Form 8283 – Noncash Charitable Contributions Guide 2025

I still remember the first time a client’s deduction was flagged over a missing signature on Section B. Everything else was perfect, but the appraiser hadn’t signed Part IV, and the return stalled until we fixed it.

If you have ever donated stock, art, a vehicle, or even a big haul of household goods, you know the sinking feeling of wondering whether you filed Form 8283 correctly. The good news, you can make this smooth, predictable, and audit‑ready with a little structure.

Think of Form 8283 as your proof of value, timing, and support for noncash gifts. When it is complete and consistent, reviews move faster and deductions hold up.

This guide walks you through what the IRS expects in 2025, how to pick the right section, what to keep in your records, and the common tripwires that cause denials. Where helpful, I add quick examples and checklists you can reuse with clients or your internal team.

Note: This article is general information as of December 9, 2025. Always review the latest IRS instructions and consider your facts before filing.

Key takeaways

• Use Form 8283 when your total noncash charitable deductions exceed 500 for the year. Individuals, partnerships, S corporations, and most corporations file, with special C‑corp thresholds noted below.
• Use Section A for items of 5,000 or less, for publicly traded securities, for qualified vehicles when your deduction is limited to gross proceeds, and for certain other exceptions.
• Use Section B for any single item or group of similar items over 5,000, and get a qualified appraisal plus appraiser and donee signatures. Attach the appraisal if the total claimed value for an item exceeds 500,000.
• Vehicle donations generally follow the charity’s Form 1098‑C and, if sold without significant use or improvement, your deduction is capped at the charity’s gross sale proceeds.
• Keep contemporaneous acknowledgments, basis, and valuation support. The IRS closely reviews noncash deductions and requires precise completion of the correct section.

What Form 8283 is, and when you must file it

Form 8283 reports your noncash charitable contributions and the details that support your deduction, including what you gave, when you acquired it, your cost or basis, your valuation method, and the charity’s information. If your total noncash contributions exceed 500, the form must be attached to your return. Failure to fully complete the right section, or to obtain required signatures or a qualified appraisal when needed, can lead to disallowance.

Who files

• Individuals, partnerships, S corporations, and corporations generally file Form 8283 when a single item or a group of similar items exceeds the 500 threshold.
• C corporations that are not personal service or closely held generally only file when a single item, or similar group, exceeds 5,000. Personal service corporations and closely held C corps must file at over 500.

What counts as a “similar group”

Similar items of property are items of the same general type, such as clothing, books, or paintings. To determine whether you cross the 5,000 threshold for Section B, you must aggregate similar items, even if donated to more than one charity. If the aggregate exceeds 5,000, you complete a separate Section B for each donee.

Quick chooser, Section A vs Section B

Item or situation	Section you complete	Special requirements
Publicly traded stock or mutual fund shares	Section A	No qualified appraisal required; value typically uses the average of the high and low on the contribution date.
Qualified vehicle where deduction is limited to charity’s sale proceeds	Section A	Attach Form 1098‑C or the acknowledgment showing gross proceeds.
Any single item or similar group over 5,000, most property types	Section B	Qualified appraisal, appraiser signs Part IV, donee signs Part V.
Nonpublicly traded securities over 5,000	Section B	Qualified appraisal required.
Total deduction for an item over 500,000	Section B	Attach the qualified appraisal to your return.

Why accuracy matters in 2025

Two regulation sections drive most of the compliance burden. Section 1.170A‑16 sets the substantiation and reporting rules for thresholds at 250, 500, 5,000, and 500,000, including when to use Section A versus Section B. Section 1.170A‑17 defines what a “qualified appraisal” is, who counts as a “qualified appraiser,” what must be in the report, and the 60‑day timing window. If you miss one of these elements, your deduction can be denied even when the gift was real and generous.

A quick practice tip, track appraiser and donee signatures early, not at filing time, and pin each to the specific property ID you will reference on Section B. This saves last minute chasing and prevents mismatched descriptions.

