Let’s Get Started
Whether you're selling pre-loved clothes, flipping collectibles, or building a full-fledged eBay business, understanding your tax responsibilities is crucial. While it might seem like a casual side hustle, HMRC has clear rules on when online sales become taxable. This guide breaks down what you need to know for the 2024/25 tax year, so you can stay compliant, avoid surprises, and keep more of what you earn.
Introduction to eBay Tax
If you’re looking to make some extra cash by selling items on eBay, it’s important to know that your sales may need to be reported to HMRC, and you may need to pay tax on your profits.
The tax rules for eBay sellers depend on how much you earn, the type of items you sell, and how often you sell them. In the UK, the main taxes that can apply to eBay sales are income tax and Value Added Tax (VAT). Income tax may need to be paid on profits you make from selling goods, while VAT could apply if your sales reach a certain value.
To stay compliant, you’ll need to check if your eBay sales are considered taxable and, if so, register for Self-Assessment with HMRC. Understanding these rules will help you avoid unexpected tax bills and ensure you’re following the correct procedures when selling on eBay.
Types of eBay Sellers
Not all eBay sellers are treated the same when it comes to tax. Your tax obligations depend on how often you sell and the value of the items you list.
Casual sellers, who only sell items occasionally, such as clearing out personal possessions, generally don’t need to pay tax on their eBay sales, unless they sell an individual item for more than £6,000, which could trigger Capital Gains Tax.
However, if you’re a regular seller, making frequent sales or buying items specifically to resell, you may need to pay income tax and National Insurance on your profits. Businesses that use eBay to sell goods as part of their trade may also need to register for VAT if their taxable turnover exceeds £90,000 per year.
For example, if you consistently sell items and make a profit, you’ll need to keep accurate records and may need to register with HMRC to ensure you’re paying the correct taxes.
Understanding which type of seller you are is key to following the right tax rules and staying compliant.
When does HMRC want a slice of your eBay pie?
Not every eBay sale is taxable. In general, HMRC only taxes profits from selling when you are trading or making significant gains. Selling your old clothes at a loss is generally fine. Tax applies when you sell items for more than you paid, especially if you do so regularly or with the intention of making a profit.
But HMRC takes interest when you’re making a profit. Many people are surprised to learn that even occasional selling can trigger tax obligations. In some cases, you may have to pay tax if your sales exceed certain thresholds or involve valuable items.
The taxman looks for patterns suggesting you’re trading rather than just decluttering. Buying items specifically to resell them, frequent sales, or maintaining stock all wave red flags. If you buy goods with the intention to resell, this is a key factor HMRC considers.
If you’re selling handmade items or purchasing wholesale to sell retail, you’re almost certainly trading in HMRC’s eyes. The good news? The first £1,000 of your trading income is tax-free thanks to the Trading Allowance.
The £1,000 trading allowance explained
This handy allowance means if your total trading income is under £1,000 for the tax year, you don’t need to report it to HMRC at all. This £1,000 is a threshold for reporting and tax purposes. This covers all your side hustles combined, not just eBay.
Once you exceed the £1,000 threshold in sales, you’ll need to register for Self-Assessment and report your income. Your full income from all sources is considered when determining your tax obligations, not just your eBay sales.
You can choose between using this £1,000 allowance or deducting your actual business expenses, whichever gives you the lower tax bill. Be careful though, you can’t use both approaches.
Signs HMRC will view you as a trader
Selling frequency is a major indicator. Listing dozens of items weekly looks very different from occasional clear-outs. HMRC can review your transactions on digital platforms like eBay to assess your trading activity.
Modifications matter too. If you’re upcycling furniture or customising items before selling, that suggests commercial intent.
The time between buying and selling is telling. Quick turnarounds hint at trading, while selling items you’ve owned for years looks more like personal disposal.
