GREENFIELD — This year, because of the federal holiday, the deadline to file income tax returns was moved from its usual date of April 15 to April 18, and Greenfield Republicans are using the extra time to party and talk taxes.

They will hold a fundraising event this evening from 6 to 8 p.m. at Taylor’s Tavern, featuring a talk by state Senate Minority Leader Bruce Tarr, R-Gloucester, about the state of taxes in Massachusetts.

Sen. Tarr has been an advocate on many proposed tax reductions, including the push to lower the income tax to 5 percent, the increase to the earned income tax credit and recently-rebuffed efforts to eliminate the film tax credit. Tarr leads the five Senate Republicans and is ranking minority member the Committee on Post Audit and Oversight. Most recently, he sponsored legislation to create a Finance Control Board for the MBTA.

The event is hosted by George Gohl, who was just reinstalled as Greenfield Republican Town Committee chairman.

Gohl leads 30 members who were elected on the March presidential primary ballot as well as one write-in — Dan Oros — who received enough votes to get on the committee.

“Republicans are motivated in Greenfield, especially as we have been talking about taxes on the local level,” Gohl said in a news release. “The new Town Council is really making an impact.”

Earlier this year, Tarr endorsed for president Ohio Gov. John Kasich. Greenfield Town Councilor Isaac Mass, also a Kasich supporter, will speak during the fundraiser about his efforts to become a delegate to the Republican National Convention this July in Cleveland.

Mass plans to go to the convention uncommitted after the first ballot.

“I want a nominee who will unite our party, who can win, and who will do a good job in the office,” Mass said in the release.

Massachusetts Republicans choose delegates April 30 at 10 a.m. in Shrewsbury. Mass, who was an alternate in 2000 and delegate in 2008, is running a bus to the 2nd congressional district caucus.
