There is no single answer for every Amazon seller. Many new Amazon businesses start as sole traders because it is simple and cost-effective. As profits grow, a limited company may become more tax efficient and provide additional legal protection. The best structure depends on profit levels, future plans and personal circumstances.
One of the first decisions every Amazon seller faces is whether to trade as a sole trader or operate through a limited company. Both can sell on Amazon, but the tax treatment, legal responsibilities and administration requirements are very different.
As a sole trader, you and the business are legally the same entity. This is the simplest business structure in the UK.
A limited company is a separate legal entity from its owners. It is registered with Companies House.
For a detailed comparison of both structures across all business types, see our comprehensive guide:
Limited Company or Sole Trader — Full GuideMost Amazon sellers begin as sole traders because it is the quickest and simplest way to start trading on the platform. Many start by selling a small number of products while maintaining employment elsewhere.
Simply register with HMRC as self-employed — no Companies House involvement.
Self Assessment tax returns are simpler and typically cost less than limited company accounts.
Fewer record-keeping obligations compared to a limited company.
One annual Self Assessment covers all your tax obligations.
Low commitment way to see if your Amazon products sell before investing further.
Your personal assets are at risk if the business runs into financial difficulty.
All profits are taxed as personal income with fewer options for tax optimisation.
Mixing finances can create bookkeeping problems and complicate tax compliance.
Raising external investment is more difficult as a sole trader.
Income Tax and National Insurance can become significant at higher profit levels.

Online Self Assessment Tax Return ServicesAs an Amazon business grows, many sellers transition from sole trader to limited company. Understanding when and why can help you plan your own business journey.
Your personal assets are generally protected if the business faces legal or financial difficulties.
Corporation Tax rates can be lower than higher-rate Income Tax, and salary/dividend planning can reduce your overall tax burden.
Directors and shareholders can choose how and when to extract profits from the business.
Limited companies are better suited to employing staff, raising finance and expanding internationally.
Suppliers, lenders and Amazon itself may view a limited company as more established.
Statutory accounts must be prepared and filed with Companies House each year.
A CT600 Corporation Tax return must be filed with HMRC alongside your annual accounts.
Confirmation statements and other filings are required to maintain your company registration.
Additional record-keeping requirements including director records, shareholder registers and board minutes.
Professional support is typically needed, though the tax savings often outweigh the fees.
A side-by-side comparison to help you understand the key differences at a glance.
| Feature | Sole Trader | Limited Company |
|---|---|---|
| Setup Cost | Low — simply register with HMRC | Low to moderate — register with Companies House |
| Tax | Income Tax and National Insurance on all profits | Corporation Tax on profits; Income Tax and dividend tax on extractions |
| Liability | Unlimited — you are personally liable | Limited — the company is a separate legal entity |
| Accounts Filing | Self Assessment tax return only | Annual accounts + CT600 Corporation Tax return + Confirmation Statement |
| Administration | Minimal — basic record keeping | Higher — statutory registers, board minutes, filings |
| Privacy | Personal information less visible publicly | Some information is public on Companies House |
| Tax Planning | Limited flexibility | Greater flexibility — salary, dividends, pension contributions |
| Growth Potential | Moderate — harder to raise finance | Excellent — easier to scale, recruit and attract investment |
Understanding how tax treatment changes with profit levels is essential for making the right decision. Here are three realistic scenarios.
Annual Profit
Recommendation
Sole Trader
An Amazon seller generating profits around £20,000 per year will often find the sole trader route the most practical. Simple bookkeeping, lower accountancy fees, minimal compliance and easy Self Assessment reporting make this the logical choice. At this level, the additional administration of a limited company may outweigh the tax benefits.
Annual Profit
Recommendation
Review Both Options
At approximately £50,000 profit, many sellers begin reviewing whether a limited company could reduce their overall tax burden. Income Tax rates, National Insurance contributions, Corporation Tax and dividend taxation all become relevant factors. This is often the point where professional tax planning becomes valuable.
Annual Profit
Recommendation
Limited Company
At £100,000 profit, a limited company structure often becomes significantly more attractive. A company director can take a modest salary, extract further profits through dividends, retain earnings for growth and improve overall tax efficiency. The tax savings typically justify the additional compliance costs.
There is no single profit threshold that triggers incorporation, but several indicators suggest it may be time to consider a limited company structure.
