Frequently Asked Questions (Charitable Real Estate Deductions)
What is a Charitable Bargain Sale and how does it work?
A Bargain Sale occurs when a property owner sells real estate to a 501(c)(3) charity for less than its certified Fair Market Value (e.g. selling a $300k property for $100k cash). Under IRC § 1011(b), the seller receives $100,000 in immediate cash liquidity while claiming a $200,000 charitable deduction for the donated equity spread.
What are the strict IRS Form 8283 appraisal requirements?
To claim a non-cash real estate deduction exceeding $5,000, the IRS mandates: (1) A "Qualified Appraisal" performed by a certified USPAP appraiser no earlier than 60 days before deed conveyance; (2) Attaching IRS Form 8283 signed by both the appraiser and the charity's authorized officer; and (3) Filing the full written appraisal report with your tax return if the deduction exceeds $500,000.
Can I donate property held inside an LLC or S-Corporation?
Yes. If the real estate is held in a pass-through entity (Partnership, LLC, or S-Corp), the charitable contribution passes through on Schedule K-1 to individual members/shareholders pro-rata based on ownership percentage, subject to individual 30% AGI limits.
