How to write off different types of investment losses on taxes - angel investment, startup equity, and stock losses
I've had a pretty rough year with investments and need to figure out the tax implications for my 2025 filing. I've got three different scenarios I'm trying to understand: 1. Back in 2020, I put $150,000 into a startup as an angel investor ($100,000 cash plus $50,000 worth of consulting work that was converted to equity). They just went under this year, so that investment is completely worthless now. 2. At another startup in 2020, I agreed to defer about $60,000 of my salary for stock options. I was working there full-time when I made this arrangement. The company folded in 2022, making those options worthless. All I have to document this is some emails and paystubs showing the reduced salary - nothing super official. 3. I've got about $22,000 in unrealized losses in my stock portfolio (long-term capital losses). I'm in the 24% tax bracket currently. From what I understand, the angel investment might qualify as an ordinary income loss, but I'm not sure how to claim it. I also know I can write off $3,000 per year against long-term capital gains, but I'm confused about the deferred salary situation. My questions are: 1. How should I handle the angel investment loss on my 2025 taxes? 2. Is there a limit to how much I can write off for ordinary income loss, or can I claim the full amount? 3. What options do I have for the deferred salary that turned into worthless options? 4. Would there be any tax benefit to selling my underperforming stocks this year? I'm planning to hire a CPA for my 2025 taxes since this is all pretty complex, but I want to understand my options before our meeting. Thanks for any guidance you can provide!

Your investment losses fall under different tax treatments, so let me break them down for you in simple terms: For your angel investment, this might qualify for Section 1244 stock treatment if the company met certain requirements. If it qualifies, you could deduct up to $50,000 ($100,000 if married filing jointly) as an ordinary loss, with the remainder as capital loss. If it doesn't qualify for 1244 treatment, it would be treated as a capital loss. For the deferred salary converted to worthless options, this is trickier. Since you have emails and paystubs, you might be able to claim this as either a capital loss or possibly a business bad debt, depending on the specific circumstances and documentation. For your unrealized stock losses, remember they're only "paper losses" until you actually sell. The $3,000 capital loss limitation against ordinary income only applies after you've realized the loss by selling.

•Thanks for the detailed explanation. I've never heard of Section 1244 before. How do I know if my angel investment qualifies? The startup was a small software company with fewer than 10 employees if that matters. Also, for the deferred salary situation, would claiming it as a business bad debt be more advantageous than a capital loss?

•For Section 1244 qualification, the company needed to be a domestic small business corporation where the total money received for stock didn't exceed $1 million. The company should have derived more than 50% of its income from operations (not investments). You'd need to check if they issued you qualified small business stock documentation. Business bad debt would be more advantageous since it's deductible as an ordinary loss without the $3,000 annual limitation. However, it's harder to qualify for - you'd need to prove there was a valid debt (not just equity) that became worthless. The emails and paystubs help, but a written agreement would have been better. A good CPA can help determine which approach has the strongest support based on your specific documentation.

After spending hours trying to figure out my own investment losses last year, I found this amazing tool called taxr.ai (https://taxr.ai) that really helped me sort through similar issues. I had a situation with some failed investments in a friend's business and wasn't sure how to categorize the losses. The tool analyzed my situation and gave me clear guidance on which IRS forms I needed and how to properly document everything. It even pointed out that I could qualify for some special tax treatment I had no idea about. Saved me a ton of research time and probably thousands in deductions I would have missed.

•Does this actually work for complex investment loss situations? I've got some worthless securities from a tech startup that failed and my tax software doesn't seem to handle it well. Can it tell me specifically which forms to use for claiming these types of losses?

•I'm skeptical about these tax tools. How does it handle the documentation requirements? My concern with investment losses is always proving to the IRS that the investment actually became completely worthless. Does it give guidance on what documentation you need to keep?

•It absolutely works for complex investment situations like worthless securities. It specifically guided me on using Form 8949 for reporting my losses and explained how to code them correctly. It also showed me how to attach a statement explaining the worthless security claim, which my regular tax software never mentioned. For documentation requirements, that's actually where it really shines. It gives you a detailed checklist of exactly what you need to prove your case to the IRS - things like company bankruptcy filings, final stockholder communications, or evidence the company ceased operations. It saved me from an almost certain audit by making sure I had everything properly documented before filing.

I wanted to follow up about my experience with taxr.ai that someone recommended here. I was really confused about how to handle my startup investment losses, but this tool completely simplified the process for me. It walked me through determining if my losses qualified for Section 1244 treatment (which they did!) and gave me step-by-step instructions for the documentation I needed. The tool even generated a detailed statement explaining my worthless securities that I could attach to my return. My CPA was impressed with how organized everything was, and we were able to claim a much larger deduction than I initially thought possible. Definitely worth checking out if you're dealing with investment losses.

