The differences between Sole Tradership and a Limited Company

Each structure has advantages and disadvantages which are outlined below to help you choose the best option for your circumstances.


A limited company is its own legal identity, so as a shareholder your liability is limited (hence the name 'limited by shares').

As a sole trader, there is little distinction between you and the business. Any business debts become your debts and your personal assets - including your house - are not protected.


In a limited company, tax is deducted from directors' salaries via PAYE and paid at regular intervals to HMRC. If applicable, higher tax rate is paid by shareholders on dividends under the self-assessment regime. Corporation tax is payable 9 months after the year end, by filing a company tax return.

Sole traders pay tax on their business profits, after expenses have been deducted, via the self-assessment tax return system. The deadline for online tax returns is 31st January after the end of the tax year.

National Insurance

Within a limited company, both employer's and employee's National Insurance is payable on directors' salaries and bonuses. This NI charge is greater than that paid by a sole trader/partner, who pay Class 2 NI contributions of £2.75 per week and Class 4 contributions dependent on profits in excess of £7,956 (rates accurate for 2014/15).

Profit and Loss

For limited companies, tax is charged at 20% for profits up to £300,000 and 21% over £300,000. For a sole trader/partnership, profits are taxed at 40% on taxble income in excess of £31,865 and 45% over £150,000 (rates accurate for 2014/15).

In a limited company, losses can only be carried forward and set against future profits or set against the previous year's profits. For sole traders, losses can be set off against other income or carried back to previous years.

Filing Accounts

A limited company must prepare annual accounts (also known as 'statutory accounts') from the company's records at the end of the financial year. These are to be filed with HMRC as part of your tax return as well as sent to all shareholders and Companies House. A limited company must also file an Annual Return to HMRC, which includes information about the directors, shareholders and registered office.

Sole traders/partners are not legally required to have annual accounts to or file accounts for inspection. However, a record of business expenses and personal income are required for tax returns.


An incorporated company, whilst not guaranteeing reliability, gives the impression of a soundly based organisation and may appear more credible. In certain sectors, contractors or agencies may not work with sole traders because of the legal protection a limited company provides.
