What Is an Installment Sale for Real Estate?

An installment sale real estate transaction occurs when you sell property and the buyer pays you in two or more installments. This differs from a traditional cash sale where payment is received immediately at closing. Under Internal Revenue Code Section 453, you can elect to report gain as you receive payments rather than recognizing all gain in the year of sale.

For example, if you sell a rental property for $500,000 and receive $100,000 down with the remaining $400,000 paid over the next four years, you recognize gain proportionally each year. This spreads your taxable income across multiple tax years, potentially keeping you in lower tax brackets.

Key Requirements for an Installment Sale

• Multiple Payments: At least one payment must be received after the year of sale.
• Debt Instrument: The sale must be evidenced by a promissory note or written agreement showing payment terms.
• No Related-Party Sale: Section 453 does not apply to sales between related parties (spouses, children, trusts you control).
• Not a Dealer Sale: If you’re a real estate dealer, you may not qualify for installment sale treatment on some sales.

Why Installment Sale Real Estate Matters in 2026

With the current capital gains tax rates in place for 2026, spreading your income recognition becomes increasingly valuable. The 15% capital gains rate applies to single filers with income between $44,626 and $492,300, while married couples filing jointly reach the 15% bracket between $89,251 and $551,800. By recognizing gains over multiple years, you maintain control over your marginal tax rate.

How Does Tax Deferral Work With Installment Sales?

The tax deferral in an installment sale works through the gross profit ratio calculation. This formula determines what percentage of each payment represents taxable gain versus return of your investment basis.

Calculating Your Gross Profit Ratio

The gross profit ratio is calculated as follows:

Component	Definition	Example ($500K Sale)
Sale Price	Total amount buyer agrees to pay	$500,000
Adjusted Basis	Original cost less accumulated depreciation	$250,000
Gross Profit	Sale Price minus Adjusted Basis	$250,000
Gross Profit Ratio	Gross Profit ÷ Sale Price	50%

In this example, 50% of each payment received is taxable gain, while 50% is return of basis. This means when you receive a $100,000 payment, $50,000 is recognized as taxable gain and $50,000 is nontaxable basis recovery.

Year-by-Year Gain Recognition Example

Using the $500,000 property sale with $100,000 down payment and $100,000 annual payments over four years:

Year	Payment Received	Recognized Gain (50%)	Basis Recovery (50%)	Cumulative Gain
2026 (Year 1)	$100,000	$50,000	$50,000	$50,000
2027 (Year 2)	$100,000	$50,000	$50,000	$100,000
2028 (Year 3)	$100,000	$50,000	$50,000	$150,000
2029 (Year 4)	$100,000	$50,000	$50,000	$200,000

Notice that by year 2029, you’ve recognized the full $250,000 gain over four years. Without depreciation recapture considerations, this spreading of income allows you to manage your tax brackets more strategically.

What Are the Income Recognition Requirements?

Beyond the gain recognition on payments, installment sale real estate transactions trigger additional income recognition requirements. These include both the proportional gain calculation and additional interest income obligations.

Interest Income on the Seller-Financed Note

When you carry back financing (become the lender), IRS regulations require that a “reasonable” interest rate be charged on the note. For 2026, the IRS Applicable Federal Rate (AFR) sets safe harbor interest rates. If you charge less than the AFR, the IRS will impute interest income to you.

Let’s say you sell the $500,000 property with $100,000 down and $400,000 financed at 4% annual interest (the typical AFR range for 2026). You would recognize:

• Proportional capital gain on principal payments
• Interest income on the outstanding balance ($16,000 in year one on $400,000 balance)

Imputed Interest Rules (Section 483)

If you don’t charge interest or charge below-market rates, Section 483 of the Internal Revenue Code requires that interest be imputed. This means even if you didn’t actually receive or charge interest, the IRS will deem you to have received interest income, and you’ll owe taxes on it.

How Do You Avoid Depreciation Recapture Pitfalls?

This is the most critical mistake real estate investors make with installment sales. While you defer capital gains tax on your profit through installment reporting, depreciation recapture is treated differently. The depreciation you claimed on the property over the years must be “recaptured” and taxed at a 25% rate in the year of sale—not spread across installment years.

