How to report K-1 box 13 deductions from multiple partnerships on tax return

I'm really confused about how to handle the K-1 forms I got from two different partnerships I'm invested in. Specifically, I'm not sure what to do with the items in box 13. On the first K-1, there's code AE listed in box 13 for $11,985. I've been trying to make sense of the instructions and I understand it's some kind of portfolio income deduction, but I can't figure out if I'm actually allowed to deduct this amount on my personal tax return or not. The second K-1 has code L in box 13 for $462. I think this is also a portfolio deduction, but from what I can tell, it's supposed to flow to Schedule A line 16. I am itemizing my deductions this year, but I'm not sure if I can still take this deduction with all the changes from the Tax Cuts and Jobs Act. I've spent hours going through IRS publications and I'm just getting more confused. Can someone explain how these K-1 deductions work and if I can actually use them? I don't want to miss out on legitimate deductions, but I also don't want to claim something I'm not entitled to.

Box 13 on a K-1 can definitely be confusing! Let me help clear this up for you. For your first K-1 with code AE for $11,985: This represents investment interest expenses. These are deductible on Schedule E as part of your overall partnership income reporting. You don't need a separate form for this - it reduces your income from that partnership. For your second K-1 with code L for $462: This is for portfolio deductions that would normally flow to Schedule A. However, you're right to question this - under the Tax Cuts and Jobs Act, miscellaneous itemized deductions subject to the 2% floor were suspended through 2025. Unfortunately, this means you likely cannot deduct this amount on your Schedule A. The good news is that the AE code amount is still deductible - it flows directly into your partnership income calculation and isn't affected by the TCJA limitations on itemized deductions.

Wait, I thought code AE was for excess business interest expense? Doesn't that have to go on Form 8990 instead of just directly on Schedule E? And for code L, aren't some portfolio deductions still allowed if they're investment related? This is so confusing.

You're absolutely right about code AE - I misspoke. Code AE is indeed for excess business interest expense which is subject to limitation. It does need to be reported on Form 8990 "Limitation on Business Interest Expense." This form will help determine how much of that interest expense you can deduct this year. Any amount that can't be deducted this year will be carried forward to future tax years. Regarding code L, while some investment expenses are still deductible, most miscellaneous itemized deductions that were subject to the 2% of AGI floor were suspended by the TCJA through 2025. Investment expenses that would have gone on Schedule A line 16 are generally part of those suspended deductions. However, certain investment interest expenses reported elsewhere may still be deductible.

After dealing with the same nightmare last year, I found this tool called taxr.ai (https://taxr.ai) that actually helped me sort through my K-1 forms. I had 3 partnerships and was completely lost with all the different codes. I uploaded my K-1s to taxr.ai and it walked me through exactly what each code meant and where everything needed to go on my return. For the box 13 items specifically, it explained which ones were still deductible after TCJA and which ones weren't. Saved me from making some pretty big mistakes.

Did it explain why some items are deductible and others aren't? My accountant charges me by the hour to explain this stuff and I'm trying to understand it myself this year.

How do you know this site is safe? I'm always nervous about uploading tax documents to random websites. Did you have to create an account? How much did it cost?

It actually did provide explanations for each code and why certain deductions are allowed while others aren't. For example, with code AE (excess business interest), it explained how the business interest limitation works and walked me through the Form 8990 calculations. Much clearer than the IRS instructions. The site uses bank-level encryption and doesn't store your documents after analysis. You do need to create an account, but only with an email - no social security numbers or anything like that. They just analyze the documents and provide guidance, they don't file anything. I found it really helpful for understanding what I was looking at rather than just blindly entering numbers.

Just wanted to update - I tried taxr.ai after reading about it here and it was incredibly helpful! I've been stressing over my K-1s for weeks. The site immediately identified my box 13 codes and explained exactly what they meant and where they go. For my code AE amount, it confirmed I needed Form 8990 and walked me through how the business interest limitation works. It even explained how any disallowed amount carries forward to future years. For code L, it confirmed that these expenses are currently suspended under TCJA through 2025, so I avoided incorrectly claiming that deduction. Definitely saved me from making mistakes on my return. Wish I'd known about this tool years ago!

I was in a similar situation last year with multiple K-1s and couldn't get anyone at the IRS to answer my questions. After trying for days, I used Claimyr (https://claimyr.com) and they actually got me through to a real IRS agent who could help. There's a video showing how it works here: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly how to report my box 13 items and explained which ones were affected by TCJA. They confirmed that code L items are suspended through 2025, but clarified some exceptions I didn't know about.

