Sole trader vs limited company at £50K: the 2026/27 comparison
At £50,000 profit, the worked example below leaves the sole trader about £1,406 ahead after tax. Your withdrawals, pensions and business needs can change the decision.
Start with the same profit and assumptions
Compare business profit before the company pays a director's salary or employer National Insurance, rather than comparing turnover with take-home pay. Turnover is sales before expenses. Profit is what remains after the business expenses used in the comparison.
This example assumes an individual taxed at England's rates, below State Pension age, with no other income, student loan, pension contribution, benefits or special reliefs. The company has one director, who is its only employee, and no Employment Allowance. It pays a £12,570 annual salary and distributes all remaining post-tax profit as a dividend. It has a full twelve-month accounting period, no associated companies and no other income affecting Corporation Tax. Both routes start with the same business profit and exclude differences in professional fees and running costs.
The salary is a fixed assumption to make the calculation clear, rather than a recommendation for every director. Scotland has different rates for non-dividend income. Changing these facts can change the answer.
The maths at £50,000 profit
Sole trader
The £12,570 Personal Allowance leaves £37,430 taxed at 20%, giving £7,486 of Income Tax. Class 4 National Insurance, the self-employed contribution on profits, is 6% of the same £37,430, or £2,245.80. That gives a combined £9,731.80 and £40,268.20 after these taxes.
At this profit level Class 2 is treated as paid without a separate contribution. It has not disappeared in every situation; voluntary contributions can still matter at low profits. Check Income Tax rates and self-employed National Insurance.
Limited company and director
Employer National Insurance is 15% of the £7,570 salary above the £5,000 annual secondary threshold, giving £1,135.50. The salary and employer contribution leave £36,294.50 taxable company profit. At 19%, Corporation Tax is £6,895.955 before rounding, leaving £29,398.545 for a dividend.
The £500 dividend allowance leaves £28,898.545 taxed at 10.75%, or £3,106.5935875 before rounding. Adding employer National Insurance, Corporation Tax and dividend tax gives £11,138.0485875, displayed as £11,138.05. Salary plus net dividend leaves £38,861.95. Actual returns and payroll calculations use their required rounding rules.

Selected profit levels using the same method
| Business profit | Sole-trader tax | Company and director tax | Lower tax at this sample |
|---|---|---|---|
| £40,000 | £7,132 | £8,367 | Sole trader £1,235 |
| £50,000 | £9,732 | £11,138 | Sole trader £1,406 |
| £60,000 | £13,889 | £13,909 | Sole trader £20 |
| £70,000 | £18,089 | £18,958 | Sole trader £869 |
| £80,000 | £22,289 | £24,235 | Sole trader £1,947 |
Figures are rounded to the nearest pound after calculation. The company column includes employer National Insurance and personal dividend tax. These five sample points do not prove that the sole trader wins at every profit between them. The lines come close near £60,000, and small crossover intervals can occur under these assumptions. A saving of a few pounds is easily outweighed by different running costs.
Why current rates need to be included
The company calculation needs the 15% employer contribution and current dividend rates. Using the former 13.8% employer rate understates its cost. For 2026/27 the dividend basic and higher rates are 10.75% and 35.75% above the allowance, with 39.35% at the additional rate.
The ordinary small-profits Corporation Tax rate is 19% up to £50,000, with 25% above £250,000 and marginal relief between the limits. Marginal relief reduces the main-rate bill for eligible companies between those limits. The thresholds reduce for short periods and associated companies, meaning companies under common control. Do not apply an automatic 19% to every pound without checking the marginal-relief rules.
Employment Allowance eligibility also matters. The company in this example cannot claim because its only director is the only employee liable for employer National Insurance. A second worker does not automatically establish every eligibility condition.
What can change the decision?
Retained profit and pensions
Leaving profit in the company can postpone the personal tax on a later dividend, but that tax is deferred rather than automatically removed. Compare the money you need personally with the money the business can retain.
An employer pension contribution can change both the company profit and the amount withdrawn personally. Deductibility depends on the business-purpose rules, and pension allowances and restrictions need their own check. Personal pension contributions have different relief mechanics. Compare the same gross pension funding and personal cash needs; do not mix the net cost of one route with a gross contribution on the other. See HMRC's employer pension deduction guidance.
Liability, contracts and ownership
A sole trader is personally responsible for business debts. A company is a separate legal person, but a personal guarantee or a director's own obligations can still create personal exposure. Check the contract, insurance and director duties rather than assuming a company removes every risk. The government's business-structure guide explains the basic distinction.
Check what your actual customers and contracts require. Do not assume that every healthcare or contracting role needs a company or that incorporation changes the employment-status rules. A company can also make it possible to issue shares to investors, which is a separate commercial reason to consider it.
A future sale
Business Asset Disposal Relief, a reduced Capital Gains Tax rate for eligible disposals, is 18% for qualifying disposals from 6 April 2026. It can apply to qualifying sole-trader businesses as well as eligible company shares. The conditions differ, so it is not a tax benefit reserved to incorporation. See the eligibility rules.
Making Tax Digital is a separate test
Making Tax Digital for Income Tax means digital business records and quarterly updates through compatible software, followed by the required annual return. The April 2026 entry test uses qualifying gross self-employment and property income over £50,000 in 2024/25, subject to exemptions. That is different from £50,000 profit in this example. Check whether and when the rules apply.
Allow for each structure's software, bookkeeping, accounts and filing costs, along with the cost and consequences of changing structure. There is no requirement to form a company simply because you come into digital reporting.

Frequently asked questions
Does a limited company save tax at £50,000 profit in 2026/27?
In this illustrative full-extraction example, the sole trader pays about £9,732 and the company route about £11,138, a difference of £1,406. The company uses a £12,570 salary, pays employer National Insurance and cannot claim Employment Allowance. Different salaries, other income, pensions, retained profit and costs can change the result.
Is the £50,000 figure turnover or profit?
This tax comparison starts with £50,000 of business profit before the director salary and employer National Insurance. Turnover means sales before expenses. The income test for Making Tax Digital uses qualifying gross self-employment and property income, not this profit figure.
Can a single-director company claim Employment Allowance?
If the company has only one director and that director is the only employee liable for secondary Class 1 National Insurance, it cannot claim. A different staffing position needs a full eligibility check; another employee does not automatically guarantee an allowance.
Is there one profit level at which everyone should incorporate?
No. The tax comparison changes with how much profit is withdrawn, salary, other income, pension contributions, associated companies and available reliefs. Small differences around a crossover can be outweighed by the extra running costs. Compare your own figures and commercial reasons.
Does Making Tax Digital require me to form a company?
No. Making Tax Digital changes record-keeping and reporting for people in scope. The April 2026 entry test uses qualifying income over £50,000 in 2024/25, subject to exemptions. Incorporating is a separate decision with its own tax, reporting and legal consequences.
