Trading Allowance for Sole Traders: Claim It or Use Actual Expenses?

What Is the Trading Allowance?

The trading allowance is a £1,000 tax-free amount that sole traders and freelancers can use against their self-employment income each tax year. Introduced in April 2017, it is designed to simplify the tax position for people with small amounts of trading income, side hustles, or casual freelance work.

If your gross self-employment income is £1,000 or less, you do not need to report it to HMRC at all. If your income exceeds £1,000, you have a choice: deduct the flat £1,000 allowance, or deduct your actual allowable business expenses instead. You cannot do both.

When the Trading Allowance Works in Your Favour

The trading allowance is most useful when your actual business expenses are low. Consider these scenarios where claiming the allowance makes clear sense:

• You earn £8,000 from freelance work and your genuine expenses total only £400. Claiming the £1,000 allowance saves you more tax than itemising expenses.
• Your work is primarily service-based, such as consulting or writing, with minimal costs beyond your time.
• You want to simplify your record-keeping and avoid tracking receipts for small purchases.

In these cases, the allowance gives you a straightforward deduction without any need to justify individual costs to HMRC.

When Actual Expenses Are the Better Choice

If your genuine business expenses exceed £1,000, you should always claim actual costs instead. Common deductible expenses for sole traders include:

• Equipment, tools, and software subscriptions
• Use of home as office (calculated using HMRC's flat rate or actual costs)
• Professional subscriptions and training directly related to your trade
• Travel and mileage for business journeys
• Accountancy and professional fees

For example, if you are a freelance photographer with £3,500 in equipment and software costs, claiming only £1,000 would leave £2,500 of legitimate deductions on the table. That could easily cost you an extra £500 to £1,000 in Income Tax and National Insurance contributions depending on your tax band.

How to Claim the Trading Allowance on Your Self Assessment Return

If you already complete a Self Assessment tax return, claiming the trading allowance is straightforward. On the self-employment pages, you simply enter your gross income and indicate that you are using the trading allowance rather than actual expenses. HMRC will apply the £1,000 deduction automatically.

If your gross trading income is £1,000 or less and you have no other reason to file a return, you may not need to register for Self Assessment at all. However, if you have other income sources or your total income exceeds the personal allowance, check carefully before assuming you are exempt from filing.

A Practical Decision Checklist

Before deciding which route to take, ask yourself the following:

• Are my total allowable expenses below £1,000? If yes, the trading allowance is almost certainly better.
• Do I have receipts and records for all my expenses? If your record-keeping is incomplete, the allowance removes the risk of a disallowed claim.
• Is my trading income very low or just a side income? The allowance was specifically designed for this situation.
• Am I VAT registered? The trading allowance applies to gross income before VAT, but VAT-registered traders should take care with how they report figures.

The Bottom Line

The trading allowance is a genuinely useful simplification for sole traders with low expenses, but it is not a one-size-fits-all answer. Take five minutes each tax year to add up your actual business expenses. If they come to more than £1,000, itemise them. If they fall short, claim the allowance and keep life simple. Getting this decision right costs you nothing but could save you a meaningful amount each year.
