Can You 1031 Exchange Part of Your Land?

Yes, in most cases. You can sell part of a parcel you hold for investment, such as a few acres of a larger tract or an outparcel at a shopping center, and exchange the proceeds into replacement property under Section 1031. The portion you keep stays outside the exchange. The parts that need care are splitting your tax basis between the sold and retained land, handling any loan that covers the whole property, and making sure the sale does not look like a developer selling lots.

Does the whole property have to be sold?

No. Section 1031 applies to the property you actually transfer. If you own 40 acres and sell 10, the 10 acres are the relinquished property and the other 30 simply remain yours, with nothing changed for tax purposes.

The same idea applies to commercial property. Owners of retail centers often sell a pad site or outparcel to a restaurant or bank while keeping the main building. Farm owners sell road frontage. Owners of a duplex on a double lot sometimes split off and sell the vacant lot. Each of these can generally be the relinquished side of an exchange, provided the land was held for investment or for use in a business.

How do you work out the basis of the part you sell?

This is the step owners most often skip. Your gain on the sale is the price you receive minus the tax basis of the portion sold, not the basis of the whole property. So the original basis has to be allocated between the piece you are selling and the piece you are keeping.

The usual approach is to allocate by relative fair market value at the time you acquired the property, not simply by acreage. Road frontage, a corner lot or a pad site is often worth far more per acre than back land. An appraisal or other reasonable valuation from around the purchase date supports the split, and your CPA decides the method.

What does that look like with numbers?

Illustrative example only. These figures are invented to show the arithmetic, ignore closing costs, and do not describe any real property or outcome.

Suppose an owner bought 40 acres for 400,000 dollars. At the time, the 10 acres along the highway were valued at 160,000 dollars and the remaining 30 acres at 240,000 dollars. Years later the owner sells the 10 highway acres for 500,000 dollars.

• ›Basis allocated to the 10 acres sold: 160,000 dollars, which is 40 percent of the original price
• ›Gain on the sale: 500,000 less 160,000, which is 340,000 dollars
• ›Basis kept with the 30 acres retained: 240,000 dollars

If the owner had split the basis by acreage instead, the 10 acres would carry only 100,000 dollars of basis and the gain would appear to be 400,000 dollars. The method changes the number being deferred, and it also changes the basis left in the land you keep.

What if there is a loan on the whole parcel?

A single mortgage that covers the entire property is common. When you sell part of it, the lender will usually require a partial release payment at closing, a set amount paid down on the loan in exchange for releasing the sold portion from the mortgage.

That paydown matters for the exchange. Debt paid off at closing is generally treated as debt relief on the property you sold. To defer all the gain, you typically need to offset it on the replacement side with new debt of at least the same amount or with additional cash of your own. If you do neither, the amount can be taxable as mortgage boot.

Continuing the illustration, if the lender requires a 150,000 dollar release payment from the 500,000 dollar sale, only 350,000 dollars reaches the Qualified Intermediary. To defer fully, the owner would generally buy replacement property of at least 500,000 dollars, using the 350,000 dollars of exchange funds plus at least 150,000 dollars of new financing or fresh cash.

Can subdividing the land cause a problem?

It can. A 1031 exchange applies to property held for investment or for use in a business, not property held primarily for sale. If an owner subdivides a tract, puts in roads and utilities, markets the lots and sells them one after another, the tax code may treat that owner as a dealer and the lots as inventory. Inventory does not qualify.

Splitting off a single parcel and selling it to one buyer usually looks very different from running a lot sale business. Factors that tend to matter include how long you have owned the land, why you are selling, how much development work you did, and how many sales there have been. If a buyer wants you to obtain zoning changes or do improvements before closing, discuss the effect with your CPA first.

Does selling part of your home's land qualify?

Land that is part of your primary residence is personal use property, not investment property, so it generally does not qualify for a 1031 exchange even if you sell it separately. In some situations the home sale exclusion under Section 121 may apply to vacant land next to a home, but the conditions are specific and timing dependent.

A property used partly as a home and partly as an investment, such as a farm with a house on it, may need to be split between the two treatments. That allocation is a job for your CPA before the sale is priced.

What other partial interests can be exchanged?

Selling part of your land is not the only way to sell a piece of a property. Permanent easements, such as a conservation easement sold for value or a long term access easement, can in some cases be treated as real property interests. Mineral and water rights can also qualify depending on state law and how they are structured. Each of these raises its own like kind and valuation questions, so confirm the treatment before you commit to the sale.

What should you sort out before listing?

• ›Find the original purchase records and any appraisal close to the acquisition date
• ›Ask your CPA how basis will be allocated between the sold and retained portions
• ›Get the lender's partial release terms in writing early
• ›Check whether the buyer's conditions involve rezoning or improvements on your side
• ›Engage your Qualified Intermediary before the sale closes

The short version

Selling part of a property is generally compatible with a 1031 exchange, and it can be a sensible way to reposition some of your holdings without selling everything. The tax result depends on the basis allocated to the part you sell, on how any shared loan is paid down, and on whether the land still looks like an investment rather than inventory.
