<h1>Demonetisation Boosted Tax Revenue and Expanded Tax Base, Says Government; Significant Rise in New Tax Filers Noted.</h1> Demonetisation led to the detection of black money, increased tax collection, and a broader tax base, as stated by a government official in a parliamentary session. Between November 2016 and March 2017, tax authorities conducted numerous searches, seizing significant amounts of cash and uncovering undisclosed income. The financial year 2017-18 saw an 18% growth in net direct tax collections, with substantial increases in personal income tax and self-assessment tax collections. The number of new tax filers also rose significantly. Investigations under money laundering and foreign exchange laws revealed unaccounted money, resulting in asset seizures and penalties.
