How to Start a Business in Ireland (2025 Guide for Entrepreneurs)

Ireland has built a reputation as one of the most dynamic business environments in Europe. Its attractive corporate tax rates, strong international connections, and English-speaking workforce make it a magnet for entrepreneurs. Whether you’re a local resident ready to strike out on your own or an international founder seeking access to the EU market, Ireland offers a clear framework to get your business started.

But while the system is welcoming, you need to understand the steps involved in registering your business, choosing the right structure, meeting tax obligations, and ensuring legal compliance. This guide expands on each stage of the journey, giving you practical insights to launch successfully.

.Step 1: How to Start a Business Choosing the Right Business Structure

The first and most important decision is selecting your legal structure, because it will shape how your business is taxed, how much liability you carry, and what administrative duties you face.

Sole Trader

A sole trader is the easiest and fastest way to begin trading. Registration is simple — you only need to register with the Revenue Commissioners for tax purposes. If you don’t trade under your own name, you also register a business name with the Companies Registration Office (CRO).

This structure suits freelancers, contractors, and small service providers. You maintain full control and keep all profits. However, you also assume unlimited liability. If the business gets into debt, your personal assets could be at risk. In addition, profits are taxed at personal income tax rates, which may become less efficient as your earnings grow.

Partnership

A partnership is similar to a sole trader, but with two or more owners. Each partner shares profits, responsibilities, and liabilities. While partnerships can be an efficient way to combine skills and resources, they require a strong partnership agreement to avoid disputes over roles, money, or exit strategies.

Limited Company

For many entrepreneurs, forming a limited company offers the best balance of protection and opportunity. A company is a separate legal entity, which means your liability is limited to the value of your shares. You can raise investment, create a professional image, and benefit from the 12.5% corporation tax rate on trading profits.

The trade-off is higher compliance: filing annual returns, keeping accounts, and maintaining records with the CRO. Limited companies involve more setup costs and require ongoing professional support, but for businesses aiming to grow, they are often the preferred choice.

Step 2: Registering as a Sole Trader or Partnership

If you decide on the sole trader or partnership route, the process is straightforward. You begin by registering for tax with the Revenue Commissioners using your PPS (Personal Public Service) number. This ensures your income is properly recorded for taxation.

If you want to use a business name that isn’t your own, you must file a registration with the CRO. For example, if John Murphy runs “Murphy Digital Design,” he must register that name with CRO even though he is a sole trader.

The application is quick and inexpensive (about €20 online), and once approved, you can use your business name on invoices, signage, and marketing materials. From there, you’ll need to keep basic financial records and file an annual income tax return.

Partnerships follow the same process but require all partners to register, and it’s highly recommended to draft a written partnership agreement. This should outline responsibilities, profit-sharing, dispute resolution, and what happens if a partner leaves the business.

Step 3: Setting Up a Limited Company

Forming a limited company requires a more structured approach. First, you choose your company name and check availability with the CRO. Next, you prepare incorporation documents that include details of:

• Directors: At least one must be an EEA resident, unless you arrange a bond.

• Shareholders: They own the company through shares.

• Company Secretary: Responsible for compliance.

• Registered Office: Must be an address in Ireland.

  
  

After submitting your documents and paying the CRO fee (about €50 online), you’ll receive a Certificate of Incorporation. This confirms that your company legally exists.

Once incorporated, you must register with Revenue for corporation tax and, depending on turnover, for VAT. Limited companies also face ongoing compliance: filing annual returns, maintaining statutory registers, and producing financial statements. While these obligations may seem heavy, many entrepreneurs hire accountants or company formation agents to handle the process smoothly.

Step 4: Tax Registration and Compliance

Understanding your tax obligations is critical for avoiding fines and building a sustainable business.

• Sole Traders pay Income Tax on profits, at 20% for the standard rate and 40% for higher earnings. They must also contribute PRSI (Pay Related Social Insurance) and USC (Universal Social Charge).

• Limited Companies pay Corporation Tax at 12.5% on trading profits. If profits are retained within the company, this can be more tax-efficient. Directors then pay personal tax on salaries or dividends they take.

• VAT registration is mandatory if turnover exceeds thresholds: €40,000 for goods or €75,000 for services. Even if below the threshold, some businesses choose voluntary VAT registration to claim back input VAT.

• Employers must register for PAYE (Pay As You Earn) when hiring staff and comply with PRSI and pension rules.

  
  

Keeping accurate records is essential, regardless of structure. Digital accounting tools are widely used in Ireland to track invoices, expenses, and compliance deadlines. Many small businesses hire accountants to ensure they meet requirements.

Step 5: Opening a Business Bank Account

A dedicated business bank account isn’t just good practice — it’s often a necessity. For sole traders, a personal account can technically be used, but separating personal and business finances makes accounting and tax filing much cleaner.

For limited companies, a separate bank account is mandatory, as the company is a distinct legal entity. To open one, you’ll usually need proof of identity, proof of address, tax registration details, and your CRO incorporation certificate.

Having a business account improves your credibility with clients, suppliers, and banks. It also makes applying for loans or grants much easier. Most Irish banks offer tailored packages for startups, often with low or no fees for the first year.

Step 6: Additional Considerations

Depending on your industry, additional steps may apply. Certain sectors — such as food service, childcare, healthcare, or financial services — require specific licenses or permits before you can operate legally. It’s crucial to research these early to avoid delays.

Insurance is another important factor. While not always legally required, policies like public liability, professional indemnity, or employer’s liability provide essential protection. Many landlords, clients, or contracts will require proof of insurance before working with you.

Finally, if you plan to employ staff, you must register as an employer with Revenue, operate PAYE, and contribute PRSI. You also have legal obligations around workplace pensions and employee rights. Ireland has strong labor protections, so compliance is essential.

For support, entrepreneurs can access government programs such as Local Enterprise Offices (LEOs), which provide grants, mentoring, and training. Agencies like Enterprise Ireland also support startups with global ambitions.
