Revenue authorities are responsible for the administration of tax as well as non-tax revenues. They also act as tax policy advisors and research analysts on governments' taxation and fiscal policies. Their data is often split across systems, which makes it difficult to offer integrated views of tax filing, payments, and assessment and service history. Techno Brain's Enterprise Data Warehouse System helps revenue authorities manage the impact of policy changes, generate revenue, reduce fraud, and reduce non-compliance. Our solution facilitates centralised collation of information for better decision making.
