6 Ways to Get a Bigger Tax Refund

If you made environmental improvements -- energy-efficient windows, doors, insulation, heating and air conditioning systems -- the government wants to offset the cost. Get a tax credit for 30 percent (up to $1,500 for most enhancements, although there's no upper limit for solar panels or solar water heaters). And while a new Energy Star fridge doesn't qualify for 2009, if you buy an energy-efficient appliance in 2010, your state may offer a rebate. Details vary by state, so ask your state's energy office for more info.
