What the IRS expects when you donate and how to value it
When you give property instead of cash to a qualified charity, the IRS donation value rules control how much you can deduct. For 2017, the core standard is fair market value: the price property would sell for on the open market in an arm’s length transaction. This explainer outlines how the IRS defines fair market value, applies different rules by asset type and deduction size, and explains what records you must keep. It also details when you must itemize to benefit and how to treat any goods or services you receive in return. Use this guide to align your documentation with IRS expectations and reduce audit risk.
Fair market value and basic principles
Fair market value is the starting point for most noncash charitable gifts. In IRS guidance, this is the price property would change hands between a willing buyer and a willing seller, with both parties reasonably informed and neither under pressure to act. For publicly traded securities, this is usually the average of the high and low on the contribution date. For vehicles and other property, it may require an appraisal or credible third-party pricing sources. The deduction is generally limited to the fair market value of the item, not your cost basis or what you originally paid. Understanding this distinction helps prevent overstatement of value and supports a clearer audit trail.
Documentation expectations at different contribution levels
The IRS tiers recordkeeping and substantiation rules by the amount of your noncash contribution. For smaller donations under a certain threshold, a basic written acknowledgement from the charity may suffice. For larger noncash gifts, especially property worth more than a few hundred dollars, you typically need a qualified appraisal and additional documentation. The idea is that higher-value gifts require stronger evidence of value and ownership. These tiers exist to balance supportive detail with practicality for taxpayers. Keep the right level of records so you can respond to questions without carrying unnecessary paperwork.
Special rules for vehicles and related property
Vehicles attract particular scrutiny because valuation can vary widely. For 2017, if a charity sells a donated vehicle, your deduction is generally limited to the amount the charity actually receives from the sale. If the charity retains or makes material improvements to the vehicle before selling, different rules may allow you to claim a higher value. Similar concepts apply to boats and airplanes. The IRS emphasizes that claimed value should reflect what the property would reasonably bring in an arm’s length sale, not an optimistic projection. Using reputable charities and written sales disclosures strengthens your position and reduces dispute risk.
When an appraisal is necessary
Appraisals are commonly required for noncash gifts above certain thresholds, notably noncash property valued at more than $5,000 for the 2017 rules. The appraisal must be conducted by a qualified appraiser and include specific content, such as the property description, valuation methods, and the appraiser’s credentials. Form 8283 accompanies your return and reports noncash contributions; Part B of this form requires appraiser information for higher-value items. Filing an appraisal with your return is generally not necessary, but you must retain it with your records in case of examination. Treat the appraisal as a compliance tool, not just a one-time exercise.
| Attribute | Verified Detail (2017) | Source Type |
|---|---|---|
| Standard deduction vs itemizing | You must itemize to deduct charitable contributions | IRS Publication 526 |
| Vehicle sale limit | Deduction generally based on charity’s sale proceeds if sold within a short period | IRS Publication 526 and related notices |
| Appraisal threshold | Noncash property over $5,000 typically requires a qualified appraisal | IRS Form 8283 instructions (2017) |
| Publicly traded securities | Fair market value often the average of bid and ask on contribution date | IRS guidance on stock donations |
| Written acknowledgment | Charity must provide written acknowledgement for contributions $250 or more | IRS substantiation requirements |
Deduction limits and how AGI caps work
Even with correct valuation, your deduction can be limited by rules based on adjusted gross income. For example, donations of cash to public charities are generally limited to 60 percent of AGI in 2017, while gifts of capital gain property to the same charities may be capped at 30 percent of AGI. Contributions that exceed these caps can often be carried forward for up to five years. These limits apply regardless of how you determined the donation value, but they shape how much benefit you ultimately realize. Planning around caps can make the timing and choice of assets meaningful for your tax outcome.
Goods, services, and what you receive in return
If a charity provides goods or services in exchange for your contribution, only the excess over the fair market value of those benefits is deductible. For example, if you pay $200 for a charity dinner where the meal and event cost $60, you can generally deduct $140. The charity must provide a good-faith written disclosure describing the goods or services and their estimated value. This protects both you and the charity by making the deductible portion clear. Always review these disclosures and keep them with your records to support the amount you claim.
Recordkeeping and timing considerations
Strong records are the best defense when questions arise about donation value. For noncash gifts, this often means dated receipts, a description of the item, its condition, and either an appraisal (when required) or credible evidence of value. For contributions at year end, transfer dates and settlement times matter, because your deduction is tied to when the charity actually receives the gift. Electronic funds transfers, stock delivery instructions, and vehicle title transfers each have specific timing rules. Planning these steps well before the year closes reduces the chance that a technically correct donation falls outside your deduction window.
Common pitfalls and practical checks
Overvaluing noncash items, failing to itemize, and missing acknowledgment thresholds are among the most common missteps. A few practical checks can help: compare similar sold listings for used goods, obtain a dated receipt for every contribution, and request an appraisal early for high-value property. If you receive goods or services, confirm the written disclosure and use the net deductible amount. By aligning your records with the IRS donation value rules and the 2017 standards, you support an accurate return and a smoother review process if questioned.
Key takeaways
- Fair market value is the standard, not your purchase price or an optimistic estimate.
- Itemize to claim charitable contributions; standard deduction filers cannot.
- Keep written acknowledgements, condition records, and appraisals where required.
- Be aware of AGI percentage caps and carryforward options for excess contributions.
- Account for goods or services received and deduct only the net, excess amount.
Used thoughtfully, these rules help you support causes you care about while maintaining clean, compliant records. Review your donations each year, match values to documentation, and adjust timing and asset choice where it makes sense. This ongoing approach reduces last-minute uncertainty and supports confident, accurate filing.
