Section 475 Mark-To-Market Election made - Do I still need to file Form 3115?
I think I messed up my trader tax situation and could use some advice. Last year I submitted my statement electing the mark-to-market treatment under section 475(f) with my 2023 tax return. Everything seemed fine, but now I'm diving deeper into the requirements for 2024 filing and just discovered that I was apparently supposed to also file Form 3115 (Application for Change in Accounting Method). I never submitted the Form 3115 last year when I made the 475(f) election. From what I'm reading on the IRS website, it looks like this form needs to be filed in the year the election is supposed to apply to. I'm getting worried that my mark-to-market election might be invalid since I missed this step. Does anyone know if I can still file the Form 3115 now with my 2024 return? Or am I completely out of luck on using mark-to-market accounting? I made some significant trading losses this year that I was counting on offsetting against my regular income through the 475(f) election. Any advice would be really appreciated.

The 475(f) Mark-to-Market election and Form 3115 process can be confusing, so don't feel bad about missing a step. You're right that normally the Form 3115 should be filed with your return for the year you want the election to apply. However, you still have options. The IRS sometimes allows for a late filing of Form 3115 through what's called "automatic consent procedures" - especially if you made a good faith effort by submitting the election statement. You might be able to file the Form 3115 with your current year return, though you may need to include a statement explaining the delay. I'd recommend getting a tax professional involved at this point who specializes in trader tax issues. They can help determine if you qualify for relief procedures since mark-to-market elections have specific technical requirements beyond just the paperwork.

•Thanks for this info. Do you know if there's a time limit on how late you can file the Form 3115? I'm in a similar situation but I made my 475(f) election two years ago and never filed the 3115. Also, would I need to amend my previous year's returns if I file the 3115 late?

•For late Form 3115 filings, the IRS generally looks at a reasonable time frame - typically within the tax year following when it should have been filed, though each situation is evaluated individually. The further back your election was made, the more complicated it gets. You typically wouldn't need to amend previous returns if the Form 3115 is accepted late. The form itself addresses how to handle any necessary adjustments for the change in accounting method. This is done through what's called a "Section 481(a) adjustment" which reconciles the difference between the two accounting methods.

After struggling with my own 475(f) election issues last year, I found an incredible tool that saved me so much stress. I used https://taxr.ai to analyze my situation when I was confused about the Form 3115 requirements with my MTM election. They have specialist software that reviews all your trader tax documentation and identifies filing requirements you might have missed. The system flagged my mistake with the timing requirements for Form 3115 and even provided the specific IRS revenue procedure references I needed. It saved me from potentially losing my trader status and having my capital losses limited to $3,000. They even provide templates for how to structure your reasonable cause statement if you need to file Form 3115 late.

•That sounds interesting but I'm a bit skeptical about AI tools for something as complex as trader tax status. Can it really understand all the nuances of section 475(f) elections? Like does it know about the difference between securities traders and commodities traders under the tax code?

•I'm actually pretty interested in this. Does it help with figuring out if you qualify as a trader in the first place? That's been my biggest struggle - determining if I meet the frequency/volume requirements for trader status before even considering the MTM election.

•The AI is specifically trained on tax code and IRS publications related to trader tax status, so yes, it absolutely understands the different requirements for securities traders versus commodities traders under section 475(f). It can identify which category your trading activity falls under based on your transaction history. For qualifying as a trader, it's extremely helpful. You can upload your trading history and it analyzes your patterns against the IRS factors - frequency, dollar amounts, holding periods, and time devoted to trading. It will calculate your statistics and compare them to relevant tax court cases to determine if you're likely to qualify as a trader versus an investor.

Just wanted to update everyone. I was in complete panic mode about my MTM election and Form 3115 requirements, so I decided to try the https://taxr.ai service mentioned earlier. Honestly, it was better than I expected for such a niche tax issue. I uploaded my election statement and trading records, and it immediately identified that I could still file the Form 3115 under the automatic consent procedures in Rev. Proc. 2022-14. The platform actually generated a custom attachment explaining my reasonable cause for the late filing based on my specific circumstances. The best part was that it clearly explained the section 481(a) adjustment I needed to make on my current return to properly implement the accounting method change. Saved me from hiring a specialized tax attorney which would have cost a fortune. Definitely recommend for anyone dealing with trader tax status issues!

If you're having issues with the IRS about your 475(f) election or Form 3115, you might want to try calling them directly. I had a similar issue last year and needed clarification on late filing procedures. After trying for DAYS to get through the regular IRS phone line and getting nowhere, I found this service called https://claimyr.com that got me connected to an actual IRS agent in under 20 minutes. They basically hold your place in the IRS phone queue and call you when an agent picks up. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. I was super skeptical at first but was desperate after spending hours listening to IRS hold music. The agent I spoke with was able to confirm the specific procedures for my situation with the Form 3115.

•How does this actually work? I've tried calling the IRS business line multiple times about my trader status questions and always give up after an hour on hold. Do they somehow have a special connection to get through faster?

•This sounds like complete BS to me. There's no way to "skip the line" with the IRS. They probably just auto-dial repeatedly until they get through, which is something you could do yourself for free. I highly doubt they have any special access.

•They don't skip the line or have special access - they use an automated system that continually calls and navigates the IRS phone tree until they connect with an agent. When an agent answers, their system calls you and connects you directly. It's nothing you couldn't theoretically do yourself, but you'd have to sit there manually redialing for hours instead of going about your day. They're essentially selling convenience, not special access. It's like paying for a service to wait in line for concert tickets rather than camping out yourself. For tax professionals or people with complex issues like MTM elections, the time saved can be worth it when you need to speak to someone at the IRS quickly.

