The £1,000 trading allowance, explained properly

The trading allowance is one of the tidiest reliefs in UK tax: up to £1,000 of gross trading income per tax year, tax-free, with no receipts, no expense records and — for many people — no tax return. It exists so that the person selling the odd item online or doing occasional paid favours does not have to run a miniature accounting system to stay legal.

It is also widely misunderstood, usually in one of two directions: people who could rely on it needlessly register for Self Assessment, and people who should be claiming real expenses give them up for a flat £1,000 that short-changes them. Here is how it actually works.

Full relief: £1,000 or less

If your total gross trading income for the tax year (6 April to 5 April) is £1,000 or less, the allowance applies automatically. You keep the money, pay no tax on it, and usually do not need to tell HMRC at all.

"Gross" is the word doing the work. It means everything you were paid before deducting any costs. If you sold £1,100 of hand-made goods that cost you £600 in materials, your gross trading income is £1,100 — over the limit — even though your profit is £500.

A few situations where you may still need, or want, to deal with HMRC even under £1,000:

• HMRC has already asked you to file a return (file it, and claim the allowance on it).
• You want to pay voluntary Class 2 National Insurance to protect your State Pension record.
• You made a loss and want to register it so it can reduce tax later — using the allowance instead would waste that loss.

Partial relief: over £1,000

Earn more than £1,000 gross and you will normally need to register for Self Assessment (the deadline is 5 October after the end of the tax year in which you started). You then face a genuine choice on your return:

• deduct the £1,000 allowance from your gross income, or
• deduct your actual allowable expenses —

but never both, and the choice covers the whole trade for that year. Claim the allowance and you cannot also claim any expenses or capital allowances for that trade.

When the allowance wins

The arithmetic is refreshingly simple: the allowance wins whenever your genuine expenses are less than £1,000. A tutor earning £4,000 a year whose only costs are £150 of books does far better deducting the flat £1,000 than the £150. Low-cost service businesses — tutoring, consulting on the side, dog-walking, digital sales with minimal overheads — are the natural home of this relief. There is also a quieter benefit: no expense records to keep for that trade.

When real expenses win

• Your expenses exceed £1,000. A maker spending £3,000 on materials would be donating £2,000 of deductions to HMRC by taking the allowance.
• You made a loss. The allowance cannot create or preserve a loss; claiming actual expenses can, and trading losses can reduce other tax. If your new venture is in its expensive early phase, think carefully before waving the allowance at it.
• You have capital purchases. Equipment claims sit with the expenses route, not the allowance.

You can switch approach year by year — allowance this year, expenses next — which is why keeping receipts even in a "probably allowance" year is wise. You cannot make the better choice without the records to compare, and the comparison itself takes minutes once the records exist.

The traps

• It is one allowance across all your trades combined, not £1,000 per venture. Three side hustles share a single £1,000.
• It cannot be used against income from your employer (or a close relative's business, your own company, or a partnership you are a partner in). It is for genuinely independent trading income.
• The property allowance is separate. There is a distinct £1,000 allowance for property income; rental income does not eat into your trading allowance, and vice versa.
• Gross means gross. Judge the £1,000 limit before expenses, always.
• Watch the growth curve. Side income has a habit of becoming real income. Once your gross takings climb, you inherit real obligations — Self Assessment, possibly payments on account, and in time Making Tax Digital, whose thresholds are also measured on gross income.

A note on marketplaces and platforms

Digital platforms now report sellers' income to HMRC, so "it was only a bit of eBay money" is visible in a way it never used to be. The trading allowance remains the correct, legal shelter for genuinely small trading income — but the days of small income being invisible are over, which makes knowing where you stand against the £1,000 line genuinely useful rather than academic.

Keeping the choice open

The only way to be sure whether the allowance or real expenses serves you better is to have the numbers for both. That is bookkeeping — light-touch bookkeeping, at this scale, but real. Our platform makes it nearly effortless: forward receipts and payments as they happen, and the records assemble themselves under our standing rule — AI drafts. AgentLedger validates. People approve. — so a person, not a guess, makes the allowance-versus-expenses call with you at year end.
