Winding up a business partnership involves HMRC notifications, a final partnership tax return, and often Capital Gains Tax on assets split between partners. This guide explains the tax and legal steps, and the Partnership Act 1890 rules that apply when there is no written agreement.
Notifying HMRC and the Final Return
Dissolving a partnership requires a final partnership Self Assessment return covering the period up to cessation, with each partner reporting their share of the final period's profit or loss on their own personal Self Assessment return. If the partnership was VAT registered, deregistration must also be completed within the applicable time limit, and any PAYE scheme for partnership employees must be closed down correctly.
Capital Gains Tax on Partnership Assets
Where partnership assets such as property, goodwill or equipment are sold or distributed to partners as part of winding up the business, each partner is generally treated as disposing of their proportionate share of the asset, based on the partnership's profit-sharing ratio, which can trigger a Capital Gains Tax liability using the £3,000 annual exempt amount and 18%/24% rates for 2026/27, unless a specific relief such as gift hold-over relief applies.
The Partnership Act 1890 Default Rules
Where partners have no written agreement covering what happens on dissolution, the Partnership Act 1890 fills the gap: for an ordinary partnership, any partner can generally dissolve the partnership, partnership assets must be used first to repay debts, then to return partners' capital, with any remaining surplus shared according to the agreed profit-sharing ratio. A written partnership agreement can override these default rules if it addresses dissolution directly.
Debts and Joint Liability
In an ordinary partnership, partners remain jointly and severally liable for debts incurred while the partnership was trading, meaning a creditor can pursue any individual partner for the whole amount even after the partnership has dissolved, until those debts are settled. A Limited Liability Partnership (LLP) is a separate legal entity and follows a more formal, insolvency-style winding-up process rather than this simpler dissolution route.
Frequently Asked Questions
What happens for tax purposes when a partnership dissolves?
Dissolution ends the partnership as a tax entity. A final partnership tax return must be filed covering the period up to cessation, each partner's share of profit or loss for that final period is reported on their own Self Assessment return, and HMRC must be notified that the partnership has ceased.
How do I notify HMRC that a partnership has dissolved?
You notify HMRC through the partnership's final Self Assessment partnership return, and individual partners should also update their own Self Assessment records if they are no longer self-employed as a result. If the partnership was VAT registered, you must also deregister for VAT within the required timeframe.
Does dissolving a partnership trigger Capital Gains Tax?
It can. If partnership assets (such as property, goodwill or equipment) are distributed to partners or sold as part of the dissolution, each partner is generally treated as disposing of their share of those assets for Capital Gains Tax purposes, based on their partnership profit-sharing ratio, unless a specific relief applies.

What is the Partnership Act 1890 default position?
Where partners have no written partnership agreement covering dissolution, the Partnership Act 1890 sets default rules: for example, any partner can generally dissolve an ordinary partnership at will, and assets are applied first to pay debts, then to repay partners' capital, with any surplus shared according to the partners' profit-sharing ratio.
Can a written partnership agreement change what happens on dissolution?
Yes -- a partnership agreement can set out its own rules for what happens if a partner leaves, retires, dies, or the partnership is wound up, including how assets are valued and split, and these terms generally override the 1890 Act default rules where the agreement addresses the point.
What happens to partnership debts when it dissolves?
In an ordinary (general) partnership, partners are jointly and severally liable for partnership debts, meaning creditors can pursue any partner for the full amount owed, even after dissolution, until debts existing at the time of dissolution are settled.
Is a Limited Liability Partnership (LLP) dissolved differently?
Yes -- an LLP is a separate legal entity from its members, so winding it up follows a different, more formal insolvency-style process (such as a members' voluntary liquidation if solvent) rather than the simpler dissolution process that applies to an ordinary partnership.
Do I need to deregister the business name and any registrations?
Yes -- alongside HMRC notifications, you typically need to deregister for VAT if registered, close PAYE schemes if the partnership employed staff, and settle any final business rates, licences or registrations tied to the partnership, in addition to the Self Assessment steps.
