Help with Schedule K-1 (1065): Calculating Adjusted Basis for small LLC partnership
I'm struggling with figuring out the adjusted basis calculation on my Schedule K-1 (1065). Using tax software has been mostly fine for the straightforward parts - I can handle inputting different box numbers. But I'm totally confused when it comes to the adjusted basis calculation, which apparently determines how much I can deduct. My situation is pretty simple: I work full-time (40hrs/week) at a small LLC that gave me a small percentage partnership interest as a performance bonus last year. The K-1 is super basic with only a few boxes filled in (Boxes 1, 14, and 18). We've been operating at a loss since the company started, so no distributions to worry about. Two main questions: 1) Since I'm a direct employee working full-time, am I considered an "active participant"? But I think I'm "NOT at-risk" because I don't lose anything if the company fails (Item K liabilities = 0). Do I even need to calculate adjusted basis? 2) For the adjusted basis calculation, all I have is Item L (Partner's Capital Account Analysis). Last year's Ending Capital Account was around -$1,300. Tax software requires a non-zero starting adjusted basis - do I just put 0 since last year's ending was negative? This year's Item L shows: Beginning capital: ~ -$4,100 Decrease: ~ -$3,800 Ending: ~ -$7,900 I think the decrease for adjusted basis would be -$3,800, but then I looked at the worksheet on the IRS website (https://www.irs.gov/instructions/i1065sk1/ch01.html) which says adjusted basis less than zero is 0? I'm completely lost at this point.

You've got a few things to unpack here, so let's tackle them one by one. First, yes, working 40 hours per week at the LLC makes you an active participant in the partnership. Your level of involvement easily meets the material participation tests. For the at-risk rules, having $0 in Item K liabilities doesn't automatically make you "not at-risk." Being at-risk relates to what you've personally invested or what you're personally liable for. Since you received your partnership interest as a bonus, your initial at-risk amount would be the value that was included in your income when you received it (if any). Now for the adjusted basis: Yes, you do need to calculate it. The partnership losses can only be deducted to the extent of your basis. When your basis reaches zero, you can't deduct any more losses until your basis increases through contributions, income, etc. Starting with your negative capital account doesn't work for adjusted basis. Your basis can never go below zero (that's why the worksheet stops at zero). Since your capital account was already negative last year, and you didn't mention making any contributions this year, your starting basis for this year would likely be zero. The decrease to your capital account (-$3,800) represents your share of the losses, but you can only deduct those losses to the extent of your basis. If your basis was zero at the beginning of the year and you made no contributions, you wouldn't be able to deduct any of those losses this year - they would be suspended until you build up basis in the future.

•Thank you for the detailed explanation! So to confirm, since I received the partnership interest as a bonus, would my initial basis be the value of the partnership when I received it? The LLC was (and still is) operating at a loss, so I don't think there was any taxable income from receiving the interest. Also, if I have a zero basis and can't deduct any losses now, do these losses just disappear or can I use them in future years if my basis increases?

•If there was no value attributed to the partnership interest when you received it (meaning it wasn't included as taxable compensation on your W-2 or 1099), then your initial basis would likely be zero. This makes sense given the LLC was operating at a loss when you received your interest. The losses don't disappear - they get suspended and can be used in future years when you have sufficient basis. The IRS allows you to carry these losses forward indefinitely until you have enough basis to absorb them. If you were to make a capital contribution to the partnership, or if the partnership starts generating income in the future, your basis would increase and you could begin using those suspended losses.

After struggling with similar Schedule K-1 (1065) basis calculations for my small business investment, I found an amazing tool that made everything clear. I was completely lost trying to figure out my adjusted basis and at-risk amounts until I discovered https://taxr.ai What made the difference for me was uploading my past K-1s and my current one. The system analyzed them together and showed me exactly how my basis had changed over time, plus it gave me the correct amount to enter for my starting basis this year. It specifically handled my negative capital account situation (similar to yours) and explained why my tax software needed a zero entry for starting basis while tracking my suspended losses. The best part was that it showed me a step-by-step calculation worksheet following the exact IRS rules for adjusted basis with partnership losses. Saved me hours of confusion and probably an expensive call to my accountant!

•Does it actually handle the at-risk calculations separately from the basis calculations? My tax guy charges me extra every year because he says the K-1 basis stuff is "complex" but I feel like I'm being overcharged.

•I'm a bit skeptical about using online tools for something as complex as partnership basis. How does it handle things like recourse vs. nonrecourse liabilities? Or Section 754 adjustments if there were any sales of partnership interests? My K-1 has some pretty complicated stuff on it.

•Yes, it absolutely handles at-risk calculations separately from basis calculations! That was actually one of the most helpful parts for me. It clearly showed me where my basis amount and at-risk amount differed, and how that affected what losses I could claim. Definitely could save you from those extra charges. It's actually surprisingly sophisticated for handling complex partnership basis issues. It correctly identified and processed recourse vs. nonrecourse liabilities from my K-1, and even handled the Section 754 adjustment from when another partner sold their interest last year. I was doubtful too, but it matched what my previous accountant had calculated while explaining it much more clearly.

