How does Section 453 interact with the sale of a business asset that was previously subject to bonus depreciation or Section 179 expensing, impacting capital gains deferral?

When a business sells an asset for which **bonus depreciation** or **Section 179 expensing** was claimed, a portion of the gain is often recharacterized as ordinary income under the depreciation recapture rules (Sections 1245 and 1250). Section 453 generally defers the recognition of *capital gains* from an installment sale. However, the interplay with depreciation recapture is specific: any gain attributable to depreciation recapture *cannot* be deferred under Section 453.

Instead, the recapture amount must be recognized as ordinary income in the year of the sale, regardless of when the installment payments are received. This means that even if no cash is received in the year of sale for an asset that generated ordinary depreciation recapture, the seller will still owe tax on that recapture amount. After the recapture amount is fully recognized, any remaining gain on the asset can then be treated as an installment sale and deferred under Section 453. This significantly impacts cash flow planning for sellers, as they must account for an immediate tax liability even while the majority of the sale proceeds are deferred. Proper accounting and legal advice are critical to accurately calculate and plan for this immediate tax obligation.
