IRS Charitable Donation Audit Response Guide Checklist

• You received an IRS audit notice (Letter 566 or Letter 525) questioning your charitable

deduction claims

• You claimed philanthropic donations of cash, property, vehicles, or securities on your

federal tax return

• You are being asked to prove donations were made to qualified organizations
• You need to substantiate the value and documentation of your charitable contributions

This checklist does not apply if

• You have not filed a tax return claiming charitable deductions
• Your audit involves only income, credits, or business deductions unrelated to

philanthropic donations

• You have already completed the audit, and the IRS issued a final determination
• You are dealing with state tax issues rather than federal tax issues

Understanding Charitable Contribution Audits

A charitable contribution audit examines whether donations you claimed as tax deductions qualify under federal law and were properly documented. The IRS focuses primarily on contemporaneous written acknowledgment—your written proof obtained at or near the time of donation.

The IRS verifies the organization’s qualified status, the quality of your documentation, and the valuation methods used for non-cash gifts. Most audit failures occur not from a lack of proof that you gave something, but from missing written acknowledgments for cash donations or improper valuation of non-cash items.

Step-by-Step Charitable Contribution Audit Response

Checklist

1. Step 1: Locate Your Audit Notice and Identify Key Details

   Find your IRS audit notice, typically Letter 566 or Letter 525, and write down the exact tax year questioned, notice number, and response deadline date.

2. Step 2: Cross-Reference Your Tax Return with Questioned Items

   Pull your filed return copy and identify which specific donations correspond to the amounts listed in the audit notice to clarify any reporting discrepancies between records.

3. Step 3: Organize Donations into Four Categories

   Separate your contributions into cash, property, vehicles, and securities categories, as each has different IRS substantiation rules that will affect your audit response organization.

4. Step 4: Verify Each Charity’s Qualified Status

   Visit the IRS Tax Exempt Organization Search online and confirm each charity held qualified

   501©(3) or equivalent status during your donation year, as unqualified organizations disallow deductions entirely.

   Donations of $250 or More

   Locate the charity’s written statement obtained by your tax filing deadline showing the donation amount and whether you received goods or services in return for the contribution.

   Gather the charity’s receipt acknowledging what was received, along with your fair market value documentation, including photos, appraisals, comparable sales data, or thrift store price guides.

8. Step 8: Verify Vehicle Donation Form 1098-C for Donations Over $500

   If you donated a vehicle valued at over $500, locate Form 1098-C from the charity, which should show vehicle details and the sale price or an intended use statement.

9. Step 9: Confirm Form 8283 Requirements for Non-Cash Donations

   File Form 8283 Section A for non-cash donations totaling over $500 but not exceeding $5,000, and Section B with a qualified appraisal for donations exceeding $5,000.

10. Step 10: Organize All Documentation Chronologically

    Arrange documents in order by donation date in a binder or a PDF file with tabs that identify each charity, amount, and category for easy review by the examiner.

11. Step 11: Create a Summary Cover Sheet

    Prepare a single-page table listing donation date, charity name, amount claimed, category, and corresponding documentation provided to guide the examiner through your substantiation materials.

12. Step 12: Submit Your Response Before the Deadline

    Mail or electronically file your response as specified in the audit notice before the deadline, using certified mail or delivery confirmation, and retain proof of timely submission.
