Consider the example of a taxpayer who has an adjusted gross income of $100,000 and gives a $90,000 conservation easement and $10,000 of other charitable gifts. The amendment permits $40,000 ($50,000 minus $10,000) of the value of the conservation easement to be deducted in the tax year of the gift. The $50,000 balance of the conservation easement may be carried forward and deducted over a maximum of 15 years.

The amendment, however, allows farmers or ranchers to deduct 100 percent of their contribution base in a given year if they derive at least 50 percent of their income from the trade or business of farming (I.R.C. Section 2032A(e)(5).

In the above example, if the taxpayer donating the conservation easement were a farmer, he or she could deduct the entire $90,000 in the tax year of the conservation easement donation, as well as the $10,000 of other charitable gifts. If there were a higher value conservation easement, the carryover period is 15 years.

Corporations in farming and ranching that donate a conservation easement also may qualify for the 100 percent limit.

While the 2006 amendment was extended through 2011, Harrison said the extension might not continue because of ongoing government budget discussions. Even if that's the case, tax benefits still will be available under the standard rule for those gifting a conservation easement.

While gifting a conservation easement comes with tax benefits, Harrison also said there are some initial costs.

"The process of determining the value of the development rights on a parcel of land requires a professional appraisal to determine the fair market value less the agricultural value. The difference is the conservation easement," Harrison said.

There are costs for an appraisal and for a fee paid to the entity that takes the easement and promises to monitor the easement.

"These costs should be easily offset by the income tax savings from the deduction of the easement," he said.

Harrison said landowners interested in pursuing a conservation easement should consult with an accountant or tax lawyer to learn more about how the agreement will affect personal and federal tax liability and how the transfer of the development rights will reduce potential gift, estate and inheritance taxes.
