An installment sale is a way of selling an asset that calls for the seller to receive payments over time rather than in a single lump sum. This type of sale is commonly used in real estate and business transactions. It can allow the seller to spread out capital gains taxes and potentially reduce their overall tax liability. The IRS permits installment sales under Section 453 of the Internal Revenue Code, but transactions have to meet specific requirements to qualify.
Consulting a financial advisor can help sellers structure their agreement and ensure compliance with IRS regulations.
What Is an Installment Sale?
An installment sale is a financial arrangement in which the seller agrees to receive payments over multiple years or another period of time rather than collecting the full purchase price upfront. This type of transaction allows for flexible financing terms and is often used for sales of real estate, businesses and other high-value assets.
Installment sales may provide some tax benefits as well. The delayed payment structure spreads out capital gains tax, reducing the tax burden in any single year. Instead of recognizing the profit all at once, the seller reports a portion of the principal and interest income as payments are received.
The IRS limits the type of transactions that qualify for this treatment. Under IRS rules, an installment sale must involve at least one payment received in a tax year following the sale.
The restrictions mean many sales won’t receive installment sale treatment for tax purposes. Transactions involving inventory, stocks, bonds and depreciable property sold to related parties generally do not qualify. Sellers can also opt out of installment reporting and recognize the entire gain in the year of sale if they prefer.
How an Installment Sale Works
An installment sale allows the buyer to take ownership of an asset while making payments over time. The seller finances part or all of the purchase, and then collects the payments. These payments typically include principal and interest. This arrangement is often used in high-value sales of real estate and businesses, because buyers may not have immediate access to the full purchase price.
For example, say a seller agrees to sell a commercial property for $500,000. The terms state that $100,000 is to be paid upfront, with the remaining $400,000 paid over 10 years at an interest rate of 5% per year. Instead of paying capital gains taxes on the full $500,000 in the year of sale, the seller only pays taxes on the portion of the gain received each year.
The seller’s taxable income includes:
- A portion of the principal repayment is taxed at the capital gains rate.
- The interest earned on the unpaid balance is taxed as ordinary income.
This structured payment approach can help sellers avoid a significant tax burden in the year of the sale. It also lets buyers finance the purchase with less immediate capital. Consulting a financial advisor can help ensure an installment sale is structured to maximize tax advantages while remaining compliant with IRS regulations.
What’s Required for an Installment Sale
Installment sales can qualify for tax deferral under IRS rules only by meeting several requirements. These requirements help ensure that the transaction is structured properly and that the tax benefits are applied correctly:
- At least one payment must be received in a future tax year: The seller must receive at least one payment after the tax year in which the sale occurs. If all payments are received in the same tax year, the transaction does not qualify for installment sale tax treatment.
- The sale cannot involve inventory or marketable securities: Installment sale treatment is reserved for capital assets such as real estate or businesses. Sales of inventory, stocks, bonds or securities do not qualify, since they are considered ordinary income transactions.
- The seller must recognize interest income on deferred payments: If the buyer makes payments over time, the seller is required to charge an appropriate interest rate. If no interest is charged, the IRS may impute interest. This means they assume an interest rate and tax the seller as if they received that amount of interest as income.
- A formal agreement must outline payment terms: The installment sale contract should include a detailed payment schedule, interest rate (if applicable) and consequences of default. This ensures that both parties understand their financial obligations.
- Depreciation recapture might apply: If the property being sold includes depreciable assets, any depreciation recapture must be recognized as ordinary income in the year of sale rather than spread out over time. This applies to buildings, machinery and equipment that have been depreciated for tax purposes.
What Are the Benefits of an Installment Sale?

An installment sale offers several financial and tax advantages. It often particularly appeals to sellers who want to defer capital gains taxes and increase the likelihood of closing a sale by offering financing options to buyers. Some of the benefits include:
- Tax deferral and potentially lower tax rates: By spreading taxable income over multiple years, sellers may remain in a lower tax bracket. This can reduce their overall tax liability. Instead of paying capital gains tax on the entire amount upfront, they recognize smaller amounts over time.
- Improved cash flow for buyers and sellers: Buyers can acquire high-value assets with smaller initial payments, making transactions more feasible. For sellers, installment payments provide a steady stream of income rather than a single lump sum.
- Ability to charge interest on deferred payments: Sellers can structure the deal with interest on the remaining balance, creating an additional income stream The IRS requires that installment sales include an appropriate interest rate to prevent tax avoidance.
- Flexibility in structuring the deal: Installment sales allow sellers and buyers to negotiate payment terms that benefit both parties. This can be especially helpful for business sales or real estate transactions where buyers may not have full funding available immediately.
- Increased likelihood of selling assets: Offering installment financing can make it easier for buyers to afford high-value assets. This expands the pool of potential buyers and increases the chances of a successful sale.
Frequently Asked Questions
What Happens If the Buyer Defaults on Payments?
If a buyer defaults, the seller may have the right to reclaim the property or take legal action to collect unpaid amounts. The IRS has rules for handling defaulted installment sales, including potential recognition of remaining gains as income.
Can a Seller Choose to Pay All Taxes in the Year of Sale?
Yes, sellers can opt out of installment sale treatment by electing to recognize the full gain in the year of sale. This is done by reporting the entire sale amount as income on their tax return, rather than using Form 6252.
How Are Installment Sale Payments Reported for Tax Purposes?
Sellers must file Form 6252 (Installment Sale Income) with their tax return each year, reporting the portion of the payment that consists of capital gains, interest and return of principal.
Bottom Line

An installment sale offers a tax-efficient way to sell real estate, businesses or other high-value assets while spreading out the tax liabilities over multiple years. This strategy provides tax deferral and improved cash flow for sellers. Buyers also get flexible financing, so it helps both parties. IRS rules restrict tax benefits to transactions that follow specific rules. This calls for including structuring payments properly and charging interest on deferred amounts.