If you're trying to contact the IRS to get clarification on these investment loss rules, good luck. I spent 3 weeks trying to get through to someone who could actually answer questions about Section 1244 and worthless securities. After hours on hold, I finally discovered Claimyr (https://claimyr.com) and watched their demo at https://youtu.be/_kiP6q8DX5c. They got me connected to an actual IRS agent in about 20 minutes who was knowledgeable about investment loss rules. The agent cleared up my confusion about documenting when my investments officially became worthless and gave me specific guidance on how to report everything correctly. Saved me from making some pretty big mistakes on my return.

•How does this actually work? I thought the IRS phone system was completely broken. Are they just auto-dialing constantly or something? Seems too good to be true.

•This sounds like snake oil to me. I've tried everything to get through to the IRS including calling at weird hours. There's no way some service can magically get you through when millions of others can't. What's the catch?

•It works by using a system that navigates the IRS phone tree automatically and holds your place in line. When it reaches an actual person, you get a call connecting you directly to that agent. No more listening to hold music for hours. There's no catch - they just solved a really frustrating problem with technology. I was skeptical too until I tried it. The difference is they're monitoring multiple lines simultaneously and can connect you when one opens up. I've now used it twice - once for the investment questions and once for a notice I received. Both times I got through to someone who could actually help within about 15-20 minutes.

I need to eat my words about Claimyr. After my skeptical comment, I decided to try it when I needed to ask about the documentation requirements for claiming worthless securities from my angel investments. I was fully prepared to come back here and call it a scam. Instead, I got connected to an IRS tax law specialist in about 15 minutes who walked me through exactly what I needed to substantiate my worthless investment claims. They confirmed I could take an ordinary loss under Section 165(g)(3) since I owned more than 80% of the startup's stock. This was completely different from what my tax software was telling me to do! Saved me from a major error that would have cost thousands. I'm impressed.

Something important that hasn't been mentioned yet: timing is critical for claiming worthless securities. You need to be able to identify the specific tax year when the investment became completely worthless. For your angel investment that folded in 2024, you should claim it on your 2024 return (which you'll file in 2025). If you wait until 2025 to claim it, the IRS could disallow the deduction saying it became worthless in 2024. Also, for your stock losses, you might want to consider tax-loss harvesting before year-end to offset any capital gains you might have.

•Thanks for bringing up that point about timing. What kind of documentation would I need to prove the exact year my angel investment became worthless? The company slowly declined throughout 2023 but officially closed in early 2024. Also, I don't have many capital gains this year, but I might next year - would it make sense to carry over the losses?

•For documenting the year of worthlessness, you'll want to gather things like the company's bankruptcy filing, dissolution documents filed with the state, a final letter to investors announcing closure, or evidence that assets were liquidated. The key is showing the investment had value at the end of 2023 but became worthless in 2024. Regarding carrying over losses, that's a good strategy. If you don't have significant capital gains this year, you can use up to $3,000 against ordinary income, and then carry forward the remaining capital losses indefinitely to future years. If you expect larger capital gains next year, having those carryover losses available could be very beneficial. Just make sure you're keeping careful records of your loss carryovers.

Has anyone had experience with the deferred salary situation specifically? I had something similar happen where I took stock instead of salary, and when the company went under, the IRS initially questioned my write-off. I had to fight to prove it wasn't just a capital loss.

•I had a similar situation. What worked for me was filing it as a business bad debt on Form 8949 with code G, and attaching a detailed statement explaining the arrangement. I included emails from the CEO confirming the salary deferral arrangement and proof the company was dissolved. The key was showing it was actually compensation I was owed, not just an investment that went bad.

One thing to keep in mind with your angel investment is that you might also want to look into whether it qualifies as Qualified Small Business Stock (QSBS) under Section 1202. Even though the investment became worthless, if it was QSBS when you acquired it, you could potentially get better tax treatment on any gains from other QSBS investments by increasing your exclusion amount. Also, regarding your $22,000 in unrealized stock losses - if you're planning to hold onto those stocks long-term, consider whether tax-loss harvesting makes sense. You could sell the losing positions before year-end to realize the losses, then use them to offset any capital gains plus up to $3,000 against ordinary income. Just be careful about the wash-sale rule if you want to buy back similar positions within 30 days. The timing advice from Amara is spot-on. Since you're already planning to work with a CPA, make sure to gather all your documentation now - startup dissolution papers, final investor communications, employment agreements showing the salary deferral arrangement, etc. Having everything organized will make your CPA consultation much more productive and potentially save you money on their fees.

•This is really helpful advice about QSBS - I hadn't considered that angle at all. Even though my angel investment is now worthless, it's good to know it might still have future tax benefits if I make other QSBS investments. One question about the wash-sale rule you mentioned: if I sell my losing stocks to harvest the losses, how similar do the replacement stocks need to be to trigger the wash-sale rule? For example, if I sell individual tech stocks at a loss, could I immediately buy a tech sector ETF instead, or would that still be considered "substantially identical"? Also, regarding documentation - should I be requesting specific paperwork from the failed startups, or is it too late for that? I have some emails and investor updates, but I'm wondering if there are official dissolution documents I should try to track down from the state business registry.
