IRS Rules on Land Contracts for Buyers and Sellers

The IRS rules on land contracts treat the deal as an immediate sale with seller-provided financing, not as a rental or a deferred purchase, even though the seller keeps legal title until the buyer pays in full. That classification drives everything else: the seller reports gain on the sale (usually spread across years under the installment method) and pays ordinary income tax on interest received, while the buyer deducts mortgage interest and property taxes just like any homeowner with a bank loan.

Who the IRS Considers the Owner

The agency looks past the deed and asks which party carries the “benefits and burdens” of ownership. In almost every land contract, the buyer takes possession on day one, pays the property taxes and insurance, handles maintenance, and absorbs any drop in value. Those responsibilities are the hallmarks of ownership, so the IRS treats the buyer as the owner from the date the contract takes effect.

The practical result: the transaction is taxed as a sale with a seller-financed loan. The seller is treated as having sold the property and received a promissory note. The buyer is treated as a homeowner who borrowed from the seller. Every tax consequence flows from that framing.

How the Seller Is Taxed

Because a land contract spreads payments over years, it qualifies as an installment sale under Internal Revenue Code Section 453. An installment sale is any property disposition where at least one payment arrives after the tax year the sale closes.¹ The installment method lets the seller spread taxable gain across the years payments come in, rather than owing tax on the full gain upfront. Income from the contract splits into two streams: capital gain on the sale itself, and ordinary interest income on the financing.

Gross Profit Percentage

Each principal payment contains a taxable portion and a nontaxable return of basis. The taxable share is set by the gross profit percentage, calculated by dividing the gross profit (selling price minus the seller’s adjusted basis and selling expenses) by the total contract price.¹ That percentage stays the same for every payment year.

Suppose you sell land with a $200,000 contract price and your adjusted basis plus expenses is $120,000. Your gross profit is $80,000, giving you a gross profit percentage of 40%. For every $1,000 of principal collected, $400 is taxable gain and $600 is a return of your investment. The seller calculates this each year on Form 6252 and carries the gain to Schedule D.²

Interest Income

Interest the seller collects is taxed as ordinary income, separate from the installment gain calculation. Most sellers report it on Schedule B of Form 1040 if it exceeds $1,500.³ If the property was investment or business property, interest may instead appear on Schedule E or Schedule C depending on the seller’s level of activity.

Imputed Interest Under the Applicable Federal Rate

If the land contract charges no interest, or charges less than the Applicable Federal Rate, the IRS rewrites the deal. Under Sections 483 and 1274, the agency imputes interest at the AFR, shifting a chunk of what the contract calls “principal” into “interest.”⁴ The seller ends up with more ordinary income and less capital gain. The buyer gets a correspondingly larger interest deduction. Writing a low rate into the contract does not avoid this.

The AFR is published monthly by the IRS in three tiers based on the length of the note: short-term for obligations of three years or less, mid-term for over three through nine years, and long-term beyond nine years.⁵ Most land contracts fall under the mid-term or long-term rate. Current rates are posted on the IRS Applicable Federal Rates page.⁶

Depreciation Recapture

Sellers who previously claimed depreciation on the property face an extra layer of tax. Section 453(i) requires all depreciation recapture to be recognized in the year of the sale, regardless of whether any cash has been received yet.⁷ That recapture is taxed as ordinary income. Only the gain exceeding the recapture can be deferred under the installment method. This catches many sellers of rental property off guard, because they owe tax on recapture before the buyer has paid much of anything. Section 1250 governs how much of that recapture applies to real property that used accelerated depreciation.⁸

Home Sale Exclusion Under Section 121

Sellers who used the property as their primary residence for at least two of the five years before the sale can exclude up to $250,000 of gain ($500,000 for married couples filing jointly) under Section 121. The exclusion applies to installment sales. When the exclusion covers all the gain, the seller reports zero capital gain on Form 6252 each year while still reporting interest income as ordinary income.⁹

If the gain exceeds the exclusion, the seller applies the exclusion first and then uses the installment method for the remaining nonexcludable gain. Any depreciation recapture, including from a home office, must still be recognized in the year of sale and cannot be sheltered by Section 121.

Electing Out of the Installment Method

The installment method is the default, but a seller can choose to report the entire gain in the year of the sale. This can make sense when the seller expects to be in a higher tax bracket later or wants to simplify ongoing reporting. To elect out, the seller reports the sale on Form 8949 and Schedule D instead of Form 6252. The election must be made by the due date (including extensions) of the return for the year of the sale.⁷ Once made, the election can only be revoked with IRS consent, and the IRS will not approve a revocation if one of its purposes is avoiding tax.

How the Buyer Is Taxed

Because the IRS considers the buyer the economic owner from day one, the buyer gets the tax benefits available to anyone who bought a home with a bank mortgage: mortgage interest and property taxes, both claimed on Schedule A.

