Risk Management
Does claiming a large tax deduction for donated building materials increase your risk of an IRS audit? The honest answer is: it depends on your documentation.
Red Flags You Must Avoid
You cannot simply guess that your used kitchen cabinets are worth $10,000, or use the price of new cabinets at Home Depot as your baseline. You must use the Fair Market Value of the materials in their current condition — which is why a qualified appraiser is non-negotiable for deductions over $5,000.
If you donate more than $500 in non-cash items, you must file Form 8283. If the value is over $5,000, you must complete Section B, requiring signatures from the appraiser and the charity. Filing a return without this form is an automatic denial of the deduction.
You cannot receive a "quid pro quo" for your donation. If the deconstruction company "buys" the materials from you by reducing their bill, that is a sale, not a donation. The materials must be given freely to a non-profit.
The IRS aggregates similar items. You cannot donate $4,000 of lumber to Charity A and $4,000 of lumber to Charity B to avoid the $5,000 appraisal threshold — the IRS views that as $8,000 of "lumber," requiring an appraisal.
Build an Audit-Proof File
A USPAP-compliant report with photos, comparables, and methodology.
A Contemporaneous Written Acknowledgment (CWA) from the charity, dated on or before the day you file your return.
Detailed lists of exactly what was harvested during deconstruction.
The Role of DDP in Risk Mitigation
Working with a specialized program reduces risk. By overseeing the appraiser and the non-profit handoff, DDP ensures the evidence file is complete before you ever file your taxes.
FAQ
No. The IRS uses automated algorithms to flag returns that look unusual — a $200,000 non-cash charitable contribution on a tax return with $150,000 of income will trigger a red flag. A flag does not mean a penalty; it simply means the IRS wants to check your math. If your documentation is bulletproof, you have nothing to fear.
Retain the USPAP-compliant appraisal, the donee's Contemporaneous Written Acknowledgment, detailed material inventories, photographs, and project correspondence. Keep them for as long as the return remains open, including carry-forward years.
The appraiser stands behind the appraisal, and DDP produces the underlying project records establishing an unbroken chain of custody. Representation before the IRS is handled by your own tax professional or counsel.

A large tax deduction is a privilege, not a right. The IRS is vigilant against abuse but respectful of compliance.
