To value Goodwill donations for tax deductions, use each item’s fair market value on the day you gave it away — the price a willing buyer would actually pay for it used, in its current condition. That figure is almost always well below what you originally paid. What you need to prove the number, and which forms you file, depends on how much you’re claiming.
What Fair Market Value Actually Means
The IRS defines fair market value as the price an item would sell for on the open market between a willing buyer and a willing seller, with neither forced into the deal and both knowing the relevant facts.1Internal Revenue Service. Publication 561, Determining the Value of Donated Property For a used shirt, a used couch, or a used blender, that price reflects wear, age, and demand — not the tag price from when the item was new.
The most defensible way to arrive at a number is to look at what comparable items in similar condition have actually sold for. Check completed sales at thrift stores, consignment shops, and online resale platforms. Asking prices don’t count, because an unsold listing doesn’t prove anyone would pay that amount. Note the brand, model, condition, and sale price for a handful of comparables and keep those notes with your tax records. If the IRS ever questions your return, that documentation is what supports your figures.1Internal Revenue Service. Publication 561, Determining the Value of Donated Property
Items Have to Be in Good Used Condition
Federal law bars a deduction for clothing or household items unless they’re in “good used condition or better.”2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Stained clothing, broken small appliances, and worn-out shoes no reasonable buyer would purchase don’t qualify, no matter how many of them fit in the bag. There is one narrow exception: you can deduct an item that falls below that standard if you claim more than $500 for that single item and attach a qualified appraisal to your return.3Internal Revenue Service. Publication 526, Charitable Contributions
“Household items” for this rule covers furniture, appliances, linens, electronics, and other everyday goods. It does not include food, paintings, antiques, other objects of art, jewelry, gems, or collections, which have their own valuation rules.3Internal Revenue Service. Publication 526, Charitable Contributions
Records You Need at Each Dollar Level
The paperwork requirements step up as your claim gets larger. Meet the requirement for the tier you’re in and your deduction holds up.
Under $250
Get a receipt from Goodwill showing its name and address, the date and location of the drop-off, and a description of what you donated detailed enough that someone unfamiliar with the gift could identify it.3Internal Revenue Service. Publication 526, Charitable Contributions A generic “bag of clothes” won’t hold up. List items individually: “men’s wool coat,” “wooden coffee table,” “20-inch flat-screen television.”
$250 to $500
Any single contribution of $250 or more also requires a contemporaneous written acknowledgment from the charity. It has to describe the property, state whether Goodwill gave you anything in return, and estimate the value of anything you received back. You need this acknowledgment in hand by the earlier of the date you file your return or the return’s due date with extensions.4Internal Revenue Service. Substantiating Charitable Contributions
Over $500
Once your total noncash contributions for the year exceed $500, you must file Form 8283 with your return.5Internal Revenue Service. About Form 8283, Noncash Charitable Contributions Section A covers items or groups of similar items valued at $5,000 or less and asks for the charity’s name and address, a description of the property, the date of the gift, and how you determined fair market value.
Over $5,000
For any single item, or group of similar items, valued above $5,000, you need a qualified written appraisal from a qualified appraiser, and you complete Section B of Form 8283.3Internal Revenue Service. Publication 526, Charitable Contributions Skip the form and the IRS generally disallows the deduction unless you can show the omission was due to reasonable cause rather than intentional neglect.6Internal Revenue Service. Instructions for Form 8283
Watch the grouping rule when deciding whether you’ve crossed $5,000. The IRS lumps similar items together even if you donated them to different charities. Similar items means property in the same general category, such as all clothing, all books, or all furniture. If your combined clothing donations across multiple charities total more than $5,000, the entire group needs an appraisal and Section B filing.6Internal Revenue Service. Instructions for Form 8283
Penalties for Overstating Value
Inflating what your items were worth can trigger an accuracy-related penalty. If the IRS finds that your claimed value was 150 percent or more of the correct value, the penalty is 20 percent of the resulting tax underpayment. At 200 percent or more, the penalty doubles to 40 percent.7Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments The penalty applies only when the portion of the underpayment tied to the overstatement exceeds $5,000 for the year.
Conservative valuations backed by comparable sales are the simplest protection. When an item could reasonably be worth $50 or $80, picking the lower figure gives you a legitimate deduction without inviting scrutiny.
You Have to Itemize for This to Help
Noncash donations reduce your tax bill only if you itemize on Schedule A instead of claiming the standard deduction. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your itemized deductions in total (mortgage interest, state and local taxes, charitable gifts, and so on) don’t clear that number, valuing your Goodwill donations won’t change what you owe.
A new above-the-line deduction starting in 2026 lets non-itemizers write off up to $1,000 ($2,000 if married filing jointly) in charitable contributions, but only for cash gifts.9Internal Revenue Service. Topic No. 506, Charitable Contributions Bags of clothing and used household goods don’t qualify under that rule.
Vehicles Follow Different Rules
If you’re donating a car, boat, or airplane through Goodwill’s vehicle program, the valuation approach above does not apply. When the charity sells the vehicle without significant use or material improvements, your deduction is generally capped at the actual sale price the charity receives, not Blue Book or private-party value.10Internal Revenue Service. IRS Guidance Explains Rules for Vehicle Donations Full fair market value is available only if the charity uses the vehicle significantly in its programs, makes major repairs that substantially increase its value, or gives or sells it at a steep discount to someone in need.
For any vehicle donation claimed above $500, the charity must send you Form 1098-C showing either the gross sale proceeds or a certification of how the vehicle was used, and you attach it to your return.11Internal Revenue Service. Instructions for Form 1098-C Without that form, the deduction is disallowed.
