People can now weatherize their homes and be rewarded for their efforts. According to the Internal Revenue Service, homeowners making energy-saving improvements this fall can cut their winter heating bills and lower their 2010 tax bill as well.

Homeowners going green should also check out a second tax credit designed to spur investment in alternative energy equipment. The residential energy efficient property credit equals 30 percent of what a homeowner spends on qualifying property such as solar electric systems, solar hot water heaters, geothermal heat pumps, wind turbines, and fuel cell property. Generally, labor costs are included when figuring this credit. Also, except for fuel cell property, no cap exists on the amount of credit available.

Not all energy-efficient improvements qualify for these tax credits. For that reason, homeowners should check the manufacturer’s tax credit certification statement before purchasing or installing any of these improvements. The certification statement can usually be found on the manufacturer’s website or with the product packaging. Normally, a homeowner can rely on this certification.

The IRS cautions that the manufacturer’s certification is different from the Department of Energy’s Energy Star label, and not all Energy Star labeled products qualify for the tax credits.

Eligible homeowners can claim both of these credits when they file their 2010 federal income tax return. Because these are credits, not deductions, they increase a taxpayer’s refund or reduce the tax owed. An eligible taxpayer can claim these credits, regardless of whether he or she itemizes deductions on Schedule A. Use Form 5695, Residential Energy Credits, to figure and claim these credits.
