How do I file taxes for Publicly Traded Partnership stocks like UCO? Getting confused by Schedule Ks
I bought some UCO shares back in 2020 and had no clue about it being a Publicly Traded Partnership until I received a Schedule K-1 for 2021 (which arrived in 2022). This was surprising since I hadn't sold any shares that year, but I ended up doing the adjustment and paying the tax. After that headache, I decided to just sell everything in 2022 and actually managed to make a decent profit. But here's where I'm completely lost - looking at the Schedule K-1 forms for both 2021 and 2022, the reported revenue seems even higher than the actual gains showing on my brokerage statement! Does this mean I need to declare income from both the Schedule K-1 AND report the capital gains from my brokerage statement? It feels like I'm getting double-taxed here. How are you supposed to handle PTP investments like UCO properly? I'm seriously confused about how to report this on my 2025 return (for tax year 2024) without overpaying.

The confusion with Publicly Traded Partnerships (PTPs) like UCO is totally understandable! These investments are taxed differently than regular stocks because they're partnerships, not corporations. Here's what's happening: As a PTP owner, you're receiving your share of the partnership's income each year (reported on Schedule K-1) whether you sell any shares or not. This is different from regular stocks where you only report gains when you sell. When you eventually sell your PTP shares, you need to adjust your cost basis to account for the partnership income you've already paid taxes on. Your original purchase price gets increased by the income reported on K-1s and decreased by distributions you received. This prevents double taxation. So you'll report both the K-1 income AND the sale on your return, but the adjusted basis should prevent double taxation. You'll need to complete Form 8949 and Schedule D for the sale, making sure to use your adjusted basis.

•Thanks for explaining! I'm in a similar situation with KYN. So just to make sure I understand - if I originally bought at $40 per unit, then over time had $15 of K-1 income I paid taxes on, and received $8 in distributions, my adjusted basis would be $47 ($40 + $15 - $8)? Then when I sell, I use that $47 as my cost basis?

•Your understanding is exactly right! Your adjusted basis would be $47 in that example. You start with your original purchase price ($40), add the income reported on K-1s that you've already paid taxes on ($15), and subtract any distributions received ($8), giving you an adjusted basis of $47. When you eventually sell your PTP units, you'd use this $47 adjusted basis to calculate your gain or loss. This adjustment process is specifically designed to prevent the double taxation issue that concerned the original poster. It can be a bit more paperwork, but it ensures you're not paying taxes twice on the same income.

After struggling with PTP tax reporting for years, I finally found a service that made this process so much easier. I was constantly messing up the adjusted basis calculations and potentially overpaying taxes until I discovered https://taxr.ai which actually specializes in partnership K-1 analysis. Last year when I got K-1s from multiple PTPs including UCO and AMLP, I uploaded them and it automatically calculated my adjusted basis and identified all the tax forms I needed. Saved me hours of frustration trying to figure out if I was handling the basis adjustments correctly.

•Does it really work with the more complicated PTPs? I have some MLP investments that produce ridiculously complex K-1s with state filings in like 20+ states I don't even live in. Does this handle that level of complexity?

•I'm skeptical about these tax services. How is this different from just having my accountant handle it? They usually charge me like $75 extra per K-1 and claim these are "complex." Is this service actually going to save me money or just create more confusion?

•It absolutely works with the more complicated PTPs and MLPs. The system is designed specifically for handling complex K-1s including those with multi-state filings. It automatically extracts all the state-specific information and tells you exactly which state forms you need to file - even for those states you don't live in. The difference from an accountant is primarily cost and convenience. While accountants typically charge per K-1 (as you mentioned, around $75 each), this service handles multiple K-1s for a flat rate. Plus, you get instant analysis rather than waiting for your accountant to get to it during busy season. Many users actually share the reports with their accountants to save time and reduce their billable hours.

