Earn extra income? HMRC urges you to file your tax return early
If you have made more than £1,000 from a side hustle last year, you might need to tell HM Revenue & Customs (HMRC), and the earlier you do it, the better.
HMRC is now urging people with extra income to check if they need to register for Self-Assessment and file a tax return. That includes people making money from things like:
- Selling crafts or second-hand clothes online
- Renting out a room or a property
- Creating content on YouTube, TikTok or Instagram
- Dog walking, tutoring or freelancing
- Buying and selling crypto
A lot of people do not realise they have crossed the £1,000 mark, but if you have, it is your responsibility to register and get your tax sorted.
The benefits of getting ahead of the January Self-Assessment deadline
Most people leave it until the last minute, then panic when they realise they owe more tax than they thought.
If you file now, you:
- Find out what you owe nice and early
- Have until 31 January 2026 to pay it, giving you time to save or budget
- Avoid the rush when everyone else is scrambling to file
It is all about making life easier for yourself.
Is this just for side hustles?
No, it also includes landlords, people earning from crypto, and anyone else making extra income outside of PAYE.
If your income is over £50,000 as a sole trader or landlord, you will also need to get ready for Making Tax Digital (MTD) from 2026.
That means using accounting software and sending updates to HMRC four times a year, not just once.
