Choosing between operating as a sole trader or forming a limited company is one of the most significant business decisions for Amazon sellers. Each structure has advantages and drawbacks that depend on your specific situation.
Sole Trader: Simple and Flexible
As a sole trader, you and your business are the same legal entity. Setting up is as simple as registering with HMRC for Self Assessment. There is no formal registration cost, no annual filing requirements beyond your tax return, and you keep all profits after tax.
You pay income tax on your profits at your personal tax rate (20%, 40%, or 45% depending on total income) plus National Insurance contributions. The tax calculation is straightforward — your Amazon profit is added to any other income on your tax return.
The main disadvantage is unlimited personal liability. If your business incurs debts or faces a legal claim, your personal assets (savings, property) are at risk. For a low-risk Amazon business, this may not be a major concern, but it is worth understanding.
Limited Company: Protection and Tax Efficiency
A limited company is a separate legal entity. It owns the business assets, enters into contracts, and is liable for its own debts. Your personal assets are generally protected from business liabilities (though directors can be held personally liable in some circumstances, like fraud).
The company pays Corporation Tax on its profits (currently 25% for profits above £50,000, with a lower rate for smaller profits). You take money from the company as a salary (subject to income tax and NI) and dividends (taxed at lower rates than salary). The combination of salary and dividends can be more tax-efficient than sole trader income tax at higher profit levels.
The disadvantages include more administration (annual accounts filed with Companies House, Corporation Tax returns, VAT returns if registered), higher accountancy costs (£1,000–£2,000+ per year compared to £300–£700 for sole traders), and less flexibility in accessing your profits.
The Crossover Point
The tax efficiency of a limited company typically becomes meaningful when annual profits exceed £30,000–£40,000. Below this level, the additional administration and accountancy costs often outweigh the tax savings. Above it, the difference becomes significant enough to justify the switch.
Your accountant can model both scenarios with your specific numbers to determine the optimal structure and timing for any transition.
Practical Considerations
Some wholesalers prefer to work with limited companies as it signals a more established business. Some Amazon sellers operate as limited companies for the professional image, even at lower profit levels. And if you plan to bring in a business partner or seek external investment, a limited company provides the necessary structure.
Making the Decision
Start as a sole trader if you are just beginning. The simplicity and low cost let you focus on building the business. As your profits grow and the tax implications become meaningful, discuss incorporation with your accountant. The transition is straightforward and can be done at any time.
