Going “green” has become all the rage lately, with more people embracing energy-saving tactics at home and at work. But Mother Earth isn’t the only one who stands to benefit from the emphasis on eco-friendliness—did you know that you can earn significant tax credits for energy-efficient improvements?

Earlier this year, the American Recovery and Reinvestment Act (ARRA) outlined some new and expanded tax benefits for individuals and business owners who invest in energy-saving appliances, improvements, or alternate energy sources that result in reduced usage and conserved resources.

Homeowners can earn a tax credit of up to 10% of the cost of solar energy systems, energy-efficient construction, or other alternate energy sources. This isn’t just a deduction of your income—it’s a full credit that is deducted directly from the amount of taxes you’re required to pay.

Each individual improvement is subject to its own set of criteria. Below are some specific green tax incentives available to business owners:

• Commercial buildings: If you build or renovate a commercial building that uses 50% or more less energy than the national average, you may be entitled to a tax credit of up to $1.80 per square foot.
• Combined heat and power systems (CHPs): If you institute a CHP that meets the minimum efficiency specifications, you could be eligible for an investment tax credit of up to 10%.
• Commercial vehicles: If your business uses fuel-efficient hybrid vehicles, you can earn tax credits based on the weight, fuel economy, and purchase price of the vehicle.
• Fuel cells and microturbines: If you invested in these eco-friendly technologies this year to generate electricity and power for your business, you could be eligible for tax credits of 30% of the cost of fuel cells or 10% of the cost of microturbines.
• Solar energy systems: Businesses that use solar energy for lighting, water heating, or electricity can receive up to 30% of the cost of the system in the form of a tax credit.

It’s great that the IRS is taking steps to recognize and reward energy-saving measures, but the specific clauses are complex. Eligibility is dependent on where you live, whether your investment meets specific criteria, and when the energy-saving tactic was put into place. There are extensive provisions, changes, and limitations that can be confusing for the average taxpayer to decipher. To make sure you’re reaping the maximum benefit of the new “green” tax laws, it’s best to consult with your CPA.

As we approach the end of another calendar year, it can be tempting to clear out all those backlogged tax files and start fresh for 2010. But don’t start feeding all those old records to the shredder just yet—first, consider the following.

As a general rule, CPAs recommend hanging onto the past three years’ worth of tax records. That’s equivalent to the federal government’s statute of limitations for questioning or auditing your tax information. There are a few exceptions—some states have up to four years to examine your return, and the statute can be extended or removed in cases of fraud, significant income omission, or tax evasion. But taxpayers who have filed in a timely manner and paid any outstanding taxes by the due date can confidently purge any records three years after the date the return was filed.

It’s important to note that the three-year rule only applies to supporting documents and information related to your tax return. Other records, specifically those that detail capital assets, should be kept until the end of the statute period following their liquidation. Below are some examples:

• Tax returns: Although supporting documentation can usually be purged after the three-year mark, it’s wise to keep the actual returns themselves. These can prove invaluable in securing a loan or applying for insurance.
• Income and expenses: Hang onto any and all documents that verify your income for at least three years after you file. These include W-2s, 1099s, bank statements, and brokerage statements. Records of business-related expenses should also be kept.
• IRA contributions: Retain records of non-deductible contributions until the money is withdrawn, to avoid getting taxed twice on those funds.
• Stock information: Keep all records of stock ownership for at least four years after the sale of your shares. In the event of an audit, you’ll need these to verify any profit or loss resulting from the sale.
• Stock and mutual fund statements: Any stock dividends that are reinvested will reduce the amount of capital gain, thus lowering your taxable income. These statements should also be kept for at least four years after the sale, to provide a record of reinvested dividends.
• Home purchase and renovation receipts: If you’ve purchased a home or made significant improvements to a property you own, hang onto these records for at least four years after the sale of the property.

When in doubt as to whether to get rid of tax records, it’s best to give your CPA a call. He or she can help you determine the importance of the document and whether you’ll need to reference it down the road.
