In several of the last states to open casinos, revenue has been coming in below levels projected during the planning stages. Here is a look at how estimates compare with actual revenue in Ohio, Maryland and Pennsylvania:
In October 2009, the Ohio Department of Taxation estimated that the state could generate $470 million to $643 million in annual tax revenue once four casinos were running. At the time, Ohio was considering a constitutional amendment to allow the casinos. In 2014, the total tax collected from casino revenue was $267.5 million.
The Department of Legislative Services gave an estimate in December 2008 that five newly approved slot machine parlors could generate $1.36 billion in total revenue in fiscal year 2013, a conservative number compared to consultants' figures. Voters in 2012 approved legalization of table games at Maryland casinos. In fiscal year 2014, Maryland's four operating casinos generated $833 million in revenue.
State task force estimates for a dozen casinos in Pennsylvania projected total revenue of $2.54 billion from slot machines. Slot revenue from those casinos totaled $2.32 billion in 2014. Including revenue from table games, which Pennsylvania legalized in 2010, total revenue reached $3.07 billion.
