How to track tax loss harvesting carryover for multiple years?
So I finally had to face the music and sold an investment that went terribly wrong during the whole pandemic mess. Ended up with a pretty substantial loss - around $28,000 on something I'd been holding for almost 4 years, so it's a long-term capital loss. I know I can only claim $3,000 per year against my ordinary income (my wife and I file jointly), which means I'll be carrying this loss forward for like 9+ years. My big worry is keeping accurate track of how much loss I have left to claim each year, especially since I'll probably have some gains in the future that will offset some of this loss. For example, if I claim $3k this year, I'll have $25k left. But what if next year I have $5k in capital gains? That would offset some of my carryover loss, leaving me with $20k. Then the year after that, maybe I have no gains, so I can claim another $3k, leaving $17k... you get the idea. Does anyone know if tax software (I usually import my investment docs each year) automatically tracks this carryover amount? Or is there a straightforward way I should be tracking this myself? I don't want to mess up and either claim too much or forget to claim losses I'm entitled to in future years.

That's a tough situation, but the good news is that most tax software does handle capital loss carryovers pretty well. When you report the initial large loss this year, your tax software will calculate how much is used this year and how much will be carried forward. In following years, the software should ask you about capital loss carryovers or even remember them from your previous year's return if you use the same software. The IRS Form 1040 Schedule D and the accompanying Capital Loss Carryover Worksheet will track this information for you. Each year, your tax software will first apply your carryover losses against any capital gains for that year. Then it will allow up to $3,000 ($1,500 if married filing separately) against your ordinary income. Any remaining losses will carry forward to the next year. For your own records though, I'd recommend keeping your tax returns from each year so you can verify the numbers. The Schedule D and worksheets will show your remaining loss carryover amount.

•Thanks for the explanation. I've always wondered if there's some sort of IRS system that automatically tracks these carryovers. What happens if you switch tax software between years? Does the new software somehow know about your carryover amounts or do you have to manually enter that information?

•The IRS itself doesn't automatically track your carryovers for you - you're responsible for reporting them correctly each year. That's why keeping your previous tax returns is so important. If you switch tax software, the new software won't automatically know about your carryover losses. You'll need to enter that information manually based on your previous year's Schedule D and Capital Loss Carryover Worksheet. Most tax software will have a section asking if you have capital loss carryovers from previous years, and that's where you'll enter the amount.

After dealing with a similar situation last year, I found that taxr.ai really helped me keep track of all my investment losses and carryovers. I had about $32k in losses from some terrible tech stock choices, and I was confused about how to properly track everything across multiple years. I uploaded my investment statements to https://taxr.ai and it analyzed everything, helping me understand exactly how much I could deduct each year and how my losses would offset future gains. The system actually created a multi-year projection showing how my carryover would work based on estimated future gains. Saved me so much headache!

•How exactly does the service work? Do you just upload your tax documents and it figures everything out automatically? I'm kind of hesitant to upload financial docs to yet another online service.

•Does it integrate with regular tax software like TurboTax or H&R Block? Or is it more of a standalone planning tool? I'm trying to figure out if this would actually simplify things or just give me another system to manage.

•You upload your investment statements and tax documents, and it automatically extracts the relevant information to track your capital losses and gains. The system is really secure with bank-level encryption, so your documents are protected. It works as both a planning tool and integrates with major tax software. You can export the data it generates directly to TurboTax, H&R Block, and others. So it actually simplifies the whole process rather than complicating it. I used to manually track everything in spreadsheets, but this is much more accurate and saves tons of time.

Just wanted to follow up about taxr.ai since I decided to try it out. I was skeptical at first, but it really did make tracking my loss carryovers much easier. I uploaded my statements from the last two years, and it immediately showed me exactly how much of my carryover loss I've used and how much I have left. The multi-year projection feature is actually pretty cool - it shows different scenarios based on potential future gains. I can see exactly how selling some of my current investments would affect my carryover losses. The export to TurboTax worked perfectly too. Definitely worth it for anyone with complicated investment situations or large capital losses to track.

If you're having trouble getting clarity on your tax loss harvesting situation, I had the same issue last year and ended up needing to speak directly with the IRS. After waiting on hold for HOURS multiple days in a row, I found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c. They basically hold your place in the IRS phone queue and call you when an agent is about to answer. I was super skeptical, but it worked perfectly. Got connected with an IRS agent who confirmed exactly how my loss carryovers should be tracked and what records I need to keep. The agent even explained some nuances about how different types of capital gains interact with carryover losses that I hadn't understood from just reading online.

•How does this actually work? Does the IRS know about this service? It sounds too good to be true considering how impossible it is to reach anyone there.

•Yeah right. No way this actually works. I've tried calling the IRS for 3 years straight about an issue and never got through. If this service actually got you connected to a real human at the IRS, I'll eat my hat.