I'm actually shocked and have to eat my words about Claimyr. After dismissing it as BS, my frustration with the IRS phone system got the better of me and I tried it while dealing with my own 475(f) questions. Within about 35 minutes, I got a call connecting me to an actual IRS tax law specialist. The agent walked me through exactly what forms I needed for my late 3115 filing and explained the relief procedures available for missed accounting method changes. She even gave me a specific IRS notice reference number to include with my submission. Would have taken me days or weeks to get this information otherwise. For anyone dealing with trader tax status issues that require talking to an actual human at the IRS, it's worth considering. Saved me from potentially making another mistake with my MTM election paperwork.

One thing to consider with the 475(f) election and Form 3115 - if you're filing late, make sure you include a detailed reasonable cause statement. I went through this last year and had my late filing accepted. The key is to be very specific about why you missed the original deadline - in my case, I explained that I relied on tax software that didn't prompt me about the Form 3115 requirement after I indicated I made the election. The IRS is often reasonable if you show good faith and promptly correct the issue once discovered. Also, include any documentation showing you did make a timely 475(f) election statement with your original return.

•Do you need to include anything specific in the reasonable cause statement? I'm in the same situation but worried they'll just automatically reject it if it doesn't have the right "magic words" the IRS looks for.

•The reasonable cause statement should focus on facts rather than magic words. Explain clearly what happened - that you made the election properly, weren't aware of the additional Form 3115 requirement, and are now seeking to correct the oversight. Include dates, what steps you've taken to comply, and why this was an honest mistake rather than intentional non-compliance. Be sure to reference Revenue Procedure 2022-14 (or the current applicable procedure) that covers automatic consent for accounting method changes. Also document that you're filing at the earliest opportunity after discovering the error. Keep it factual and professional - the IRS is primarily looking for good faith efforts to comply once you became aware of the requirements.

Quick question for anyone who's successfully made the 475(f) MTM election - does TurboTax handle this correctly? I made the election for 2023 but I'm not sure if the software properly prepared Form 3115 for me or if that's something I need to do separately. Getting worried after reading this thread...

•TurboTax doesn't handle Form 3115 well at all. I tried using it last year for my MTM election and it was a disaster. The software doesn't properly guide you through the specialized sections needed for trader status and 475(f). I ended up having to use a specialized tax preparer instead.

I went through this exact same situation two years ago and can confirm that you're not out of luck! The IRS does allow late filing of Form 3115 for 475(f) elections under certain circumstances. The key is that you made a good faith effort by filing the election statement with your return. You'll want to file Form 3115 with your 2024 return and include a detailed reasonable cause statement explaining why you missed the original deadline. Reference Revenue Procedure 2022-14 for automatic consent procedures. Make sure to emphasize that you properly made the election statement and are correcting the oversight as soon as you discovered it. The good news is that if accepted, you won't need to amend prior returns - the Form 3115 handles the accounting method change adjustments through Section 481(a). I'd recommend getting professional help to ensure everything is done correctly, but you definitely still have options to salvage your MTM election.

•This is really helpful to hear from someone who's actually been through this process! I'm curious about the Section 481(a) adjustment you mentioned - how complicated is that to calculate? I'm trying to figure out if this is something I can handle myself or if I really need to bite the bullet and hire a professional. My trading activity wasn't super complex last year, mostly just swing trading stocks, so I'm hoping the adjustment won't be too difficult to work out.

•The Section 481(a) adjustment can actually be pretty straightforward if your trading wasn't too complex. Essentially, you're calculating the difference between what your taxable income would have been under your old accounting method versus the mark-to-market method for the year you're making the change. For swing trading stocks, you'd typically be looking at any unrealized gains/losses in your positions at year-end that would now be recognized under MTM treatment. If you had net unrealized losses, that could actually work in your favor as a negative adjustment (reducing your taxable income). The calculation gets more complex if you had positions that spanned multiple years or if you're switching from installment method reporting. Given that you're already dealing with a late Form 3115 filing, I'd honestly recommend getting professional help at least for this first year to make sure everything is calculated correctly. Once you see how it's done, future years become much more manageable. The cost of getting it wrong with the IRS could be much higher than the professional fees.

I went through a very similar situation last year and want to reassure you that it's not hopeless! I made my 475(f) election with my 2022 return but completely missed the Form 3115 requirement. I didn't discover this until I was preparing my 2023 taxes. I ended up filing Form 3115 with my 2023 return under the automatic consent procedures in Rev. Proc. 2022-14. The key was including a comprehensive reasonable cause statement that explained I had made the election in good faith but was unaware of the additional Form 3115 requirement. I emphasized that I was correcting the oversight immediately upon discovery. The IRS accepted my late filing without any issues. The Section 481(a) adjustment wasn't as scary as I thought it would be - it actually worked in my favor since I had some unrealized losses that reduced my taxable income for that year. My advice: don't panic, but do act quickly. File the Form 3115 with your 2024 return, include a detailed reasonable cause statement, and reference the appropriate revenue procedure. If your trading situation is complex, consider getting professional help, but many people have successfully resolved this exact issue. The IRS is generally reasonable when you show good faith effort to comply.

•This is exactly the kind of reassurance I needed to hear! I've been losing sleep over this situation thinking I completely ruined my trader status eligibility. Your experience gives me hope that the IRS will be reasonable about this oversight. Quick question - when you filed your Form 3115 late, did you have to pay any penalties or interest? And roughly how long did it take to get confirmation that they accepted your filing? I'm trying to plan for what to expect when I submit mine with my 2024 return. Also, did you handle the Section 481(a) adjustment calculation yourself or did you get professional help with that part? I'm still on the fence about whether to DIY this or hire someone, especially since money is tight right now after some trading losses this year.