I wanted to follow up about my experience with taxr.ai after my skeptical comment. I decided to try it with my 5 different MLP investments including a particularly nasty one that had income in 22 states. The service actually exceeded my expectations - it pulled every detail from the K-1s and generated a report showing exactly how my basis had changed over the years. When I sold some ET units this year, the adjusted basis calculation was spot on. My accountant even commented that the documentation was better than what he typically produces! Ended up saving about $850 in accounting fees plus the peace of mind that I wasn't double-paying taxes on my PTP investments. Definitely worth it for anyone dealing with PTPs like UCO.

If you're having trouble getting answers about your PTP tax situation directly from the IRS (which is likely because these questions get complex), I had amazing results using https://claimyr.com to actually speak with a real IRS agent. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c I was in complete tax confusion about my PTPs and needed clarification on passive activity loss limitations with my UCO and AMLP investments. After spending hours getting nowhere with the regular IRS phone line, Claimyr got me through to an actual tax law specialist in 20 minutes who walked me through the specific rules for my situation.

•How does this actually work though? I thought the IRS phone lines were just impossible to get through regardless. Are they somehow jumping the line or what? I've literally spent full days on hold before.

•This sounds too good to be true. I've tried calling the IRS about my PTP issues several times and just gave up after hours on hold. Is this service just going to charge me and then I'll still end up waiting forever? Not sure I buy that they have some magic way to get through.

•It works by using an automated system that continuously calls the IRS using optimal timing strategies and navigates through all the phone prompts for you. When a line opens up, you get a call back and are already through the queue - you just need to pick up and you're talking to an IRS agent. No waiting on hold at all. They don't have special access to the IRS or anything improper - they've just perfected the calling strategy after thousands of calls and know exactly when and how to call for minimum wait times. The service actually tells you your estimated wait time upfront, and you only pay if they get you through within that timeframe. I spent literally 6+ hours trying on my own before using this, so getting through in 20 minutes felt like magic.

Wanted to report back after trying Claimyr for my PTP tax questions. I was totally skeptical (as you saw in my previous comment), but I was desperate to get clarity on some passive loss carryovers with my MLP investments before filing this year. I tried the service yesterday morning - they estimated a 35 minute wait, but I actually got connected to an IRS tax law specialist in 22 minutes. The agent walked me through exactly how to handle the basis adjustments for the UCO shares I sold and confirmed I was calculating everything correctly. Saved me from potentially making a $2,400 error on my return! I've been trying to get through to the IRS for MONTHS on my own with no success. This was absolutely worth it.

Has anyone used TurboTax for reporting PTPs like UCO? Their interview process gets super confused when I enter the K-1 information and then also try to report the sale. Last year it seemed like it was double-counting my income and I ended up having to use the forms view to fix everything manually.

•TurboTax does handle PTPs but not very elegantly. I've found TaxAct actually has a better interview process for PTPs specifically. It walks you through the basis adjustments more clearly and doesn't try to double-count. I switched last year after having the same issue with TurboTax and was much happier with how TaxAct handled my UCO and AMLP investments.

•Thanks for the TaxAct suggestion. I've been using TurboTax for years and wasn't aware TaxAct might handle these situations better. I'll definitely look into switching for this tax season. I'm getting pretty frustrated with how TurboTax keeps trying to double-count my PTP income. Having to manually fix everything in forms view defeats the whole purpose of using tax software in the first place. Hopefully TaxAct's interview process for the basis adjustments will save me some headaches.

Does anyone know if you need to file Form 8938 (Foreign Financial Assets) for PTPs like UCO? My accountant is saying that because some of the underlying assets in the partnership might be foreign, I might have an FBAR obligation, but that doesn't sound right to me.

•Your accountant is mistaken. UCO is a domestic PTP traded on US exchanges. You only need to file Form 8938 or FBAR for financial assets held outside the US. The fact that UCO might invest in commodities or futures contracts with international exposure doesn't make it a foreign financial asset for FBAR or 8938 purposes. This is a common misconception. You only need to report on those forms if YOU directly hold the foreign assets or accounts. Since you're just holding the PTP units which are domestic securities, there's no FBAR or 8938 requirement here.