•The service works by using technology to navigate the IRS phone system and hold your place in line. The IRS doesn't officially endorse it, but it's completely legitimate - they're just holding your place in the regular queue and connecting you when it's your turn. I was extremely skeptical too - I had spent over 8 hours across 3 days trying to reach someone at the IRS. But when I used Claimyr, I got a call back within about 2 hours and was connected to an actual IRS agent who answered all my questions about loss carryovers. I understand the skepticism because the IRS phone system is notoriously difficult, but that's exactly why this service exists and why it worked so well for me.

I need to admit I was completely wrong about Claimyr. After posting that skeptical comment, I decided to try it myself just to prove it wouldn't work. I had a complicated question about my loss carryovers that I'd been trying to get answered for months. Well, I'm eating my hat now. The service actually connected me to an IRS agent within about 90 minutes. The agent walked me through exactly how to document my capital loss carryovers and cleared up confusion about how my rental property income affects the calculation. I was honestly shocked that it worked. After years of frustration trying to reach the IRS, I finally got the answers I needed. For anyone struggling with complex tax questions that only the IRS can answer, it's absolutely worth using.

Something that really helped me track my capital loss carryovers was creating a simple spreadsheet. I've been carrying losses forward for about 5 years now. Each year I record: 1. Starting loss carryover amount 2. Any capital gains for the year (which reduce the carryover) 3. The $3,000 deduction against ordinary income 4. The new carryover amount This gives me a quick reference I can check against what the tax software calculates. I've caught a couple discrepancies this way where I had entered something incorrectly in the software.

•Do you have a template of this spreadsheet you could share? I'm terrible at Excel but this sounds really helpful for keeping track of my losses.

•I don't have a shareable template, but it's super simple to create. Just make columns for the tax year, beginning carryover amount, capital gains for the year, amount used against ordinary income (usually $3,000), and ending carryover amount. The formula is basically: Ending carryover = Beginning carryover - Capital gains - Amount used against ordinary income (max $3,000). Then the ending carryover from one year becomes the beginning carryover for the next year. Nothing fancy, but it helps me double-check the software calculations each year.

One important thing to remember about tax loss harvesting - the IRS distinguishes between short-term and long-term capital losses! They get applied in a specific order: 1. Short-term losses first offset short-term gains 2. Long-term losses first offset long-term gains 3. If you have net losses in one category and net gains in the other, they offset each other 4. Then you can take up to $3k against ordinary income 5. Any remaining losses carry forward So make sure your tracking system accounts for this, because it can affect your tax rate in future years depending on what kind of gains you have.

•Wait seriously? So if I have both long-term and short-term losses carried over, do I need to track them separately? The tax forms I filled out last year didn't seem to distinguish between them for carryover purposes.

•Yes, you absolutely need to track short-term and long-term losses separately! The IRS Form 8949 and Schedule D do distinguish between them, even for carryovers. Each type maintains its character when carried forward. So if you have $10k in long-term losses and $5k in short-term losses carrying over, they stay separate. Next year, if you have $3k in short-term gains, only your short-term loss carryover gets reduced to $2k - your long-term carryover stays at $10k. This is really important because short-term gains are taxed as ordinary income (up to 37%) while long-term gains get preferential rates (0%, 15%, or 20%). You want to make sure you're applying the right type of loss against the right type of gain to maximize your tax benefit.

Great question about tracking capital loss carryovers! I've been dealing with this exact situation for the past 3 years after some unfortunate investment decisions during the market volatility. One thing I learned the hard way is to keep detailed records beyond just relying on tax software. While most software does track carryovers reasonably well, I've found it helpful to maintain my own backup documentation. I keep a simple folder with: 1. Copy of each year's Schedule D and Capital Loss Carryover Worksheet 2. All 1099-B forms and investment statements 3. A one-page summary showing my remaining carryover balance each year The reason this became important for me is that I switched from TurboTax to FreeTaxUSA one year, and while the new software asked about prior year carryovers, having my own records made the transition seamless. I could easily verify that the carryover amounts were entered correctly. Also, don't forget that if you have a really large loss like yours, you might want to consider the timing of future gains strategically. For instance, if you're planning to sell some winners, you might want to spread those sales across multiple years to make the most of your loss carryover rather than using it all up in one year with a large gain. The 9+ year timeline you mentioned is actually pretty common with substantial losses. Just stay organized and you'll be fine!

•This is really helpful advice! I'm curious about the strategic timing you mentioned - if I have a $28k loss carryover like the original poster, would it make sense to deliberately realize some gains each year to use up the carryover faster? Or is it generally better to just let it carry forward naturally and take the $3k deduction against ordinary income each year? I'm trying to figure out if there's an optimal strategy for managing large loss carryovers.
