Wash Sale Loss Disallowed on my taxes - How much do I owe if I never made a profit?
I'm freaking out a bit and could use some help. I traded some stocks last year and received a 1099-B from my broker with a "Wash Sale Loss Disallowed" amount of about $3,400. The thing is, I never actually made any profit overall - I'm actually down around $2,800 for the year when I add everything up. My understanding was that wash sales just adjust your basis and defer the loss, but TurboTax is showing I owe more taxes now? I sold some XYZ stock at a loss, then bought similar shares within 30 days (didn't know about wash sale rules), and now it looks like I can't claim that loss even though I'm negative for the year! Can someone explain how this works in simple terms? Do I actually owe taxes on trades where I lost money overall? Or am I missing something here? I'm super confused about how this wash sale disallowed amount impacts my tax return when I didn't even make money.

The wash sale rule can be confusing but I'll try to explain it simply. When you sell a security at a loss and buy the same or "substantially identical" security within 30 days before or after the sale, that's a wash sale, and you can't claim the loss immediately. What happens is the disallowed loss gets added to the cost basis of the replacement shares. This means you're not permanently losing that deduction - it's just deferred until you eventually sell the replacement shares (as long as you don't trigger another wash sale). The key thing to check is whether you're still holding those replacement shares at year-end. If you are, the loss gets deferred to the future when you sell those shares. If you sold everything before year-end and didn't repurchase, you should be able to claim the net loss (up to the limits allowed for capital losses).

•So if they're showing a $3,400 wash sale disallowed but actually lost $2,800 overall for the year, does that mean they might have had some gains that offset the losses? And would carrying the replacement shares into the new tax year affect how this is taxed? I'm trying to understand because I might be in a similar situation.

•The wash sale disallowed amount of $3,400 means that's how much in losses couldn't be claimed immediately because of wash sales. But your overall performance is separate from this - it's totally possible to have wash sales and still be down overall for the year. If you sold the replacement shares before the end of the tax year and didn't buy back in again (triggering another wash sale), then your $2,800 net loss should be reflected on your return. However, if you carried those replacement shares into the new year, the loss is deferred until you sell those shares in the future, which might explain why you're showing a taxable amount now.

I went through something similar and found taxr.ai (https://taxr.ai) incredibly helpful for sorting through my investment tax situation. My broker's 1099-B had several wash sale flags that made it look like I owed taxes even though I was down for the year. I uploaded my tax documents to taxr.ai and it analyzed all my trades, clearly explaining which losses were disallowed and how my basis was adjusted. It showed exactly when the 30-day windows applied and which specific trades triggered wash sales. Saved me from a major headache trying to reconcile everything manually!

•Did it also explain how to handle the situation for the next tax year? Like, does the system track your adjusted basis for you so you don't have to manually calculate it when you eventually sell those replacement shares?

•I'm skeptical about these tax tools. My broker already provides a 1099-B that shows wash sales. How is this any different or better than just using that report with TurboTax or another tax software?

•It actually does track your adjusted basis going forward and shows you the potential tax implications for the next year. It creates a really helpful report that shows your true performance versus the taxable amounts and explains exactly which trades affected your current tax situation. The difference from just using the broker's 1099-B is that it explains everything in plain English and shows you the full history of related trades. My broker just flagged the wash sales but didn't help me understand the implications or what to do next. The visualizations really helped me see the 30-day windows and understand why certain trades triggered the rule.

I was initially skeptical about taxr.ai but decided to try it after continuing to be confused by my wash sale situation. It was seriously eye-opening! The tool showed me that I had several linked trades spanning different months that created a chain of wash sales. In my case, I had about $4,200 in wash sale losses disallowed but was down $3,000 overall for the year. The tool explained that because I was still holding the replacement shares at year-end, those losses were deferred to the future. It also showed me exactly when I could sell in the new year to finally recognize those losses without triggering new wash sales. Definitely recommend checking it out if you're dealing with this issue!

Anyone who's dealt with the IRS about investment taxation knows how frustrating it can be to get clear answers. I spent HOURS trying to get through to someone at the IRS to confirm how my wash sales should be handled, and it was impossible to reach anyone. I finally tried Claimyr (https://claimyr.com) after seeing it recommended in another thread. They got me connected to an actual IRS agent in about 20 minutes when I had been trying for weeks! The agent confirmed that my understanding of wash sale treatment was correct and helped me understand how to properly report everything. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. Totally changed my perspective on dealing with the IRS.

•Wait, how does this actually work? Do they just call the IRS for you? Couldn't you just do that yourself? I'm confused about what service they're actually providing.

