AARC supported the Montenegro Tax Administration (MTA) through the delivery of a technical support program focused on the improvement and modernization of business processes in advance of the deployment of a new Integrated Revenue Management System (IRMS). AARC Ltd provided tools and methods to define the “to-be state” and its associated processes and business specifications in the areas of Internal control and integrity function, Tax return and payment processing, Tax audit and Taxpayer services. We have incorporated all the important aspects such as: alignment to EU taxation norms, compliance with the EU and other best practices, compliance with local legal regulations, as well as modern concepts in the functioning of modern tax administrations in the To-Be Processes leading to better Tax compliance.