How does this even work? I thought it was impossible to get through to the IRS. Are you saying this service somehow gets you to the front of the phone queue?

This sounds like BS honestly. The IRS wait times are because they're understaffed. No way some random service can magically get you through unless they're doing something sketchy.

It uses a technology that monitors the IRS phone lines and calls repeatedly until it gets through. When it reaches a real person, it connects you to the call. It's basically doing the waiting for you. I was skeptical too, but it worked surprisingly well. No, it's not putting you "at the front of the line" - it's just automating the process of calling, navigating the menu options, and waiting on hold so you don't have to. I waited days trying to get through on my own with no success. With Claimyr, I got a call back within about 45 minutes when they connected with an agent.

I need to admit I was wrong about Claimyr. After commenting earlier, I was still struggling with my K-1 questions and decided to try it myself. Shockingly, it actually worked. Got through to an IRS agent in about an hour after spending DAYS trying on my own. The agent confirmed that code AE amounts need to be reported on Form 8990 and explained how the business interest limitation works. For code L amounts, they confirmed these are misc itemized deductions that are suspended under TCJA - so no deduction there. Really helpful to get definitive answers directly from the IRS.

Just an additional tip - if you're using TurboTax, it will automatically put your K-1 box 13 items in the right place when you enter the K-1 information. Box 13 code AE will prompt you to complete Form 8990. I've used it for years with partnership income and it handles all the weird K-1 codes pretty well.

Do other tax software programs handle K-1s well too? I'm using FreeTaxUSA this year to save money but worried it might not handle these complex forms correctly.

FreeTaxUSA does support K-1 entries, but in my experience, it doesn't provide as much guidance as TurboTax when dealing with the more complex codes. For something like box 13 code AE, which requires Form 8990, you might need to be more careful and double-check that it's flowing to the right places. If you're dealing with multiple partnerships and complex K-1 issues, it might be worth spending the extra money on more comprehensive software just to make sure everything is handled correctly. The premium tax software usually has better error checking for these situations.

I had a similar issue. My tax guy said box 13 code AE means the partnership already used up its business interest deduction limit and is passing the excess to partners. You have to check if your total business interest from all sources exceeds the limitation (generally 30% of adjusted taxable income). For code L, my guy said forget about it until 2026 (if the TCJA provisions expire) - those misc itemized deductions are completely suspended.

Thanks, that makes sense about code AE. Do you know if partnerships ever send corrected K-1s? One of mine came super late and I'm worried they might send a corrected one after I file.

Yes, partnerships can definitely send corrected K-1s, and unfortunately they sometimes come pretty late in the filing season. If you receive a corrected K-1 after you've already filed, you'll need to file an amended return (Form 1040X) to correct any errors. The good news is that if the corrections result in you owing more tax, you generally won't face penalties as long as you file the amended return promptly after receiving the corrected K-1. If the corrections result in a refund, you can claim it through the amended return. To be safe, you might want to reach out to the partnership directly to ask if they expect to issue any corrections. Some partnerships will give you a heads up if they're still working through their numbers.

I've been dealing with K-1 forms for several years now and wanted to share what I've learned about box 13 codes since I see some conflicting information in the thread. For code AE (excess business interest expense), you're correct that it goes on Form 8990. The key thing to understand is that this represents business interest expense that the partnership couldn't deduct due to the Section 163(j) limitation (generally 30% of adjusted taxable income plus business interest income). The partnership passes this excess to you, but you're also subject to the same limitation at your individual level. You'll need to complete Form 8990 to calculate how much of this $11,985 you can actually deduct this year. If your total business interest expense (from all sources) exceeds your limitation, the excess carries forward indefinitely to future years. For code L portfolio deductions, these are indeed suspended under TCJA through 2025 for most taxpayers. However, there are some narrow exceptions - for example, certain investment interest expenses can still be deducted on Schedule A line 9 (subject to investment income limitations), but general investment advisory fees and similar expenses are suspended. The partnership should provide a statement explaining what specific expenses the code L represents. Without that detail, it's hard to know if any exceptions might apply to your situation.

