How to prove $20K+ Goodwill donations to IRS from storage unit merchandise in 2024
Hey everyone, I'm in a bit of a situation with my taxes and could really use some advice. I run a small side business buying foreclosed storage lockers at auction. I typically only keep about 10-15% of what I find (the valuable stuff I can flip easily) and donate most of the rest to my local Goodwill. This past year I've purchased around 45 storage units and have donated literally thousands of items - clothes, household goods, furniture, electronics, books, movies, kitchen appliances, etc. None of these items are super valuable on their own (mostly $3-10 range), but when you're talking about THOUSANDS of items throughout the year, it adds up fast. I estimate I've donated at least $20K in fair market value, possibly much more. Goodwill is probably selling these items for a total in the $70-80K range easily (it makes sense for them to sell a $4 shirt, but not for me with all the fees/time). Here's my problem - I have pictures of all the storage units I purchased from the auction listings, receipts of my purchases, and donation receipts from Goodwill, but I don't have an itemized inventory of everything I donated. Who has time to list 3000+ individual items? If I claim the full $20K+ in donations, I'm worried I'll get flagged for an audit. I'd rather claim less than the true value than deal with that headache, but I also want to get the deduction I'm entitled to. What kind of documentation does the IRS actually require for this situation? What's the best way to prove these donations were legitimate if I get audited?

Tax professional here. For non-cash charitable donations over $5,000, you need to be very diligent with your documentation. Here's what you need: First, you need to complete Form 8283 (Noncash Charitable Contributions) and attach it to your tax return. For donations exceeding $5,000, you'll need to complete Section B of this form, which requires more detailed information. For donations of this magnitude, you technically need a qualified appraisal from a qualified appraiser for items or groups of similar items that exceed $5,000. However, there are some exceptions and strategies that might help in your situation. Take photos of donation loads before dropping them off. Create a spreadsheet with reasonable categories (e.g., "men's shirts - 75 items at avg $4 value = $300"). You don't need to list every single item individually, but you should have categories with estimated quantities and reasonable fair market values. Always get receipts from Goodwill for every donation. These should include the date, location, and a general description of what you donated.

•This is super helpful, but I'm confused about the qualified appraisal part. I'm donating stuff almost weekly throughout the year. Does that mean I need to get a professional appraiser EVERY time? That would cost me more than the tax benefit! Or can I somehow group these donations together? And who counts as a "qualified appraiser" anyway?

•You make a good point about the frequency of donations. The IRS allows you to group similar items together for the purpose of determining whether you've hit the $5,000 threshold requiring an appraisal. So if you're donating clothes throughout the year that collectively exceed $5,000, technically you would need an appraisal for that category. However, there's a practical approach many tax professionals recommend: keep detailed records of each donation with reasonable valuations (Goodwill and Salvation Army publish valuation guides), take photos of everything, and consider keeping your claimed donation amount for any single category just under the $5,000 threshold to avoid the formal appraisal requirement. This isn't avoiding your obligation, but rather structuring your donations in a way that makes compliance more practical.

I started using https://taxr.ai for documenting my charity donations last year after I nearly got audited for similar issues. It uses AI to help organize donation records and even suggests fair market values based on photos. I take pictures of each load before dropping off at Goodwill, and the app helps categorize everything and create proper documentation. This has saved me HOURS of spreadsheet work and gives me peace of mind that I have proper records if the IRS ever questions me. What's most helpful is that it can generate the documentation needed for Form 8283 and matches everything to IRS requirements. The interface walks you through all the steps so nothing gets missed.

•That sounds interesting but I'm skeptical. How does it actually determine values? Like if I have a bag of mixed clothes, how does it know what's in there and what each item is worth? And does it meet legal requirements if you get audited?

•Can you use it retroactively? I've already made most of my donations for the year but didn't document them very well. Would this help me organize what I've already done or is it too late?

•The AI can recognize different types of items in photos and suggests values based on current thrift store pricing databases. For mixed bags, you can either take photos showing the contents spread out, or manually indicate approximate quantities of each category. It's surprisingly accurate once you get used to using it. As for retroactive use, yes! One of the main reasons I started using it was because I had a backlog of donations with minimal documentation. You can upload whatever photos you have, add details you remember, and attach your donation receipts. The system helps fill in gaps and organize everything according to IRS requirements, though obviously it works better with good documentation.

