What is a Side Hustle?

A side hustle is an additional job or activity done alongside your primary employment to earn extra income. This can include freelance work, part-time gigs or selling products online, providing an opportunity to explore passions and increase financial stability.

What is Side Hustle Tax?

Side Hustle Tax is the Income Tax applied to earnings from your side hustle. In the UK, any additional income from a side hustle is subject to the same tax rules as primary income, potentially affecting your overall tax bracket and liability.

Who Needs to Pay Side Hustle Tax?

Anyone earning extra income from a side hustle must pay tax if:

  • Your Total Income Exceeds Your Personal Allowance - Combined income from your main job and side hustle above the personal allowance is taxable.
  • You Earn More Than £1,000 from Your Side Hustle - The first £1,000 is tax-free, but earnings above this threshold must be reported to HMRC.
  • You Are Self-Employed - Self-employed individuals must register with HMRC and complete a Self Assessment Tax Return.
