Side Hustle or Selling Online? Here Is When HMRC Wants to Know

eBay, Vinted, Etsy, Depop and Airbnb now send your sales data to HMRC automatically. Clearing out your wardrobe is fine, but if you are trading, once you pass £1,000 in a year you need to declare it. We tell you which side of the line you are on, register you if needed, and file it, all for a fixed fee.

Side Hustle & Online Seller Tax, UK

Selling Is Fine. Trading Is Different. HMRC Can Now See Both.

Since January 2024, online platforms including eBay, Vinted, Etsy, Depop and Airbnb have been required to collect your sales data and report it to HMRC automatically, and HMRC has already received the figures for 2024 and 2025. None of this created a new tax. Selling your own used possessions, clothes, furniture or odds and ends from the loft, is not taxable and never was. What has changed is simply that HMRC can now see your activity, and the people caught out are those quietly running a side business who assumed nobody was looking.

The line that matters is whether you are selling or trading. Clearing out your own things is not trading. Buying to resell, making things to sell, or providing a service is. Once that trading income passes £1,000 gross in a tax year, you need to tell HMRC and usually file a Self Assessment return. Your Tax Help Accountants tells you honestly which side of the line you are on, registers you if you need it, claims the trading allowance or your actual expenses, whichever leaves you paying less, and files it correctly, all for one fixed fee.

The £1,000 trading allowance is measured on gross income, before any costs. Earn under it from a side hustle and there is usually nothing to do. Go over it and you should register, even if your actual profit is small.

Recent Client Outcome

How we sorted a Vinted reseller's two undeclared years

A reseller bought clothes at car boot sales and charity shops and sold them on Vinted and Depop, making a few thousand pounds a year. She assumed that because it was "just selling clothes" it did not count. When the platform reporting rules began, she realised HMRC would now see the activity and panicked.

We confirmed she was trading, not clearing out her own wardrobe, registered her for Self Assessment, and reconstructed two years of income and costs from her platform statements. We claimed her actual expenses where they beat the trading allowance and filed both years properly.

Because she came forward voluntarily, any penalties were kept to a minimum, and she now files one clean return a year. The relief of being straight with HMRC, she said, was worth more than the tax.

Tax Refund Questions Answered

Frequently Asked Questions

Do I have to pay tax on selling my old clothes online?
Generally no. Selling your own used possessions is not trading and is not taxable, however much you sell, so clearing out your wardrobe or loft is fine. Tax only comes in if you are trading, meaning buying to resell, making things to sell, or providing a service.
What is the £1,000 trading allowance?
It is a tax-free allowance for trading income. If your gross income from a side hustle is £1,000 or less in a tax year, you usually do not need to tell HMRC. Over £1,000 and you should register and file a return. It is measured on gross income before costs, and you cannot use it and claim expenses at the same time.
Does HMRC really see my eBay and Vinted sales?
Yes. Since January 2024, platforms including eBay, Vinted, Etsy, Depop and Airbnb must report seller data to HMRC, generally once you pass around 30 sales or roughly £1,700 on a platform in a year. HMRC has already received the 2024 and 2025 figures.
I have not declared my side hustle for a couple of years. What should I do?
Come forward before HMRC contacts you. Voluntary disclosure keeps any penalties far lower. We register you, reconstruct the past years from your records, file what is owed and deal with HMRC for you.
What does it cost?
A fixed fee, quoted up front. There is no charge to find out whether you even need to declare, and we tell you before you commit to anything.