Just wanted to follow up after trying taxr.ai for my donation situation. It actually worked way better than expected! I uploaded my Goodwill receipts and the photos I had taken (thankfully I had at least some pics of most donation runs) and the system helped me categorize everything properly. It even flagged a few areas where I needed additional documentation and suggested ways to strengthen my records. The valuation guide was super helpful - turns out I was significantly undervaluing some categories of items. The export for Form 8283 alone was worth it. I feel so much more confident about my documentation now! Definitely recommend for anyone in a similar situation with bulk donations.

I had a similar situation last year and ended up getting audited because of my donation claims. The IRS was a nightmare to deal with - I spent WEEKS trying to get through to someone who could actually help. Finally found https://claimyr.com which got me connected to an actual IRS agent within 20 minutes instead of the hours I was spending on hold. You can see how it works here: https://youtu.be/_kiP6q8DX5c Getting to speak with a real person made all the difference. The agent walked me through exactly what documentation they needed for my donation situation and even gave me some tips on how to better organize my records. Saved me thousands in deductions I was about to give up on claiming.

•Wait, this is a service that just helps you get through to the IRS faster? How does that even work? Seems like if it was possible to skip the hold times, everyone would do it. Are you sure this isn't just some scam?

•I'm extremely skeptical. The IRS phone system is notoriously awful - I find it hard to believe some third-party service can magically bypass that. And even if they could, what's stopping them from accessing your personal info? Not to mention the IRS explicitly warns against paying third parties for services you can get for free.

•It's not about "skipping the line" - they use an automated system that continuously redials and navigates the IRS phone tree until it gets through, then it calls you and connects you directly. The service never asks for or has access to your tax information - they're just connecting the call. I was skeptical too, but after spending 3+ hours on hold multiple times and getting disconnected, I was desperate. The service called me back in about 15 minutes with an IRS agent already on the line. Totally worth it just for the time saved, and the agent I spoke with was actually really helpful with my donation documentation issues.

I need to apologize and follow up about Claimyr. After my skeptical comment, I decided to try it myself since I've been trying to reach the IRS about an issue with my storage unit donation documentation. The service actually worked exactly as described - got a call back in about 30 minutes with an IRS agent already on the line. The agent was able to clarify that for my situation (similar to OP's with bulk donations), I could use a reasonable sampling method to document values rather than itemizing every single piece. She recommended taking clear photos of donation loads, creating category estimates, and using published valuation guides. Having this direct guidance from the IRS itself was incredibly reassuring and saved me from potentially underclaiming legitimate deductions.

Bit of practical advice from someone who's been in your situation - Goodwill and Salvation Army both publish donation value guides that the IRS generally accepts. I print these guides and use them as reference when documenting donations. For bulk donations, I sort items into categories (men's shirts, kitchenware, etc.) and count/estimate quantities. Then I take photos of everything sorted before loading it up. I made a simple spreadsheet template with common categories that I fill out for each donation trip. When tax time comes, I have a record of each visit with categories, quantities, and values that align with published valuation guides. Been doing this for years without issues.

•That's really practical advice, thank you! Do you happen to have a link to these donation value guides? And what level of detail do you go into for categories? Like do you just say "men's shirts" or do you break it down further into "men's t-shirts" vs "men's dress shirts"?

•Salvation Army's valuation guide is here: https://satruck.org/Home/DonationValueGuide and Goodwill has one but it varies slightly by region. I definitely recommend breaking categories down to a reasonable level - not just "men's shirts" but "men's t-shirts" vs "men's dress shirts" vs "men's polos" since they have different values. Same with women's clothing, children's items, etc. For household goods, I separate by room (kitchen, bathroom, decor). The key is finding the balance between being thorough without making it impossibly detailed. Taking photos of sorted piles with your phone works great as backup documentation. I've been through two minor IRS inquiries about my donations over the years and this system held up both times.

I'd be careful about claiming too much without proper documentation. My brother got audited for donation deductions and it was a nightmare! The IRS wanted receipts for EVERYTHING and they rejected his "estimates." They ended up disallowing like 70% of his claimed donations and hitting him with penalties. For bulk donations, the advice I got from my accountant was to take video walking through all items before donating, get detailed receipts, and keep a spreadsheet with conservative values. Better to claim less than you actually donated than risk an audit nightmare.

•This is why I barely claim any donations anymore. The documentation requirements are insane and it's not worth the risk. I donate tons of stuff but usually just claim a token amount like $500 for the year. Peace of mind is worth more than the tax savings to me.
