2018 NOL Carryforward Rules - Need Simple Explanation for S-Corp Losses
I'm seriously behind on filing my 2021 S-corporation and personal returns. Trying to get caught up but these NOL (Net Operating Loss) rules have me completely confused. For my 2020 S-corp returns, there was a loss of around $11K. This loss flows through to my 2020 1040 via K1, and I didn't have any W2 income that year. My Schedule 1 shows this loss with a small adjustment for some canceled debt. Since I'm filing extremely late (I know, I know), can I carry forward the 2020 loss to my 2021 return? I don't actually want to use it in 2021, just note it as carried forward. Would I have needed to make some special election on a different schedule (like Schedule D maybe?) to make the 2020 loss eligible for carryforward in the first place? And what if I have another loss for 2021 - can I combine both losses and designate the total to be carried forward? Sorry if this is confusing - I'm typing this at 3am after staring at tax forms all night. Would really appreciate if someone could explain this in simple terms. Getting overwhelmed with all these tax rules!

The good news is that NOLs from S-corporations are actually pretty straightforward once you understand how they work. The loss flows through to your personal return via the K-1, as you mentioned. For tax years 2018 and later (which includes your 2020 loss), NOLs can be carried forward indefinitely. You don't need to make any special election on your original return to carry the loss forward - it happens automatically if you can't use it. The TCJA (Tax Cuts and Jobs Act) changed these rules. The only limitation is that NOLs arising in tax years after 2017 can only offset up to 80% of your taxable income in future years. So if you have income in 2021, you can offset up to 80% of that income with your 2020 NOL. And yes, if you have another loss in 2021, both losses can be carried forward together. You'll need to keep track of each year's loss separately though, since they'll be used in order (oldest first).

•Thanks for this explanation, but I'm still a bit confused. Where exactly on my 2021 return would I note this carryforward? Is there a specific form or line? And what if my S-corp was dissolved in early 2022 - does that affect my ability to use these losses?

•You'll report your NOL carryforward on Form 1040, Schedule 1, line 8 "Other Income" and write "NOL" next to it. You should also attach a statement showing how you calculated the NOL carryforward amount. Dissolving your S-corporation doesn't affect your ability to use the losses that have already passed through to you. Once the loss is on your personal return, it's yours to use regardless of what happens to the S-corp later. The losses stay with you as the individual taxpayer, not with the business entity.

After dealing with a similar situation last year, I found this amazing tool at https://taxr.ai that helped me figure out my NOL situation. I had a couple years of S-corp losses that I needed to track and the contradicting advice I was getting from different accountants was making my head spin. Their system analyzed my previous returns and actually found that I had calculated my NOL carryforward incorrectly. It showed me exactly where on my return the loss should be reported and how to document it properly. The detailed explanation they provided made it super clear how to handle the losses going forward.

•Does taxr.ai work for partnerships too? I have a similar situation but with a partnership K-1 showing losses. And how accurate is it compared to having a CPA review your returns?

•I've been burned by online tax tools before that claim to handle complex situations but then don't actually work for S-corps. Does it really understand the passive loss limitations and basis issues that come with S-corp losses? Those can get complicated fast.

•Yes, it absolutely works for partnerships too. It handles K-1s from partnerships, S-corps, and even estates and trusts. The system is specifically designed to interpret those forms and apply the correct tax rules. As for accuracy, I found it incredibly detailed - more thorough than my previous CPA honestly. It flagged issues my accountant missed related to basis limitations and passive activity rules. The tool specifically looks for these complex scenarios and explains them in plain language.

I was really skeptical about using an AI tool for something as complex as NOL carryforwards, but I gave https://taxr.ai a try after seeing it mentioned here. Wow - what a difference! My situation was similar with multiple years of S-corp losses that I needed to properly track. Not only did it correctly identify how to carry forward my losses, but it also caught that I had been incorrectly calculating my basis in my S-corp, which was limiting how much of my losses I could actually deduct. They provided a detailed basis worksheet showing exactly how to track everything year by year. This literally saved me thousands in potential audit adjustments.

I had the worst time trying to get someone at the IRS to explain NOL rules to me. Spent HOURS on hold and kept getting disconnected. Finally used https://claimyr.com to get through to an actual person at the IRS. You can see how it works here: https://youtu.be/_kiP6q8DX5c The service got me connected to an IRS agent in about 20 minutes when I had been trying for days on my own. The agent walked me through exactly how to report my NOL carryforward and what documentation I needed to include with my return. Totally worth it for the peace of mind knowing I'm doing it correctly.

•I don't understand how this would work better than just calling the IRS yourself. Aren't they just calling the same number everyone else is? And are you sure the advice from random IRS phone agents is reliable for something complicated like NOLs?

•The service doesn't cost much at all compared to the time you save - I don't remember the exact amount but it was very reasonable. They have some technology that navigates the IRS phone system and holds your place in line, then calls you when they have an agent on the line. You're right that they're calling the same IRS number, but the difference is you don't have to sit on hold for hours. The system does that for you, and you only get on the phone when there's actually an agent ready to talk. As for reliability of advice, the agent I spoke with was in the business tax department and extremely knowledgeable about S-corps and NOLs specifically.

I was extremely dubious about this Claimyr service - it seemed like a scam that couldn't possibly work. My accountant was on vacation and I had a pressing question about NOL documentation that needed answering before filing. After wasting an entire afternoon trying to get through to the IRS myself, I reluctantly gave it a shot. I'm actually shocked to say it worked perfectly! Within 45 minutes I was speaking with an IRS representative who specialized in business returns. They confirmed exactly how to document my NOL carryforwards and what supporting schedules I needed. They even emailed me the relevant IRS publication sections afterward. Saved me days of stress and uncertainty.

Just to add another perspective here - NOL carryforwards from S-corps have some additional complexities people often miss. Remember that your ability to deduct the loss is limited by: 1) Your basis in the S-corp 2) At-risk limitations 3) Passive activity loss rules Without sufficient basis, you can't take the loss even if it flows through on the K-1. If your S-corp had debt that you personally guaranteed, that can increase your basis and allow more loss deduction.

•Thanks for bringing this up - I hadn't considered the basis limitations! Any simple way to calculate my basis? I've had the S-corp for about 5 years, started with $5K initial investment, and have been putting in some money each year to cover expenses (around $15K total over the years). Never taken any distributions.

•Your basis starts with your initial investment ($5K) and increases by any additional capital contributions ($15K) and any income that was reported to you on K-1s over the years. It decreases by losses and any distributions you took. So if you never took distributions, your basis would be $5K + $15K + any income reported on K-1s from previous years - any losses from previous years. You'll need to look at all your old K-1s to track this properly. If your basis went to zero in a previous year, any excess losses would be suspended and carried forward until you have basis again. This is separate from the NOL rules and often catches people by surprise.

Has anyone used TurboTax for handling NOL carryforwards from an S-corp? I'm in a similar situation and wondering if it can handle this correctly or if I need to go to a CPA.

•I tried using TurboTax for my S-corp NOL last year and it was a nightmare. It kept asking me questions that didn't make sense for an S-corp, and I don't think it properly tracked my basis. I ended up paying a CPA to fix everything and it cost me way more than if I'd just gone to them in the first place.
