The £1,000 Trading Allowance Explained (2025/26)

Last updated: May 2026 · 5 min read

The £1,000 trading allowance is the most useful relief for UK side hustlers. It's been around since April 2017, but with HMRC's new platform reporting rules pushing more people into Self Assessment, understanding exactly how it works is suddenly relevant to millions.

What it is, in one sentence

If your gross trading income across all sources is £1,000 or less in a tax year, you owe £0 tax and don't need to file Self Assessment for it.

What "trading income" means

Income from any of these counts toward the £1,000:

What does not count: rental income (use the separate £1,000 property allowance), employment income (already taxed via PAYE), savings interest, dividends.

How the choice works above £1,000

Earn over £1,000 gross? You have to file Self Assessment. On the return you choose, each year:

Pick whichever results in the lower taxable profit. The calculator above does this automatically.

When the allowance beats expenses

The £1,000 allowance is more generous than actual expenses when your real costs are below £1,000. Typical scenarios:

When actual expenses beat the allowance

Once your real costs exceed £1,000, switch. Common cases:

Common misunderstandings

"I earned £900, so I'm fine forever"

The £1,000 is per tax year (6 April to 5 April). New year, fresh allowance.

"I have two side hustles, so I get £2,000"

No. The £1,000 trading allowance is per person, not per business. Add all trading income together.

"I can use the trading allowance for rental income"

No. Property income uses the separate £1,000 property allowance. They're parallel, not overlapping.

"I made a loss, so the allowance doesn't apply"

The trading allowance is on gross income, not profit. If your gross was £800, you don't need to file regardless of expenses or losses. If your gross was £3,000 with £4,000 of expenses, you have a £1,000 trading loss, and you may want to file to claim it forward against future profits.

"I have to register because I crossed £1,000 once"

True, but only for that year. If next year's gross is back under £1,000, you can de-register.