Understanding Section 1250 Recapture

When you sell residential rental property, all depreciation claimed is subject to 25% recapture tax. For commercial property, depreciation taken after May 12, 1997, is generally subject to the same 25% recapture rate.

Here’s the critical issue: If you sold the $500,000 property with $100,000 in accumulated depreciation, you recognize:

• 2026 (Year of Sale): $100,000 depreciation recapture taxed at 25% = $25,000 tax immediately due
• 2026-2029: Capital gain on the remaining $250,000 profit spread proportionally across installments

Planning Strategy: Accounting for Recapture Taxes in Seller Financing

Because depreciation recapture is due immediately, you must plan for cash to pay this tax in the year of sale. Receiving only a $100,000 down payment won’t cover the depreciation recapture if it’s $25,000 or more. Consider structuring the down payment to cover anticipated depreciation recapture taxes.

What Is Form 6252 and How Do You File It?

For each year you receive installment payments, you must file Form 6252 with your tax return. This form calculates and reports the taxable gain recognized for that tax year based on the payments received.

Key Information Required on Form 6252

• Date of sale and property description
• Selling price and adjusted basis
• Total gain on the sale
• Gross profit ratio
• Payments received in current year
• Taxable gain to report on Schedule D (Capital Gains and Losses)

Filing Form 6252 correctly is essential. Errors can trigger IRS notices, penalties, and interest charges. Make sure you have detailed records of all payments received, including both principal and interest components.

Comparing Installment Sales to 1031 Exchanges: Which Is Better?

Real estate investors often compare installment sales to IRC Section 1031 like-kind exchanges. Both strategies reduce immediate tax burden, but they work very differently. Let’s examine the critical differences:

Installment Sales vs. 1031 Exchanges: Head-to-Head Comparison

Feature	Installment Sale	1031 Exchange
Tax Treatment	Defer gain recognition over multiple years	Eliminate tax completely on reinvested proceeds
Reinvestment Requirement	No—you control use of proceeds	Yes—must identify and purchase qualifying property within 180 days
Timeline	Flexible—can span many years	Strict—45-day identification, 180-day close deadlines
Depreciation Recapture	Taxed at 25% in year of sale	Deferred until later disposition (if qualified)
Qualified Properties	Any real property can be sold	Must be “like-kind” property (real estate to real estate)
Cash Requirements	Down payment covers only a portion of proceeds	Must reinvest equal or greater value within 180 days

When to Use Each Strategy

Choose an installment sale if: You’re retiring, downsizing your portfolio, or don’t want to reinvest immediately. You prefer to manage income recognition across multiple tax years.

Choose a 1031 exchange if: You want to continue building your real estate portfolio and can meet strict reinvestment timelines. You want to defer depreciation recapture as well as capital gains.

 

Uncle Kam in Action: Real-World Success

Client Profile: Marcus, a 58-year-old real estate investor with a $2.8 million portfolio of five rental properties across California and Texas. Marcus had accumulated $680,000 in depreciation deductions over 15 years and was ready to transition toward retirement over the next five years.

The Challenge: Marcus decided to sell his most valuable property, a multifamily complex with a $1,200,000 sale price. His adjusted basis was $600,000, creating a $600,000 capital gain. Additionally, $180,000 of accumulated depreciation would face immediate 25% recapture tax ($45,000). In a traditional cash sale, Marcus would owe approximately $105,000 in total federal taxes in 2026 alone (assuming combined federal + state rates around 17.5% on capital gains). This large one-time income could also trigger Alternative Minimum Tax considerations and Medicare premium increases, potentially costing an additional $8,000-12,000.

