ITSS (Irish Taxation Software Services) are a dynamic team of Chartered Tax Consultants and Software Developers who have been developing Ireland’s market leading tax software for many years. ITSS is a 100% Irish owned company. As a Business Partner of Sage we design, develop and support the Sage Personal and Corporation Tax Compliance Software from our Cork office. The team has a combined experience in taxation software development of over 25 years with a background in Tax Practice (KPMG and Smith & Williamson). In addition to the development of software we provide a unique tax compliance support and advice service to all our customers. Our software is only a fraction of the service, the remainder is the unlimited access our clients have to Chartered Tax Consultants with specialist knowledge of Tax compliance in addition to an in-depth knowledge of the ROS system. We focus on accuracy; the software provides tax computations independent of ROS, in addition to being a management tool that is fully integrated with the ROS system for online filing. Our detailed knowledge of the Accountants Market has allowed us to understand our clients’ needs and address these needs through rapidly evolving the software. The Sage Tax products are used in hundreds of Accountancy Firms daily across the country including all of the Big 4 Accountancy Firms. The Sage Tax products handle the largest amount of Tax Returns Filed annually to the Revenue by any third party Tax software.
