Is tax-loss harvesting worth it for substantial capital losses?
I've been pretty terrible at tax planning (and financial planning in general) over the past few years but I'm trying to get better. My capital gains and losses have had some wild swings and I'm in a weird situation now. Looking for advice on the best path forward. Here's my capital gains/losses history: 2020: $54k gain 2021: $50k gain 2022: $267k gain 2023: (-$210k) loss 2024: Realized losses of (-$29k) and unrealized profits of about $113k accumulated over several years The standard advice seems to be to carry forward capital losses, but with a carryover of around $207k in losses, it would take me like 69 years to use them all up at the $3k annual limit. I'm thinking about selling $29k of my unrealized gains this year so I can maintain the carryover loss limit to just (-$3k). Is this approach smart or is there a better strategy for handling this situation? Thanks for any suggestions!

Your thinking is on the right track! Tax-loss harvesting is typically used to offset gains, but you're in an unusual situation with substantial carryover losses. Since you have such a large loss carryover (~$207k), and you can only use $3k against ordinary income per year, it makes sense to realize some of your unrealized gains. By selling investments with $29k in gains, you'd offset those gains completely with your carryover losses, effectively taking profits without any tax consequences. This approach has several benefits: 1) You lock in some profits tax-free, 2) You can reinvest in the same asset class (but not identical securities due to wash sale rules), potentially at a higher cost basis, and 3) You're utilizing your losses more efficiently than the $3k/year limit.

•Thanks for the reply! What about the potential downsides to this approach? Would I be giving up any future tax benefits by using up my losses now instead of carrying them forward? Also, how do wash sale rules apply when you're selling at a gain rather than a loss?

•There aren't many downsides to using your losses against gains - that's exactly what they're intended for. The $3k limit only applies to offsetting ordinary income. You can use unlimited capital losses to offset capital gains. Since your losses would take decades to use up at $3k/year, accelerating their use is generally advantageous. Wash sale rules only apply when selling at a loss, not a gain. If you're selling investments at a gain, you can repurchase the same securities immediately without any wash sale concerns. This gives you flexibility to realize gains while maintaining your investment positions if desired.

After reading your situation, I wanted to share something that helped me with a similar (though not as extreme) situation last year. I discovered this service called taxr.ai (https://taxr.ai) that helped me analyze my complex capital gains situation. I had about $45k in carry-forward losses and wasn't sure how to optimize them. The tool analyzed my full investment history and recommended a specific harvesting strategy that maximized my tax benefits. It identified specific lots I should sell and when, saving me from spreadsheet hell trying to figure it all out myself. Their tax loss harvesting calculator was particularly helpful for my situation.

•Does it work with cryptocurrency losses too? I've got a pile of those from 2022 and no idea how to optimize them against my stock gains.

•I'm curious - how does it compare to what my brokerage already offers? Fidelity has some tax lot optimization tools, but they seem pretty basic. Does taxr.ai actually tell you which specific investments to sell and when, or is it more general advice?

•Yes, it definitely works with cryptocurrency losses. It can analyze your complete portfolio including stocks, ETFs, mutual funds, and crypto. It actually helped me optimize some of my bitcoin losses against gains in my stock portfolio. It goes way beyond what brokerages offer. While Fidelity and others have basic tax lot selection, taxr.ai looks at your entire investment picture across accounts and makes specific recommendations about which lots to sell and when. It's much more sophisticated than the basic "sell highest cost basis first" advice brokerages typically offer. It created a multi-year optimization strategy for me rather than just focusing on the current tax year.

I was skeptical about taxr.ai at first since I've used tax software for years, but I decided to try it after posting about my situation similar to yours. I had about $80k in carry-forward losses from some terrible crypto investments in 2022. The difference was night and day compared to what I was doing before. It showed me I could realize about $30k in gains each year for the next 2-3 years completely tax-free while maintaining my investment strategy. The specific lot recommendations and timing strategies were incredibly detailed - way beyond what TurboTax or my brokerage offered. I've already realized about $25k in gains this year with zero tax impact. For someone with your level of carryover losses ($207k!), I imagine the optimization opportunities would be even greater. Definitely worth checking out.

