What is HMRC SA104 Form and Its Versions: SA104S and SA104F?

Updated: May 2

SA104 is a supplementary part of your self-assessment tax return. It is used to report the figures related to a company operated as in a partnership. The form is used by HMRC so that you can inform them about your portion of the income you earn and any losses that result from the partnership. SA104 is only for individual partners. SA104 is only intended for the partners as individuals and not for the partnership itself, which is why it submits the form SA800.



Overview of HMRC SA104 Form


The HMRC SA104 Form in the UK is a critical component of the self-assessment tax return system. This form serves as an additional information form, attached to the main Self-Assessment tax return, for taxpayers to provide supplemental details about their income and capital gains. It's specifically designed to report figures related to companies operated in partnerships. The SA104 Form enables the HM Revenue and Customs (HMRC) to assess individual taxpayers' shares of profits or losses from a partnership, instead of focusing solely on the partnership entity as a whole​​​​​​.


What is an SA104 Form?


Purpose and Necessity of the SA104 Form


The primary purpose of the SA104 Form is to enhance the transparency and integrity of the UK's tax system. It ensures that all sources of income and capital gains are accurately reported by the taxpayers. This form is particularly necessary when a taxpayer has income or capital gains that are not covered by the main Self-Assessment tax return. By providing a structured format for disclosing additional income sources and capital gains, the SA104 Form plays a vital role in accurate tax reporting​​​​​​.



Content and Key Sections


HMRC Form SA104 may include various types of income such as employment income, self-employment income, partnership income, UK property income, foreign income, and other specific financial situations. These sections are crucial for HMRC to ensure that all income sources and capital gains are accurately reported by the taxpayers. The comprehensive nature of the form helps HMRC assess the tax liability of individuals accordingly​​​​.



The Role of SA104 Form in Tax Reporting and Compliance

Electronic Submission and Consequences of Non-Compliance


Taxpayers have the convenience of submitting the SA104 Form electronically as part of the Self-Assessment tax return. However, failure to file the SA104 Form when required could lead to inaccurate tax reporting, potential fines, and legal repercussions. This highlights the importance of complying with the filing requirements set by HMRC​​.

The form plays a pivotal role in providing HMRC with a complete overview of a taxpayer’s financial situation​​.



Filing Process and Integration with Self-Assessment Tax Return

Role in Reducing Tax Evasion and Enhancing Fairness

The Importance of Compliance and Accurate Reporting


Filling out the SA104 Form accurately is not just a legal requirement; it's a responsibility that each taxpayer owes to the tax system.

Common Challenges and Solutions


One of the common challenges faced by taxpayers is determining which sections of the SA104 Form are relevant to their income types. To address this, taxpayers should carefully review their income sources and match them with the respective sections in the form. In case of confusion, seeking advice from a tax professional or consulting HMRC's guidance can be helpful. Another challenge is ensuring that all income and capital gains are accurately reported. Taxpayers should keep thorough records of their finances throughout the year to simplify this process.



The Role of Digital Tools and Resources


The availability of digital tools and resources has made the process of filling out and submitting the SA104 Form more accessible and efficient.

In-Depth Issues of HMRC SA104 Form


Continuing from our discussion on the HMRC SA104, SA104F, and SA104S forms, let's delve into additional specific details about the SA104S Form based on the latest notes for the tax year 6 April 2022 to 5 April 2023. These details provide a deeper understanding of the form's functionalities and requirements, essential for accurate and compliant tax reporting.



Joining or Leaving a Partnership


For individuals who became partners after 5 April 2022, it's important to enter the joining date in Box 3 of the SA104S Form. This information is crucial for HMRC to understand when you started accruing income from the partnership. Similarly, if you left the partnership between 5 April 2022 and 6 April 2023, this should be reported in Box 4. Timely updating of these details ensures correct tax and National Insurance Contributions (NICs) calculations​​​.



Unique Taxpayer Reference and Partnership Reference Number


When filling out the SA104S Form, you must include your Unique Taxpayer Reference (UTR) and the partnership's tax reference number. The UTR is a critical identifier for your tax records, while the partnership reference number ensures that your submission is correctly linked to your business entity. If you’re a partner in a foreign partnership, your own UTR needs to be used in Box 1​​.



Basis Period for Tax Calculations


The basis period, which determines the time frame for which you pay tax on profits, is crucial. For established businesses, the basis period typically aligns with the accounting period. Correctly identifying and reporting this period in Boxes 6 and 7 is essential for accurate tax calculations​​.



Reporting Partnership Profits or Losses


The share of the partnership’s profit or loss, along with any basis period adjustments, must be reported in Boxes 8 and 9. If your basis period differs from the partnership’s accounting period, you’ll need to make necessary adjustments to ensure accurate reporting. In cases of disputes regarding profit or loss shares, referrals can be made to the Tribunal Service, but both HMRC and the nominated partner must be notified of this action​​.



