We are planning an installment sale under Section 453 to defer capital gains across several tax years, but our advisors raised concerns about depreciation recapture and interest charges. How does Section 453 actually affect our net proceeds and deal structure?

An installment sale under Internal Revenue Code Section 453 lets a seller defer recognizing capital gain until promissory note payments are actually received. This is a common tool to spread a taxable gain across lower tax brackets over multiple years. However, treating an installment sale as an automatic tax shield without modeling the specific statutory exceptions is a costly mistake.

First, Section 453 does not defer depreciation recapture. Under Section 1245 and Section 1250, any gain attributable to previously taken depreciation on equipment, machinery, or real estate is fully taxable as ordinary income in the year of sale, regardless of whether you received cash or an installment note. If you structure a transaction with minimal cash at closing and a massive installment note, you can face a massive ordinary income tax bill in April without the liquid cash on hand to pay it.

Second, beware of the Section 453A interest charge. If your total installment obligations arising during the taxable year exceed five million dollars, the IRS charges an annual interest fee on the deferred tax liability. This rule eliminates a major chunk of the financial benefit of large deferred installment notes.

Third, an installment sale shifts credit and default risk back onto you. If the buyer defaults three years into a seven-year note, you do not automatically get your taxes back. You enter expensive collection litigation and bankruptcy courts.

To protect your net proceeds, always demand enough cash at close to satisfy all immediate tax liabilities, including state taxes and full depreciation recapture. Treat the remaining installment note strictly as senior subordinated paper with a market interest rate that beats the statutory Section 453A borrowing rate.
