Business Structures


One of the most important decisions you will make when starting or growing a business is how to structure it. The structure you choose affects everything from the amount of tax you pay to your personal liability, your ability to raise finance, the administrative burden you take on, and how easy it is to bring in other owners or exit in the future.

In Ireland, the most common business structures are sole tradership, partnership, limited liability company, and designated activity company. Each has its own advantages and disadvantages, and the right choice depends on the nature of your business, your personal circumstances, your growth plans, and your attitude to risk.

At Book Smart Accountancy, we advise clients at every stage of their business journey on the most appropriate structure for their needs. Whether you are just starting out and trying to decide whether to operate as a sole trader or set up a company, or you are an established business considering restructuring to improve efficiency or prepare for a sale or succession, we provide clear and practical advice tailored to your specific situation.


We also help with the practical steps involved in establishing or changing your business structure, including company formation, registration with Revenue, preparation of shareholders agreements, and restructuring of existing businesses where required.

Getting your structure right from the outset, or at the right time as your business evolves, can save significant money in tax, reduce personal risk, and make your business more attractive to investors, lenders, and future buyers.

Things to Know or Watch Out For with Business Structures

  • A Sole Trader Has Unlimited Personal Liability - Operating as a sole trader means that there is no legal separation between you and your business. If the business incurs debts or faces legal claims, your personal assets, including your home, are at risk.
  • A Limited Company Provides Liability Protection but Has Higher Compliance Costs - Incorporating as a limited company protects your personal assets in most circumstances, but it comes with ongoing obligations, including annual returns, financial statements, company secretarial duties, and potentially higher accounting fees.
  • The Tax Treatment Differs Significantly Between Structures - Sole traders and partners pay income tax at rates of up to 40%, plus PRSI and USC. Companies pay corporation tax at 12.5% on trading profits. However, extracting profits from a company as salary or dividends triggers personal tax, so the overall benefit depends on how much you need to draw out of the business.
  • Changing Structure Later Can Have Tax Consequences - Transferring a business from a sole trader to a company, or restructuring from one company structure to another, can trigger capital gains tax or stamp duty if not planned carefully. There are reliefs available that can defer or eliminate these charges, but they must be structured correctly.
  • A Shareholders Agreement Is Important in Multi-Owner Companies - Where a company has more than one shareholder, a properly drafted shareholders agreement is essential. Without it, disputes between shareholders can be costly and difficult to resolve.
  • Partnerships Offer Flexibility but No Limited Liability - A traditional partnership provides flexibility in profit-sharing and management, but like a sole trader, each partner has unlimited personal liability. A Limited Liability Partnership (LLP) is available to certain professionals and provides some protection.
  • Revenue Registration Requirements Vary by Structure - Different structures have different registration requirements with Revenue. A sole trader must register for income tax; a company must register for corporation tax; both may need VAT registration separately. We ensure all registrations are completed correctly from the outset.
  • Your Business Structure Affects Your Ability to Raise Finance - Banks and investors often have preferences about how a business is structured. A limited company with audited accounts and a separate legal identity is typically easier to finance than an unincorporated business.

Frequently Asked Questions

The right answer depends on your circumstances. Key factors include the level of profit you generate, your personal tax position, your risk appetite, your plans for growth, and whether you intend to bring in other shareholders. We work through these factors with you and provide a clear recommendation based on your specific situation.
A limited company carries higher ongoing compliance costs, including accounting fees, audit costs where applicable, CRO filing fees, and company secretarial costs. However, for many businesses the tax savings and liability protection more than outweigh these costs. We can prepare a simple comparison for you based on your figures.
Yes. Many business owners start as sole traders and incorporate as the business grows. The process involves registering a new company, transferring the business and its assets to the company, and updating all registrations with Revenue, suppliers, and customers. There are reliefs available that can allow the transfer to be made without triggering immediate tax charges, but the transaction needs to be structured carefully. We manage this process for clients regularly.
Both are Irish company types registered under the Companies Act 2014 and both provide limited liability protection. A limited company (LTD) is the most common type and is suitable for most commercial businesses. A designated activity company (DAC) is used where the company's activities need to be specified and restricted in its constitution, for example in certain financial services or joint venture contexts. For most small and medium businesses, a standard LTD is the appropriate choice.
If your company has more than one shareholder, a shareholders agreement is strongly recommended. It sets out the rights and obligations of each shareholder, how decisions are made, what happens if a shareholder wants to leave or sell their shares, and how disputes are resolved. Without one, you are relying on the default provisions of company law and the company's constitution, which may not reflect what the shareholders actually agreed or intended.
A holding company is a company that owns shares in one or more subsidiary companies rather than trading directly. Holding structures are commonly used for asset protection, to facilitate the accumulation of retained profits at a lower tax rate, to plan for succession or sale, or to hold investments separately from trading activities. Whether a holding company is appropriate depends on the size and complexity of your business and your longer-term plans. We can assess whether this structure would benefit you.
There are several ways to extract profits from a company, including salary, pension contributions, dividends, and director's loans. Each has different tax implications for both the company and the individual. The most tax-efficient approach depends on your personal tax position, the level of profits in the company, and whether you need the income now or are willing to defer it. We develop a tailored extraction strategy for each client to minimise the overall tax cost.
Yes. We handle the full company formation process, including incorporation with the CRO, registration with Revenue for corporation tax and any other applicable taxes, appointment of directors and company secretary, preparation of the company constitution, and opening of a bank account if required. We make the process as straightforward as possible so you can focus on getting your business up and running.
