What do those Form 6781 elections mean for SPX and VIX options?
So I switched to using TurboTax desktop software this year after always using their website, and honestly I'm regretting it big time. The website was so much more user-friendly for my trading activities. On the website, I never had issues with my section 1256 contracts - it would just import all that data automatically and handle it. Super convenient. But now with this desktop software, it's only importing my 8949 data and completely ignoring my section 1256 stuff. I'm stuck manually entering everything into Form 6781 and I'm totally confused about these four election checkboxes. I mainly trade SPX options and VIX options, and I think I should be selecting the "Net section 1256 contracts loss election" but I'm not 100% sure. Also, what the heck am I supposed to put for question 8 where it asks for "Account Description"? Anyone who's dealt with this form before, I'd really appreciate some guidance!

The Form 6781 elections can be confusing, especially when switching between different tax preparation methods. Let me break down what those elections mean for you: 1. The "Net section 1256 contracts loss election" allows you to carry back losses from section 1256 contracts to offset gains from the previous 3 years. This can be beneficial if you had profits in prior years and want to recoup some taxes paid. 2. "Mixed straddle election" lets you remove positions from section 1256 treatment when they're part of a mixed straddle. 3. "Mixed straddle account election" is for those who regularly trade both section 1256 contracts and non-section 1256 positions as part of the same strategy. 4. "Mark-to-market election" is typically for traders who want to treat all securities as if sold at year-end. Since you're trading SPX and VIX options (which are section 1256 contracts), if you had a net loss this year, the "Net section 1256 contracts loss election" would make sense if you want to carry back losses. For question 8 about "Account Description," you simply need to identify where these trades occurred - like "Brokerage Account - TD Ameritrade" or "Trading Account - Interactive Brokers.

•Thanks for the explanation. So if I didn't have any significant gains in the previous 3 years, would it still make sense to select the "Net section 1256 contracts loss election"? Or is it pointless in that case? And for the account description, is it okay to just put "Investment Account" or should I be more specific? The trades were spread across multiple brokerages.

•If you didn't have significant gains in the previous 3 years, there wouldn't be much benefit to selecting the "Net section 1256 contracts loss election." It's only useful if you have prior year gains to offset - otherwise, your current year losses would just carry forward. For the account description, it's better to be specific if possible. If your trades were across multiple brokerages, you might want to list them separately or use something like "Various Brokerage Accounts (TD Ameritrade, Schwab, etc.)" to be more accurate. The IRS uses this information to match up with broker reporting.

After struggling with Form 6781 for my options trading last year, I found an incredible tool called taxr.ai (https://taxr.ai) that literally saved me hours of frustration. I was in the exact same situation - switched from TurboTax online to desktop and got stuck with manually entering all my section 1256 contracts. The taxr.ai system automatically categorized all my trades correctly and figured out which elections made sense for my situation. It analyzed my SPX options trading history and actually recommended against making the Net section 1256 contracts loss election in my case because I didn't have enough prior gains to offset. Saved me from a potential audit flag!

•That sounds interesting but kinda too good to be true tbh. Does it actually import from multiple brokerages or do you still have to manually upload everything? I've got accounts at both Fidelity and Tastyworks and entering all these trades is killing me.

•How does it handle mixed positions? I trade both regular equity options and SPX options, and figuring out which ones qualify for section 1256 treatment vs regular treatment has been a nightmare.

•It handles multiple brokerages really well. You just upload your trading statements from each broker (or connect directly with some of the major ones), and it identifies and categorizes everything. I had accounts with three different brokers and it consolidated everything correctly. For mixed positions, it's actually especially good at that. It automatically identifies which contracts qualify for section 1256 treatment (like your SPX options) versus which ones get regular treatment (like equity options). It even flagged a few VIX-related ETF options I had that I was incorrectly treating as section 1256 contracts.

Just wanted to update everyone - I tried out taxr.ai after seeing it mentioned here and wow! It actually worked really well for my section 1256 issues. I was skeptical at first (as you could probably tell from my question), but it correctly identified all my SPX options as section 1256 contracts and handled the mixed straddle situations I had perfectly. It even explained why I shouldn't make the net loss election this year since I didn't have enough gains in previous years to make it worthwhile. The account description thing turned out to be pretty straightforward too - I just listed each brokerage account separately. Definitely recommend checking it out if you're dealing with the same form 6781 headaches.

