A Decision Support System (DSS) is an interactive computer system intended to help decision makers solve problems and make decisions using data, documents, knowledge, and models. A DSS for tax administration can help analyze tax data to identify non-compliance, forecast revenues, and evaluate policies and programs. It integrates data from various tax applications into a data warehouse that supports online analytical processing, data mining, and reporting to assist with decisions.
