Partnership vs Limited Company 2026/27: Splitting Profit Between Two Owners

Two ways to share a business

When two people own a business together, the legal structure shapes the tax. The two common choices are a general partnership and a limited company with two shareholder-directors. They are taxed in completely different ways, and the better option depends on profit level and how much cash you take out.

How a partnership is taxed

A general partnership is transparent for tax. The partnership itself pays no tax; instead each partner is taxed on their share of the profit through their own Self Assessment.

Each partner gets their own Personal Allowance of GBP 12,570, their own basic-rate band to GBP 50,270 at 20% income tax, and pays Class 4 NI at 6% on profit between GBP 12,570 and GBP 50,270, then 2% above. Partners can agree any profit-sharing ratio, ideally documented in a partnership agreement.

How a two-owner company is taxed

A limited company is a separate legal person. It pays Corporation Tax on its profit: 19% up to GBP 50,000, 25% from GBP 250,000, with marginal relief using the 3/200 fraction in between. The owners then extract money as salary, taxed under PAYE, and dividends, taxed under the dividend rules with a GBP 500 allowance each then 10.75% at basic rate.

A worked example

Say the business makes GBP 80,000 of profit, split equally between two owners.

As a partnership, each partner has GBP 40,000 of profit:

• First GBP 12,570 is covered by the Personal Allowance, so no income tax.
• The remaining GBP 27,430 is taxed at 20% income tax.
• Class 4 NI at 6% applies to profit between GBP 12,570 and GBP 40,000.

Both partners sit comfortably below the GBP 50,270 higher-rate threshold, so all their taxable profit is taxed at basic rates, and they use two full Personal Allowances directly.

As a company, the GBP 80,000 profit faces Corporation Tax first. With profit above GBP 50,000, part is taxed at 19% and part attracts marginal relief on the way to 25%. Whatever is left can be paid out as dividends, each owner using a GBP 500 dividend allowance then paying 10.75% dividend tax at basic rate. The double layer of Corporation Tax then dividend tax is the trade-off for the company's flexibility.

Choosing between them

• A partnership is simpler, cheaper to run and uses two Personal Allowances and basic-rate bands directly.
• A company can retain profit taxed only at Corporation Tax rates, useful if you do not need all the cash, and offers limited liability.
• Companies suit owners who want to leave money in the business or plan around dividends; partnerships suit owners who draw most of the profit each year.
• Remember partners are personally liable for the business's debts, unlike company shareholders.

The bottom line

For two owners drawing most of their profit at modest levels, a partnership often wins on simplicity and twin allowances. As profits grow and owners want to retain cash or cap personal liability, a company's structure can pull ahead despite the extra layer of tax.
