A bargain sale is two transactions on one contract: the donor sells the asset to charity for less than FMV. The IRS treats the portion sold for cash as a part sale (gain recognized on the proportionate basis) and the portion given as a part gift (charitable deduction for FMV minus sale price). It's the right tool when the donor has highly-appreciated real estate, closely-held stock, or art — wants to support a charity — but cannot afford to walk away from 100% of the asset's liquidity.
The economics of bargain sale work best on long-held, highly-appreciated property where the donor needs partial liquidity but wants the charitable benefit.
Sale price to charity must be less than FMV (or it's just a sale, no charitable component). Common ratios: charity pays 25%-60% of FMV — the donor gets that as cash, charity gets the remainder as a gift.
Marginal tax rate determines the value of the deduction. AGI determines how much of the deduction is usable in year 1.
Public charity vs private foundation drives the AGI ceilings. Related-use rule applies to tangible personal property (art, collectibles).
Bargain sale vs outright donation vs outright sale — net-cash-to-donor side-by-side.
The Institute publishes practitioner reference. No signup, no email capture, no sales call. If you're moving forward with a bargain sale, your next call is to a trust attorney and a qualified appraiser. We publish the framework so the conversation with your advisors is informed.

Estimates based on your inputs. Bargain-sale-to-charity transactions are governed by IRC §1011(b) (basis-allocation rule) and §170 (charitable deduction). Non-cash gifts over $5,000 require a qualified appraisal under §170(f)(11) and Treasury Reg §1.170A-17. The related-use rule under §170(e)(1)(B)(i) controls deductions for tangible personal property. Mortgage assumption is treated as part of the sale price for §1011(b) allocation purposes. The 30% / 20% / 60% / 30% AGI deduction ceilings vary by charity type and gift composition. State income-tax and transfer-tax treatment varies materially.
Consult your own qualified professionals before execution. Do not execute a bargain sale without (a) a trust/tax attorney experienced in §1011(b) bargain-sale design, (b) a qualified appraiser meeting §170(f)(11) requirements for non-cash gifts over $5,000, and (c) a CPA who can model the basis allocation and AGI-ceiling carryforward in your specific tax year.
