Side Hustle Income: When Does It Become Taxable?

Earn money from freelancing, selling products online or providing services in your spare time? Even if it is not your main job, additional income in the UK may create tax obligations. This can include graphic design, social media management, tutoring, handmade products or selling goods through online marketplaces. The rules depend on the type of activity, the amount of income you receive and whether you are carrying out a commercial activity for profit.

For many types of additional trading activity, the UK has a £1,000 Trading Allowance per tax year. This threshold applies to gross trading income, not profit. If your total gross trading income exceeds £1,000 in a tax year, you may need to register for Self Assessment and declare your income. However, exceptions apply, and the rules vary depending on the type of income. For example, selling personal belongings you no longer need does not automatically count as trading. It is important to distinguish between occasional sales of your own possessions and buying goods specifically to resell them for a profit.

Do not wait until the end of the tax year to understand your tax position. Keep invoices, payment confirmations and expense records, and check whether you need to register for Self Assessment. If you fall within the Making Tax Digital (MTD) for Income Tax rules, additional digital record-keeping and reporting requirements may also apply. An accountant can help you understand which rules apply to your circumstances and avoid unnecessary mistakes.
