By Chandraketu Tripathi · Updated April 2026 · Fact-checked Tax · April 2026The era of undeclared side income is ending in the UK. From January 2024, digital platforms including eBay, Vinted, Etsy, Airbnb, Fiverr and Uber are required to collect and report seller income to HMRC automatically. HMRC has issued specific warnings to those with side hustle income in 2026. Here is everything you need to know to stay compliant.
The £1,000 Trading AllowanceEvery UK taxpayer has a £1,000 trading allowance per tax year. If your total gross income from all self-employment and side hustle activities (before expenses) is under £1,000, you do not need to declare it to HMRC. This allowance covers selling items online, occasional freelance work, and other small trading activities. If your income is between £1,000 and £12,570, you must register for Self Assessment and declare the income — but you will not pay tax if your total income (including employment and side hustle) remains below the personal allowance of £12,570. If your income exceeds £12,570, you will pay income tax at 20% on the excess (basic rate). Selling on eBay, Vinted and Etsy — What Is Taxable?Selling your own unwanted personal possessions is not taxable — this is not 'trading' for tax purposes. If you occasionally sell old clothes, books or household items you own, HMRC does not consider this a business. However, if you buy goods specifically to resell them at a profit, manufacture items to sell, or sell regularly with a commercial intent, this is trading — and the income is taxable above the £1,000 trading allowance. 💡 eBay, Vinted, Etsy and similar platforms now automatically report the total amount you received in the year to HMRC. HMRC will compare this against your tax return. If you have not declared income above £1,000, expect to hear from HMRC. The penalty for undeclared income can be up to 100% of the tax owed in serious cases. Rent-a-Room Relief — Airbnb and LodgersIf you rent a room in your main home — whether to a lodger or via Airbnb — you benefit from rent-a-room relief of £7,500 per year (£3,750 if shared with a co-owner). Income below this threshold is tax-free and does not even need to be declared. Above the threshold, you choose between declaring the full income and deducting expenses, or paying tax only on income above £7,500. ⭐ OUR VERDICT HMRC's increased focus on side hustle income in 2026 means that anyone earning above £1,000 per year from trading, freelancing or letting who has not registered for Self Assessment faces a growing risk of an unexpected tax investigation. The solution is straightforward: register for Self Assessment at gov.uk if your side income exceeds £1,000, keep records of all income and expenses, and declare honestly. The penalties for non-disclosure significantly exceed any tax that would have been owed. Frequently Asked QuestionsDo I have to pay tax on my eBay or Vinted sales? Not always. Selling your own unwanted personal possessions is not taxable. However, if you buy items specifically to resell them, sell regularly or run what HMRC would consider a trading business, the income above the £1,000 trading allowance is taxable and must be declared via Self Assessment. What is the HMRC trading allowance? The trading allowance is £1,000 per tax year. If your total gross income from all self-employment and side hustle activities is below £1,000, you do not need to declare it. Above £1,000, you must register for Self Assessment and declare the income, though you may not owe any tax if your total income is below the personal allowance. How does HMRC know about my side income? Digital platforms including eBay, Vinted, Etsy, Airbnb, Uber and Fiverr have been required since January 2024 to report user income to HMRC automatically. HMRC receives this data and cross-references it against tax returns. If you have not declared income that the platform has reported, HMRC will typically send an inquiry letter. Do I need to register for Self Assessment for a side hustle? Yes, if your gross side hustle income exceeds £1,000 in a tax year. Register at gov.uk/register-for-self-assessment. The deadline to register for 2025/26 is 5 October 2026. Late registration incurs a penalty. If you are unsure whether your activities constitute trading, Citizens Advice or an accountant can help you assess your position. |
