UK Trading Allowance: Side Hustles, Online Selling & HMRC Tax Rules

Whether you sell unwanted items online, rent out a room through Airbnb, freelance through digital platforms, deliver food, create online content or offer services such as gardening and babysitting, earning extra income can have tax implications.

With more people turning to side hustles and online platforms to generate additional income, it is important to understand when you need to tell HMRC about your earnings and when tax may be payable.

The government has announced plans to increase the Self Assessment reporting threshold for trading income from £1,000 to £3,000 by 2029. The proposed change is designed to reduce administrative requirements for people with smaller side businesses and occasional trading activities.

However, the important point is that this proposal does not increase the £1,000 trading allowance. This means tax could still be payable on profits even if you do not have to complete a Self Assessment tax return.

HMRC also plans to introduce a simplified online service for people who have tax to pay but are not required to submit a full tax return.

What Is the Trading Allowance?

The trading allowance allows individuals to earn up to £1,000 of trading income during a tax year without paying tax on that income or normally having to report it to HMRC, provided no other reporting obligations apply.

It can be particularly useful for people earning occasional income from a small side business, casual services or online selling.

However, it is important to distinguish between trading income and profits. The £1,000 allowance relates to your trading income, rather than simply the profit you make.

How Does the Trading Allowance Work?

If your trading income is more than £1,000, you generally need to consider how your taxable profit should be calculated.

There are two main approaches.

1. Calculate Your Actual Profit

You can calculate your taxable profit by deducting allowable business expenses and, where relevant, capital allowances from your business income.

This is sometimes referred to as the profit method.

2. Claim the £1,000 Trading Allowance

Instead of claiming your actual expenses, you may be able to deduct the £1,000 trading allowance from your trading income.

This is often referred to as partial relief.

For example, if your annual trading income is £4,000 and you use the trading allowance, your taxable trading profit would generally be £3,000.

The most suitable option will depend on your individual circumstances and the level of your allowable business expenses.

Where the relevant thresholds are met, taxable profits may be subject to Income Tax and National Insurance contributions.

When Might You Still Need to Register?

The trading allowance does not necessarily mean that registering as self-employed is unnecessary in every situation.

There may be other reasons why registering and reporting your income could be beneficial or required.

For example, registration may help you:

• Build or protect your National Insurance record through voluntary Class 2 contributions, where eligible.
• Demonstrate self-employed earnings for certain benefit claims, such as Maternity Allowance.
• Meet other Self Assessment reporting requirements.
• Provide evidence of self-employed income for certain applications or financial arrangements.

Your circumstances should be considered before deciding whether registration is necessary.

The Trading Allowance Has Important Limits

Although the trading allowance can simplify tax calculations, it is not suitable in every situation.

The allowance can reduce taxable trading income to nil, but it cannot create a trading loss.

If your allowable business expenses are less than £1,000, using the trading allowance may be simpler and potentially beneficial.

However, if your genuine allowable expenses are greater than £1,000, calculating your actual expenses may result in a lower taxable profit and therefore potentially a lower tax bill.

What If Your Income Is Below £1,000?

Even where trading income is below £1,000, there can be circumstances where completing a tax return is worthwhile.

For example, if you have made a trading loss, reporting the loss may allow you to carry it forward or, where the rules permit, offset it against other income.

Professional advice can help determine whether reporting the income voluntarily would be beneficial.

The £1,000 Allowance Applies to Your Total Trading Income

The trading allowance is not a separate £1,000 allowance for every side hustle.

If you operate several small businesses or earn income from multiple trading activities, the £1,000 limit generally applies to your combined trading income.

For example, someone earning £700 from freelance work and £600 from selling goods as a side business would have total trading income of £1,300, rather than two separate £1,000 allowances.

When Can You Not Claim the Trading Allowance?

There are also restrictions on using the trading allowance.

It cannot generally be claimed where trading income is received from:

• A company controlled or owned by you or someone connected to you.
• A partnership in which you or someone connected to you has an interest.
• Your employer.
• Your spouse’s or civil partner’s employer.

These restrictions are designed to prevent the allowance from being used in situations where income could otherwise be structured to obtain an unintended tax advantage.

Do Online Platforms Report Your Income to HMRC?

One common misconception is that HMRC cannot see income earned through online platforms.

That is no longer a safe assumption.

Under international reporting rules, digital platforms may be required to collect information about sellers and service providers and report certain details to tax authorities, including HMRC.

This can apply to people using platforms such as eBay, Vinted and Airbnb, as well as freelancers, drivers, delivery workers and content creators receiving payments through digital platforms.

What Does This Mean for Online Sellers?

For example, eBay may have reporting obligations where a seller reaches certain transaction or sales thresholds.

However, being reported to HMRC does not automatically mean that you owe tax.

The platform reporting thresholds are primarily used to determine when information must be reported. They do not determine whether your activity is taxable.

This means you could potentially be reported to HMRC even though no tax is due. Equally, you could have a tax liability without triggering a particular platform’s reporting threshold.

Selling Personal Items Is Not Always the Same as Running a Business

It is also important to understand the difference between occasionally selling unwanted personal possessions and carrying on a trade.

Selling some old clothes, furniture or household items that you no longer need does not automatically mean you are running a business.

However, if you regularly buy or make goods with the intention of selling them for a profit, your activities could potentially be treated as trading.

The facts and circumstances of the activity are important.

Keep Good Records of Your Side Hustle Income

If you earn additional income, keeping accurate records is one of the easiest ways to stay on top of your tax obligations.

You should consider keeping records of:

• Sales and other trading income.
• Platform fees and commissions.
• Allowable business expenses.
• Equipment and other business purchases.
• Dates and details of transactions.
• Relevant invoices and receipts.
• Information provided by online platforms.

Good records can help you determine whether you are trading, calculate your taxable profit and support any expenses or reliefs you claim.

What Should Side Hustlers Do Now?

The rules surrounding online income and digital platform reporting are becoming increasingly important.

If you sell online, freelance, rent out property or equipment, create content or provide services outside your main employment, do not assume that small amounts of income automatically fall outside the tax system.

Review your total trading income, keep appropriate records and check whether you need to register with HMRC or report your income.

If you are unsure whether your side hustle is taxable, getting professional advice early can help you avoid unexpected tax bills and compliance problems.

Key Takeaway

The £1,000 trading allowance can make tax simpler for people with small amounts of trading income, but it does not mean every side hustle is automatically tax-free.

The proposed increase in the Self Assessment reporting threshold to £3,000 should reduce administrative requirements for some taxpayers, but it does not increase the trading allowance or remove potential tax liabilities.

As HMRC receives more information from digital platforms, keeping accurate records and understanding your reporting obligations is more important than ever.
