The trading allowance can cover eligible receipts up to £1,000 or provide a deduction instead of actual expenses. Add relevant trades together and check exclusions. You cannot normally deduct both the allowance and the same trade’s actual expenses.
Two different uses of the £1,000 figure
- Registration / “do I need a return?” — Sole traders who earn more than £1,000 before reliefs generally must register for Self Assessment.
- Trading allowance on a return — If you already file, you can often deduct up to £1,000 from gross trading income instead of claiming actual expenses. You cannot claim both the full allowance and those expenses on the same income.
There is a separate £1,000 property allowance for property income. Trading and property each have their own £1,000 pot if you have both.
When you must still tell HMRC under £1,000
GOV.UK’s allowance guidance says you must register and declare the income if, for example, you:
- want to claim loss relief on a return
- want to pay voluntary Class 2 National Insurance
- want Tax-Free Childcare based on self-employment income
- want Maternity Allowance based on self-employment
Those are policy choices about benefits and National Insurance, not optional “nice to have” paperwork. If any apply, do not rely on the silent under-£1,000 path.
If you earn more than £1,000
You must register for Self Assessment (GOV.UK ties this to the 5 October date after the tax year for people who need to tell HMRC). On the return you can usually either:
- deduct the £1,000 trading allowance from gross income, or
- claim actual allowable expenses (and capital allowances where relevant) instead
Illustrative only: gross freelance income £3,200; receipts £400. Claiming the £1,000 allowance leaves £2,200 taxable trading income. Claiming £400 expenses leaves £2,800. The allowance wins here — but if expenses were £1,500, claiming expenses would usually be better. Work both ways before you tick a box.
What this means if you already file Self Assessment
Being in Self Assessment for another reason (employment benefits, property, high income) does not stop you using the trading allowance on trading income, where the rules allow it. It does mean you report the activity on the return rather than staying invisible under the small-income exemption.
Common mistake
Mixing up profit with gross income. The registration test and the allowance both start from gross trading receipts. A loss-making hustle with £2,000 of sales is still over £1,000 for “must register” purposes.

Compare deductions on the same receipts
Illustrative preparation example.
For an eligible trade with £1,600 receipts, compare the trading allowance with supported actual expenses. Keep the two calculations separate. Do not subtract both methods from the same income or assume the allowance is always the better choice.
Check: Which permitted method gives the appropriate result for this trade and year?
| Check | Practical action |
|---|---|
| Is this income eligible for the allowance? | Check exclusions and special relationships before choosing the simplified deduction. |
| Do actual allowable costs exceed the allowance? | Compare both permitted methods using supported figures and relevant capital costs. |
| Are there several trades? | Apply the allowance rules across the relevant income rather than duplicating the allowance per activity. |
Can the allowance create a trading loss?
No. If you need to claim a loss, check the actual-expense route and applicable loss-relief rules.
Is the threshold measured after expenses?
No. Start from gross trading income. A small profit does not make gross receipts above £1,000 disappear for registration purposes.
