Starting January 2023, digital platforms like eBay, Airbnb, and Uber will begin sharing seller earnings data with HM Revenue & Customs (HMRC) as part of a global effort to curb tax evasion. If you're earning through these platforms, it's crucial to understand if you're liable for tax, especially if your earnings exceed certain thresholds. With the new rules in place, ensure you're informed about your tax obligations and consider contacting HMRC or a tax professional for guidance to avoid any surprises.
