The £1,000 trading allowance is the most useful and most misunderstood number in UK side hustle tax. Most people have heard of it.
Fewer people understand exactly how it is measured, when it applies, what it covers, and what happens when you use it in your tax return compared to claiming actual expenses.
This guide covers everything: what the allowance is, what counts as gross income for measuring it, when using the allowance is better than claiming expenses, and the specific situations where the allowance does not apply at all. It is the reference article you should read before any other tax article on this site.
What is the £ 1,000 Trading Allowance?
Every UK individual receives a £1,000 trading allowance per tax year. The tax year runs from 6 April to 5 April.
The allowance works as follows:
If your total gross trading income across all self-employed activities combined stays below £1,000 in the tax year, you owe no income tax on it, no National Insurance, and are not required to register for Self Assessment or tell HMRC anything about it.
If your total gross trading income exceeds £1,000 in the tax year, you must register for Self Assessment and report your income.
You then choose one of two methods for calculating your taxable profit: claim the £1,000 trading allowance as a flat deduction, or claim your actual allowable expenses.
That is the complete summary. The rest of this guide explains the details that matter.
What Counts as Gross Income?
This is the most important detail in the entire topic, and the one most commonly misunderstood.
Gross Income is What Your Customers Paid You
The trading allowance is measured against gross income, the total amount paid to you before any deductions, costs, or platform fees.
It is not:
- Your profit after expenses
- Your bank deposits after platform fees
- What you actually kept
It is: every pound paid to you by customers, clients, or platforms for goods or services you provided.
Practical Examples
You sell on Etsy, and buyers paid a total of £1,150. Etsy deducted £160 in fees and paid you £990. Your gross income for HMRC purposes is £1,150 above the threshold.
You do private tutoring and invoice a total of £900. Your gross income is £900 below the threshold.
You do Vinted reselling and received £800 in buyer payments, plus £320 from dog walking clients. Your combined gross income is £1,120 above the threshold, even though neither activity alone crossed £1,000.
You do Amazon Flex and received £2,200 in block payments from Amazon. Your gross income is £2,200, regardless of what you spend on fuel and insurance.
Why This Matters So Much?
Many people believe the threshold is measured by profit. It is not. Someone who earned £1,200 gross but spent £900 on materials has a profit of £300, but their gross income crossed the £1,000 threshold, and they are required to register for Self Assessment.
The test for whether you must register is gross income. The test for what tax you owe is profit.
How the Allowance Appears on Your Self-Assessment Return?
Once you have registered and are filing a Self Assessment return, the trading allowance appears as Option A on the self-employment pages (SA103).
Option A: Trading Allowance
You claim a flat £1,000 deduction from your gross income. No receipts required. No expense breakdown needed.
Taxable profit = Gross income − £1,000
Option B: Actual Expenses
You claim your real, documented allowable expenses. Receipts and records are required for each expense claimed.
Taxable profit = Gross income − Total allowable expenses
You choose which option to use each tax year, independently for each self-employment activity. You cannot combine both in the same year for the same activity. You can change the method from one tax year to the next.
Trading Allowance vs Actual Expenses: How to Decide?
The decision is purely mathematical. Run both calculations and use whichever gives the lower taxable profit.
Use the Trading Allowance (Option a) When:
Your actual allowable expenses are less than £1,000. In this case, the allowance gives a larger deduction than your real costs, producing a lower taxable profit.
Your actual expenses are under £1,000, and you want simplified record-keeping. No receipts needed for Option A, just your gross income figure.
Use Actual Expenses (Option B) When:
Your actual allowable expenses exceed £1,000. The larger deduction reduces your taxable profit further than the flat allowance.
You have significant material costs, platform fees, mileage, or equipment costs. Common for delivery drivers, makers who buy materials, and service providers with travel costs.
The Crossover Point
If your expenses are exactly £1,000, both options produce the same taxable profit. Above £1,000 in real expenses, Option B wins. Below £1,000, Option A wins.
Important: The Allowance is All-or-nothing
You cannot claim the £1,000 trading allowance AND also claim some of your actual expenses on top. It is one or the other.
If you claim the trading allowance, you claim the flat £1,000 and nothing else. If you claim actual expenses, you claim your documented costs and the trading allowance is not used.
Worked Examples: Both Options Compared
Example 1: Vinted Reseller
Annual gross sales: £2,800
Stock purchased: £680
Packaging and postage costs: £210
Total actual expenses: £890
Option A trading allowance:
Taxable profit: £2,800 − £1,000 = £1,800
Option B actual expenses:
Taxable profit: £2,800 − £890 = £1,910
Decision: Use Option A (trading allowance). It saves £110 in taxable profit.
Example 2: Amazon Flex Driver
Annual gross block payments: £6,400
Fuel: £1,200
H&R insurance: £1,800
Vehicle maintenance allocation: £400
Total actual expenses: £3,400
Option A trading allowance:
Taxable profit: £6,400 − £1,000 = £5,400
Option B actual expenses:
Taxable profit: £6,400 − £3,400 = £3,000
Decision: Use Option B (actual expenses). It saves £2,400 in taxable profit, a significant difference, particularly for a higher-rate taxpayer.
