Choosing whether to operate as a sole trader or set up a limited company is one of the first decisions you’ll make when starting a business. Both business structures have advantages and disadvantages, and the right choice depends on factors such as the level of financial risk you’re prepared to take, how you want to be taxed and the amount of administration you’re willing to manage. This guide compares the key differences to help you decide which option is right for your business.
Sole trader vs limited company: What’s the financial risk?
When deciding between a sole trader business and a limited company, one of the most important differences to consider is your personal financial liability.
As a sole trader, you and your business are legally the same entity. This means you’re personally responsible for the business’s debts and other liabilities. If the business can’t meet its financial obligations, your personal assets, including your savings and potentially your home, could be at risk.
A limited company is a separate legal entity from its owners. This means the company is generally responsible for its own debts and liabilities.
If you’re a director or shareholder, your personal financial risk is usually limited to the amount you’ve invested in the company. However, there are exceptions. For example, you may still be personally liable if you:
- provide a personal guarantee for a business loan or other borrowing;
- trade fraudulently or wrongfully; or
- fail to meet certain legal duties as a company director.
For many business owners, the additional legal protection offered by a limited company is an important reason for choosing this business structure.
Sole trader or limited company: Tax and National Insurance
The way you pay tax depends on whether you operate as a sole trader or through a limited company.
As a sole trader, you pay Income Tax and, where applicable, National Insurance contributions on your business profits. These are usually paid through Self Assessment.
A limited company pays Corporation Tax on its taxable profits. If you’re a company director, you’ll normally pay tax on any salary or dividends you receive from the company. Depending on how you’re paid, you and the company may also have National Insurance obligations.
The most tax-efficient business structure depends on your circumstances, including your level of profits, how much income you need to take from the business and your future plans. Tax rules also change regularly, so it’s worth reviewing your position as your business grows.
Which business structure is more tax-efficient?
There isn’t a single answer to this question. The most tax-efficient business structure depends on your individual circumstances.
As a sole trader, you pay Income Tax and, where applicable, National Insurance contributions on your business profits.
With a limited company, the company pays Corporation Tax on its profits. As a director, you can choose how to take money from the business, typically through a combination of salary and dividends. Depending on your circumstances, this may or may not be more tax-efficient than operating as a sole trader.
Tax is only one factor to consider when choosing a business structure. You should also think about your level of financial risk, the amount of administration involved and your plans for growing the business.
If you’re unsure which option is right for you, it’s worth seeking professional advice based on your expected profits and personal circumstances.
Sole trader or limited company? What’s the administrative burden?
A sole trader generally has fewer administrative responsibilities than a limited company.
As a sole trader, you’ll need to:
- keep accurate business records;
- complete a Self Assessment tax return each year; and
- pay any Income Tax and National Insurance due.
A limited company has additional legal and reporting responsibilities. These typically include:
- keeping company accounting records;
- preparing annual accounts;
- filing a Corporation Tax Return with HMRC;
- submitting annual accounts and a confirmation statement to Companies House; and
- meeting any PAYE obligations if the company pays salaries.
Because of these additional requirements, many company directors choose to use an accountant or bookkeeper to help manage the company’s financial records and statutory filings. Sole traders may also use professional support, although their reporting requirements are generally simpler.
Sole trader or limited company: What if you want business partners or employees?
A sole trader is owned and run by one person. If you want to start a business with other people, you could either:
- set up a limited company, with two or more shareholders and directors; or
- form a partnership, where the partners share responsibility for running the business.
An ordinary partnership is generally quite simple to establish, but each partner is personally responsible for the partnership’s debts. If limiting personal liability is important, you could consider a limited liability partnership (LLP) or a limited company.
Whether you operate as a sole trader or through a limited company, you can employ staff. If you do, you’ll need to operate a PAYE payroll, deduct Income Tax and National Insurance from employees’ pay where required, and pay employer National Insurance contributions where applicable.
