If you upgraded one or more of the following systems last year, you may be eligible to take a tax credit — up to $500 — on your return.Biomass stoves Heating, ventilation, air conditioning InsulationRoofs (metal and asphalt) Water heaters (non-solar) Windows, doors, and skylights  Advanced main air-circulating fans (the blower motor that blows heated air through your ducts)The energy tax credits are small, but at least a credit is better than a deduction:Deductions just reduce your taxable income.With a credit, you get a dollar-for-dollar reduction in your tax liability: If you get the $500 credit, you pay $500 less in taxes.Limits on IRS Energy Tax Credits Besides $500 MaxCredit extends to 10% of the cost, so you have to spend $5,000 to get $500.$500 is a lifetime limit. If you pocketed $500 or more in past years combined, you’re not entitled to any more money for energy-efficient improvements in the above categories. But if you took $300 in years past, for example, you can get up to $200 now.

With some systems, like windows, your cap is even lower than $500.$500 is the max for all qualified improvements combined.Certain Systems Capped Below $500No matter how much you spend on some approved items, you’ll never get the $500 credit — though you could combine some of these:SystemCapNew windows$200 max (and no, not per window—overall)Advanced main air-circulating fan$50 maxQualified natural gas, propane, or oil furnace or hot water boiler$150 maxApproved electric and geothermal heat pumps; and natural gas, propane, or oil water heaters$300 maxAnd not all products are created equal in the feds’ eyes. Improvements have to meet IRS energy-efficiency standards to qualify for the tax credit. In the case of boilers and furnaces, they have to meet the 95 AFUE standard. Windows, skylights, and doors meet Energy Star 6.0 standards.Tax Credits Cover Installation — SometimesRule of thumb: If installation is either particularly difficult or critical to safe functioning, the credit will cover labor.
