We are a member of The International Accounting Group, or TIAG® - a worldwide alliance of international accounting firms. The alliance comprises more than 115 independent accounting firms located in 200 offices that span over 70 countries and give our firm global reach. Together with its sister alliance of 160+ independent law firms in over 90 countries, TAGLaw®, the TAG AlliancesTM rank as one of the top three independent accounting and legal alliances in the world.


Our clients have benefited from tax, legal and other expertise sourced from accountants and other experts in foreign countries. With the increased awareness and willingness of Northern Ireland businesses to explore external markets, we consider TIAG® an excellent resource for the needs of GMcG and our clients.

Given that one of our leading areas of expertise is forensic accounting and the provision of litigation support services to the legal profession we have already seen client and firm benefits derived from both the TIAG® and TAGLaw® alliances.

Unlike other options in the marketplace, TIAG®provides its diverse international members with superior opportunities for collaboration and resources to assist clients with their strategic planning. The TAG Alliances (TIAG®, TAGLaw® and TAG-SP®) have been ranked in the top three Accounting Associations globally for the past nine consecutive years, by Accountancy Age magazine.
