The Simple Tax Relief That Can Cost Sole Traders Dear in 2026

For a freelancer, the £1,000 trading allowance looks like one of the simpler parts of the tax system. It is not. In 2026/27, the allowance remains a flat deduction that can be used instead of actual business expenses. The choice is optional, and making it without checking the numbers can raise taxable profit, waste relief and create avoidable record-keeping problems.

What the allowance does — and does not do

The trading allowance lets an individual deduct £1,000 from gross income from a trade, profession or vocation. It is available to sole traders and to some people with miscellaneous income, but it is not a general business tax relief. It is an alternative to deducting allowable expenses. A trader cannot claim the allowance and also deduct expenses or capital allowances for the same trade.

If gross trading income is £1,000 or less, the allowance can cover the income, and in many cases there is no need to report that trade through Self Assessment. That is the simple case. Once gross income exceeds £1,000, the trader must choose between the allowance and actual allowable expenses. The allowance cannot create a loss, and it does not reduce VAT liabilities. VAT-registered businesses must still keep VAT records and account for VAT in the normal way.

Why the simple option can cost more

The allowance is most valuable when allowable expenses are low. If a freelancer has £600 of expenses, a £1,000 deduction is better than £600. If expenses are £4,200, the allowance is worse by £3,200 of taxable profit. The trap is that the allowance is often described as a simplification, not as a comparison. In practice, it is a comparison.

The comparison should include capital allowances. A sole trader who buys equipment, a laptop or tools may be able to claim capital allowances instead of, or as well as, ordinary expenses. Using the trading allowance generally means giving up those deductions for that trade. That can be costly in a year with significant purchases.

Losses matter too. If actual expenses exceed income, the trader may have a trading loss that can be used against other income or carried forward, subject to the loss rules. The trading allowance cannot produce a loss. In a loss-making year, choosing the allowance can turn a deductible loss into taxable profit. That is the most serious version of the trap.

Worked example: low expenses

A freelance consultant has gross income of £18,000 and allowable expenses of £600.

Using the trading allowance: taxable profit is £17,000. Using actual expenses: taxable profit is £17,400.

The allowance reduces taxable profit by £400. At a basic rate of 20%, the income tax difference is £80 before Class 4 National Insurance. For a trader with low costs, the allowance is the better choice, and it reduces the expense records needed for that trade.

Worked example: higher expenses

The same consultant has gross income of £18,000 and allowable expenses of £4,200.

Using the trading allowance: taxable profit is £17,000. Using actual expenses: taxable profit is £13,800.

Actual expenses reduce taxable profit by £3,200 more than the allowance. At 20%, that is £640 more income tax if the allowance is claimed, before National Insurance. The allowance is not a tax cut here; it is a tax increase.

Worked example: loss and equipment

A sole trader has gross income of £9,000, ordinary allowable expenses of £10,500 and capital expenditure on equipment of £2,000 that qualifies for capital allowances.

Using actual expenses and capital allowances, the trade may show a loss. Using the trading allowance, the trader instead reports £8,000 of profit. The difference is not merely administrative. It can affect loss relief, Class 4 National Insurance and the amount of tax payable. A trader in this position should take advice before filing.

Record-keeping after the choice

If the trading allowance is claimed, the trader still needs records of income and evidence that the allowance applies. Detailed expense receipts for that trade are not needed for the allowance calculation, but other records must still be kept. These include records for VAT if registered, payroll records if there are employees, and records for any other income. If actual expenses are claimed, invoices, receipts, mileage logs and capital allowance records should be retained.

Self Assessment records generally need to be kept for at least five years after the 31 January submission deadline. A trader who switches between the allowance and actual expenses should keep a clear note of the choice made each year and the figures used.

A decision checklist for 2026

1. Add up gross trading income for the trade.
2. Add up allowable revenue expenses.
3. Add up capital allowances that would be available.
4. If expenses and capital allowances are below £1,000, the allowance is likely to be better.
5. If expenses and capital allowances are above £1,000, actual deductions are likely to be better.
6. If the trade has made a loss, check the loss rules before using the allowance.
7. If the business is VAT-registered, remember that the allowance does not replace VAT records.
8. If there are multiple trades, check how the allowance applies to each one.
9. If income is close to £1,000, confirm whether reporting is required.
10. If the answer is not clear, ask an accountant before the return is filed.

The adviser's view

The trading allowance is useful, but it is not a default. It rewards low-expense traders and penalises those with higher costs, losses or capital purchases. The correct approach is to calculate both routes each year. For many freelancers, that calculation takes minutes; for some, it prevents a costly error.

The allowance should be treated as a tax planning choice, not a bookkeeping shortcut. Used well, it simplifies the return. Used without thought, it can cost more than the records it saves.
