Deacy Gilligan Ltd
We are proud to provide high-quality accountancy and tax planning services tailored to the needs of a diverse range of clients.
At Deacy Gilligan Ltd, we do more than balance books — we help businesses grow, adapt, and thrive. With decades of combined experience in taxation, accounting, and business strategy, our mission is to give clients the clarity, control, and confidence they need to succeed.
Based in Galway Financial Services Centre, we serve clients across Ireland, from local sole traders and family-run companies to fast-growing SMEs and established corporate groups. We provide tailored solutions that go beyond compliance — helping our clients build stronger, more efficient businesses through proactive planning and strategic financial guidance.
We’re not just here for year-end accounts and tax returns. We’re here to support your journey — whether that means reducing your tax liabilities, navigating a business restructure, preparing for succession, or launching something entirely new.
Who We Work With
Our clients range from ambitious start-ups and family businesses to established SMEs and growing companies in Galway and across the region.
Private individuals needing personal tax advice: Whether you're managing your income, preparing for retirement, or navigating complex tax matters like capital gains or inheritance tax, we offer clear, actionable advice to help individuals plan, optimise, and safeguard their financial future.
Start-ups looking to get established with strong financial foundations: We work closely with entrepreneurs to set up their businesses on a solid financial footing. From structuring the business and managing cash flow to understanding tax obligations, we help you make strategic decisions for long-term success.
SMEs seeking cost-effective outsourced finance departments: Many growing businesses don’t have the need or resources for a full-time finance team. We offer outsourced finance services to manage everything from bookkeeping and payroll to management accounts, ensuring your business runs efficiently and stays compliant while saving you time and money.
Family businesses planning succession or retirement: Family-run businesses face unique challenges when it comes to succession planning and preparing for the future. We help you navigate the complexities of passing on leadership, managing tax implications, and ensuring a smooth transition to the next generation.
Growing firms exploring funding, expansion, or international trade: As your business expands, you need a partner who can help you access new opportunities. Whether you’re seeking investment, expanding your market, or exploring global trade, we provide the guidance and resources to make your growth plans a reality.
Corporates requiring audit, compliance, or advanced advisory services: For larger organisations, we offer sophisticated solutions to ensure compliance, streamline operations, and provide strategic direction. From audits and regulatory compliance to high-level financial advisory, we support corporate clients in achieving sustainable, long-term success.

How We Help You Grow
We believe that great advice pays for itself — and then some. Here’s how we help you make better business decisions:
Proactive tax planning that keeps more of your profits where they belong — in your business: We go beyond simple tax filing by helping you optimise your tax position throughout the year. By identifying potential tax savings, claiming all eligible deductions, and leveraging tax reliefs, we ensure you keep more of your hard-earned profits to reinvest in your business and achieve long-term growth.
Clear financial reporting to give you visibility over cash flow, profitability, and growth: We provide regular, detailed financial reports that give you a clear picture of your company’s financial health. Whether it’s cash flow analysis, profit margins, or tracking expenses, our reports help you make informed decisions, monitor progress, and identify areas for improvement.
Regular strategic check-ins to align your business performance with your long-term goals: We don’t just provide reports and advice — we partner with you for regular reviews to ensure your business is on track to meet its goals. By evaluating your financial position, performance metrics, and strategic initiatives, we help you adjust your approach to stay aligned with your long-term vision.
Smart structuring and compliance to help you avoid penalties and prepare for the future: Proper business structure and tax compliance are essential for long-term success. We advise on the best legal and financial structures for your business, helping you stay compliant with regulations while reducing the risk of penalties, audits, or costly mistakes.
