Knowing the Basics: Limited Company vs Sole Trader

It is best to define what each of the business structures means before getting into the details.

What Is a Limited Company?

A limited company is an independent legal entity of its owners. Its debts and obligations are liable to the company itself. As a result, your individual assets are safeguarded.

To set up a limited company, one must be registered with Companies House. You will have to submit yearly accounts and confirmation statements. Moreover, you must meet additional regulatory requirements compared to sole traders.

A limited company is run by directors and owned by shareholders. In many cases, the owners of small businesses are the only shareholders and directors.

What Is a Sole Trader?

The easiest business structure in the UK is a sole trader. Basically, there is no separation of you and your business. You are running your business as a sole proprietorship and retain all after-tax profits. When choosing between a limited company vs sole trader, most businesses start as a sole trader because of its ease.

Sole trader registration is easy. It is just a matter of registering with Self Assessment at HMRC. No complicated paperwork is required. Besides, you begin trading almost instantly. Yet, there are serious implications of this simplicity. You are personally liable for all business debts. Moreover, no legal distinction exists between you and your business.

What are the Key Differences Between a Limited Company vs Sole Trader

Understanding the key differences helps you make an informed decision.

Liability and Structure

The greatest disparity in legal liability between a limited company vs sole trader is immense. If you are a sole trader, you own all the liability. Creditors can claim your personal property in case your business goes under. Your house, savings and any other property are at risk.

Conversely, a limited company vs sole trader has limited liability protection. The personal finances of the company and yours are different. As a rule, you are only liable for any unpaid shares. This difference is important in risk management in business, as stipulated by HMRC guidelines.

Tax Implications

The two structures, limited company vs sole trader, have significant differences in terms of tax treatment.

All profits are subject to Income Tax by Sole Traders. For the 2025/26 tax year, rates are:
- Personal Allowance: £12,570 (0%)
- Basic rate: 20 per cent on income that falls between £12,571 and £50,270.
- Higher rate: 40 per cent on incomes of £50,271 to £125,140.
- Additional charge: 45 per cent on income exceeding £125,140.

There will also be Class 2 and Class 4 National Insurance contributions. Class 4 NICs are 6% on profits between £12,570 and £50,270, and then 2 per cent above that.

Profits are taxed by Limited Companies. The existing Corporation Tax is 25% on profits exceeding £250,000. The rate of small profits is 19% on profits up to £50,000. Between £50,000 and £250,000, there is marginal relief of profits.

Also, you are paying Income Tax on your salary and dividends. Dividend allowance will be £500 in 2025/26. Dividend tax rates are:

Basic rate: 8.75%
Higher rate: 33.75%
Additional rate: 39.35%

Thus, you can lower your overall tax liability by strategic planning of salary and dividends.

Administrative Requirements

Limited company vs sole trader, the administrative responsibilities of sole traders are low. Only a self-assessment tax return is required each year. The requirements for recordkeeping are not very complicated.

On the other hand, limited companies have more complicated tasks:

Annual reports submission to Companies House.
A confirmation statement is submitted every year.
Corporation tax filing with HMRC.
Shareholder records and director records are kept in order.
PAYE and payroll requirements in case you are employing some staff.

Therefore, compliance is managed by accountants who are hired by many limited company owners.

Privacy and Public Information

In comparison with a limited company vs sole trader, business finances are quite confidential for a sole trader. Income is reported to HMRC, but this information is not publicly available.

But the limited companies are required to submit accounts to Companies House. These become public records. Moreover, the information about the directors is also publicly available. These are your name, year of birth, nationality and service address.
