Trading allowance vs expenses: which should side hustlers use?
The £1,000 trading allowance and actual allowable expenses are two different ways UK side hustlers may reduce or simplify taxable trading income. The right choice depends on your gross income, your real costs and whether your activity needs to be reported to HMRC.

What is the £1,000 trading allowance?
The trading allowance can cover up to £1,000 of gross trading income in a tax year. Gross income means income before deducting expenses. It can apply to small amounts of trading, casual or miscellaneous income. This is useful for people with small side hustles, occasional freelance work, online selling, creator income, digital downloads or marketplace activity. If your annual gross trading income is £1,000 or less, you may not need to tell HMRC in many situations. However, there are exceptions, such as where you already need to complete a tax return or want to claim a loss. If your gross income is above £1,000, you may need to report the income and then decide whether to use actual allowable expenses or the trading allowance. The allowance is not based on profit. A side hustler with £1,200 of sales and £900 of costs is still above the £1,000 gross income level.
What are actual allowable expenses?
Actual allowable expenses are genuine business costs deducted from trading income to work out taxable profit. Examples can include platform fees, postage, packaging, materials, stock, software, payment processing fees, advertising, business-use internet, business-use phone costs, equipment, mileage and professional fees. The cost should be connected to the trade and supported by records. HMRC guidance explains that allowable expenses reduce taxable profit. If your turnover is high and your real costs are significant, actual expenses may give a more accurate result than using the trading allowance. For example, a reseller with stock costs, postage, packaging and platform fees may have much higher expenses than £1,000. A creator with camera equipment, editing software and platform fees may also need to compare the numbers carefully.
You usually choose one method for the same income
A common mistake is trying to claim both the trading allowance and actual expenses for the same income. In most cases, you choose one approach for that trading income. If you use the trading allowance, you do not also deduct actual expenses against the same income. If you use actual expenses, you calculate profit by deducting allowable costs from income. The better choice depends on the size of your costs. If actual expenses are lower than £1,000, the trading allowance may produce a lower taxable profit and less admin. If actual expenses are higher than £1,000, claiming actual expenses may be better. The choice can affect your tax estimate, record keeping and Self Assessment entries, so it is worth comparing both methods before filing.
Example: low-cost creator side hustle
Imagine a creator earns £1,800 from small sponsorships and affiliate links in a tax year. Their only costs are £150 of software and £50 of platform fees. Actual expenses total £200, so profit using actual expenses would be £1,600. If the creator uses the £1,000 trading allowance instead, the taxable amount before other tax calculations may be £800. In this simple example, the trading allowance may be more favourable. The creator should still keep basic records of income and understand why they chose the allowance. If their costs grow later, actual expenses may become better. This is why calculators are useful as planning tools but not a substitute for checking the final Self Assessment position.
Example: reseller with higher costs
Now imagine a reseller has £6,000 of marketplace sales. They spend £2,800 on stock, £500 on postage, £250 on packaging and £450 on platform fees. Actual expenses total £4,000, so profit using actual expenses would be £2,000. If the reseller used only the £1,000 trading allowance, the taxable amount before other calculations may be £5,000. In this example, actual expenses may be much more realistic. This is common for resellers, handmade sellers and physical product businesses because stock, materials, postage and platform costs can be substantial. Good records are essential because the tax result depends heavily on evidence of actual costs.
PAYE income and side hustle tax
If you have a PAYE job, your side hustle profit is usually considered alongside your other taxable income. Your employment tax code does not automatically cover separate trading profit. A side hustle that looks small can still create a tax bill if your salary already uses your Personal Allowance. Higher-rate taxpayers may see extra profit taxed at a higher marginal rate. Student loan repayments may also be affected depending on your plan and income. This is why a side hustle calculator should ask for main PAYE salary as well as side income and expenses. The trading allowance or actual expenses choice affects the profit figure, and your existing income affects how that profit may be taxed.
How to decide between trading allowance and expenses
Start with your gross trading income for the tax year. Then list your real business costs. If gross income is £1,000 or less, check whether you need to report it for any other reason. If gross income is above £1,000, compare the trading allowance with actual allowable expenses. If your real expenses are small, the trading allowance may be simpler. If your real expenses are large, actual expenses may be better. Also think about record keeping. Even if you use the allowance, you should still keep income records. If you use actual expenses, keep receipts, invoices, platform reports, bank records and notes for mixed-use costs. The decision should be based on evidence, not guesswork.
Several trades do not create several allowances
A person might tutor, sell templates and receive creator income in the same tax year. Do not assume each small activity receives a separate £1,000 trading allowance. Bring the relevant gross trading or miscellaneous income together and check HMRC conditions, while retaining activity-level records for profit and reporting. Salary and ordinary personal-item sales should not be added mechanically to the trading total, and property income has a separate property allowance concept. If activities involve partnerships, connected companies or income for which expenses are paid by somebody else, the simplification may not apply in the expected way. A clear schedule listing every source, why it is included or excluded and its gross amount is the safest starting point. The allowance is a reporting and profit-calculation rule, not a separate tax-free account attached to every app.
Why a loss can change the decision
The largest immediate deduction is not always the only consideration. If actual allowable expenses exceed trading income, the activity may have a tax loss, while using the trading allowance would not preserve the same actual-cost calculation. Loss relief has conditions, options and time limits, and HMRC may consider whether the activity is genuinely commercial and carried on with a view to profit. Keep complete evidence before making a claim and do not include private spending merely to create a loss. The interaction with PAYE income, other trades and future profits can be significant, so professional advice may be worthwhile. A calculator that simply chooses the lower provisional profit cannot decide which loss relief, if any, is available or whether the evidence supports it.
Make and document the comparison every tax year
Costs and income change, so last year choice need not remain best. Prepare two short calculations from the same gross-income total. Method one deducts only supportable actual expenses. Method two deducts the trading allowance where the conditions permit. Record which method gives the chosen taxable amount and why, then keep that worksheet with the return evidence. For example, with £4,500 of gross income and £700 of actual costs, the provisional figures are £3,800 using costs and £3,500 using the allowance. If actual costs rise to £1,600 the following year, actual-expense profit would be £2,900 and may be more favourable than a £3,500 allowance figure. Check mixed use, capital items and losses before finalising; a mechanical total can still include costs that need different treatment.
Records still matter when you use the allowance
The trading allowance reduces the need to list actual costs in the profit calculation, but it does not remove the need to know and evidence gross income. Keep invoices, platform statements, payout reports and a reconciliation to bank deposits. Preserve the worksheet showing which income streams were combined, any exclusions and why the allowance was selected. Actual cost receipts can still be commercially useful and may matter if you change method next year, face a refund or need to assess a loss. Where HMRC asks about the return, a clear income trail is stronger than saying the allowance meant no records were kept. Simplicity should come from the calculation method, not from losing the underlying evidence.
