How to Find and Download the HMRC SA100 Tax Return Form for 2024/25

Every year, countless individuals and businesses across the UK search for the HMRC tax return form to file their taxes accurately and on time.

One of the most common queries from non-clients is, “Where can I download the HMRC SA100 Personal Tax Return form?”

This question spikes in popularity as the tax season approaches, particularly for those managing their self-assessment tax return independently.

In this comprehensive guide, I’ll walk you through everything you need to know about finding, downloading, and submitting the 2024/25 HMRC tax return form, including key deadlines, filing options, and expert tips to streamline the process.

Why the HMRC SA100 Form Matters

The SA100 Personal Tax Return form is the cornerstone of the UK’s self-assessment system, used by individuals to report their income, calculate their tax liability, and ensure compliance with HM Revenue and Customs (HMRC)regulations.

Whether you’re self-employed, a freelancer, a landlord, or someone with multiple income streams, completing this form accurately is critical to avoiding penalties and maximizing allowable deductions.

However, finding the correct form can sometimes be a challenge. Last year, there was a period when the SA100 form was not readily available on the HMRC website. This caused frustration for many taxpayers, who rely on the form to prepare their submissions early. After numerous inquiries and complaints to HMRC, the form was reinstated, much to the relief of those eager to stay ahead of their tax obligations.

For your convenience, you can download the 2025 HMRC Tax Return Form directly via this link. This ensures you have the most up-to-date version of the form, ready for completion.

The traditional method that often causes issues is to try and follow what should be these simple steps:

2. Navigate to the “Self Assessment” section.
3. Locate the SA100 form for the 2024/25 tax year.

Why Download the Form Early?

Downloading the form early allows you to:

• Familiarize yourself with the sections relevant to your income sources (e.g., employment, self-employment, property income, or capital gains).
• Gather necessary financial documents, such as P60s, P45s, bank statements, and expense receipts.
• Avoid the last-minute rush as deadlines approach, reducing stress and the risk of errors.

Key Deadlines for the 2024/25 Tax Return

Submitting your 2024/25 self-assessment tax return on time is crucial to avoid penalties and interest charges. HMRC provides two distinct deadlines depending on whether you’re filing a paper return or submitting online:

• Paper Tax Return Deadline: 31st October 2025
  If you choose to submit a physical copy of the SA100 form, it must reach HMRC by 31st October 2025. Ensure you account for postal delays and retain proof of postage.

• Online Tax Return Deadline: 31st January 2026
  Filing online is often more convenient and allows for a later deadline. You’ll need to register for HMRC’s online services in advance, which can take up to 10 working days to set up. The online system also provides instant confirmation of submission and allows you to track your refund or payment status.

Additional Deadlines to Note

• Tax Payment Deadline: Any tax owed for the 2024/25 tax year must be paid by 31st January 2026, regardless of whether you file on paper or online.
• Registering for Self-Assessment: If you’re new to self-assessment (e.g., you started self-employment in the year to 5th April 2025), you must register with HMRC by 5th October 2025 to avoid penalties.

Paper vs. Online Filing: Which Should You Choose?

Choosing between paper and online filing depends on your preferences and circumstances. Here’s a quick comparison:

Paper Filing

• Best for: Those who prefer physical records or have simple tax affairs.
• Pros: No need for internet access; straightforward for basic returns.
• Cons: Earlier deadline (31st October 2025); slower processing by HMRC.

Online Filing

• Best for: Tech-savvy individuals, complex tax situations, or those seeking a later deadline.
• Pros: Later deadline (31st January 2026); faster processing and refunds; ability to save progress and return later.
• Cons: Requires internet access and HMRC online account setup.

Regardless of your choice, ensure you double-check all entries for accuracy, as mistakes can lead to enquiries or penalties.

Tips for Completing the 2024/25 HMRC Tax Return

Filling out the SA100 form can feel daunting, especially if you have multiple income streams or complex deductions. Here are some expert tips to make the process smoother:

1. Organize Your Financial Records: Collect all relevant documents, including income statements, expense receipts, and bank records, before starting.
2. Understand Allowable Expenses: If you’re self-employed, claim legitimate business expenses (e.g., office supplies, travel, or professional fees) to reduce your taxable income.
3. Check for Tax Reliefs: Explore reliefs such as pension contributions, gift aid donations, or marriage allowance to lower your tax bill.
4. Use HMRC’s Guidance Notes: The SA100 form comes with detailed notes to help you complete each section correctly.
