📦 Side Hustle Tax Guide

What UK side hustlers need to know about the £1,000 trading allowance, records and Self Assessment.

Start with the trading allowance

The UK's trading allowance lets many people earn up to £1,000 gross from side-income activities without needing to calculate full business profits in the usual way.

Once you go past that, you usually need to think about registration, records and whether a tax return is needed.

Common side hustles

Even if a side hustle starts casually, keep basic records early. It saves a lot of pain later.

When HMRC becomes relevant

  1. You move past hobby territory into regular profit-seeking activity
  2. Income exceeds the trading allowance
  3. You need to file Self Assessment
  4. Your side income affects benefits, tax bands or student loan repayments
