Partnerships
1 Introduction
A partnership is a single trading entity, but for taxation purposes each individual partner is effectively treated as trading in his own right and is assessed on his or her share of the tax adjusted trading profit of the partnership.
It is essential to understand therefore that it is not the partnership itself that is assessed upon its tax adjusted trading profit, but it is each individual partner who will be assessed on his or her share of that tax adjusted trading profit.
Partners are assessed on a tax year basis - the same as sole traders.
2 Trading income
The default method of calculating the trading profit of the partnership is the CASH BASIS although the partnership can elect for the ACCRUALS BASIS to apply.
The partnership’s tax adjusted profits or loss for an accounting period (after capital allowances for the partnership) is computed in the same way as for a sole trader.
Partners’ salaries and interest on capital debited on the statement of profit or loss are not deductible as expenses as these are simply an allocation of trading profit by the owners of the business. These must be added back in the adjusted profits computation.
3 Allocation of the trading profit or trading loss
The adjusted trading income or trading loss is divided between the partners according to their profit sharing arrangements in force during the accounting period.
Partners may firstly be entitled to salaries and interest on capital (known as 'prior appropriations of profit'). The balance of any trading profit (or loss) remaining will then be allocated in the profit sharing ratio (PSR).
4 A change in the profit sharing agreement
If the profit sharing agreement is changed during a period of account, the profit must be time apportioned before allocation under the different agreements.
Doug and Rob are in partnership. The trading income for the year ended 30 September 2025 was £18,000
Up to 30 June 2025 profits were shared between Doug and Rob 3:2, after paying salaries of £3,000 and £2,000 respectively per annum.
From 1 July 2025 profits were shared 2:1 after paying salaries of £6,000 and £4,000 respectively per annum.
Show the allocation of trading profits for the year ended 30 September 2025.

5 Partnership capital allowances
Capital allowances are deducted as normal in calculating the tax adjusted trading profit.
If assets are used privately by the partners, then as for a sole trader only the business proportion is included in the capital allowances computation.
6 Partnership losses
Losses are allocated between partners in the same way as profits.
Loss relief claims available are the same as for sole traders and each partner may choose their own preferred use of their loss.
Partners continuing in a partnership will be able to claim to carry forward their loss, or to set off against total income of current and/or preceding tax years and thereafter extend against chargeable gains.
A partner joining the partnership may also choose to claim under opening years loss relief for losses in the first four tax years of his membership of the partnership.
A partner leaving a partnership may choose to claim under terminal loss relief.
Will and Grace are in partnership, sharing profits and losses equally after paying a salary to Will of £18,000 p.a. For the year ended 31 March 2025 the partnership had a trading loss of £30,000.
Total £ | Will | Grace | ||
Trading loss | (30,000) | |||
Salary to Will | (18,000) | 18,000 | ||
Balance | (48,000) | |||
Shared equally | (24,000) | (24,000) | ||
Trading loss | (30,000) | (6,000) | (24,000) |
The proforma for adjusting profits and capital allowances are the same for sole traders and partnerships and therefore in Section B or C of the exam you may have to adjust profits for a partnership in part (a) and then allocate the profits after salaries etc in part (b). Alternatively you may have to complete a full capital allowances computation for a partnership.
Losses, allocation of profits/losses may be examined anywhere in the exam. In a section A MCQ it might look as follows:
