What is a limited company?

It is a type of legal framework for your business. Limited company:

  • unlike sole traders, it is legally separate from the people who run it
  • has separate finances and bank accounts
  • has shares and shareholders
  • can keep any profits it makes after paying tax or carry forward losses

Here, we'll look at how to form a limited company and its advantages and disadvantages.

What are the benefits of a Limited Company?

  • Credibility
    Enhance your business's credibility and potential consumer base with a limited company status. Unlike a sole proprietor, limited company registration exudes a sense of legitimacy and organisation.
  • Better tax implications
    Directors and shareholders of a private limited business can pay themselves through a PAYE salary, which can be added to stockholder dividends after paying corporation tax. Therefore, private limited companies may benefit from tax savings unavailable to sole traders.
  • Protect your company name
    When you register as a limited company, other businesses are prohibited from using your brand name or anything too similar to it.
  • Raise additional capital
    If your business is limited, you can raise money by selling shares. Because their risks are restricted to their shares' value, investors are protected from any business failure by owning shares.
  • Pension benefits
    Unlike those who operate a self-employed business, a limited corporation is permitted to deduct executive pension contributions from its operating costs.

What is the time required to set up a limited company?

Registering your business with Companies House online doesn't take much time. If you have everything prepared, you can complete the process in minutes, and registration is typically completed within 24 hours. Postal applications can take 8-10 days.

However, you might need additional time to complete the documentation beforehand. Having a business plan should assist you in organising your to-do list and let you know how much time you require to get going.

How to register a limited company?

You must first register your firm with Companies House and provide the required details to start a new Limited Company.

  • Company's full legal name and address
  • Directors' and secretaries' names and address
  • Information about the capital and shareholders

Before registering or incorporating your business, Companies House will review the documents and confirm their validity. It will then issue a Certificate of Incorporation that contains details like:

  • The company name and its registration number
  • Its date of incorporation
  • Business type, i.e. Private Limited by Shares

The company's registered office is in England, Northern Ireland, Wales, and Scotland.

How does the Limited Company tax calculator work?

UK limited company tax calculator determines corporation tax on profits, excluding any reliefs granted.

The effective corporate tax rate ranges between 19% to 25% beginning April 2023 (previously 19%). Businesses have no personal allowance, and hence, all profits are taxable. A firm's net taxable trading profit defines the rate of corporation tax you pay by corporation tax calculator .

Profit rangeMarginal rate

From £0 to £50,000


£50,001 to £249,999


£250,000 or more



Because of the profit tax, you must determine the net trading profit for the financial year. It may differ from the gain on your profit and loss statement since some things aren't included for corporation tax purposes—for instance, annual investment allowance and various depreciation rates.

Example 1

Suppose your limited company made £10,000 in sales and a £7,000 profit after paying £3,000 in expenses. At 19%, your corporate tax liability is £1,330.

Example 2

Now let's say an ltd company's profit is £75,000 for a given tax year beginning on or after o1 April 2023.

So we see an effective rate of 21.50% and a marginal rate of 26.5%—the £16,125 (£1,875 more than the 19% rate).

The effective rate of corporation tax at various profit levels from 01 April 2023 is:

This Effective Rate applies to the total profits; no slicing is needed.
