The partners in the old partnership remain liable for its debts, but the new partner is not liable for old debts. The partners in the old partnership have the right to use partnership property to pay outstanding debts, and to split what remains between themselves in accordance with the partnership agreement.

Do you need to inform HMRC that a partner has joined?

Partners are responsible for paying their own income tax and National Insurance contributions. New partners must register for Self Assessment. You don't need to tell HM Revenue & Customs (HMRC) that a partner is joining unless the partnership is VAT-registered.

If your partnership is VAT-registered you must tell HMRC when a partner joins or leaves within 30 days - you can be fined if you do not. Provide partnership details when you register for VAT.

It is advisable to tell your solicitor and your accountant of any changes to a partnership, and the partnership's bank should be informed if there are any guarantees provided by the partners.

Reporting changes to limited partnerships

For limited partnerships and limited liability partnerships (LLPs), you need to inform Companies House when a member joins or leaves. For more information, see running a company or partnership and reporting changes to Companies House.

Retiring partners are entitled to remove their capital from the business. As a result, the profits may be split among the remaining partners unless they continue to use the retiring partner's partnership property.

If the nominated partner dies, the partnership must nominate another partner and tell HM Revenue & Customs (HMRC) as soon as possible. If they do not, HMRC will nominate one and write to the partnership. That partner must then complete any outstanding partnership tax returns.

See more on bankruptcy.

The partners in the old partnership will be able to split what remains - if anything - between themselves in accordance with the partnership agreement.

In many instances, including the permanent mental incapacity of a partner, you can apply to a court to have the partnership ended.

If the partnership is ended because of fraud committed by one partner on the others, the defrauded partners are entitled to keep the defrauder's share of the partnership capital as security against any future debts of the partnership.

If partnership property has increased in value during the period of the partnership, the assets may be subject to Capital Gains Tax. See business assets and Capital Gains Tax.
