Selling online? Whether it’s a hobby or a business, you may need to pay tax if your earnings exceed £1,000. From services to content creation, it’s vital to understand self-assessment rules and new reporting obligations for online platforms starting in 2024.

If you are selling anything through an online marketplace, it is important to know that you might be liable to pay tax, whether it is your main source of income or just something a part-time hobby. This applies to a range of activities, so it is worth understanding when you need to register for self-assessment and pay tax.

You may need to report your earnings and pay tax if you are doing any of the following:

• Buying goods to resell, or making things to sell (even if it’s just a hobby that you sell items from);
• Offering services online, such as dog walking, gardening, repairs, tutoring, food delivery, babysitting, or hiring out equipment;
• Creating online content, whether that’s videos, podcasts, or even social media influencing; or
• Earning income by renting out property or land, like letting a holiday home, running a bed and breakfast, or renting out a parking space on your driveway.

There is a Trading Allowance you can claim that allows you to earn up to £1,000 a year from self-employment without having to pay tax or register as self-employed. But if you go over that £1,000 threshold, you will need to register with HMRC as self-employed and submit a self-assessment tax return.

If you are just selling personal items, such as second-hand clothes or unwanted electrical goods, you typically do not need to worry about registering for tax. This is not considered a business activity, so it does not count as trading in the eyes of HMRC.

For those using online platforms to sell goods or services, there are new reporting obligations. Any relevant information about your sales may be reported to HMRC by the platform you use. There is a new requirement for online platforms to report pertinent information collected about online sellers between 1 January 2024 to 31 December 2024 to HMRC by 31 January 2025. This will only happen if you have sold 30 or more items or earned £1,700 (or EURO2,000) in the calendar year. The platform will also provide you with a copy of the information they send to HMRC, which can be helpful when you need to submit your own tax return.
