MICROPAS 45L Tax Credit Software
Raters use CHEERS 45L tax credit services to verify a project or a set of plans meets the stringent energy efficiency requirements of the $2,000 Section 45L tax credit. CHEERS 45L is the exclusive user of MICROPAS v7.60 45L software.
MICROPAS 45L software is developed by Enercomp, Inc. and has been used by national builders throughout the country since the inception of the 45L Tax Credit in 2006.
MICROPAS v7.60 is an update to the IRS approved versions v7.3 and v7.4.
