Maryland Gov. Martin O'Malley has approved 40 new and increased taxes and fees since he took office in 2007 that are projected to cost Marylanders $9.5 billion through fiscal 2014.

"Nobody expected the total impact to be this staggering, not even me," said Larry Hogan, founder of conservative group Change Maryland, which compiled a report on the increases.

O'Malley's office says the increased revenue helped buoy a state ravaged by the recession and reeling from his predecessor.

Republican Gov. Bob Ehrlich raised taxes and fees 31 times to a tune of $3.3 billion in his four years in office. He left Maryland with a $1.7 billion budget shortfall as the recession hit.

"When our administration took office in 2007, too many of our public schools were underperforming, our state was facing a future of ever deepening structural deficits and college tuition for Maryland families had been jacked up to 40 percent," said O'Malley spokeswoman Takirra Winfield. "Gov. O'Malley has made the better choices to move our state forward."

Since taking office, O'Malley's administration has eliminated the structural deficit and lowered tax rates on 86 percent of Marylanders, Winfield said.
