Substantiating Charitable Contributions

The charitable deduction is one of the few places in the Code where doing everything right and keeping the wrong paperwork produces the same result as not giving at all. Section 170 conditions the deduction on specific proof, and the required proof escalates in tiers: a bank record for small cash gifts, a written acknowledgment from the charity at and above a statutory amount, a form filed with the return for noncash gifts above a further level, and a qualified appraisal above a higher one still. Courts have denied deductions for gifts nobody disputed were made, because the tier was not satisfied.

1.The tiers

The dollar levels marking each tier, and the percentage-of-income ceilings that cap how much can be deducted in a year, are set by statute and have been changed by Congress repeatedly — including temporarily during the pandemic years. Read the current figures from the statute and the IRS instructions rather than from memory or from an article that may predate the last amendment.

2.What the acknowledgment must say

• The name of the charitable organization.
• The amount of cash, or a description — not a valuation — of any property contributed.
• A statement of whether the organization provided any goods or services in return.
• If it did, a description and a good faith estimate of their value, so the donor can subtract it.
• If the only thing provided was an intangible religious benefit, a statement saying so.

The last two points define the quid pro quo problem. A donor who buys a table at a fundraising dinner has made a gift only to the extent the payment exceeded the value of the meal and entertainment, and the charity's acknowledgment must supply that estimate. The same logic reaches auction purchases, benefit concerts, and membership packages that carry real privileges. Valuing the charity's own good faith estimate is not the donor's job, but relying on a receipt that omits the statement is the donor's risk.

Caution: The disallowance for a missing or defective acknowledgment is total, not proportional. A canceled check, a bank statement, and the charity's testimony that the gift was received will not save a deduction where the required written statement was never obtained in time.

3.Qualified appraisals and qualified appraisers

Above the appraisal tier the statute stops accepting the donor's estimate. A qualified appraisal must be prepared in accordance with generally accepted appraisal standards, must be made not too long before the gift and not after the return is filed, and must contain a defined list of contents — a description of the property, its condition, the terms of the transfer, the valuation method, and the basis for the value reached.

A qualified appraiser must have earned an appraisal designation or met minimum education and experience requirements for the type of property, must regularly perform appraisals for compensation, and must be independent of the transaction. The donor, the recipient organization, the party who sold the property to the donor, and anyone employed by or related to them are all disqualified. A fee based on a percentage of the appraised value also disqualifies the appraisal.

Publicly traded securities are the significant exception, since their value is objectively ascertainable and no appraisal is required. Donating appreciated stock held long enough is one of the more efficient forms of giving for that reason, and the recipient's acknowledgment still applies.

4.Where the deduction fails on grounds other than paperwork

Substantiation is only half the analysis. Several categories are not deductible however well documented. The value of donated services is not deductible, though unreimbursed out-of-pocket costs incurred while volunteering generally are. A gift of the right to use property, without transferring the property, is not deductible. Contributions to an individual, however sympathetic the circumstances, are not deductible, and neither are gifts to most foreign organizations.

Household goods and clothing must generally be in good used condition or better, unless a qualified appraisal supports the claimed value. And a contribution made with strings attached — where the donor retains control over how the property is used or can direct its return — may not be a completed gift at all.

Businesses face a further division. A payment to a charity that buys advertising, sponsorship visibility, or another commercial benefit is generally a business expense rather than a contribution, and it is deducted under a different provision with different proof requirements; the agency's guidance for business filers sits on the Small Business and Self-Employed Tax Center.

5.State treatment does not automatically follow

Section 170 governs the federal deduction. Whether a state allows a charitable deduction, and on what terms, is a matter of that state's law. States with an income tax generally begin from a federal figure — federal adjusted gross income or federal taxable income — but they then add back or modify items, and a state may decline to follow a federal change in the charitable rules. A few states offer credits rather than deductions for gifts to particular in-state organizations, such as scholarship funds or endowments, and those credits carry their own certification paperwork independent of anything the IRS requires.

The practical consequence is that a donor who itemizes federally may or may not get state relief for the same gift, and a donor who takes the federal standard deduction may still be able to deduct or claim a credit at the state level. Because state substantiation rules are usually written by reference to the federal ones, the federal paperwork is worth keeping even in a year when it yields no federal benefit.

6.Questions this raises

Does an annual giving statement from my church cover every gift?

Only if it does the work the statute requires. A year-end statement listing each contribution by date and amount, with the goods-and-services statement included, can satisfy the acknowledgment rule for each individual gift. A statement showing only an annual total does not, because the requirement is tested per contribution. Ask for the itemized version, and ask before the return is filed rather than afterward.

I gave through a donor advised fund. Who acknowledges the gift?

The sponsoring organization that holds the fund, because that is the charity receiving your contribution. Its acknowledgment must confirm it has exclusive legal control over the contributed assets. The later grants from the fund to operating charities are not your contributions and generate no deduction for you, which is why acknowledgments arriving from grant recipients should not be filed as substantiation.

Can I deduct mileage driven for a charity?

Unreimbursed transportation costs incurred in giving services to a qualified organization are generally deductible, either as actual expenses or at a standard rate the IRS publishes for charitable use. The rate differs from the business mileage rate and is set by statute rather than adjusted annually, so check the current figure. Keep a contemporaneous log of dates, destinations, and purpose; reconstruction after the fact is regularly rejected.

What if the charity turns out not to be tax-exempt?

The deduction generally fails, since section 170 requires a qualified recipient. The IRS maintains a searchable database of organizations eligible to receive deductible contributions, and checking before giving takes moments. There is limited protection for donors who gave in good faith before an organization's status was publicly revoked, but the safe course is verification at the time of the gift.

7.Building a file that survives review

1. Verify the recipient's status in the IRS database before giving, and note the date checked.
2. Ask for the acknowledgment at the time of the gift. Charities issue them routinely; the failure is almost always the donor waiting until spring.
3. Read what the acknowledgment says about goods and services. If the statement is missing, ask for a corrected letter before filing.
4. Photograph noncash property and keep the acquisition record showing when and how you got it and what it cost. Form 8283 asks for all of it.
5. Commission the appraisal early where the value will cross the appraisal tier, since it must predate the filing and the appraiser's signature is needed on the form.
6. Keep the file with the return, not with the charity. The burden of production is the donor's, and organizations reorganize and lose records.

These habits mirror the recordkeeping described in business expense and home office deductions, and the reasoning is the same: the deduction is only as good as the contemporaneous paper behind it. If a deduction is later disallowed and the year becomes underpaid, the installment consequences run through estimated tax payments and the underpayment penalty; if a deduction was missed in a closed year, the route and its deadline are covered in amending a return and the refund statute of limitations. Current forms, thresholds, and the exempt organization search tool are published by the agency at irs.gov, and audit procedure is described on its examination pages.