Professional-looking listings, branded packaging, or business cards all strengthen the case that you’re running a business. Using digital channels for sales can further indicate a business operation. I once helped a client who didn’t realise her beautifully branded packaging had effectively declared her trading status to HMRC.
Self-Assessment essentials for eBay sellers
Once your trading income tops £1,000, you must register for Self-Assessment by 5th October after the tax year ends. For example, by 5th October 2024 for the 2024/25 tax year. Note that the tax year runs from 6 April to 5 April the following year, which is different from the calendar year (1 January to 31 December) often used for other types of income reporting.
Keep meticulous records of everything, purchase costs, selling prices, fees, postage, and any other expenses. Screenshots of sales can be helpful too.
You’ll need to complete the self-employment section of your tax return, even if you have a day job with PAYE income. Remember that profits from eBay selling are added to your other income when calculating your tax band.

Tax-deductible expenses for online sellers
eBay and PayPal fees are fully deductible business expenses that reduce your taxable profit. Deductible expenses can include services such as professional photography or accounting. Packaging materials, postage costs, and printer ink used for shipping labels can all be claimed.
If you store inventory at home, you may claim a proportion of your household bills based on the space used exclusively for business. Travel costs for sourcing stock or taking parcels to the post office count too.
Don’t forget less obvious costs like website hosting, professional photography, or accounting software subscriptions. These services are legitimate business expenses and can significantly reduce your tax liability.
VAT considerations as you grow
Most small eBay sellers won’t need to worry about VAT initially. But once your taxable turnover approaches £90,000 in any 12-month period, you’ll need to register. For the 2025/26 tax year, make sure to check if the VAT registration threshold or rules have changed, as staying updated is crucial for compliance.
VAT registration means charging VAT on your sales to UK customers and completing quarterly VAT returns. The benefit? You can reclaim VAT on your business purchases.
International sales have their own VAT complexities, especially post-Brexit. Different rules apply to EU and non-EU sales, so seek advice if you sell internationally. Some sellers may benefit from a one-off consultation to clarify their VAT obligations.
Record Keeping and Tax Returns
Good record keeping is essential for anyone selling on eBay, whether you’re a casual seller or running a business.
You’ll need to keep detailed records of every item sold, including the date, sale price, and any fees paid to eBay or other online marketplaces. It’s also important to track your expenses, such as the cost of goods, postage, and packaging, as these can reduce your taxable profit.
If you’re required to pay tax on your eBay sales, you’ll need to file a Self-Assessment tax return with HMRC. The HMRC online tool can help you check if you need to pay income tax and National Insurance on your online sales, and guide you through the process of registering for Self-Assessment.
Keeping accurate records not only helps you calculate your profit and tax owed, but also ensures you’re prepared if HMRC requests information about your eBay sales.
Consequences of Non-Compliance
Ignoring your tax obligations as an eBay seller can have serious consequences. If you fail to declare your eBay income or don’t pay the correct amount of tax, HMRC may impose penalties and charge interest on any unpaid tax.
In some cases, HMRC can investigate your tax affairs and, if they find that you’ve deliberately avoided paying tax, you could face penalties of up to 100% of the tax owed. For example, if you regularly sell items on eBay and don’t report your income, you risk being fined and having to pay backdated taxes.
To avoid these issues, it’s essential to follow the tax rules, keep accurate records, and ensure you pay any tax due on your eBay sales. Staying compliant not only protects you from penalties but also gives you peace of mind as you grow your online sales.
Final Thoughts
The line between casual selling and trading isn't always clear-cut. HMRC is getting better at spotting undeclared income from online platforms.
When in doubt, keep records. It's much easier to prove you weren't trading if challenged than to recreate missing documentation later.
The £1,000 trading allowance gives casual sellers breathing space. But once your eBay side hustle grows beyond that, proper tax compliance becomes essential.
Getting your eBay tax affairs in order early can prevent sleepless nights and hefty penalties. A little organisation now saves significant stress later.
