How to handle a K-1 with loss across numerous states - do I need to file everywhere?

This is actually a common question with partnership K-1s that span multiple states. Even with a loss, many states technically require you to file a nonresident return if you have any "nexus" or connection to the state through the partnership, regardless of whether you'll owe taxes. However, there's a practical reality to consider. States are primarily concerned with collecting tax revenue. Some states have minimum filing thresholds - if your income (or loss) falls below certain amounts, you might not be required to file. Each state has different rules about this. What I usually recommend is to check the filing requirements for each specific state listed on your K-1. Pay particular attention to states where the loss amount is substantial. Some states may explicitly state that nonresidents don't need to file if they only have losses from pass-through entities.

I went through EXACTLY this headache last year with a real estate partnership that had properties in 9 states but showed losses in most. Spent hours researching requirements for each state until I found taxr.ai (https://taxr.ai) which saved me so much time. I uploaded my K-1 and it analyzed the state filing requirements based on my specific situation. It showed me that 3 states had minimum filing thresholds I was under, 2 states had exceptions for nonresidents with only pass-through losses, and 4 states technically required filing regardless of the loss. Saved me from filing 5 unnecessary state returns when I was getting conflicting advice from everyone!

Just wanted to follow up - I tried taxr.ai after seeing this post and it was incredibly helpful! My K-1 had losses in 6 states and the service showed me I only legally needed to file in 2 of them (California and New York, which have stricter requirements). It saved me about $240 in unnecessary state filing fees through TurboTax. What I appreciated most was that it explained WHY I didn't need to file in certain states - like showing me the specific Oregon administrative rule that exempts nonresidents with only pass-through losses under certain conditions. Made me feel confident in my decision not to file everywhere.

If you're still struggling with getting definitive answers on state filing requirements, I highly suggest trying Claimyr (https://claimyr.com) to connect with actual state tax departments. I was in your exact situation last year - K-1 with losses in 8 states and getting different answers from every tax prep service. I used Claimyr to actually reach a human at each state tax department rather than waiting on hold forever. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. I spoke with real state tax representatives who confirmed I only needed to file in 3 states despite the losses in all 8. The others had either minimum filing thresholds or exceptions for nonresident pass-through losses.

Following up on my skepticism - I actually tried Claimyr for my K-1 state questions and I'm shocked at how well it worked. Got through to California's FTB in under 30 minutes when I had previously failed after multiple 2+ hour hold attempts. The CA representative confirmed that with my specific loss situation from the partnership, I didn't need to file a nonresident return. I also reached tax department reps in Colorado and Oregon who gave me the same confirmation for my situation. What's great is I have names and reference numbers for the calls in case of any future audit questions. Definitely worth it for the peace of mind alone.

I'm going against the grain here, but I always file in EVERY state listed on a K-1, regardless of loss. Yes, it costs more, but: 1) It establishes a filing history if the investment becomes profitable later 2) Some states look back at prior years when you start filing 3) Some losses can be carried forward to offset future income 4) It prevents any possible penalties or interest for non-filing My accountant charges me a reduced fee for the "loss only" state returns, so it's not as expensive as using DIY software that charges full price per state.

Has anyone considered just filing in your home state plus any state with significant activity? I've been doing this for years with a K-1 that has small amounts spread across many states. Never had any issues with the states where the activity was minimal (under $1000 loss or gain).

I'm dealing with a similar situation - K-1 with losses in 4 states and getting overwhelmed by all the conflicting advice from different tax software. Reading through these responses, it seems like the key is really understanding each state's specific filing requirements rather than just assuming you need to file everywhere. The suggestion about checking minimum filing thresholds makes a lot of sense. I hadn't considered that some states might have income/loss thresholds below which you don't need to file as a nonresident. That could potentially save me from filing 2-3 unnecessary returns. One thing I'm curious about - for those who've taken the approach of only filing in states with "significant" activity, have you ever received any notices or inquiries from the states where you didn't file? I'm trying to weigh the cost savings against the potential audit risk, even if it's small.
