The Committee to Save New York, the consortium of business interests and allies of Gov. Andrew Cuomo, spent $4.8 million in March and April lobbying the Legislature on the state budget and the 2 percent cap on property taxes.

The group, which registered for lobbying activity with the state after good-government organizations issued concerns, was formed to back Cuomo’s fiscal agenda at the beginning of the year.

The committee filed its financial statement with the Commission on Public Integrity today, showing the bulk of its money — about $4.1 million — was spent on TV, radio and Internet advertising.

The lobbying and PR shop DKC reported $10,000 worth of work on behalf of the group.

The committee’s filing covers March and April; the budget passed two days shy of the April 1 deadline, the start of the 2011-12 fiscal year.

The committee, which includes business groups, conservative labor unions and lobbyists with ties to Cuomo, reported spending nearly $2.6 million in January and February.

Cuomo’s proposed budget aimed at cutting spending for the first time in 15 years. The governor’s first budget also had to close a $10 billion deficit, which he pledged to do without new borrowing or new taxes.

The committee, whose board at one point included the now-head of the Empire State Development Corp. Kenneth Adams, was with the governor the entire time on the budget, running ads touting his proposal as a means to restore New York’s fiscal health.

And in the end, Cuomo got the budget he wanted passed the Legislature: no broad-based tax increases and deep cuts to the state’s most expensive items, education and health care.

With the budget passing early, it’s likely that most of its money was used to saturate the airwaves in March.

Bill Mahoney of the New York Public Interest Research Group noted that the American Beverage Association spent much more — $8.5 million — over the same period of time in 2010, when the ultimately failed wine in grocery stores issue was being heavily pushed.

Still, the $4.8 million spent is still an unusually large amount of money, he said.

“They’re haven’t been many people who spent at this level historically,” he said.

And Save New York’s work isn’t done yet. Radio ads and television commercials continue to push Cuomo’s 2 percent cap on property taxes.
