THE FEDERAL TAX CREDIT WAS REINSTATED, $150 tax credit for a natural gas, propane, or oil boiler with an AFUE of not less than 95%: January 2nd - President Obama signed legislation designed to avoid the “fiscal cliff” and keep tax rates from increasing for every American who pays taxes. In addition to its many other tax provisions, the bill retroactively reinstates the 25C tax credits for highly efficient HVAC equipment that expired at the end of 2011. Specifically, the bill extends the tax credits that expired in 2011 from January 1, 2012, until December 31, 2013, for qualified equipment listed in Section 25C of the Internal Revenue Code. Because the credits were made retroactive to January 1, 2012, they can be used for qualified equipment that was installed any time after December 31, 2011.
