What happens if I don't report my K-1 from my Energy Transfer LP investment?
I've owned some shares of Energy Transfer LP (ET) for about 6 years now and it's been one of my better performing investments. I don't have a huge position but it generates consistent dividend income which I've been reinvesting. Recently I realized that I should be getting a K-1 form for this investment, but I honestly don't think I've ever received one or reported it on my taxes. Now I'm freaking out a bit wondering what happens if I don't report the K-1? I've been filing my taxes using TurboTax and just reporting the dividends that show up on my 1099-DIV from my brokerage. Am I going to get in trouble with the IRS? Do I need to file amended returns for previous years? How serious is this mistake?

You definitely need to report K-1 income from your Master Limited Partnership (MLP) investment. When you own shares in Energy Transfer LP, you're technically a partner in the business, not just a shareholder. That's why you get a K-1 instead of just having everything on a 1099-DIV. The IRS receives a copy of your K-1, so they already know about this income. Not reporting it could potentially trigger an audit or at minimum a letter from the IRS asking for additional tax payment plus interest and possibly penalties. The K-1s from MLPs are usually available online through the company's investor relations portal - many don't mail them anymore. As for amending returns, technically you should file amended returns for any open tax years (generally the last three years). The statute of limitations is typically three years, but it can be longer in cases of substantial underreporting.

•If I'm in a similar situation but I only have like $200 in distributions annually, would the IRS really care enough to audit me? I mean, the tax difference has to be minimal right?

•The dollar amount doesn't necessarily determine whether the IRS will follow up. They have automated systems that flag discrepancies between what's reported to them (via your K-1) and what you report on your return, regardless of the amount. Even small amounts can generate notices because it's an automated process. Also, MLP taxation is more complex than just the distribution amount - the K-1 contains information about your share of the partnership's income, deductions, credits and other items that affect your tax liability in various ways.

I went through something similar with my MLP investments and found that using https://taxr.ai was literally a game changer! I had multiple K-1s I hadn't properly reported for a couple years and was freaking out about what to do. I uploaded my K-1 PDFs to the site and it analyzed everything, explaining exactly what I needed to report and how. The system even helped me understand which previous tax years I needed to amend and gave me a clear breakdown of how the K-1 income affects different parts of my tax return. It saved me hours of confusion trying to decipher those complicated forms!

•Does it also help you figure out how this affects your basis in the investment? That's the part that always confuses me with MLPs.

•How accurate is this compared to talking with a CPA? I'm nervous about trusting tax software with something as complicated as K-1s when I don't even understand them myself.

•Yes, it actually does track your basis adjustments! It shows how your distributions and allocated income affect your basis over time, which is super helpful for when you eventually sell. Regarding accuracy, I found it to be extremely reliable. The explanations were actually clearer than what I got from my CPA, who honestly seemed annoyed by all my questions about the K-1. The software provides references to specific tax code sections and explains everything in plain English. I still had my CPA review everything, but he was impressed by how thorough the analysis was.

Just wanted to follow up about my experience with taxr.ai - I decided to give it a try after reading about it here. I had 3 different MLPs with K-1s I'd been confused about for years. The platform analyzed all my forms and produced a super clear report explaining exactly what numbers go where on my tax return. It even highlighted that I'd been calculating my basis all wrong which could have been a huge problem if I sold my shares! Definitely recommend checking it out if you're dealing with K-1 confusion.

If you need to talk to the IRS about this situation (which honestly might be a good idea), good luck getting through to them. I spent TWO WEEKS trying to reach someone about my K-1 issues. Finally found this service called https://claimyr.com that got me connected to an IRS agent in under 45 minutes when I'd been trying for days on my own. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was able to discuss my unreported K-1 situation with them and got clear guidance on how to handle amending my returns. The agent was actually super helpful once I finally got through to a human! They walked me through the process and helped me understand which forms I needed for the amendments.

•Wait, how does this service actually work? Does it just call the IRS for you or something? I don't understand how a third party can get you through the phone queue faster.

•This sounds like a scam honestly. Nobody can magically get you through to the IRS faster. They answer calls in the order received. I'll believe it when I see it.

•It doesn't call for you - it uses technology to navigate the IRS phone system and waits on hold for you. When they reach a human agent, you get a call back so you can talk directly to the IRS representative. It's basically automating the hold process so you don't have to sit there listening to the horrible hold music for hours. It's definitely not a scam. The technology just helps navigate the complex IRS phone tree and stays on hold so you don't have to. When they reach an agent, you get connected directly to talk with them yourself - they don't talk to the IRS for you or anything like that.

I need to eat my words here. After posting my skeptical comment, I decided to try Claimyr anyway since I've been trying to reach the IRS about my K-1 issues for weeks. I was honestly shocked when I got a call back in about 35 minutes saying they had an IRS agent on the line! I was able to explain my situation with unreported K-1s from my MLPs, and the agent walked me through exactly what I needed to do. I'm still in disbelief that it actually worked after spending hours upon hours trying to get through myself. Totally worth it just for the peace of mind of knowing exactly what steps I need to take now.

Just to add another dimension to this - failing to report K-1 income doesn't just affect your federal taxes. The states can come after you too. I didn't report MLP income for 3 years and got notices from not just the IRS but also my state tax authority. They charged separate penalties and interest. And some MLPs operate in multiple states so you might technically need to file in those states too! Its a mess honestly.

•Wait what?? I might need to file tax returns in multiple states just because my MLP operates there? Even if I've never been to those states??