Mortgage Interest Deduction

The interest portion of each payment is deductible as qualified residence interest, provided the buyer itemizes. IRS Publication 936 specifically lists a land contract as a qualifying secured debt instrument, as long as it makes the buyer’s ownership security for repayment and provides that the property satisfies the debt in case of default.¹⁰ The deduction is limited to interest on the first $750,000 of acquisition debt ($375,000 if married filing separately) for contracts entered after December 15, 2017.¹¹

A catch trips up many land contract buyers. Because no bank or mortgage servicer is involved, the buyer will not receive a Form 1098 documenting interest paid. The buyer must instead report the interest on Schedule A, line 8b, and provide the seller’s name, address, and taxpayer identification number on the dotted lines next to that entry. Failure to include the seller’s TIN can trigger a $50 penalty.¹⁰ Both parties should exchange TINs using Form W-9 at or before closing.¹² If the seller refuses to provide a TIN, the buyer should still claim the deduction and attach a statement explaining the effort made to obtain it.

Property Tax Deduction

The buyer can deduct property taxes paid on the home, even if the contract requires the seller to collect the money and remit it to the local taxing authority. The state and local tax deduction is capped at $40,000 ($20,000 if married filing separately), with a phasedown for taxpayers whose modified adjusted gross income exceeds $500,000. At the highest income levels, the cap floors at $10,000.¹³ These thresholds are indexed for inflation and increase by 1% annually through 2029.

Tax Basis

The buyer’s basis is the full purchase price stated in the contract, plus qualifying closing costs. Interest paid over the life of the contract is not added to basis. Principal payments do not change it either, because those payments reduce the loan balance rather than the investment in the property. Capital improvements do increase basis and should be tracked carefully, since the total basis determines taxable gain when the buyer eventually sells.

Annual Reporting and the 1099 Question

The seller files Form 6252 every year the installment obligation exists, even in years no payment is received. The form calculates the recognized capital gain for that year, which flows to Schedule D.² Interest income is reported separately on Schedule B.¹⁴

One of the most misunderstood pieces of land contract reporting is who issues what to whom. In a typical land contract between individuals, the seller is generally not required to issue Form 1099-INT for the interest received. The IRS exempts interest on obligations issued by individuals from 1099-INT reporting requirements.¹⁵ This exemption applies to most private-party land contracts. The seller must still report the interest on their own return regardless of whether any information return was filed.

Family and Related-Party Sales

Selling property to a family member on a land contract invites extra scrutiny. Two sets of rules can apply, and most family sellers are not aware of either.

First, if you sell to a related party on an installment basis and that person resells the property within two years, the proceeds from the resale are treated as if you received them at the time of the second sale. This accelerates gain recognition and can wipe out the deferral the installment method was supposed to provide.⁷ Related parties include spouses, children, grandchildren, parents, siblings, and certain controlled entities. The rule does not apply if neither sale was motivated by tax avoidance.

Second, when the property is depreciable in the buyer’s hands and the buyer is a controlled entity (such as a business the seller owns more than 50% of), the installment method is flatly disallowed, and the seller must recognize all gain in the year of sale.⁷

There is also a gift tax angle. When a family land contract sets the price or interest rate below fair market value, the IRS may treat the difference as a gift. The gap between what a third-party buyer would pay (including market-rate interest) and what the family member actually pays is the gift amount. If that figure exceeds the annual gift tax exclusion ($19,000 per recipient for 2025, adjusted annually for inflation), the seller must file Form 709, even if no gift tax is actually owed thanks to the lifetime exemption. Combining a below-market price with a below-AFR interest rate can create a surprisingly large gift component that accumulates year over year.

Default and Repossession

When a buyer stops paying and the seller takes the property back, Section 1038 provides a specific formula for calculating the seller’s gain. The rules are mandatory and generally more favorable than the normal rules for a property disposition.

The seller’s recognized gain is limited to the lesser of two amounts. The first cap is the total cash and fair market value of other property received before repossession, minus any gain already reported as income in prior years. The second cap is the original gross profit from the sale, reduced by both previously reported gain and the seller’s repossession costs.¹⁶ The seller cannot claim a loss on repossession, and no bad debt deduction is available for the unpaid balance.

The defaulting buyer is treated as having disposed of the property in exchange for cancellation of the remaining debt. If the canceled debt exceeds the buyer’s adjusted basis, the buyer has taxable gain. If the property was used as a personal residence and its value dropped below basis, the resulting loss is generally not deductible under the personal-use property rules.

When the seller reacquires the property, the seller may need to issue Form 1099-A to the buyer, reporting the outstanding principal and the fair market value of the property as of the repossession date.¹⁷ If the seller also cancels $600 or more of the remaining debt, Form 1099-C may be required. When both events happen in the same calendar year, a single Form 1099-C can cover them.

Selling the Note or Taking a Balloon Payoff

A seller who holds an installment note can sell, exchange, or otherwise dispose of it before the buyer finishes paying. Section 453B treats this as a taxable event. The seller recognizes gain or loss equal to the difference between the note’s tax basis and the amount realized.¹⁸ Any gain retains its character as long-term capital gain if the property was held for more than a year before the land contract was executed. Gifting the note to someone other than a spouse triggers the same recognition rule, with the note’s fair market value standing in for the amount realized. A transfer to a spouse or incident to a divorce is generally nontaxable.

Many land contracts call for a balloon payment after several years of smaller installments, typically when the buyer refinances through a conventional lender. The balloon receives the same treatment as every other principal payment: the gross profit percentage sets the taxable portion, and the remainder is a return of basis. There is no special rate or penalty for a lump sum. The seller reports it on Form 6252 for the year received and carries the gain to Schedule D. After the payoff year, the seller has no further installment reporting obligations, though records should be kept in case of a future audit.