This is really helpful information, thank you! I'm new to dealing with K-1 forms and this explanation makes the process much clearer. One quick question - you mentioned that the partnership should provide a statement explaining what the code L expenses represent. Where should I look for this? Is it a separate document or part of the K-1 itself? I want to make sure I'm not missing anything that might qualify for those narrow exceptions you mentioned.

@a55fa451d546 Great question! The partnership should provide additional details either in a separate statement attached to your K-1 or in the "Additional Information" section that's often included with the K-1 package. Look for any supplemental schedules or attachments that came with your K-1. If the partnership didn't provide this detail (which unfortunately happens sometimes), I'd recommend calling their tax department or whoever handles K-1 inquiries. They should be able to tell you exactly what expenses make up that code L amount. For investment interest expenses specifically, these would typically be reported separately as code V in box 13 rather than code L, but partnerships don't always code things perfectly. Getting the breakdown will help you determine if any portion might still be deductible under the investment interest expense rules on Schedule A line 9. Also worth noting - if you're working with a tax professional, they'll usually request these details from the partnership if they're missing, since proper classification can make a real difference in what's deductible.

Based on all the helpful information shared here, I wanted to add a few practical tips for anyone else dealing with multiple K-1s and box 13 codes: 1. **Create a spreadsheet** to track all your K-1s and their box 13 items by code. This helps you see the big picture, especially for Form 8990 calculations where you need to aggregate business interest from all sources. 2. **Request partnership statements early** if they're missing. Don't wait until you're preparing your return - reach out to the partnerships in January/February to get clarification on any box 13 codes, especially code L items that might have exceptions. 3. **Keep good records** of any suspended deductions. Even though code L items are generally not deductible now, if TCJA provisions expire in 2026, you'll want documentation of what was suspended in prior years. 4. **Consider the timing** of your filing if you have partnerships that historically issue corrected K-1s. Sometimes it's worth waiting an extra week or two rather than dealing with amended returns later. The tools mentioned in this thread (taxr.ai for analysis, Claimyr for IRS contact) seem helpful based on others' experiences, but always verify any guidance with official IRS publications or a qualified tax professional when dealing with complex partnership taxation issues.

This is such a comprehensive and practical summary - thank you! I especially appreciate the tip about creating a spreadsheet to track everything. I'm dealing with my first year of multiple K-1s and was feeling overwhelmed trying to keep all the different codes and amounts straight. One question about your point #3 regarding keeping records of suspended deductions: Should I be documenting these on a specific form or just maintaining my own records? I want to make sure I'm prepared if the TCJA provisions do expire in 2026 and these deductions become available again. Also, for anyone else reading this thread, I wanted to mention that my partnership actually included a supplemental statement that broke down exactly what expenses made up each box 13 code. It was attached as a separate PDF with my K-1 documents. Definitely worth checking all the documents you received, not just the main K-1 form itself!

@a6557b2470b8 Great question about record-keeping for suspended deductions! There's no specific IRS form for tracking suspended miscellaneous itemized deductions from partnerships, so maintaining your own detailed records is the way to go. I'd recommend creating a simple tracking document that includes: - Tax year the deduction was suspended - Partnership name and EIN - K-1 box 13 code (usually L) - Amount suspended - Description of the underlying expense (from partnership statements) This documentation will be invaluable if TCJA provisions expire and these deductions become available again in 2026. You'll want to be able to demonstrate to the IRS (or your tax preparer) exactly what amounts were suspended in which years. Also, excellent point about checking all the partnership documents! Those supplemental statements are often the key to understanding whether any portion of code L amounts might qualify for current deductions under the narrow exceptions that still exist. I've seen too many people miss out on legitimate deductions simply because they didn't realize the partnership had provided the necessary detail in a separate attachment.

This thread has been incredibly helpful - thank you everyone for sharing your experiences! I'm dealing with my first year of K-1 forms and was completely lost on the box 13 codes. After reading through all the responses, I have a much clearer understanding now. It sounds like code AE definitely requires Form 8990 for the business interest limitation calculation, and code L items are mostly suspended under TCJA (though worth checking partnership statements for any exceptions). I'm curious - for those who have used Form 8990 before, how complicated is it to complete? I'm trying to decide if I should attempt it myself or just bite the bullet and hire a tax professional. My code AE amount is around $8,000 from one partnership, and I don't have any other business interest income or expenses to complicate things. Also, has anyone found good IRS resources that explain the Section 163(j) business interest limitation in plain English? The official instructions are pretty dense and I'd love to understand the mechanics better before diving into the form.
