We are structuring a deal with a significant seller note and our CPA mentioned Section 453 installment treatment, but warned us about a surprise tax bill in year one. How does installment sale treatment actually work in an asset deal, and where do owners get burned?

Section 453 of the Internal Revenue Code allows sellers to defer capital gains taxes over the life of a promissory note, paying taxes only as principal payments are collected. In theory, this spreads your tax burden and keeps you out of the highest brackets in the transaction year. In practice, owners who sell assets rather than corporate stock often face an immediate, unfunded tax hit.

The trap lies in depreciation recapture under Section 1245 and Section 1250. Any gain attributable to previously taken depreciation on machinery, equipment, technology hardware, or leasehold improvements cannot be deferred under Section 453. The IRS mandates that all depreciation recapture must be recognized and paid in the tax year of the sale, regardless of how little cash was received at the closing table. Furthermore, inventory and accounts receivable are ineligible for installment reporting.

If you sell a capital-intensive or asset-heavy company for ten million dollars with six million in cash and four million in a seller note, your immediate tax liability could easily exceed the cash distributed once debt payoffs and transaction fees are settled. To protect yourself, run a precise tax model based on the purchase price allocation before signing the Letter of Intent. Structure the deal to mandate that cash at close covers all ordinary income liabilities and depreciation recapture, or push for a stock transaction where Section 453 applies cleanly across the full equity value.