•Yep, it's called "nexus" - if the MLP has business operations in a state, as a partner you may have filing requirements there. Most MLPs provide state filing information on their investor websites. Small investors often fall below the filing thresholds for many states, but it depends on your specific situation and the MLP's operations. Some MLPs operate in 20+ states! This is why many investors hold these in retirement accounts instead of taxable accounts - to avoid the tax complexity.

Has anyone here actually gotten audited specifically for missing a K-1? I've owned a tiny bit of ET for like 4 years and never reported the K-1 and haven't heard anything from the IRS. Maybe they dont care about small accounts?

•I didn't get audited but received a CP2000 notice (not technically an audit) saying my reported income didn't match their records. Had to pay the back taxes plus interest. It was only about $340 in taxes but with interest it came to around $400. This was for a K-1 with about $2,800 in income I hadn't reported.

I'm in a similar boat with Energy Transfer LP - had it for about 3 years and just realized I should have been getting K-1s. I checked my brokerage account and found them buried in the tax documents section that I never really looked at carefully. One thing that helped me understand the urgency is that MLPs like ET are required to send copies of all K-1s to the IRS, so they definitely have a record of what you should be reporting. The mismatch between what they expect and what you filed is going to show up in their systems eventually. I'm planning to get caught up on my filings because the penalties and interest just keep accumulating the longer you wait. From what I've read, the "failure to file" penalty can be pretty steep, and then you also get hit with interest on the unpaid taxes. Better to bite the bullet now than deal with a bigger mess later. Also found out that some brokerages don't automatically include K-1 income in your 1099 summary, so you have to manually add it when doing your taxes. That's probably why TurboTax didn't catch it if you were just importing your 1099 data.

•This is really helpful info! I had no idea that brokerages might not include K-1 income in the 1099 summary automatically. That explains why I've been missing this for years - I've just been importing everything from my brokerage into TurboTax without realizing there were separate documents I needed to look for. Do you know if there's a way to tell if my brokerage has been including the K-1 info or not? I'm wondering if I should go back and check all my old tax documents to see what I might have missed. The idea of penalties and interest accumulating is definitely motivating me to get this sorted out ASAP!

The good news is that Energy Transfer LP typically makes their K-1s available online through their investor portal around mid-March each year, so you should be able to access your missing forms going back several years. You'll want to log into ET's investor relations website and look for tax documents. One important thing to understand about MLP K-1s is that they often show losses in the early years due to depreciation and depletion deductions, even when you're receiving cash distributions. This means you might actually owe less tax than you think, or even get refunds when you file amended returns. The key is to act quickly though. While the IRS has up to 3 years to assess additional taxes for most situations, if you substantially underreport income (by 25% or more), they have 6 years. And there's no statute of limitations if you don't file at all. Given that MLPs send copies of all K-1s directly to the IRS, this is definitely on their radar. I'd recommend getting all your K-1s first, then either using tax software that handles MLPs properly or consulting with a CPA who has experience with partnership taxation. The complexity goes beyond just reporting income - there are basis adjustments, potential state filing requirements, and other nuances that can trip you up if you're not careful.

•This is really solid advice! I'm actually dealing with a very similar situation with ET and a couple other MLPs I've owned for years without properly reporting the K-1s. The point about potentially getting refunds due to the depreciation losses is interesting - I hadn't considered that the K-1s might actually work in my favor in some years. Quick question though - when you mention using tax software that "handles MLPs properly," are there specific features I should be looking for? I've been using basic TurboTax for years but I'm guessing the standard version doesn't have the MLP functionality built in. Should I be looking at the premium versions or switching to something else entirely? Also, do you happen to know if Energy Transfer's online portal requires any special account setup, or can I access it with just my SSN and basic account info? I'm hoping I don't need to jump through too many hoops to get those historical K-1s.

•@fce3a9798c5c Great breakdown of the MLP tax complexities! Just to add to your point about the 6-year statute of limitations for substantial underreporting - this is particularly relevant for MLP investors because the income allocation can sometimes be quite different from the cash distributions received. I learned the hard way that even "small" MLP positions can trigger that 25% underreporting threshold if you're only reporting the cash distributions and ignoring the K-1 completely. The IRS calculates this based on your total tax liability, not just the missing MLP income itself. For anyone reading this thread, I'd also recommend checking if your MLP has been doing any major acquisitions or divestitures over the years you owned it. These corporate actions can create additional tax complexities that show up on the K-1s and might affect your basis calculations going forward. Energy Transfer has been pretty active with transactions over the past few years. One more thing - if you're planning to sell your MLP shares eventually, getting the K-1 reporting squared away now is crucial because your cost basis gets adjusted each year based on the K-1 allocations. If you haven't been tracking these adjustments properly, you could end up overpaying taxes on the sale or triggering additional scrutiny from the IRS.

I'm in a very similar situation with my Energy Transfer LP shares - owned them for about 4 years and just discovered I should have been reporting K-1s this whole time. Reading through everyone's experiences here has been both terrifying and helpful! What really caught my attention was the mention of automated IRS systems flagging discrepancies regardless of dollar amount. I always assumed my small position wouldn't matter, but it sounds like that's not how it works. The fact that ET sends copies of all K-1s directly to the IRS means they definitely know what I should have been reporting. I'm planning to log into ET's investor portal this weekend to pull all my historical K-1s. From what I'm reading here, it sounds like I need to prepare for filing amended returns for the past few years. The complexity around basis adjustments and potential state filing requirements is honestly overwhelming, but I'd rather deal with it now than wait for the IRS to come knocking. Has anyone found a good resource or guide that walks through the amendment process specifically for unreported MLP K-1s? I'm trying to figure out if this is something I can handle myself or if I need to bite the bullet and pay for professional help.
