Sole trader: simple and flexible

You and the business are the same legal person. Profits are taxed through Self Assessment with Income Tax and Class 4 National Insurance. Setting up takes minutes, the admin is light and you can take money out whenever you like. The trade-off: you are personally liable for business debts.

Limited company: separate and structured

The company is its own legal entity. It pays Corporation Tax on profits — 19% on profits up to £50,000, 25% above £250,000, with marginal relief in between. Directors usually take a mix of salary and dividends. Your personal liability is generally limited to what you invest.

What changes the decision

• Profit level: at lower profits, the tax saving from a company is often small or disappears once extra costs are counted.
• Dividend tax: from April 2026 the ordinary and upper dividend rates rose to 10.75% and 35.75%, which narrows the gap for some owners.
• Risk: if you sign leases, employ staff or take on large contracts, limited liability matters more.
• Clients: some larger customers prefer or require working with a company.
• Admin: companies file annual accounts and a confirmation statement at Companies House, a Corporation Tax return and usually run payroll. Directors also need to verify their identity with Companies House.

A practical approach

Many owners start as sole traders and incorporate once profits are steady and they don’t need all the money they make. The right moment is a numbers question, not a feeling.

How we help

The 2026/27 numbers that matter

• Personal Allowance: £12,570, frozen until April 2031.
• Employer National Insurance: 15% on salary above £5,000 a year.
• Employee National Insurance: 8% on earnings above £12,570.
• Dividend Allowance: £500.
• Dividend tax: 10.75% basic rate, 35.75% higher rate and 39.35% additional rate.

Why a small salary helps

A salary is a business expense, so it reduces Corporation Tax, and it can count towards your State Pension record. Many directors set salary around the National Insurance thresholds. The best level depends on whether your company can claim Employment Allowance — a company where the director is the only employee usually can’t.

How dividends work

Dividends are paid from profits after Corporation Tax. You can only pay them if the company has enough retained profit, and each one should be backed by board minutes and a dividend voucher. They aren’t subject to National Insurance, which is where the saving usually comes from.

Things to plan for

• Personal tax on dividends is paid through Self Assessment, often months later. Put money aside as you go.
• The higher dividend rates from April 2026 mean last year’s plan may no longer be the best one.
• Pension contributions paid by the company can be an efficient alternative for money you don’t need now.

How we help

We work out your salary and dividend mix at the start of each tax year, run the director’s payroll, prepare the dividend paperwork and tell you how much to save for your tax bill.
