Taxpayers in the Rural Municipality of Corman Park, which encircles Saskatoon, are expressing shock over tax increases of 37 and 17 per cent.

The 37 per cent increase is in place for 2012 taxes. It follows a previous hike of 17 per cent.

One resident, Garry Derenoski, told CBC News that the most recent increase will add another $1,300 to his tax bill.

"Ratepayers are absolutely going berserk over this," Derenoski said. "They're alarmed, they're angry and I believe there's enough momentum on this that this RM will see a tax revolt."

He said he is hoping others in the RM will contact council members.

About 8,400 people live in the RM.

"I think it's bizarre," Derenoski added. "You wonder what the RM is doing with all the money. You can only equate that, from my personal perspective, to mismanagement."

Mel Henry, the reeve, said the RM should have been raising taxes in previous years but did not.

"It should've been done over the past 15 years," Henry said. "It should've been small increments."

Henry added that planning was not done to address maintaining roads and other infrastructure, which is contributing to the need for a large tax hike.

Henry said previous RM leaders are responsible for the current situation.

"We're not going to hide it, as had been done in the past, or smooth it over like it's been done in the past," he said. "We're going to meet it head on because if we don't, the RM is going to be in real deep financial trouble down the road."

Henry noted that a $2 million expense, required to decommission the RM's landfill, is one of the reasons for this year's hike.
