Charitable Deductions in an IRS Audit

What the IRS checks on a charitable deduction

A charitable deduction is one of the easiest items for an examiner to test, because the law spells out the paperwork in advance. Publication 526 (2025) says you “must keep records to prove the amount of the contributions you make during the year,” and the kind of record depends on the amount and on whether you gave cash, property or out-of-pocket expenses. An examiner usually works through five questions:

1. Was the recipient a qualified organization? Churches, most public charities, and federal, state and local governments (for public purposes) qualify. The IRS’s Tax Exempt Organization Search shows whether a group is eligible. Gifts to individuals do not count, and Pub 526 says that includes gifts “earmarked for relief of a particular individual or family,” even through a charity.
2. Was it a gift, or did you get something back? If you received a dinner, ticket or other benefit, only the amount above its value is deductible. Publication 1771 uses a charity concert as its example: the deduction is the payment minus the fair market value of the ticket, and the charity must tell you that value in writing when you pay more than $75.
3. Was it given in that year? A deduction belongs to the year you actually paid: a mailed check counts on the mailing date and a credit card gift in the year of the charge.
4. Is the value right? Property is deducted at fair market value, with adjustments for property that has gone up in value. This is where clothing, household goods and appraised property get cut.
5. Do the records meet the substantiation rule for that size of gift? The rules in the next section are strict: a real gift can still be disallowed if the right document is missing.

The examiner may also check the deduction limits based on your adjusted gross income; amounts over a limit carry forward up to 5 years (15 for qualified conservation contributions), per Pub 526. For tax years through 2025 the deduction required itemizing on Schedule A.

The substantiation rules, by type and size of gift

These are the records Publication 526 (2025) requires. Separate gifts are not added together for the $250 test: weekly gifts of $25 are each their own gift. For the noncash $500 test, however, similar items given during the year are combined.

Pub 526 says the noncash rules above $500 also apply to returns for any carryover year, so keep the papers until the last year you use the deduction is past the audit period.

The written acknowledgment and its timing trap

IRC 170(f)(8) says that “no deduction shall be allowed” for any contribution of $250 or more unless you have a contemporaneous written acknowledgment from the charity. According to Publication 1771, the acknowledgment must give:

• the charity’s name;
• the amount of any cash gift, or a description (not the value) of property;
• whether the charity gave you any goods or services in return, and if so a description and good-faith estimate of their value, or a statement that you received only intangible religious benefits.

A letter, postcard, email or computer-generated statement works, and one annual summary can cover several gifts. You do not attach it to the return; you keep it.

If the charity did send a timely acknowledgment and you lost it, ask the charity for a copy of what it issued and when. Charities usually send them by January 31 of the next year, Pub 1771 notes, so a donor portal or the charity’s records often still have it.

Noncash gifts: value, Form 8283 and appraisals

Most charitable adjustments in an audit are about value, not about whether the gift happened. Publication 561 (12/2025) says used clothing and other personal items “are usually worth far less than the price you paid for them,” and that what buyers actually pay in used clothing stores, “such as consignment or thrift shops, is an indication of the value.” Clothing and household items also must be in good used condition or better to be deductible at all (IRC 170(f)(16)).

• Form 8283 missing. Pub 526 says the IRS “may disallow your deduction for noncash charitable contributions if it is more than $500 and you don’t submit Form 8283 with your return.”
• Qualified appraisal problems. For gifts over $5,000, the appraisal must follow appraisal standards, have a valuation date no earlier than 60 days before the gift, carry no prohibited fee, and be received before the return’s due date (including extensions). An appraisal by someone barred from practice before the IRS in the prior 3 years is disregarded as to value.
• Art. For art claimed at $20,000 or more, Pub 561 says the qualified appraisal must be attached to Form 8283.
• Vehicles. When the charity sells a donated car without significant use or improvement, the deduction is generally limited to the gross proceeds on Form 1098-C. Pub 526’s example: a car with a $6,000 guide value that the charity sold for $2,900 gives a $2,900 deduction.

Overstating value carries its own penalty. Pub 526 says the accuracy-related penalty is 20% (IRS.gov, 2026) of the underpayment caused by the overstatement if the value or basis claimed is 150 percent or more of the correct amount, and 40 percent if it is 200 percent or more; either applies only when the overstatement causes an underpayment of more than $5,000 (IRC 6662(e) and (h)). Appraisers face a separate penalty under IRC 6695A.

Conservation easements are a specialist area. The IRS treats certain syndicated conservation easement deals as listed transactions (Notice 2017-10), and Pub 526 explains that a partnership or S corporation easement claimed at more than 2.5 times the members’ basis is generally disallowed. If your audit involves one, get a professional who handles them.

Common audit adjustments

When the change increases tax, the examiner may add the accuracy-related penalty for negligence or for a substantial understatement, which for individuals means an understatement greater than 10 percent of the correct tax or $5,000, whichever is greater (IRC 6662(d)). Treasury Regulation 1.6662-3(b)(1) says negligence includes failing “to keep adequate books and records or to substantiate items properly.” The IRS can remove the penalty if you show reasonable cause and good faith.

How to respond to an audit of charitable deductions

1. List every gift you claimed. Break the total on Schedule A into individual gifts: date, charity, amount, cash or property.
2. Match each gift to the record its size requires. Use the table above. Pull canceled checks and card statements for cash, and the acknowledgments for every gift of $250 or more.
3. Ask charities for copies of what they issued. Request duplicates of acknowledgments and annual giving statements, and ask the date the original was sent.
4. Support property values. Gather your item lists, photos, condition notes, Forms 8283 and 1098-C and any appraisal. Our guide to an audit with missing records covers rebuilding proof honestly; never create an acknowledgment or receipt after the fact.
5. Answer by the date on the letter. Send copies, not originals, organized to match the request, with our audit response cover letter. If you need more time on a mail audit, the IRS says to fax a written request to the number on the letter and that it can ordinarily grant a one-time 30-day extension.
6. Review the result. If the examiner proposes changes, you will get a report and a 30-day letter. Our guide on whether to agree or appeal explains your options; value disputes are a common subject for Appeals.

Charitable deductions often come up in a mail audit; see types of IRS audits and the Letter 566 page if that is the letter you have. A CP2000 is not an audit of deductions; it is an income-matching notice.

Doing it yourself, free help, and when to hire someone

If your gifts were cash and you have the bank records and acknowledgments, you can usually answer the audit yourself. Help is worth it when large property gifts, appraisals, art, a conservation easement or several years are involved, or when the examiner proposes a valuation penalty.

• Taxpayer Advocate Service: free help if an IRS problem causes hardship or normal channels have failed, 877-777-4778 (IRS.gov, 2026).
• Low Income Taxpayer Clinics: LITCs represent eligible taxpayers in audits for free or a small fee.
• A representative under Form 2848: an enrolled agent, CPA or attorney can deal with the examiner for you; see when audit representation is worth it.

Global Gate Tax Relief’s team includes licensed tax attorneys, enrolled agents and CPAs. The consultation is free; if it takes the case it quotes a flat fee upfront, and no outcome is guaranteed. Request a free case review or call 1-877-800-8180.
