Updated: May 17


Introduction and Understanding the Importance of Previous Tax Returns

Understanding your tax history is crucial for various reasons, whether you're self-employed, a landlord, or an individual taxpayer in the UK. One of the most common queries is how to access previous self-assessment tax returns. This article will guide you through the process of viewing and downloading your old tax returns, tax calculations (SA302), and tax year overviews from the HMRC website.


How to See Previous Self-Assessment Tax Returns in the UK


Why You Might Need Previous Tax Returns

There are several reasons why you might need to access your old tax returns:


  • Financial Planning: Reviewing past returns can help you understand your income trends and plan for the future.

  • Loan or Mortgage Applications: Financial institutions often require past tax returns to assess your creditworthiness.

  • Tax Audits: In case of an audit by HMRC, having easy access to past returns can speed up the process.

  • Legal Requirements: The UK government recommends keeping tax records for at least 22 months following your return. If you're self-employed, you're required to keep your records for at least five years following the 31 January deadline of each tax return.


What Are SA302 and Tax Year Overviews?

Before diving into the steps, it's essential to understand what these documents are:

Tax Year Overview: This document shows the tax paid in any given year and should correlate with your Tax Calculation (SA302) for the corresponding year.


Accessing Online vs. Paper Documents

HMRC provides these documents online, making them readily available for download. However, paper originals are also acceptable, especially if you don't have internet access. These can be ordered by calling HMRC at 0300 200 3310.


Pre-requisites for Accessing Tax Documents

How to Amend a Mistake on a Previous Tax Return in the UK - A Step by Step Process

Making a mistake on your tax return can be a stressful experience. However, correcting these errors is crucial to ensure your financial records are accurate and to avoid potential penalties from HMRC. In the UK, amending a tax return is a straightforward process if you follow the correct steps. This guide will walk you through the process of correcting a mistake on a previous tax return, ensuring you comply with HMRC regulations.


Step 1: Identify the Mistake

Before making any amendments, it's essential to identify and understand the mistake made on your original tax return. Common errors include:


  • Incorrect income reporting

  • Omitting sources of income

  • Errors in calculating expenses

  • Misreporting pension contributions or other deductions


Review your tax return thoroughly to pinpoint the exact error. This will help streamline the correction process and ensure you provide accurate information in your amendment.


Step 2: Gather Necessary Documentation

Once you've identified the mistake, gather all relevant documentation to support your correction. This may include:


  • Payslips or P60 forms

  • Bank statements

  • Receipts for expenses

  • Pension statements


Having these documents ready will make the amendment process smoother and help you provide accurate information to HMRC.


Step 3: Determine the Timeframe for Correction

HMRC allows taxpayers to amend their tax returns within certain timeframes. Typically, you can amend your tax return up to 12 months after the original filing deadline. For example, if you submitted your 2022-2023 tax return by the deadline of 31 January 2024, you have until 31 January 2025 to make amendments.


If you discover a mistake outside of this period, you may need to write to HMRC or make a claim for overpayment relief. The overpayment relief claim must be made within four years of the end of the tax year in question.


Step 4: Access Your Tax Return Online

Most taxpayers submit their tax returns online through the HMRC website. To amend your return online:


  1. Log in to your HMRC account: Visit the HMRC website and log in using your Government Gateway user ID and password.

  2. Access your Self Assessment: Navigate to the Self Assessment section of your account.

  3. View your submitted tax returns: Select the tax return you need to amend.

  4. Make the necessary changes: Follow the prompts to update the relevant sections with the correct information.


Ensure you review all changes carefully before resubmitting your amended return.


Step 5: Submit Your Amended Tax Return

After making the necessary changes, submit your amended tax return. HMRC will process the amendment and notify you of any changes to your tax liability. If you owe additional tax, ensure you pay it promptly to avoid interest and penalties.


Step 6: Monitor Your HMRC Account

After submitting your amendment, monitor your HMRC account for updates. HMRC will review your amended return and may contact you for further information. It's essential to respond promptly to any requests to avoid delays in processing your amendment.


Step 7: Keep Accurate Records

Maintaining accurate records is crucial for future reference and in case HMRC has any queries about your amendment. Keep copies of:


  • The original tax return

  • The amended tax return

  • Correspondence with HMRC

  • Supporting documentation


Dealing with Errors Beyond the Amendment Period

If you discover an error after the amendment period has expired, you may still have options:


  1. Overpayment Relief: As mentioned earlier, you can claim overpayment relief within four years of the end of the tax year. Write to HMRC explaining the mistake and provide supporting documentation.

  2. Contact HMRC: If you're unsure about your options, contact HMRC for guidance. They may be able to assist you in resolving the issue.


Professional Assistance

Correcting a mistake on your tax return can be complex, especially if the error is significant or involves multiple areas of your return. Consider seeking professional help from an accountant or tax advisor. They can:


  • Review your tax return for errors

  • Assist with the amendment process

  • Provide advice on how to avoid future mistakes


Hiring a professional can save you time and ensure your amendment is handled correctly.


Avoiding Future Mistakes

To avoid future mistakes on your tax returns:

  • Keep detailed records: Maintain accurate and up-to-date records of all income and expenses.

  • Use tax software: Consider using reliable tax software to help you prepare your return accurately.

  • Stay informed: Keep up to date with tax laws and regulations to ensure compliance.

  • Double-check your return: Review your tax return carefully before submitting it to catch any errors.
