Partnership tax returns may seem complex but getting them wrong can be costly. Late filing penalties start immediately after the deadline and apply to every partner, individually. Inaccurate returns can trigger investigations and additional penalties. Understanding the key requirements therefore not only protects your business, but it also ensures that you meet your legal obligations, whilst avoiding unnecessary costs.
What is a partnership tax return
A partnership tax return is a formal declaration of your partnership’s financial activity during a tax year. Using form SA800, partnerships must report income, expenses, profits and losses to HMRC.
Partnerships are transparent for tax purposes, meaning the partnership itself doesn’t pay tax. Instead, each partner/member is individually taxed on their allocated share of profits. While the partnership files the SA800 return, each partner must also report their share of profits/losses on their individual self-assessment return.
Which partnerships need to file
All UK partnerships operating for profit must file a partnership tax return, including general partnerships, limited partnerships, and Limited Liability Partnerships (LLPs). This requirement applies regardless of whether or not the partnership made a profit during the tax year.
Filing responsibilities and deadlines
When HMRC issues a notice to file, it may be addressed to the partnership or a named partner. If sent to the partnership, the nominated partner completes the return. If issued to a named partner, that individual is responsible.
For partnerships with only individual partners, paper returns must reach HMRC by 31st October following the tax year end, or 31st January for electronic returns. If HMRC issues the notice after 31st July, you have three months to submit, or until 31st January for electronic filing if later.
Partnerships with only corporate partners have nine months for paper returns and twelve months for electronic returns. Mixed member partnerships face more complex deadlines depending on their accounting date.
Late filing results in penalties for each partner, making timely submission even more crucial.
Essential information for your return
The SA800 requires detailed financial information about your partnership’s activities. Key elements include trading and professional income, business expenses, capital allowances, investment income, UK property income, foreign income, and capital gains or losses from asset disposals.
The partnership statement is crucial, listing each partner’s name, address, tax reference, and their allocated share of profits, losses, and other income.
Supplementary pages and accounts
Many partnerships require additional supplementary pages beyond the basic SA800 form, covering areas like UK property, foreign income, and asset disposals, to name a few.
Partnerships with annual turnover exceeding £15 million must submit full accounts with their return. Others may choose to submit accounts voluntarily to support the figures reported on the partnership tax return.
Mixed member partnerships
Partnerships with both individual and corporate partners face additional complexity. Profits allocated to individual partners must follow income tax rules, while corporate partner profits follow corporation tax rules. Anti-avoidance rules may also apply to prevent artificial profit shifting.
As part of the partnership tax return completion, disclosure notes are required on the return where the figures reported on the return (usually profits/losses) are different when computed under the income tax basis and corporation tax.
Individual partner obligations
Each partner must report their allocated profit share on their individual self-assessment return. Individual partners pay income tax and National Insurance contributions, while corporate partners pay corporation tax.
Recent changes
From 2024-25, partnerships report trading income for accounting periods ending in the tax year, but individual partners calculate trading income on a tax year basis. The cash basis is now the default method for calculating trading profits.
Maintaining compliance
Accuracy is essential, as HMRC can impose penalties for errors. Maintaining good records throughout the year and seeking professional advice when needed helps avoid issues. If you discover errors in a submitted return, correct them promptly through HMRC’s amendment process.
Planning considerations
Understanding profit allocation and timing can optimise tax efficiency. Partnership draws and profit allocations affect individual partners’ tax positions, and changes in partnership composition during the year create additional complexity.
Partnership taxation continues to evolve, with Making Tax Digital for partnerships postponed indefinitely but expected eventually. Staying informed about developments and maintaining good compliance practices protects your business and ensures you meet all legal obligations.
