What is HMRC Form SA402?
HMRC Form SA402 is a document used in the United Kingdom for tax purposes. Specifically, it is used to register a partner for Self-Assessment when that partner is not an individual, such as a company or trust. The person responsible for the partner, like the trustee or company secretary, should sign the form. The form can either be used online or filled in on-screen, printed and posted to HMRC. If users encounter problems with the online forms, a PDF version is available to print and fill in by hand.

The Digital Shift in 2023
Significant changes to the form have been introduced in 2023 as HMRC shifts towards a 'digital by default' approach. The HMRC is contacting taxpayers who previously filed paper Self-Assessment tax returns to inform them that they will need to call HMRC if they require a paper form. The SA forms, including SA402, are no longer available to download from the gov.uk website.
However, it's important to note that not all paper filers will be contacted. Those aged 70 or over who have not previously submitted digitally, along with visually impaired filers, will continue to receive a paper SA return automatically.
Deadlines and Digital Filing
With this shift, the deadlines for filing have also changed. Self-Assessment returns submitted online have a filing deadline of 31 January following the tax year end, while paper returns normally need to be filed by 31 October following the tax year-end. From 6 April 2023, the paper form for the SA return will no longer be available to download from HMRC's website.
Broader Changes and Impact
The changes to form SA402 and the broader shift to digital filing are part of a wider campaign to move more taxpayers' interactions with HMRC to digital channels. The HMRC has already trialed using SMS replies for direct queries from its phone helpline during the run-up to the Self-Assessment deadline in January. In addition, HMRC will be reducing its use of high-volume letters and forms, with more of these being delivered digitally over the next two years.
How to Fill HMRC Form SA402 in the UK
Filling out the HMRC Form SA402 might seem daunting, but with the right guidance, you can complete it with confidence. The form is used to register a partner who is not an individual for Self-Assessment in the UK.
Preparing to Fill Out the Form
Before you begin filling out the form, gather all the necessary information you'll need, as the online version of the form does not allow you to save a partly completed form1. You can fill out the form using the online service or by hand if you print the PDF version1. If you're using an older browser, ensure you update it or use a different browser. The form should open in Adobe Reader.
Who Should Fill Form SA402?
The form should be filled and submitted by the person responsible for the partner, such as the trustee or company secretary. This person might be a partner in the other partnership. Remember to include the registration number on the form if the new partner is a limited liability partnership or limited company.
Filling the Form
Form SA402 registers non-individual partners in a partnership. This could be another partnership or a company. Individual partners register with form SA401.
Yes, a limited company can be a partner in a partnership, and it will need to include any income earned from the partnership when calculating its profits for the Company Tax Return.
Tax Returns and Partnerships
In a partnership, each human partner is responsible for their own Self-Assessment tax return, and paying their income tax and National Insurance contributions. Each partner that is another entity (like a limited company or another partnership) must submit its own tax return which includes its share of any profits from the partnership.
The partnership itself must also submit a tax return, and the nominated partner is responsible for this. The main partnership tax return must detail the share of profits or losses for each partner, using the partnership statement. Each partner should receive a copy of this statement to complete their own tax return.
What Happens If the Partnership Ends?
If a partner leaves a partnership, they still need to submit a tax return for that year, up until the date they left. If the partnership ends, the tax return is completed for the period of trading up until the date the partnership ended.
Keeping Records in Business Partnerships
You must keep partnership records for five years following the 31st January deadline of the partnership tax return. This applies whether you complete a paper tax return or an online one. The records you need to keep depend on the type of gains and income the partnership receives. Failure to maintain the correct business records could result in a penalty or fine.
In conclusion, filling out the HMRC Form SA402 involves several steps, from preparation to submission. With careful attention to detail and thorough record-keeping, you can successfully register a non-individual partner for Self-Assessment.
In conclusion, HMRC Form SA402 is an essential tool for registering non-individual partners for Self-Assessment in the UK. While the form's purpose remains the same in 2023, the shift towards digital filing and the changes to form availability and submission deadlines reflect HMRC's broader move towards 'digital by default services. It's essential for taxpayers to be aware of these changes to ensure their tax obligations are met accurately and on time.

Understanding the Complexity of Form SA402

They can also assist with the partnership's own tax return, which the nominated partner is responsible for.
Guidance in Case of Partnership Changes
Changes in a partnership, such as the departure of a partner or the dissolution of the partnership, can complicate tax matters. A tax accountant can guide you through these scenarios, ensuring that all partners fulfill their tax obligations for the period of their involvement in the partnership.
