Overview

• Since 2025, HMRC has been receiving platform reports on users typically exceeding 30 transactions a year or roughly £1,700 in gross sales and is matching this data to tax records.
• Sellers who fail to declare income above the £1,000 trading allowance may receive reminder letters that can escalate to full inquiries if ignored.
• Vinted says completing a seller report and having details shared with HMRC does not automatically mean tax is due, and sales made for less than original cost are not taxable.
• People regularly buying to resell or offering services online may need to file a Self-Assessment return, whereas one-off sales of personal items are unlikely to draw scrutiny.
• Advisers urge sellers to keep detailed records of sales and related costs such as postage and courier fees to support filings and claim allowable expenses.
