Self Assessment

The Self Assessment tax return is a system used by HM Revenue & Customs (HMRC) that requires individuals to report their income, expenses, and financial activities to determine how much tax they must pay. It is essential for anyone who is self-employed, earns additional income, or runs a small business. Whether you’re a sole trader, landlord, freelancer, contractor, or company director, understanding Self Assessment is crucial for staying compliant and avoiding penalties.

Completing your tax return correctly ensures you pay the right amount of tax while making the most of the allowances and reliefs available to you.

Who Needs to Complete a Self Assessment Tax Return?

You must usually file a Self Assessment if you:

  • Are self-employed or a sole trader

  • Earn income from rental properties

  • Receive dividends or investment income

  • Have income from abroad

  • Are a company director

  • Have untaxed income that HMRC needs to assess

  • Run a side business, freelance work, or generate income outside PAYE

Understanding whether you need to register for Self Assessment is the first step to meeting your tax obligations.

How to Prepare for Your Self Assessment Tax Return

1. Gather All Sources of Income

To complete your tax return accurately, you need records of:

  • Employment income (P60, P45, P11D)

  • Self-employment earnings

  • Property rental income

  • Dividends and investment income

  • Foreign income

  • Any other taxable earnings

Accurate documentation ensures your tax calculation is correct and helps prevent HMRC issues later.

2. Record Allowable Business Expenses

Allowable expenses reduce your taxable profit, lowering your tax bill. Common deductible costs include:

  • Office expenses

  • Tools and equipment

  • Marketing and advertising

  • Travel and mileage

  • Professional services and subscriptions

  • Home office costs

Maximising your allowable expenses is one of the most effective ways to reduce your tax liability legally.

3. Keep Accurate Financial Records

HMRC requires clear and organised records. Good bookkeeping makes completing your tax return simpler and ensures you can justify claims if HMRC requests evidence.
