The £1,000 Trading Allowance Explained for UK Sole Traders

The trading allowance is one of the most useful but least understood reliefs available to UK sole traders. It allows you to earn up to £1,000 from self-employment completely free of tax and National Insurance — with no need to register for Self Assessment, keep detailed records, or claim individual expenses.

If you earn more than £1,000, it can still reduce your tax bill. Here is everything you need to know.

What is the trading allowance?

The trading allowance is a £1,000 per year tax relief for individuals with income from self-employment, trading, or casual work. It was introduced in April 2017 and applies to each individual (not each business) per tax year.

There are two ways it can work for you:

1. Full exemption (income below £1,000) If your gross trading income — before any expenses — is £1,000 or less in a tax year, you are completely exempt. You do not need to register for Self Assessment, you pay no income tax, and you pay no National Insurance on that income.

2. Deduction instead of expenses (income above £1,000) If your gross income exceeds £1,000, you can choose to deduct the £1,000 trading allowance instead of your actual allowable expenses. This only makes sense if your actual expenses are below £1,000.

Who the trading allowance is designed for

The allowance was created for people with small amounts of informal income who were not registering for Self Assessment because the admin felt disproportionate to the money involved. Typical cases:

• Selling items occasionally on eBay, Vinted, or Facebook Marketplace
• Occasional freelance or casual work alongside employment
• Dog walking, tutoring, gardening, babysitting, or similar side activities
• Selling handmade goods or crafts
• Early-stage sole traders testing a business idea

It is also relevant for anyone starting a new business who may earn below £1,000 in their first few months.

The full exemption: how it works in practice

If your trading income is £1,000 or less in the tax year:

• You do not need to register for Self Assessment with HMRC
• You do not need to declare this income on a tax return
• You pay no income tax and no National Insurance on it
• You do not need to keep business expense records (though keeping basic income records is sensible)

This removes significant admin burden for people with small side incomes. A sole trader earning £800 from occasional freelance work alongside a full-time job pays nothing extra in tax and has no filing obligation.

Important caveat: if you have other reasons to file Self Assessment — for example, if your employed income is over £100,000, or you have untaxed investment income — you must still file a return, and the trading allowance is declared there.

When to use the allowance as a deduction (income over £1,000)

If your gross trading income exceeds £1,000, you have a choice each year:

Option A — Claim actual expenses: deduct your allowable business expenses from income to arrive at taxable profit.

Option B — Claim the trading allowance: deduct £1,000 from your gross income instead.

You will choose whichever results in lower taxable profit.

Scenario	Gross income	Actual expenses	Profit (actual)	Profit (allowance)	Better choice
A	£3,500	£200	£3,300	£2,500	Trading allowance
B	£3,500	£1,400	£2,100	£2,500	Actual expenses
C	£1,200	£800	£400	£200	Trading allowance

In scenario A, expenses are low — the trading allowance gives a larger deduction. In scenario B, actual expenses exceed £1,000 — claiming them is more efficient. In scenario C, the allowance wins again because expenses are below £1,000.

You make this choice each year when filing your Self Assessment return. You are not locked into one method permanently.

What the trading allowance does not cover

The trading allowance has clear boundaries:

• It does not apply to income from a partnership
• It does not apply to income paid by your own employer (for example, if your employer pays you for additional services outside your normal employment)
• It does not apply to income from letting rooms in your own home if you already claim the Rent a Room Relief scheme
• It does not cover both trading and property income — each has its own £1,000 allowance

You cannot combine the trading allowance with actual expenses. Once you elect to use the allowance, all expenses for that trade in that year are excluded.

The property allowance: a related relief

Alongside the trading allowance, HMRC offers a separate property allowance of £1,000 per year. This covers income from casual property letting — renting a parking space, subletting part of your home, or Airbnb income.

If you have both self-employment income and casual property income, you can potentially claim both allowances — sheltering £2,000 of income from tax entirely.

The trading allowance and Making Tax Digital

If your gross trading income is £1,000 or below, you are exempt from Making Tax Digital for Income Tax — you do not need to register, use MTD software, or make quarterly digital submissions.

If your income crosses £1,000 and you register for Self Assessment, normal MTD eligibility thresholds then apply based on your qualifying income:

• Over £50,000: mandatory from April 2026
• £30,000–£50,000: mandatory from April 2027
• Under £30,000: threshold not yet confirmed

The trading allowance itself can still be used in your MTD annual return — it is declared at the End of Period Statement stage when you finalise your tax position for the year.

How to claim the trading allowance

If your income is below £1,000: no action needed. You do not register for Self Assessment and the allowance is automatically applied by not declaring the income.

If your income is above £1,000 and you want to use the allowance instead of expenses: on your Self Assessment return (SA103 — the self-employment pages), select the trading allowance option rather than itemising expenses. HMRC's return walks you through this.

If you use accounting software: FreeAgent, Xero, and QuickBooks all support the trading allowance in their Self Assessment modules. You indicate you want to use the allowance rather than itemise expenses, and the software applies it to your return.

Summary

The trading allowance is simple but useful:

• Under £1,000 gross income: fully exempt — no registration, no tax, no filing required
• Over £1,000 gross income: claim the allowance instead of actual expenses if your expenses are below £1,000
• It applies per person, per tax year, and can be combined with the property allowance
• It does not apply to income from your own employer or a partnership

For most sole traders with meaningful trading income, the allowance becomes less relevant as expenses grow. But for those just starting out, running a small side business, or testing a new income stream, it removes a significant admin and tax burden for the first £1,000 earned.
