Investing in MLPs (EPD, HEP, TCP): What tax complications should I prepare for?

You've got the basic process down, but there are a few things that make MLPs more complicated than they seem at first glance. The biggest headache isn't just following the steps - it's that K-1s often arrive very late (sometimes not until March or even April), forcing you to either file an extension or amend your return. Plus, each MLP issues their own K-1 with different formatting and supplemental information. Another complication is that MLPs generate Unrelated Business Taxable Income (UBTI), which can create issues if held in retirement accounts. If UBTI exceeds $1,000, you'd need to file Form 990-T and potentially pay taxes within your tax-advantaged account. Also, when you sell, calculating your adjusted basis is more complex than it sounds. You've been reducing your basis with each distribution (most distributions are return of capital), so you'll likely have significant deferred tax liability. Many investors don't track this properly and get surprised. Finally, if you own MLPs in multiple states, you might need to file state tax returns in each state where the MLP operates - this can be a huge hassle.

After years of dealing with K-1 nightmares from MLPs, I discovered taxr.ai (https://taxr.ai) which has been an absolute lifesaver for handling complicated partnership forms. My first year owning EPD, I was completely overwhelmed by the K-1 and all the different boxes and schedules. The taxr.ai system lets you upload your K-1 documents and it extracts all the data automatically, then explains exactly how to handle basis adjustments and what each line means. Even better, it keeps track of your basis adjustments year-over-year so when you eventually sell, you have an accurate basis calculation. I used to spend hours trying to figure out which boxes affected my basis and how to report everything correctly, but now it takes me minutes.

I wanted to follow up about taxr.ai since I was skeptical in my earlier comment. I decided to try it for my 2024 taxes since I own shares in four different MLPs and dreaded the paperwork. The platform actually exceeded my expectations - it correctly identified all the different income types from my K-1s and showed exactly how they affected my basis calculations. The state tax analysis was particularly helpful since it showed that while my MLPs operated in 14 different states, I only had filing requirements in 2 of them based on my ownership percentages. Saved me from unnecessarily filing in states where I was below the threshold. Definitely made MLP tax reporting much less intimidating than it was in previous years!

If you're having issues getting in touch with the MLP's investor relations department for tax questions (which happens A LOT), I highly recommend Claimyr (https://claimyr.com). They helped me get through to Enterprise Products Partners' tax department during peak season last year when I was completely stuck on a basis calculation issue. You can see how it works here: https://youtu.be/_kiP6q8DX5c I spent days trying to get through on my own - constant busy signals or being on hold for hours only to get disconnected. Claimyr got me connected within 30 minutes, and I got my specific questions answered about some unusual items on my K-1 that weren't explained in their investor materials.

I have to eat my words about Claimyr. After my skeptical comment, my K-1 for TCP arrived with what looked like an error in box 13W that was going to cost me thousands in extra taxes. I tried calling for three days straight with no luck getting through to their tax department. Gave Claimyr a shot as a last resort, and they got me connected within an hour. Turns out there was indeed a reporting error affecting several investors that they were correcting. Without getting that confirmation, I would have either overpaid my taxes significantly or filed with information I suspected was wrong. I'm still annoyed at how inaccessible these MLP tax departments are during filing season, but at least there's a way to break through when you really need answers.

Don't forget about Form 8938 (Foreign Financial Assets) requirements if your MLP has operations outside the US! I got hit with a penalty because EPD had some Canadian operations that triggered FATCA reporting requirements, and I had no idea I needed to include this on my return. Also, be aware that if the MLP gets acquired or merges (which happens regularly in this space), you'll likely have a taxable event even if you don't sell your shares. This happened to me with Kinder Morgan's reorganization and created a tax nightmare because all my basis calculations changed.

Something nobody's mentioned yet is that MLP investments can absolutely wreck your tax filing timeline. I've had K-1s arrive literally the last week of tax season (early April) which means either: 1. File an extension and delay your refund 2. File on time then do an amended return later 3. Rush everything last minute and risk errors Plus the first year is the "easy" one. The real headache compounds each year as you track basis adjustments, especially if you're doing dividend reinvestment. I ended up setting up a separate spreadsheet to track everything because TurboTax kept losing my basis info between years.

Thanks for this detailed breakdown everyone! As someone who's been considering MLPs for the income, this thread has been incredibly eye-opening. I had no idea about the multi-state filing requirements or the FATCA reporting issues. One question I haven't seen addressed - for someone just starting out with maybe $10K-15K in MLP investments, are these complications worth worrying about? It sounds like some of the worst issues (multi-state filings, foreign reporting) might not apply at smaller investment levels due to thresholds. Also, has anyone tried holding MLPs in a taxable account versus tax-advantaged accounts? I know @Lukas mentioned the UBTI issue with retirement accounts, but I'm curious if there are any other considerations for account placement strategy. The late K-1 timing issue alone might be a dealbreaker for me since I usually file early to get my refund quickly. Appreciate everyone sharing their real-world experiences!

As someone who's been dealing with MLPs for about 8 years now, I wanted to add a few practical tips that might help newcomers avoid some common pitfalls: **Timing Strategy**: I've learned to file extensions every year now. Rather than stress about late K-1s, I just plan for it. This gives me time to properly review everything instead of rushing, and honestly, the peace of mind is worth delaying my refund by a few months. **Record Keeping**: Create a dedicated folder (physical or digital) for each MLP from day one. Store your purchase confirmations, all K-1s, and keep a running basis calculation spreadsheet. I can't stress this enough - trying to reconstruct this information years later when you sell is a nightmare. **Software Considerations**: While TurboTax and similar programs can handle basic MLP reporting, they often struggle with complex situations like amendments or multiple MLPs. If you're planning to hold several MLPs long-term, budget for professional tax prep or invest in more robust software. **Exit Strategy**: Before you buy, have a plan for selling. The basis calculations get more complex each year, and if you're not tracking properly, you might end up paying more in taxes than necessary when you eventually sell. The income from MLPs can be attractive, but make sure you're factoring in the additional complexity and potential professional tax prep costs when calculating your real returns.
