Lagos State Inland revenue Service (LIRS) is the major revenue generating Agency of the Lagos State Government saddled with the responsibility of collecting taxes. Over the years, LIRS has increased the State’s Internally Generated Revenue (IGR) by executing various pioneering programs and implementing strategies which have impacted positively on revenue generation and collection, with the IGR moving from a monthly average of about 600 Million Naira in 1999 to approximately 20.5 Billion Naira in 2013, thereby making Lagos State less dependent on proceeds from the Federation Account.
