electronics), you each get your own £1,000 trading allowance against your own gross receipts. The distinction comes down to whether HMRC would view the activity as one joint trade or two separate individual trades.
I sold £1,200 of unwanted personal items on eBay over the year. Do I owe tax?
Probably not, and the trading allowance does not really apply because it is not trading. HMRC’s “trading” test asks whether you are buying items to sell on for profit, or making items to sell. Selling personal possessions you originally bought for your own use — even if the total exceeds £1,000 — is not trading and is generally outside Income Tax altogether. (Capital Gains Tax can apply to disposals of single chattels worth more than £6,000, but rarely bites on routine eBay clear-outs.) If you are flipping items you bought specifically to resell, that is trading, and the £1,000 allowance is the relevant relief.
Does the £1,000 trading allowance reduce the income that counts toward the £20,000 MTD threshold from April 2026?
The £20,000 threshold for Making Tax Digital for Income Tax is based on gross income from self-employment plus property, before the allowance. So if you have £15,000 gross self-employment and £8,000 gross property income, your combined gross is £23,000 — over the threshold — and MTD reporting applies, even though after both £1,000 allowances your taxable figures are lower. The allowance reduces your tax bill but does not exempt you from the MTD reporting obligation once gross income crosses the threshold.