Provsional Figures and Adjustments


Provisional figures, if used, should be indicated in Box 20, with an explanation and a timeline for final figures submission. Box 10 deals with adjustments due to changes in accounting practice, like moving away from the cash basis, which are typically spread over six tax years​​.



Averaging Adjustment and Foreign Tax Deduction


For those eligible for averaging adjustments, changes in profit should be reflected in Box 11. When claiming foreign tax as a deduction (Box 12), it's important to note that this cannot be done concurrently with claiming Foreign Tax Credit Relief​​.



Overlap Relief and Profit Carry Forward


Overlap relief (Box 13) is applicable under certain conditions, like ceasing partnership or changing accounting dates. Any overlap profit from previous years, along with new overlap profits for the tax year, should be reported in Box 14. Overlap profits can be carried forward and set off against future profits​​.



Adjusted Profit and Losses


Box 16 is used for declaring adjusted profit or loss for the tax year. If losses were incurred in previous tax years, they can be set off against this year's profit (Box 17). The taxable profit after considering these losses is reported in Box 18​​.



Other Business Income and Total Taxable Profits


Any other business income not included in partnership accounts, like personal professional income or coronavirus support scheme payments, is reported in Box 19. Your share of total taxable profits for the business year is then calculated and reported in Box 20​​.



Claiming Tax Relief for Losses


Partnership losses might be eligible for tax relief. If a loss claim has been made in the tax year, it should be included in Boxes 22 to 24, with detailed information provided on the tax return form. Adjusted losses for the tax year are reported in Box 21​​.



Loss Carryback and Exemption from Class 4 NICs


Losses can be carried back to previous years to set off against income or capital gains (Box 23). Additionally, exemptions from paying Class 4 NICs, under certain conditions like reaching state pension age or non-residency, are reported in Box 26​​.



Carry Forward Losses and NIC Contributions


Total loss to carry forward after all set-offs is reported in Box 24, helping in future tax planning. Box 25 details voluntary contributions towards Class.

Key Changes to the SA104 Form in 2024


1. Digitalisation of the Tax System

In line with the government’s initiative to digitise the tax system, significant enhancements have been made to the electronic submission process of the SA104 forms. This change aims to streamline the submission process and reduce errors associated with manual entries. Partners are encouraged to use the updated digital platforms, which now offer pre-filled information from previous returns and real-time tax calculation.


2. Changes in Reporting Requirements

The 2024 updates have introduced new reporting requirements on the SA104 forms. These changes are particularly noticeable in the SA104F form, which now requires more detailed information about the sources of income from the partnership. This includes specifying income from digital assets, which reflects the evolving nature of modern business practices.


3. Alignment with Making Tax Digital (MTD)

The SA104 forms are now fully integrated into the Making Tax Digital framework. This integration means that all partners must maintain digital records of their financial transactions related to the partnership and use MTD-compatible software to submit their tax returns. This move is designed to improve the accuracy of tax records and ease compliance.


Impact on Partnerships


1. Increased Compliance

The new updates mandate stricter compliance and detailed record-keeping. Partnerships need to adapt their accounting practices to ensure all relevant financial transactions are recorded digitally from the start of the financial year. This shift may require partnerships to invest in new accounting software or training to meet the compliance standards.


2. Enhanced Accuracy and Transparency

The digital-first approach is expected to reduce common errors seen in tax returns, such as mathematical mistakes or omitted entries. This increased accuracy will aid in faster processing of returns and more timely updates on tax liabilities, benefiting partnerships with quicker financial insights.


3. Impact on Smaller Partnerships

Smaller partnerships, particularly those not previously covered under the MTD for Income Tax, might find these updates challenging. The cost and effort of transitioning to a fully digital system can be significant for smaller entities. However, HMRC provides resources and guidance to support all businesses through this transition, ensuring they understand and can fulfill their new obligations.


Navigating the New SA104 Form Requirements


1. Utilizing Digital Resources

Partners should take full advantage of the digital tools provided by HMRC. These include online tutorials, webinars, and digital record-keeping software guides. Leveraging these resources can ease the transition and ensure that partnerships remain compliant with the new regulations.


2. Consulting with Tax Professionals

Given the complexities and the potential penalties for non-compliance, consulting with tax professionals or accountants is advisable. These experts can provide tailored advice and ensure that the partnership’s tax returns are prepared accurately under the new system.


3. Planning for Financial Changes

Partnerships should review their financial management practices to accommodate the new tax reporting structure. This might involve revising financial planning strategies, especially around tax payment deadlines and cash flow management, to align with the digital submission timelines.


The 2024 updates to the SA104 form represent a significant shift towards a more digital and efficient tax system in the UK. While these changes aim to enhance accuracy and ease of compliance, they require businesses, especially partnerships, to update their practices and embrace digital solutions. By staying informed and proactive, partnerships can navigate these changes effectively, ensuring compliance and optimizing their tax management strategies.