Example 3: Freelance Graphic Designer
Annual gross invoices: £4,500
Software subscriptions: £180
Professional membership: £120
Total actual expenses: £300
Option A trading allowance:
Taxable profit: £4,500 − £1,000 = £3,500
Option B actual expenses:
Taxable profit: £4,500 − £300 = £4,200
Decision: Use Option A (trading allowance). Despite having genuine business expenses, the flat allowance gives a much lower taxable profit.
The Key Lesson From These Examples
High-cost businesses (delivery, materials-heavy making) should almost always use actual expenses. Low-cost service businesses (tutoring, freelancing, online writing) almost always benefit more from the trading allowance.
When the Trading Allowance Does Not Apply?
There are specific situations where the £1,000 trading allowance cannot be used. Knowing these prevents errors on your tax return.
Partnership Income
If you share a business with a partner and your share of the gross income is part of a formal trading partnership, the trading allowance is not available. Partnership income is reported differently and the allowance does not apply to it.
Income Already Covered by the Property Allowance
There is a separate £1,000 property income allowance for rental income. If you receive both trading income and property income, each has its own separate £1,000 allowance. You do not add them together into one £2,000 pot; they remain separate.
Employment Income
The trading allowance applies only to self-employed trading income. Your PAYE salary is not trading income, and the allowance is irrelevant to it.
Income From an Employer or Former Employer
If you receive payments from someone who is also your employer (or former employer) for services performed, HMRC may not permit the trading allowance on those payments.
This is a specific anti-avoidance provision designed to prevent salary being reclassified as trading income to use the allowance.
The Allowance and Multiple Side Hustles
This is one of the most common areas of confusion.
One Allowance Per Person, Not Per Activity
You have a single £1,000 trading allowance across all your self-employed activities. It is not £1,000 per business or per platform.
If you tutor, sell on Etsy, and do occasional freelance writing, all three activities’ gross income is added together and measured against a single £1,000 allowance.
How the Decision Works Across Multiple Activities?
When you file your return, you apply the trading allowance to all self-employment income combined, or you claim actual expenses across all activities.
You cannot use the trading allowance for your Etsy business and actual expenses for your tutoring in the same year.
In practice, most people with multiple small side hustles whose total gross income is not far above £1,000 benefit from the flat trading allowance because their combined actual expenses rarely exceed it.
People with one high-cost activity (like delivery driving) alongside lower-cost activities should calculate both options with all activities combined.
The £3,000 Threshold Change: What Has and Has Not Happened?
You may have seen references to the trading allowance increasing to £3,000. The situation in June 2026 is as follows.
The Government Has Announced an Intention
The government announced a policy intention to raise the threshold above which a full Self Assessment return is required from £1,000 to £3,000.
Under this change, earners between £1,000 and £3,000 would not need a full Self Assessment return but would use a simpler online reporting tool.
This Has Not Been Legislated
As confirmed by ICAEW and multiple professional accountancy bodies, this change had not received Royal Assent as of the date of this article. It has no legal force. The current operative threshold remains £1,000.
Do Not Rely on the £3,000 Figure for 2025/26 or 2026/27
If you earned between £1,000 and £3,000 gross in 2025/26, you must register for Self Assessment under current law. The 5 October 2026 deadline applies.
Filing based on the assumption that the new threshold is already in force is a compliance risk with genuine penalty consequences.
When the change is legislated and implemented, HMRC will announce it clearly on gov.uk. Until then, the £1,000 threshold is the operative rule.
Frequently Asked Questions
Does the £1,000 trading allowance reset every year?
Yes. You receive a fresh £1,000 allowance each tax year (6 April to 5 April). Crossing the threshold in one year does not affect your allowance in the next.
However, once you are registered for Self Assessment, you remain registered and must file a return each year until HMRC confirms you can deregister, even if your income falls below £1,000.
Can I use the trading allowance if I am already employed full-time?
Yes. The trading allowance covers self-employed trading income regardless of your employment status. Your salary is PAYE income and is entirely separate. A full-time employee earning £35,000 can still claim the £1,000 trading allowance on their side hustle income.
If I use the trading allowance, do I still have to keep records?
HMRC strongly recommends keeping records regardless of which method you use. Even if you claim the flat trading allowance and do not need expense receipts, you still need to be able to confirm your gross income figure if HMRC ever queries it. A simple spreadsheet or bank statement breakdown is sufficient.
Can a student use the trading allowance?
Yes. Every UK tax resident individual has a £1,000 trading allowance, including students. There is no minimum age or income floor.
If my Etsy income is £900 and my tutoring income is £200, do I need to register?
Your combined gross trading income is £1,100 above the £1,000 threshold. Yes, you must register for Self Assessment. The fact that neither activity individually exceeded £1,000 is irrelevant. The allowance is per person, not per activity.
