Running a business as a sole trader works well in the early stages. It is simple to set up, flexible to operate, and gives you full control. But as your business grows, the benefits start to shift. You may be paying more tax than you need to, carrying personal risk you do not want, or struggling to build business credit. That is when many business owners consider switching to a limited company. It is not just a legal change—it is a strategic move that affects how you pay tax, raise money, sign contracts, and present your business to the outside world. In this blog, we explain when to make the switch, what the process involves, and how AFG helps sole traders transition with minimal disruption and maximum clarity.
There are several common reasons why sole traders decide to incorporate. These include:
Reducing personal liability by separating business and personal finances
Taking advantage of Corporation Tax rates rather than personal income tax
Accessing better funding or investment opportunities
Building a more credible business profile with clients and suppliers
Preparing for future growth, recruitment, or exit plans
The decision is not about ticking a box. It is about aligning your business structure with your goals. If your revenue is increasing, your profits are stable, or you are starting to think long term, operating as a limited company may offer better protection, tax efficiency, and opportunity.
The most important change is legal structure. A limited company is a separate legal entity. That means it can own assets, enter contracts, and be held accountable in its own right. As a director, you are responsible for running the company, but you are not personally liable for its debts unless you breach your duties or provide personal guarantees. Other key differences include:
You will pay Corporation Tax instead of income tax
You must register with Companies House and submit annual accounts
You must operate PAYE if you pay yourself a salary
You may be eligible for dividends, which are taxed differently from self-employment income
Your financial records are more visible, and you must follow company law
These changes come with added responsibility, but also added opportunity. With the right systems in place, most business owners find the benefits outweigh the extra admin.
There is no universal answer, but there are some clear signals. You might be paying high levels of income tax and National Insurance. You might want to reinvest profits rather than draw them all as personal income. You might want to protect your personal assets or separate your business from your personal finances. You might also be bidding for contracts or working with clients who prefer to deal with limited companies. In general, if your annual profits are reaching or exceeding £30,000 to £40,000, it is worth exploring incorporation. That does not mean every business should do it immediately, but it should be part of your planning discussion.
As a sole trader, you pay income tax and Class 2 and Class 4 National Insurance on your profits. As a limited company, the company pays Corporation Tax on its profits, and you pay personal tax only on the income you draw, either through salary or dividends. This creates opportunities to reduce your overall tax bill, especially if you leave some profits in the business or take advantage of dividend allowances. You can also employ family members, claim a wider range of expenses, and plan your withdrawals more flexibly. However, it is important to run the numbers. Incorporation may bring savings, but only if the structure is used properly. AFG helps clients model different scenarios and build the right plan before making the move.
If you have been trading for some time, you likely have assets, agreements, or obligations in your sole trader name. These do not automatically transfer to the limited company. You may need to:
Open a new business bank account in the company’s name
Transfer ownership of equipment, stock, or intellectual property
Notify clients, suppliers, and insurers of the change
Update invoicing details and terms of business
End sole trader contracts and issue new ones from the company
In some cases, you may need to charge VAT on the asset transfer if you are registered, or ensure that your existing liabilities are clearly ringfenced. AFG helps clients manage this process so that nothing is missed and your transition is clean.
If you have built up brand recognition as a sole trader, you may want to keep your trading name. This is possible. You can register a limited company with the same name if it is available, or register under a different name and continue trading under your existing brand. The key is to register any name you want to protect and make sure your marketing, invoices, and legal documents reflect the correct legal structure. We help clients secure company names, set up the right trading disclosures, and update all records to reflect the new position.
If you are already VAT registered as a sole trader, you cannot transfer the registration to the new company. You must cancel the existing VAT registration and register the company separately. This also applies to PAYE and other HMRC registrations. You must treat the company as a new taxpayer. It is important to plan this carefully so that your VAT status continues uninterrupted. We assist with VAT transfer of business as a going concern where applicable and ensure that the new company is registered properly from day one.
Limited companies must submit annual accounts to Companies House and file a Corporation Tax return with HMRC. You must also submit a confirmation statement each year and maintain proper statutory records. These requirements are stricter than those for sole traders, and the deadlines are different. AFG helps clients manage all of these filings and keeps a calendar of compliance so that nothing is missed. We also provide management accounts and advisory services so that you have real-time visibility, not just year-end paperwork.
You will need to open a new business bank account in the company’s name. This account should be used exclusively for company transactions. Mixing personal and business money can create compliance issues and undermine the limited liability protection. You should also review your insurance policies to ensure they cover the limited company. Some sole trader policies do not automatically transfer. We help clients update their banking and insurance arrangements to reflect the new structure.
