UK Tax Return Guide

Let's talk about tax returns—a subject that, admittedly, many of us would rather avoid. But once you understand the process, it's not as intimidating as it might seem. In this guide, we'll break down everything you need to know about filing your UK tax return.

What Is a Tax Return?

A tax return is a form submitted to HMRC that declares:

  • Your income from all sources
  • Any expenses you're claiming
  • Tax you owe or are owed back

While most employed people have taxes automatically deducted through PAYE, those with additional income or special circumstances need to file a return to ensure they're paying the correct amount.

Who Needs to Submit a Tax Return?

You'll need to file a tax return if any of these apply:

  1. Self-Employed Individuals
    • Earned over £1,000 in a tax year through self-employment
  2. Property Income
    • Rental income exceeding £1,000 annually
  3. High Earners
    • Income over £100,000 (even if on PAYE)
  4. Investment Income
    • Dividends exceeding £2,000
    • Savings interest above your Personal Savings Allowance
  5. Child Benefit Recipients
    • If you or your partner earn over £50,000 and claim Child Benefit
