Step-by-Step Guide to Filing Your Personal Tax Return in the UK

 Whether you’re self-employed, a landlord, or earning additional income outside PAYE, this step-by-step guide will walk you through the process.

Step 1: Determine if You Need to File a Tax Return

 

Not everyone in the UK needs to file a Personal Tax Return. You must file one if you are:

• Self-employed or a business partner
• A company director
• Earning income from savings, investments, or property
• Earning over £100,000 a year
• Receiving foreign income
  If any of these apply, you’ll need to register for Self Assessment with HMRC.

Step 2: Gather All Necessary Documents

 

Before starting, collect the following:

• Your Unique Taxpayer Reference (UTR) number
• National Insurance number
• P60 or P45 (if employed)
• P11D (for expenses or benefits)
• Details of self-employed income and expenses
• Bank statements, investment summaries, and rental income records
  Proper documentation helps you declare accurate figures and avoid HMRC issues later.

Step 3: Register for Self Assessment

 

If you’ve never submitted a Personal Tax Return before, register online through the HMRC portal. Once registered, HMRC will send your UTR number, which you’ll use for all future filings.

Step 4: Complete the Tax Return

 

You can complete your Personal Tax Return online using the HMRC website or approved accounting software. Provide accurate details about:

• Employment income
• Self-employment profits
• Savings and investment income
• Property rental income
• Pensions and other benefits

 

Always double-check your entries before submission — small mistakes can delay processing or result in penalties.

Step 5: Claim Deductions and Reliefs

 

One key advantage of filing a tax return is claiming eligible deductions such as:

• Business expenses
• Charitable donations
• Pension contributions
• Mileage and home office costs (for the self-employed)

 

Maximizing your reliefs ensures you don’t overpay HMRC.

Step 6: Submit and Pay on Time

 

The deadline to submit your Personal Tax Return online is 31 January following the end of the tax year (6 April – 5 April).
Payments for tax owed must also be made by this date to avoid interest and penalties.

Step 7: Seek Professional Help

 

If your finances are complex, or you’re unsure about what to include, consulting a qualified accountant can save time and prevent errors. At Payless Accountant, we help individuals simplify their tax return process and ensure compliance with all HMRC requirements.
