HM Revenue & Customs (“HMRC”) is urging people who earn money on the side to check whether they need to register for Self Assessment and declare that income. The side hustle tax reminder applies to anyone making extra cash outside their main job, whether through selling online, offering services, or renting out property.
HMRC’s Side Hustle Tax Reminder
The message is straightforward. If your extra earnings cross a certain threshold, you may have a legal duty to tell HMRC about them. Many people assume casual income does not count, but that is not always true.
Who This Applies To
According to HMRC, the reminder is aimed at people earning money from side hustles. That covers a wide range of activities. For example, it can include selling handmade goods, tutoring, dog walking, driving, content creation, or letting out a room.
The source does not list every qualifying activity in detail. However, the general principle is clear: if you earn income beyond your regular employment, you should check whether it needs to be reported. If you are unsure, HMRC’s guidance is designed to help you work that out.

The core fact from HMRC is simple. People with side hustle income should check if they need to register for Self Assessment and declare their earnings.
The raw reminder does not state a specific income threshold, deadline, or penalty figure. Rather than guess, it is worth noting that these details are not spelled out in the announcement itself. For exact figures, readers should consult HMRC’s full guidance.
In general terms, Self Assessment is the system HMRC uses to collect tax that is not deducted automatically through PAYE. Because side hustle income usually is not taxed at source, it often falls into this system.
Background
Side hustles have grown steadily as more people take on flexible or online work alongside a main job. As a result, HMRC has repeatedly stressed that extra income can carry tax obligations.
This reminder fits a wider pattern of HMRC communication on the topic. The department wants to make sure people understand their responsibilities before problems arise, because unpaid tax can lead to interest and penalties. In addition, digital platforms now share more data with tax authorities, so undeclared income is easier to identify than before.
The aim, therefore, is prevention. HMRC would rather people check their position early than face difficulties later.
What To Do Next
If you earn money from a side hustle, the practical steps are clear:
- Check whether your extra income means you need to register for Self Assessment.
- Register with HMRC if you are required to do so.
- Keep records of what you earn and any related expenses.
- Declare the income and pay any tax due through Self Assessment.
The announcement does not quote a specific registration deadline. Even so, acting early is sensible, because registering and filing on time helps you avoid penalties. If you are uncertain whether your earnings qualify, HMRC’s online tools can help you decide before you commit to anything.
