Trading allowance or expenses: which figure should you claim?

Gross trading income means receipts before expenses. For eligible income of £1,000 or less, full relief may apply, although circumstances can still require reporting or registration. More than £1,000 of receipts does not mean all of it becomes a tax bill: the taxable profit depends on the available deduction route.

The allowance is shared across eligible trading income. It is not £1,000 for each client, platform or separate job. Keep receipt records even where full relief means no tax is due.

Partial trading-allowance relief deducts up to £1,000, limited to the income. It replaces actual expenses and relevant other allowances. Do not deduct £1,000 and then subtract all the same expenses again.

Under the actual-expense route, only allowable business costs count. Personal drawings are not expenses. Mixed personal/business costs need an appropriate business portion, and capital items can have different treatment depending on the accounting method and asset. Use the official category guidance for a doubtful cost.

Assume all £2,000 costs are allowable, both routes are eligible, and the extra profit falls wholly in the 20% Income Tax band with no additional Class 4 or loan effect.

Actual costs give £200 more cash here. The allowance route does not make the £2,000 spent disappear from your bank account.

With £6,000 receipts and £200 allowable costs, the expense route gives £5,800 profit; the eligible allowance route gives £5,000. At an unchanged 20% marginal Income Tax rate, that £800 difference reduces tax by £160.

The money left is receipts less the actual £200 cash costs and the resulting tax. The £1,000 allowance is a tax deduction, not a cash payment from HMRC. Recalculate if a band, Class 4 threshold, student loan or Personal Allowance taper is involved.

The allowance cannot normally be used where the income comes from your employer, your spouse or civil partner’s employer, certain connected companies or partnerships. It does not apply to partnership trading income. Read the official conditions before selecting it.

The allowance cannot create a tax loss. If actual expenses exceed receipts, the available loss-relief choices can matter. Do not reduce the profit to zero and assume that settles the loss. Our ordinary positive-profit estimate directs that case to the appropriate loss guidance.

Write five figures: total gross receipts; eligible actual expenses; any separately computed capital or accounting adjustments; the eligible allowance deduction; and cash actually spent. Calculate profit under each allowed route, then apply the same other-income and tax-year assumptions.

Keep the underlying records and the reason for the chosen route. If you also have a job, add the resulting profit to the annual Income Tax calculation and credit PAYE tax separately. Use the calculator’s two deduction settings to compare rather than changing unrelated assumptions between results.