Section A vs Section B, how to pick the right path

When your total noncash gifts exceed 500, you must attach Form 8283. The section depends on the property and value.

• Section A is for property of 5,000 or less, publicly traded securities regardless of value, qualified vehicles when the deduction is limited to the charity’s sale proceeds, and a few other exceptions.
• Section B is for any single item, or similar group, with a deduction over 5,000. You will need a qualified appraisal, the appraiser’s declaration in Part IV, and the charity’s acknowledgment in Part V.

If your team donates multiple lots of similar items to different charities, aggregate them to test the 5,000 threshold, then prepare a separate Section B for each donee that received part of that group.

Appraisal exceptions you can rely on

You do not need a qualified appraisal for the following, even when the total exceeds 5,000, provided you complete the appropriate section correctly.

• Publicly traded securities, as defined in the regulations.
• Certain intellectual property.
• Qualified vehicles with the proper acknowledgment when the deduction is capped by sale proceeds.
• Inventory or property held primarily for sale to customers.

What makes an appraisal “qualified”

Your appraisal must be signed and dated by a qualified appraiser no earlier than 60 days before the date of the contribution and no later than the return due date for the year you first claim the deduction. It must follow generally accepted appraisal standards, list the valuation method and specific basis for value, and include the appraiser’s qualifications. Keep the appraisal with your records, and attach it to the return if you claim more than 500,000 for any one item.

Valuation basics that hold up under review

The baseline is fair market value, the price a willing buyer and willing seller would agree to on the date of the gift, both with reasonable knowledge of the facts. The IRS expects objective evidence that fits the asset type.

• Publicly traded securities, use the average of the high and low on the contribution date, or the weighted average around the date if no trades occurred that day.
• Vehicles, use the charity’s 1098‑C for gross proceeds if sold, or acceptable pricing guides adjusted to condition when another exception applies.
• For large or unique items, a qualified appraisal explains the method, the comps, and the reasoning, and it ties to your Section B detail.

Basis still matters

Your adjusted basis can limit the deduction, for example, short‑term or ordinary income property usually limits your deduction to basis, not FMV. Publication 526 explains the ordering and limits that may apply alongside Form 8283.

Special rule, vehicles and Form 1098‑C

If the charity sells the vehicle without significant intervening use or material improvement, your deduction is generally limited to the charity’s gross sale proceeds. The charity must give you a contemporaneous written acknowledgment, typically on Form 1098‑C, within 30 days of the sale or receipt, and you attach it to your return. There are exceptions when the charity significantly uses or improves the vehicle, or transfers it to a needy individual at a price significantly below FMV to further its charitable purpose. In those exceptions, FMV may be allowed.

Quick example, you donate a car and the charity later sells it for 7,000. With no significant use or improvement documented, your deduction is generally 7,000, not a higher guide value.

Records the IRS expects you to keep

• Contemporaneous written acknowledgments for gifts of 250 or more.
• Basis and acquisition details, including when and how acquired.
• Qualified appraisals when required, with appraiser and donee signatures captured for Section B.
• For stock, keep brokerage confirmations showing transfer date, and the pricing used to compute FMV.

A small investment in file hygiene saves time in review. If you run a firm, standardize filenames, versions, and checklists so reviewers see the same structure every time.

AGI limits and five‑year carryforwards

Form 8283 reports the gift, but your deduction still must pass the percentage‑of‑AGI limits and ordering rules in Publication 526. In general, cash gifts to public charities are limited to 60% of AGI, and noncash gifts often fall into 50%, 30%, or 20% categories depending on the property and the donee. If your allowed deduction is less than the value you reported, the remainder may carry forward up to five years, and the substantiation rules still apply in the carryforward years.

Fast framework to apply limits

• Classify the property, cash, ordinary income property, or long‑term capital gain property.
• Identify the donee type, for example, public charity or private foundation.
• Apply the correct AGI percentage limit and ordering rules.
• Track any unused amount as a carryforward, then reapply the same rules next year, oldest carryforward first.

