Advertising in Ireland is not a regulated profession. Service providers wishing to set up advertising agencies can do so. However, there may be rules to be followed in setting up a company and there may also be some tax requirements. Further details of these rules and requirements can be found in the links menu on the left.

Many advertising agencies belong to the Institute of Advertising Practitioners in Ireland (IAPI). IAPI's role is to promote the highest professional and creative standards in the production of advertising, across all media. IAPI plays a key role in the Irish advertising industry, which is reflected in its range of activities.
