Guide

Allowance or expenses: how to choose

What the trading allowance is

The first £1,000 of trading income in a tax year is tax-free. If your income from selling (before costs) is £1,000 or less, you do not need to tell HMRC about it at all.

When your income is over £1,000

You choose: take £1,000 off your income as the allowance, or take off your actual expenses: the stock you sold, fees, postage, packaging, mileage and other costs. You cannot do both.

The simple rule

If your actual expenses are under £1,000, the allowance usually wins. Above £1,000, your actual expenses win. For resellers, the cost of the stock you sold alone often goes over £1,000.

Losses need actual expenses

If your costs are more than your income, only claiming actual expenses lets you record the loss. The allowance cannot create one.

Questions

Do I need to tell HMRC if I earn under £1,000?

Not if your total trading income (before expenses) from all your side hustles is £1,000 or less in the tax year and you have no other reason to file a Self Assessment return.

Is the £1,000 per side hustle?

No, it covers all your trading income together. There is a separate £1,000 allowance for property income.

Can I use the trading allowance and claim expenses?

No. You either deduct the £1,000 allowance or your actual allowable expenses, whichever you choose for that tax year.

Is the threshold going up to £3,000?

The government has said the income level at which you must file a Self Assessment return for trading income will rise to £3,000, but the £1,000 allowance itself is not changing. Check gov.uk for when it applies.
