A partnership is a business which is owned and managed by more than one person. The partners are jointly responsible for all aspects of the business and will share the profits. Partnerships have a requirement to complete and submit a self-assessment tax return to HM Revenue and Customs (HMRC).

What is a partnership tax return?

There are two returns that must be completed for partnerships:

  • Partnership tax return

All partners are jointly responsible for the completion of the partnership tax return. The total partnership profits, losses and other income are allocated to the individual partners on the return according to their profit share entitlement.

  • Individual tax return

Each partner is responsible for the completion of his or her own individual tax return. They must complete the partnership pages from the details entered into the partnership return.

How do I complete a partnership tax return?

The key parts of the partnership return which need to be completed are:

How do I complete the partnership pages of my individual tax return?

In the individual’s return, a separate page must be completed for each partnership an individual belongs to. The key parts to complete are:

Box to be completedComments
Box 1 Partnership reference number and Box 2 Description of partnership trade or professionThe is the unique tax reference (UTR) of the partnership, for example 4564564564. An example of a trade or profession could be hairdressing. 
Boxes 3 and 4These boxes should only be completed if the individual has joined or left a partnership during the tax year. 
Boxes 6 and 7These are the dates that the accounting period of the partnerships starts and finishes. For example the year ending 31 December 2015 will start on 1 January 2015 and finish on 31 December 2015. If a partner has joined or left in a tax year, their basis period may be different. 
Box 8The figure here is the individual's share of the partnership profits. 
Box 9 If the individual has joined or left a partnership during the tax year, their basis period may not be the same as the partnership's accounting period. An adjustment (which may be positive or negative) may need to be made.
Box 20The individual's taxable profits are calculated after any adjustments and losses available. In many cases the figure will simply be the partner's share of profit for the accounting period.

How do I calculate the share of profits?

A partners share of profit is calculated in the following way:

  • Calculate the partnership profit

In the partnership accounts, expenses are deducted from the income to arrive at the profit. It is advisable to use the services of an accountant when calculating this. 

  • Business expenses

In order for expenses to be allowable for tax purposes they must be “wholly and exclusively” incurred for business purposes. 

  • Non business expenses

For tax purposes any expenses which are disallowed must be added back and this will increase the profit which is taxable.

  • Split the profit

The profit is split between the partners in accordance with their agreement. This may simply be an equal share to each partner.

How do I file my partnership tax return?

A partnership tax return can be filed online with HM Revenue & Customs (HMRC), but you will need to purchase commercial software in order to do this. The filing deadline is 31 January following the end of the tax year.

Alternatively, a paper form can be completed; the filing deadline is 31 October following the end of the tax year.
