Helping businesses thrive with expert accounting, tax, and advisory services.

At Landmark Accounting, we do more than balance books — we help businesses, charities and individuals 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.

We provide tailored solutions that go beyond compliance — helping our clients build stronger, more efficient businesses through proactive planning and strategic financial guidance.

With four offices across North Dublin and the Midlands, we serve clients across Ireland, from local sole traders and family-run companies to fast-growing SMEs and established corporate groups. 

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.

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.
