453 Sale
Definition:
A 453 sale, also known as an **installment sale**, is governed by **Internal Revenue Code Section 453**. It allows taxpayers to report and pay taxes on the gain from the sale of property over time as payments are received, rather than recognizing the entire gain in the year of sale. This method helps spread the tax liability and improve cash flow for sellers.

453 Sale Information
Under Section 453, an installment sale occurs when at least one payment is received after the tax year in which the sale occurs. The seller recognizes gain proportionally as each payment is received, based on the **gross profit ratio**, which is the gross profit divided by the total contract price.
Eligible property includes real estate, business assets, and certain personal property. However, inventory, publicly traded securities, and certain dealer property do not qualify for installment sale treatment. Interest income on deferred payments is also taxable and must be reported separately.
This approach benefits sellers by deferring part of the tax burden and potentially keeping them in a lower tax bracket.
Florida Legal Definition
In Florida, Section 453 sales follow **federal tax law**, as Florida does not impose a personal income tax. Sellers of Florida real estate or business interests can use the federal installment method to defer recognition of taxable gain for federal purposes.
While Florida imposes **documentary stamp taxes** on property transfers, the timing of these taxes is not affected by the installment sale method—stamp taxes are due at the time of transfer, regardless of when payments are received.
How It’s Used in Practice
In practice, a 453 sale is commonly used in real estate transactions, business sales, or other large asset transfers. The buyer agrees to make payments over time, and the seller reports a portion of the gain with each payment. Attorneys and tax professionals draft **installment sale agreements** that specify payment schedules, interest rates, and security provisions.
For example, a Florida property owner selling investment real estate may use a 453 sale to defer federal capital gains tax and receive steady income over several years. The installment method is reported on **IRS Form 6252 (Installment Sale Income)**.