The Uncle Kam Solution: Rather than a cash sale, Marcus structured an installment sale real estate transaction with this buyer: $300,000 down payment, $300,000 financed over five years at 5% annual interest. This structure allowed Marcus to:

• Recognize 50% of the $300,000 down payment ($150,000) as capital gain in 2026, spread the remaining $300,000 capital gain over five years ($60,000 annually)
• Continue to earn 5% interest income on the note balance ($15,000 in 2026, declining annually)
• Pay the $45,000 depreciation recapture tax in 2026, but offset it with the $300,000 down payment
• Manage income recognition to maintain favorable capital gains tax brackets in years 2027-2030

The Results:

• Tax Savings: $23,000 in first-year federal taxes deferred (vs. paying $105,000 immediately in a cash sale), with an additional $42,000 deferred across years 2027-2030
• Medicare Premium Impact: By spreading income, Marcus avoided triggering higher Medicare premiums, saving approximately $8,500 over five years
• Investment Return: Marcus earned 5% interest on the financed portion, equivalent to $15,000 in 2026 declining, providing passive income during the transition to retirement
• Overall Value: Installment sale generated approximately $39,500 in combined tax savings and additional interest income in the first year, with Marcus paying only a one-time investment of approximately $3,000 in professional consultation fees to structure the deal correctly
• Return on Investment (ROI): 13.2x first-year return on professional services investment—Marcus’s strategic installment sale generated roughly $39,500 in measurable value for a $3,000 initial investment

This is just one example of how our proven tax strategies have helped clients achieve significant savings during property transitions.

Frequently Asked Questions

Can I Combine an Installment Sale With a 1031 Exchange?

Yes, you can use a reverse 1031 exchange to purchase replacement property while structuring the original sale as an installment sale. However, this creates complexity. For instance, you could acquire a new property in a 1031 exchange while financing the sale of the original property through an installment sale. This requires careful coordination with a qualified intermediary and tax professional to avoid disqualifying the 1031 exchange.

What if the Buyer Defaults on Installment Payments?

If the buyer defaults on payments, you have legal recourse through the promissory note (foreclosure, deficiency judgment, etc.). From a tax perspective, once you’ve recognized gain on a payment, you’ve already paid tax on it. If the payment never materializes, you may be able to claim a bad debt deduction, but this requires meeting strict IRS requirements for nonbusiness bad debts. Document all payment defaults carefully and consult a tax professional immediately if this occurs.

Does the Installment Sale Interest Rate Matter for Tax Purposes?

Absolutely. The interest rate matters significantly. You must charge at least the IRS Applicable Federal Rate (AFR) to avoid having interest imputed by the IRS under Section 483. Charging a lower-than-AFR rate can reduce the amount of interest income you recognize, but the IRS may recharacterize the transaction. For 2026, make sure your note’s interest rate meets or exceeds the current AFR (typically 4-5% depending on the note term).

Can I Use an Installment Sale for Land or Commercial Property?

Yes. Installment sale real estate transactions work for any type of real property—residential rentals, commercial buildings, vacant land, etc. The key difference is that land typically has no depreciation recapture (since land doesn’t depreciate), making installment sales particularly attractive for land holdings. Commercial property may have depreciation recapture depending on when the improvements were made.

What Income Level Is Required to Qualify for Installment Sale Treatment?

There are no income limits for using installment sale real estate strategies. Any taxpayer can use Section 453, regardless of whether you’re a high-income professional, retiree, or business owner. The strategy is available to all real estate investors equally.

How Does an Installment Sale Affect My Quarterly Estimated Tax Payments?

You must include anticipated installment sale income in your estimated tax calculations. If you receive a $100,000 payment in Q1 2026 and recognize $50,000 in gain, you should include this in your estimated tax for 2026. Failure to do so may result in underpayment penalties. Work with a CPA to recalculate estimated tax payments after closing on the property sale.

Are There State Tax Implications for Installment Sales?

Yes. Many states conform to federal installment sale treatment, but some have their own rules. California, for example, generally requires you to report all gain in the year of sale for state purposes, even though you may defer it federally. This creates a situation where you pay California tax on gain you haven’t yet received. Consult with a state tax specialist to understand your specific state’s treatment of installment sales.

What Happens to My Installment Sale Note If I Pass Away?

The note becomes part of your estate. Your estate (or heirs) continues to receive payments and report income on Form 6252. The buyer’s obligation doesn’t change. Ensure your will or trust clearly addresses who will manage the note and receive payments after your death, and consult an estate planning attorney about any implications.