This reminds me of when I was trying to get clarification on a similar tax situation involving capital loss carryovers. I spent WEEKS trying to get through to the IRS. Busy signals, disconnects, being on hold for hours just to get transferred and disconnected again. I finally found this service called Claimyr (https://claimyr.com) that got me through to an actual IRS agent in under 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent confirmed I could use my carryover losses strategically against future gains without time limit (they don't expire), and clarified some questions I had about wash sales when tax gain harvesting. Saved me from making some costly assumptions about how to handle my losses.

•Wait, how does this actually work? Does it somehow bypass the IRS phone system? Seems too good to be true - I've literally spent hours trying to get through.

•Sorry but this sounds like BS. Nothing can get you through the IRS phone lines. I've tried calling at all hours of the day, different days of the week. There's no "hack" that can bypass millions of people trying to call them. If this worked, everyone would use it and it would stop working.

•It doesn't bypass the system - it automates the calling process. Basically, it uses technology to continuously call the IRS for you and navigates the phone tree automatically. When it finally gets through to an agent, it calls YOUR phone and connects you. So instead of you personally redialing and waiting on hold for hours, their system does the work. I was skeptical too! I thought it sounded impossible, but it actually worked. I'm not saying it's instantaneous - it took about 17 minutes for me - but that's versus the 3+ hours I spent trying on my own without ever reaching anyone. The IRS has even stated they're answering less than 20% of calls, so having a system continuously try for you makes a huge difference.

I need to admit I was completely wrong about Claimyr. After my skeptical comment, I actually tried it out of desperation. I've been trying to understand how my carryover losses from crypto would affect my tax situation for MONTHS. The service connected me to an IRS representative in about 25 minutes. The agent walked me through exactly how to report my large carryover losses and confirmed I could strategically realize gains to use them up faster. She also explained some subtleties about wash sale rules I had misunderstood. I've spent so many hours trying to get through on my own with zero success. This saved me from making a costly mistake on my taxes. For anyone with complex tax questions like this capital loss situation, it's absolutely worth it to speak directly with the IRS rather than guess.

Have you considered working with a CPA? With losses that large and a complex tax situation, it might be worth paying for professional help rather than trying to figure it out yourself or relying on forum advice. I was in a somewhat similar situation (though with smaller numbers) and my CPA helped me develop a multi-year strategy to optimize my losses. He also found some deductions I'd missed in previous years and we filed amended returns.

•I've thought about it but wasn't sure if my situation warranted a CPA. Would you mind sharing roughly what you paid for that service? And did they help specifically with tax-loss harvesting strategies or more general tax planning?

•I paid around $350 for the initial consultation and tax plan development, and then about $400 for each year's tax return preparation. Considering he saved me over $8,000 in taxes through better loss harvesting strategies and finding missed deductions, it was absolutely worth it. He specifically helped with creating a tax-loss harvesting strategy across multiple years, identifying which specific investments to sell when, and properly documenting everything for the IRS. He also advised on how to structure my investments going forward to be more tax-efficient. For someone with $207k in losses like you have, the potential tax savings would likely be much higher than what I experienced.

Just wondering - what investment led to such a massive loss in 2023? Was it concentrated in a single position or spread across multiple investments? Understanding what caused the loss might help with planning how to avoid similar situations in the future while you work on using up the tax loss.

•Not OP, but I'm guessing crypto or maybe options trading. Those are usually the culprits when you see wild swings like $267k gain followed by $210k loss. Regular stock investing rarely produces that kind of volatility unless you're heavily concentrated in a few speculative stocks.

•It was a combination of factors. I had a concentrated position in a few tech stocks that did extremely well in 2022, and I got overconfident. In 2023, I started trading options with larger positions than I should have, and then doubled down when things started going south. I also had some crypto that crashed. The perfect storm basically. I've definitely learned my lesson about diversification and position sizing. I'm working with much smaller position sizes now and have moved a significant portion of my portfolio to index funds. Still have some individual stocks but with strict limits on how much I allocate to any single position.
