HMRC Confirms New Tax Reporting Rule for Side Hustles and Online Selling
HM Revenue & Customs (HMRC) has issued a formal reminder that a significant change to tax reporting rules for individuals earning extra income will become legally enforceable from April 2026. This rule, part of the government’s strategy to improve tax compliance in the digital economy, requires online marketplaces to directly report seller information to HMRC.
What is the New HMRC Rule?
The regulation mandates that digital platforms—including eBay, Vinted, Depop, Airbnb, Uber, and Etsy—must collect and automatically share detailed information about their users’ income with HMRC. This initiative, known as the ‘Model Reporting Rules for Digital Platforms’, is an international effort led by the Organisation for Economic Co-operation and Development (OECD), which the UK is implementing.
Previously, the responsibility for declaring this income rested solely with the individual taxpayer. From April 2026, HMRC will receive this data directly from the platforms, creating a parallel record against which it can check Self Assessment tax returns.
Who is Affected by This Change?
This rule affects a wide range of UK individuals who earn money through digital platforms. You are likely within scope if you:
- Sell goods for a profit on sites like eBay, Vinted, or Facebook Marketplace.
- Rent out a property or a room on platforms like Airbnb.
- Provide a service such as taxi driving (Uber, Bolt), food delivery (Deliveroo, Just Eat), or freelance tasks (Fiverr, TaskRabbit).
- Earn money from creative content or affiliate sales.
The key factor is not the platform type but whether the activity generates taxable income. The rule applies regardless of whether you consider it a business, a ‘side hustle’, or occasional selling.
Understanding Your Tax Obligations
It is crucial to distinguish what income is taxable. HMRC’s existing rules still apply:
- Trading Allowance: You can earn up to £1,000 per tax year (6 April to 5 April) from miscellaneous trading income tax-free. This is known as the Trading Allowance. If your gross income from these platforms exceeds £1,000, you must register for Self Assessment and declare it.
- Capital Gains Tax on Personal Items: Selling personal items you own for less than you paid for them is not taxable. However, if you sell an item for more than £6,000 (and it’s not your main car or home), you may have a Capital Gains Tax liability to report.
- Property Income: The Rent-a-Room Scheme allows you to earn up to £7,500 per year tax-free from letting a room in your main home. Income above this threshold must be declared.
The new reporting rule does not change these underlying tax thresholds; it changes how HMRC receives the data to check compliance with them.
What This Means in Practical Terms
For compliant taxpayers, this change should be seamless. If you are already correctly declaring all your taxable income via a Self Assessment tax return, the platform’s report to HMRC will simply match your own submission.
The primary impact is for those who may have under-reported or not declared this income, whether intentionally or through misunderstanding the rules. From 2026/27 onwards, HMRC’s systems will be able to automatically cross-reference the data supplied by platforms with individual tax records. Discrepancies are likely to trigger inquiries or notices prompting taxpayers to review their returns.
HMRC’s warning emphasises that taxpayers are ‘legally required’ to ensure their tax affairs are in order. The onus remains on the individual to declare taxable income correctly and on time. The new data stream provides HMRC with a powerful tool to identify non-compliance.
If you engage in these activities, now is the time to review your records for the current and previous tax years. Check if your total gross income from all side hustles and online sales exceeds the £1,000 Trading Allowance or other relevant thresholds. If you need to register for Self Assessment or amend a past return, it is advisable to do so proactively.
The implementation of this rule marks a significant shift in HMRC’s ability to track income from the digital and ‘gig’ economy. Understanding your obligations before the reporting begins is key to ensuring compliance and avoiding potential penalties.