Just wanted to follow up - I tried https://taxr.ai for my Schedule K-1 (1065) basis calculations and I'm honestly blown away. I uploaded my current K-1 and last year's K-1, and it immediately identified that I had suspended losses from prior years that my tax guy never mentioned! It showed me exactly how to calculate my adjusted basis starting from my negative capital account (just like your situation), and explained why certain losses were limited. It even created a personalized worksheet showing exactly what to enter in my tax software. The at-risk calculation was separated out completely from the basis calculation, which cleared up so much confusion. I ended up saving over $900 on my taxes by correctly applying some previously suspended losses that had become deductible. My tax guy missed this entirely last year!

If you're struggling to get help with your Schedule K-1 (1065) adjusted basis questions, I feel your pain. I spent THREE DAYS trying to get through to the IRS Partnership hotline last month with similar questions. Kept getting disconnected after waiting for hours. Finally found this service called https://claimyr.com that got me connected to an actual IRS agent within 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent walked me through the entire basis calculation process for my situation (also received partnership interest as compensation) and confirmed that when starting with a negative capital account, your beginning basis for the tax software should indeed be zero. They also explained how to track the suspended losses so I can use them in future years when my basis increases. Totally changed my understanding of the Schedule K-1 (1065) basis rules and saved me from making a pretty significant error on my return.

•How does this Claimyr thing actually work? I don't understand how they can get you through to the IRS faster than just calling directly. Sounds like they're just charging for something you could do yourself.

•I'm extremely skeptical. The IRS prioritizes calls based on their own systems. There's no way some third-party service can "cut the line" legitimately. Either this is a scam or they're doing something sketchy. Has anyone else actually verified this works?

•It works by using an automated system that navigates the IRS phone tree and waits on hold for you. When they reach a live agent, they call you and connect you directly to that agent. You don't skip any lines - they just handle the waiting part so you don't have to sit on hold for hours. I was skeptical too before trying it. I'm not affiliated with them in any way, just sharing what worked for me. The IRS agent I spoke with was definitely legitimate - they accessed my previous returns and verified my identity through the normal IRS verification process. They helped me understand exactly how to calculate my adjusted basis for my Schedule K-1 (1065) and explained the rules for suspended losses.

I need to eat crow here. After my skeptical comment, I actually tried Claimyr for an issue with my Schedule K-1 (1065) adjusted basis calculation that was similar to the original poster's situation. Not only did it work exactly as promised, but I got connected to an IRS partnership specialist who immediately understood my negative capital account situation. The agent confirmed that with a starting negative capital account and no additional contributions, my beginning adjusted basis would indeed be zero for tax software purposes, and the partnership losses would be suspended until I had future basis. The agent even emailed me specific IRS guidance on tracking suspended losses from partnership interests received as compensation - something I couldn't find anywhere online. Completely solved my Schedule K-1 basis calculation issues in a 15-minute call instead of weeks of research and stress.

For your Schedule K-1 (1065) adjusted basis, I think you're getting confused between capital account and outside basis. They're different things! Your capital account can go negative (as yours has) but your basis can never go below zero. Since you got your interest as a bonus, your initial basis was probably the value included in your income. If that was zero, then your starting basis was zero. Since your basis starts at zero, you can't deduct any of the partnership losses now. They get suspended and carry forward until you get more basis (either by contributing money/property to the LLC or by the LLC generating income that's allocated to you). For the tax software, you're correct to enter zero as your starting basis if it was already zero last year. Make sure you track your suspended losses somewhere though - those are important for future years!

•Thanks for explaining the difference between capital account and outside basis! That clears up a lot. So even though my capital account shows -$7,900 at the end of this year, my outside basis is still just zero? Do I need to file any special forms to track these suspended losses or is it just something I need to remember for next year?

•Exactly right - your capital account can show -$7,900, but your outside basis remains at zero (it can't go negative). The difference between those numbers represents your suspended losses. There's no specific IRS form for tracking suspended losses - it's just something you need to maintain in your personal records. I recommend creating a simple spreadsheet that shows: 1) Your beginning basis each year 2) Increases to basis (contributions, income items) 3) Decreases to basis (distributions, loss items) 4) Ending basis 5) Cumulative suspended losses When you file next year, you'll need this information to know how much of any losses you can claim. If the partnership becomes profitable, those profits will increase your basis and allow you to start using those suspended losses.

Dealing with Schedule K-1 (1065) adjusted basis calculations can be a nightmare! I'm a partner in 3 different LLCs and finally figured out how to handle negative capital accounts. The key thing to understand: your adjusted basis and your capital account are calculated differently. Your capital account can go negative, but your tax basis cannot. When you receive a partnership interest as compensation (like you did), your initial basis equals the amount included in your income. If you didn't include any amount in income, your initial basis was zero. With a starting basis of zero and no additional contributions, you can't claim any of the $3,800 loss this year. But those losses aren't gone! They're suspended and can be used in future years when you have basis. For tax software, enter zero as your beginning basis, then show your share of loss, but the software should limit your loss deduction to zero.

•Are you sure about the suspended losses carrying forward indefinitely? I thought they expired after a certain number of years like net operating losses do. Can anyone confirm this?