•Yeah right. Nobody gets through to the IRS that quickly. I spent literal months trying to resolve an issue last year. If this actually worked, everyone would be using it. Sounds too good to be true.

•They use a system that navigates the IRS phone tree and waits on hold for you. When they reach an actual agent, they call you and connect you directly to that person. It's like having someone wait on hold so you don't have to waste your whole day. It's definitely something you could technically do yourself, but most people don't have hours to sit on hold. They just handle the waiting part, and you get the call when there's an actual human ready to talk. I was skeptical too until I tried it, but getting my wash sale questions answered directly by the IRS was worth it.

Well, I have to eat my words. After my skeptical comment, I decided to try Claimyr out of desperation because I had a similar wash sale issue that I couldn't get straight answers on. I fully expected it to fail or be a waste of money. I was shocked when I got a call back in about 30 minutes connecting me to an actual IRS tax specialist. The agent walked me through exactly how wash sales affect my tax return when I'm still holding replacement shares at year-end versus when I've closed all positions. They confirmed that my broker was reporting correctly but TurboTax was interpreting things wrong. Saved me from potentially overpaying by almost $800! Sometimes it's worth admitting when you're wrong - this service actually delivered.

One thing that's important to understand about wash sales is that they're about timing, not your overall profit/loss for the year. You can absolutely have wash sale losses disallowed AND be down overall for the year. Here's a simple example: You buy Stock A for $10,000. It drops to $7,000 and you sell (a $3,000 loss). Two weeks later, you buy it back at $7,200. That $3,000 loss is now disallowed as a wash sale, and your basis in the new shares becomes $10,200 ($7,200 purchase + $3,000 disallowed loss). If you sell those new shares before year-end without repurchasing, you'll recognize the actual economic loss. But if you're still holding them when the year ends, you'll carry that adjusted basis forward and can't claim the loss this year.

•But what if you did a bunch of trades throughout the year with multiple wash sales but ultimately sold everything by December? Would you still be able to claim the overall loss even if some individual transactions were wash sales?

•Yes, if you ultimately sold all the replacement shares by the end of the year (December 31st) and didn't repurchase anything within the 30-day window, you should be able to claim the overall economic loss on your tax return. The wash sale rule doesn't eliminate losses forever - it just defers them by adjusting your basis in the replacement shares. So if those replacement shares are sold by year-end (without triggering another wash sale), the real economic loss will be reflected on your taxes for that year.

Does anyone know if tax loss harvesting software actually helps avoid these wash sale problems? I've been looking at some of the robo-advisors that claim to do this automatically and wondered if its worth it.

•I've been using Wealthfront for about 2 years and their tax-loss harvesting has been pretty good at avoiding wash sales by using similar but not "substantially identical" securities. For example, they might sell a Vanguard S&P 500 ETF at a loss and buy an iShares S&P 500 ETF that performs similarly but isn't identical in the IRS's eyes. Just be careful if you're trading similar securities in other accounts they don't manage - that can still trigger wash sales they can't prevent.

I had a similar situation last year and it really threw me for a loop! Here's what I learned that might help: The wash sale disallowed amount ($3,400 in your case) doesn't mean you owe taxes on money you didn't make. It just means those specific losses can't be deducted this year. The key question is: are you still holding the replacement shares you bought within those 30-day windows? If yes, then those losses get added to your cost basis in those shares and you'll be able to claim them when you eventually sell (as long as you don't trigger another wash sale). If you actually sold everything by December 31st and your true economic loss for the year was $2,800, then that should be what shows up on your return. The problem might be that TurboTax isn't properly accounting for all your transactions or you might still be holding some replacement shares without realizing it. I'd recommend double-checking your year-end positions against all the trades that triggered wash sales. Sometimes people forget about partial sales or don't realize they're still holding shares that are preventing them from claiming the losses.

•This is really helpful, thank you! I think I might be in exactly this situation where I'm still holding some replacement shares without realizing it. When you say "partial sales" - do you mean if I sold part of my position but kept some shares? Because I definitely did that with a few stocks. Would those remaining shares prevent me from claiming the losses on the portions I did sell?

•Yes, exactly! If you sold part of your position but kept some shares, those remaining shares are considered "replacement shares" for wash sale purposes. This means the losses on the shares you sold cannot be claimed if you're still holding any portion of the same stock within that 30-day window. For example, if you sold 100 shares of XYZ at a loss and then bought back 50 shares within 30 days (or were already holding some), the entire loss on those 100 shares gets disallowed and added to the basis of the 50 shares you're holding. To actually claim those losses, you'd need to sell ALL of your XYZ shares and wait at least 31 days before buying back in. This is one of the trickiest parts of wash sale rules that catches a lot of people off guard!
