HMRC is reminding people earning extra income from side hustles to check whether they need to register for Self Assessment and declare the money they make.
The department issued the reminder as wedding season gets under way, highlighting people who earn from activities such as selling wedding stationery, filming first dances or making cakes.
Anyone earning more than £1,000 from a side hustle in a tax year may need to complete a Self Assessment tax return. HMRC said the threshold covers all side hustle income combined.
That means a person earning £600 from wedding photography and £500 from social media posts would need to register, because the total is above £1,000.
HMRC said people can use the additional income tool on GOV.UK to check whether they need to report earnings. If a tax return is required, the tool explains how to register.
New entrants to Self Assessment should register for the 2025 to 2026 tax year by 5 October 2026. They must file their online tax return and pay any tax due by 31 January 2027.
The department said not all extra income is taxable. Selling unwanted personal belongings, such as clearing out a wardrobe, does not usually need to be reported, but regularly selling goods for profit or providing a paid service is likely to count as trading.