If you're having trouble with Form 6781 elections, you might want to try calling the IRS directly for guidance. I know that sounds ridiculous because getting through to the IRS is nearly impossible, but I used Claimyr (https://claimyr.com) and got connected to an actual IRS agent in under 15 minutes. They have this system that navigates all the IRS phone menus and waits on hold for you, then calls you when an agent is on the line. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent I spoke with was surprisingly helpful about the election questions and explained exactly what I should put for the account description section based on my specific trading situation.

•How does Claimyr actually work? Does it just auto-dial for you or something? I've spent literally hours on hold with the IRS trying to get clarity on section 1256 treatment.

•This sounds completely made up. I've tried calling the IRS multiple times and it's always "due to high call volume" then disconnect. No way you got through in 15 minutes even with some special service.

•It basically works as a smart autodialer that knows all the IRS phone systems. It calls the IRS, navigates through all the menu options for you, and waits on hold. Then when an actual human agent picks up, it calls your phone and connects you directly. No more waiting on hold for hours! I was definitely skeptical too. I had tried calling the IRS four separate times about my section 1256 contracts and either got disconnected or was on hold for so long I had to hang up. With Claimyr I was literally talking to an agent in under 15 minutes. They must have some system for getting through when the lines aren't as busy or something. All I know is it worked, and the agent answered all my Form 6781 questions.

I have to admit I was wrong about Claimyr. After my skeptical comment, I decided to try it myself because I was desperate for help with my Form 6781 issues. It actually worked exactly as described. I got through to an IRS tax specialist in about 12 minutes. The agent walked me through each of the elections on Form 6781 and explained that for my SPX options trading, I should only check the Net section 1256 contracts loss election if I had gains in previous years that I wanted to offset. For the account description in question 8, she said to simply put the name of my brokerage with "Options Trading Account" after it. Super straightforward once I had someone who could actually explain it. Definitely changed my mind about this service. Worth every penny to not sit on hold for hours.

Here's my understanding of the Form 6781 elections from someone who's been trading section 1256 contracts for years: The Net section 1256 contracts loss election is only useful if you had significant gains in prior years. It lets you go back and essentially "redo" prior year taxes using your current losses. For the account description, I just put "Primary Trading Account - [Brokerage Name]" and never had any issues with the IRS questioning it. One thing to note: make absolutely sure your SPX and VIX options are being properly classified as section 1256 contracts. TurboTax desktop sometimes misclassifies them if you're not careful during import.

•How can you tell if TurboTax is classifying them correctly? I imported a bunch of trades and now I'm worried they might be in the wrong category.

•You need to check if your SPX and VIX options are showing up on Form 6781 rather than on Form 8949. If they're appearing on 8949 (for regular capital gains), then they're being misclassified. In TurboTax desktop, go to the Forms view and search for Form 6781. Your section 1256 contracts like SPX options should be listed there with the correct 60/40 long-term/short-term split. If they're not there or if all your trades are showing on 8949 instead, you'll need to manually reclassify them.

Anyone know if box spreads on SPX options still qualify for section 1256 treatment? I've been using them for pseudo-financing and I'm not sure if I should be checking any of these elections for tax purposes.

•Yes, box spreads on SPX options still qualify for section 1256 treatment because they're comprised of SPX options, which are section 1256 contracts. The strategy doesn't change the underlying tax treatment. Whether you should check any of the elections depends more on your overall tax situation than the specific strategy. If your box spreads resulted in a net loss and you had section 1256 gains in previous years, the "Net section 1256 contracts loss election" might be beneficial. The mixed straddle elections would only apply if you're combining these positions with non-section 1256 positions as part of a unified strategy.

I've been dealing with Form 6781 for my options trading for the past few years, and I totally feel your pain about the desktop vs. online TurboTax issue. The desktop version definitely requires more manual work for section 1256 contracts. A few quick tips that might help: 1. Double-check that your SPX and VIX options are actually being treated as section 1256 contracts in the desktop version. Sometimes the import doesn't categorize them correctly and they end up on Form 8949 instead of Form 6781. 2. For the "Net section 1256 contracts loss election" - only select this if you had significant section 1256 gains in the previous 3 years that you want to offset. If you didn't have prior gains, this election won't benefit you and your losses will just carry forward normally. 3. The account description can be pretty straightforward. I usually put something like "Options Trading Account - [Broker Name]" and have never had issues with the IRS. 4. If you're really stuck, consider reaching out to a tax professional who specializes in trading taxes. The cost might be worth it for the peace of mind, especially if you're dealing with complex positions or significant amounts. The learning curve is definitely steep when switching from the online version, but once you get the hang of it, the desktop version does give you more control over how everything is categorized.