This is often considered the point where the tax benefits of a limited company may begin to outweigh the additional costs and administration.
A limited company is better suited to employing staff and managing payroll obligations.
If your Amazon business involves products that could create liability risk, limited liability protection becomes important.
If you plan to sell on Amazon marketplaces in Europe, North America or other regions, a limited company simplifies cross-border compliance.
While both structures can register for VAT, many sellers use VAT registration as a natural trigger point to review their overall structure.
Tick the boxes that apply to you. The more you tick, the stronger the case for a limited company.
Amazon FBA (Fulfilment by Amazon) introduces additional considerations that can influence your choice of business structure. Inventory, international sales and VAT all play a role.
FBA sellers often hold substantial inventory at Amazon fulfilment centres. A limited company structure can make stock accounting and business separation clearer. Inventory valuation, stock reconciliation and Amazon settlement report tracking all become more structured within a company framework.
Many FBA businesses eventually expand into European, North American or other global Amazon marketplaces. International selling creates additional VAT registration, currency management and cross-border tax considerations. A limited company can simplify international compliance.
Amazon settlement reports can be complex, combining sales, refunds, FBA fees and advertising costs. Many FBA sellers benefit from specialist bookkeeping and management accounts. A limited company structure lends itself to more sophisticated financial reporting.
FBA businesses can scale rapidly. When you find a winning product, inventory requirements and cashflow needs can multiply quickly. A limited company structure provides a more robust framework for rapid growth, including access to business finance and trade credit.
Both sole traders and limited companies must register for VAT when turnover exceeds £90,000 (2026/27). However, FBA sellers selling into Europe may need to consider EU VAT registration regardless of UK turnover. Our VAT specialists can guide you through these requirements.
Many FBA sellers source products from wholesalers and manufacturers. Limited companies often find it easier to open trade accounts, negotiate credit terms and build supplier relationships. A company structure can enhance your credibility in the supply chain.
This is one of the most common questions Amazon sellers ask. The honest answer is: it depends.
Lower profits often favour sole trader simplicity. Higher profits may benefit from Corporation Tax rates.
Employment income, rental income or other earnings affect your marginal tax rate and the overall comparison.
A spouse or partner as a shareholder can enable income splitting and additional tax planning.
Growth plans, sale intentions and exit strategy all influence the optimal structure.
Keeping profits in the company for reinvestment vs drawing them all out changes the tax calculation.
Liability protection may be worth more than pure tax savings for certain product categories.
Key Takeaway
A limited company is not automatically more tax efficient. Likewise, remaining a sole trader is not always the best option. The correct answer depends on your specific circumstances. Professional advice from an Amazon seller accountant can help you make the right decision for your business.
Understanding the pitfalls can save you time, money and stress. Here are the most frequent mistakes we see Amazon sellers make when choosing and managing their business structure.
Some sellers form a company before they have proven product-market fit. The additional costs and compliance burden can drain resources before the business is ready.
Others delay incorporation and miss years of potential tax savings. If your profits are growing consistently, reviewing your structure annually makes good business sense.
Using one bank account for everything creates a bookkeeping nightmare. Whether sole trader or limited company, a separate business bank account is essential from day one.
Missing invoices, receipts and Amazon settlement reports can increase your tax liability and create compliance risks. Good bookkeeping habits should start from your very first sale.
Many Amazon sellers underestimate their VAT obligations, particularly when selling into Europe. VAT registration and compliance should be monitored from the start.
A specialist Amazon seller accountant can often save significantly more than their fee through effective tax planning. DIY accounting at higher profit levels is usually a false economy.
A typical progression from side hustle to thriving Amazon business — and how the business structure evolves along the way.
Sarah starts selling homeware products through Amazon while working full-time. She registers as a sole trader with HMRC — the simplest, quickest route. She generates £12,000 profit in her first year alongside her employment income.
Sales increase significantly. Profit reaches £45,000. Sarah leaves her employment to focus on Amazon full-time. She begins reviewing whether a limited company could reduce her tax bill and starts researching her options.
Profit exceeds £90,000. Sarah incorporates her business into a limited company. She now takes a modest salary, receives dividends, retains profits for growth and benefits from limited liability protection. She works with a specialist Amazon seller accountant.
This is a common progression for successful Amazon businesses. The key is to review your structure annually and make changes when they align with your business goals — not before.
