Easements and your property basis

What an easement is, and why it touches basis

An easement gives another party a limited right to use part of your land, for example a utility line, a pipeline, a drainage strip, a right of way or a conservation restriction. When someone pays you for that right, you have in effect sold something. Publication 551 says the amount you receive for granting an easement is generally considered to be a sale of an interest in real property. That description decides the tax treatment: a sale reduces your investment in the land rather than being ordinary income.

The rule in three steps

The publication's rule is short. First, identify the part of the property affected by the easement. Second, reduce the basis of that affected part by the amount you received. Third, if the amount received is larger than the basis of that part, reduce the basis in that part to zero and treat the excess as a recognized gain. The calculator above applies those steps.

A simple illustration, which is our own and not from the publication: a strip of land has a basis of $4,000, and a company pays you $1,500 for an easement across it. Basis in that strip drops to $2,500 and nothing is recognized. If the company instead paid $6,000, basis in the strip falls to zero and you recognize a $2,000 gain, the excess over $4,000.

Finding the basis of the affected part

The wording is about the basis of the affected part, not of the whole parcel. For a small strip that means you need to allocate part of the cost basis of the parcel to it. Publication 551 explains how to allocate a lump-sum purchase among assets by multiplying by fair market value fractions, and uses the same ratio for subdivided lots, where the numerator is the fair market value of the lot and the denominator is the fair market value of the whole tract. The easement text does not prescribe a method for the affected part, so the ratio approach is a reasonable starting point to discuss with a preparer, not a rule from the publication. If you cannot reasonably isolate the affected part, the question of how to allocate becomes a judgment that deserves professional advice.

Easement proceeds are a decrease to basis

The publication lists easements among the items that reduce basis, next to the section 179 deduction, depreciation, nontaxable corporate distributions, casualty and theft losses with insurance reimbursement, certain canceled debt excluded from income, and rebates treated as adjustments to the sales price. The list is a reminder to keep a running record. Each adjustment changes the adjusted basis you use later for gain or loss on a sale, or for depreciation, depletion or amortization.

Conservation easements at death

Easements also appear in the inherited-property rules. The publication says one possible basis for inherited property is the decedent's adjusted basis in land to the extent of the portion of the value excluded from the taxable estate as a qualified conservation easement. The details of a qualified conservation easement are in the Form 706 instructions. That rule is about inheritance and is separate from the sale rule on this page.

A worked comparison

Compare two owners of identical strips with a $4,000 basis, again as our own illustration. One receives $1,500 and ends with $2,500 of basis in the strip, which will be used later against any sale price. The other receives $6,000, has no basis left in the strip, and reports $2,000 of gain now. The first owner defers everything, but the second has already recovered the entire investment in that part of the land, and any further payment would be entirely gain.

What to keep

Keep the signed easement, the payment record, any appraisal of the affected area, a survey showing the strip, and your allocation workpaper. Those documents support the basis you reduce now and the basis you use when you sell later.

Limits of this page

This page applies the Publication 551 basis rule only. It does not tell you the character of a recognized gain (capital or ordinary, long or short term), how a state treats the payment, whether the transfer is in effect a donation, or how the gain reports on your return. Those answers depend on facts such as how long you held the land and whether it is business property. A tax professional can confirm them.