Step‑by‑step, completing Form 8283

• Confirm you must file. If your total noncash gifts exceed 500, you must attach Form 8283.
• Choose the section.
• Section A for items of 5,000 or less, publicly traded securities, qualified vehicles with sale‑proceeds limits, and specified exceptions.
• Section B for items, or similar groups, over 5,000.
• Gather data. Description, date acquired, how acquired, basis, donation date, valuation method, and FMV. For stock, capture the average of the day’s high and low.
• If Section B applies, secure a qualified appraisal, have the appraiser sign Part IV, and have the donee sign Part V.
• Check thresholds. If a single item deduction exceeds 500,000, attach the appraisal to your return.
• Attach Form 8283 to your return and retain all support, including acknowledgments and appraisals, for your records.

Mini‑checklist you can paste into your workpapers

• Similar items aggregated and tested against the 5,000 threshold.
• For vehicles, 1098‑C attached or equivalent acknowledgment included.
• Appraisal dated within 60 days before the gift, signed by a qualified appraiser, with valuation method and comps.
• Section B, Part IV and Part V signatures present and readable.
• If deduction for an item exceeds 500,000, appraisal attached to return.

Practical examples

• Example, publicly traded stock. You donate 1,000 shares on March 15. The day’s high is 52 and the low is 50, so the FMV per share is 51, and you report the gift in Section A. Keep the broker transfer slip and the price computation.
• Example, vintage guitar worth 7,500. You aggregate similar guitars donated this year and exceed 5,000, so you complete Section B, get a qualified appraisal signed within the timing window, obtain the charity’s Part V signature, and attach the form.
• Example, vehicle sold by the charity. The charity sells within weeks for 4,200, sends you Form 1098‑C, and your deduction is generally limited to 4,200.

Reviewer note you can add to your file: “Section chosen, signatures verified, valuation evidence attached, AGI limit modeled, carryforward tracked if applicable.”

Common mistakes that lead to denials

• Filing Section A instead of Section B after aggregating similar items above 5,000.
• Missing appraiser signature or outdated appraisal outside the 60‑day window.
• Forgetting to attach the appraisal when the claimed deduction for an item exceeds 500,000.
• Relying on retail dealer prices for vehicles rather than the charity’s sale proceeds when applicable.

FAQs, quick answers

Who must file Form 8283?

You must attach Form 8283 if your total noncash charitable contributions exceed 500 for the year. Individuals, partnerships, S corporations, and corporations file, with special thresholds for certain C corporations.

Do publicly traded securities need an appraisal?

No. Publicly traded securities are an appraisal exception. Report them in Section A and generally use the average of the day’s high and low to compute FMV.

When is a qualified appraisal required?

For most noncash gifts where a single item or similar group exceeds 5,000, you must obtain a qualified appraisal, have the appraiser sign Part IV, and the donee sign Part V. The appraisal must be dated within the 60‑day window.

What about vehicles?

If the charity sells the vehicle without significant use or improvement, your deduction is generally limited to the gross sale proceeds shown on Form 1098‑C, which you attach to your return. Exceptions allow FMV in limited cases.

How do AGI limits and carryforwards work?

Your deduction is capped by percentage‑of‑AGI limits that depend on property type and the donee. Unused amounts can carry forward for up to five years and are subject to the same limits in each carryforward year.

Editor’s checklist for firms

• Build a standard Section A and Section B packet, including labeled evidence for description, basis, and FMV method.
• Use a signature tracker for Part IV and Part V with reminders tied to the return due date.
• Create a mini‑matrix for AGI limit modeling and carryforward tracking in your tax software file.

If you manage a busy accounting practice, structure and visibility keep reviewers out of endless loops. At Accountably, we integrate disciplined workpaper naming, appraiser‑signature tracking, and deadline accountability into your workflow so Section B files reach review ready, with fewer revision cycles. Use this when you truly need a delivery partner that respects your standards and systems, not a quick staffing patch.
