NOL carryforward for single member LLC - am I misunderstanding how this works?
I have a single member LLC that's treated as a disregarded entity for tax purposes, and I'm trying to wrap my head around how NOL (Net Operating Loss) carryforwards work when I also have W-2 income from my day job. From what I understand, in the first year when my LLC has a loss, that NOL reduces my overall tax liability by offsetting some of my W-2 income. Then in the following year, assuming my LLC actually turns a profit, I can use the remaining NOL carryforward to reduce my tax liability again. This seems like I'm getting a double benefit - first reducing taxes on my regular income, then reducing taxes on my business income the next year. Am I understanding this correctly? It seems oddly generous compared to other tax rules I've encountered.

You're close, but not quite understanding how NOL carryforwards work. An NOL only gets used once, but it can be applied across multiple tax years depending on when you need it. Here's how it works: When your LLC has a loss in Year 1, that loss can offset other income (like your W-2 income) in that same tax year. If the loss is larger than your other income, then you have a "Net Operating Loss" that can be carried forward to future years. In Year 2, you don't get to "double dip" with the same loss. You only carry forward whatever portion of the loss that couldn't be used in Year 1. For example, if your LLC lost $20,000 in Year 1, but you only had $15,000 in W-2 income, you'd have $5,000 of NOL to carry forward to Year 2. Does that make more sense now? It's not about getting two tax benefits from the same dollar of loss - it's about being able to spread a large loss across multiple tax years.

•Thanks for the explanation, but I'm still confused about something. If I had a $20,000 loss from my LLC but $60,000 in W-2 income in Year 1, wouldn't all of my loss be used up that year? When would I actually have an NOL to carry forward? Also, does having a single-member LLC vs a partnership make any difference for NOL purposes?

•In your example, if you had a $20,000 LLC loss and $60,000 in W-2 income in Year 1, you're correct - the entire loss would be used in Year 1 to offset part of your W-2 income, and you wouldn't have any NOL to carry forward to future years. An NOL carryforward only happens when your total losses exceed your total income in a given tax year. For example, if your LLC lost $70,000 but you only had $60,000 in W-2 income, you'd have a $10,000 NOL to carry forward. As for your second question, the entity type does matter. With a single-member LLC (disregarded entity), the losses flow directly to your personal return. With a partnership, the losses flow through to the partners' personal returns based on their ownership percentages, but partnership losses might be limited by basis, at-risk rules, and passive activity rules.

I went through this exact situation last year with my consulting business (also a single-member LLC). I spent hours trying to figure it out until I found https://taxr.ai which analyzed my previous returns and helped me understand my specific NOL situation. The confusing part for me was that the rules for NOLs changed with the Tax Cuts and Jobs Act and then again with the CARES Act. Before 2018, you could carry losses back or forward, but now it's generally forward only. Also, post-2020, you can only use NOLs to offset up to 80% of your taxable income in any future year. The tool helped me determine exactly how much of my NOL I could use each year and how to properly document it all. Saved me a ton of stress when tracking these carryforwards through multiple tax years.

•How exactly does taxr.ai work with this kind of situation? I'm self-employed with an LLC and had a rough 2023 with some big losses, but I'm expecting to be profitable in 2024. Do they help with calculating the carryforward amount or just explaining the concept?

•Is taxr.ai worth it compared to just asking my regular accountant? I've had mixed experiences with online tax tools - seems like they miss nuances specific to my situation. Does it handle state NOL rules too? Those can be completely different from federal.

•It analyzes your tax documents and transcripts to identify your specific NOL situation. In my case, it looked at my Schedule C losses and calculated exactly how much NOL I had available to carry forward based on my specific numbers, not just general concepts. For state NOL rules, yes it does handle those too. That was actually the most valuable part for me - each state has different conformity with federal NOL rules. Some states don't allow carryforwards at all, while others allow different carryforward periods or percentages than the federal rules.

Just wanted to update after trying taxr.ai for my NOL situation. It was actually really helpful! I uploaded my past returns and it analyzed my specific business losses from 2023. The tool showed me that I had been misunderstanding how the 80% limitation applies - I thought it meant I could only carry forward 80% of my loss, but it actually means I can only offset up to 80% of my income in future years with the NOL. This makes a huge difference in my tax planning for 2024-2025. It also flagged that my state (California) has different NOL rules than federal, which I had no idea about. Definitely recommend if you're dealing with business losses and carryforwards.

For anyone dealing with IRS questions about NOLs or trying to verify their NOL calculations, I strongly recommend using https://claimyr.com to get through to an IRS agent quickly. I spent weeks trying to reach someone at the IRS to confirm I was handling my LLC's NOL correctly. After trying for days with busy signals and disconnects, I used Claimyr and got through to an IRS representative in about 20 minutes. They verified my NOL calculations and answered my specific questions about how to document the carryforward on my Schedule C for the next year. You can see how it works here: https://youtu.be/_kiP6q8DX5c When you're dealing with something complex like NOLs that can affect multiple tax years, having that direct confirmation from the IRS gives so much peace of mind.

•Wait, this actually works? I thought it was impossible to get anyone on the phone at the IRS. How much does this service cost? And do they actually connect you with IRS agents who understand complex issues like NOL carryforwards for pass-through entities?

•This sounds like a scam. The IRS phone system is deliberately designed to be impenetrable. What magic do they supposedly use to get through when millions of people and even tax professionals can't? I'll believe it when I see it.

•The service works by using technology to navigate the IRS phone system and waiting on hold so you don't have to. When an agent actually picks up, they call your phone and connect you directly to that agent. It's like having someone wait in line for you. Regarding the second question about IRS agent knowledge - it can vary. I was connected with someone in the business tax department who was familiar with NOLs. If you get someone who doesn't understand your specific issue, you can always ask to be transferred to a specialist or call back. The benefit is that you're actually speaking with someone instead of never getting through at all.

I have to admit I was completely wrong about Claimyr. After my skeptical comment, I decided to try it as a last resort because I needed clarification on my NOL carryforward calculation before filing my extended return. Not only did I get through to the IRS (first time in 3+ attempts on my own), but I was connected to an agent who actually specializes in business tax issues. She walked me through exactly how to properly document my LLC's NOL on both my current return and how to track it for future years. For anyone struggling with NOL questions, getting direct confirmation from the IRS is priceless. They verified that my accountant had calculated things correctly but had missed documenting the carryforward properly on my forms.

Don't forget that state treatment of NOLs can be wildly different from federal! My LLC had a federal NOL that I carried forward properly, but I completely missed that my state (Illinois) had different rules about how much I could use each year. Ended up having to amend my state return and pay additional tax plus interest. Make sure you research both federal AND state rules for your specific situation.

•Do you know if there's a good resource that compares all the different state NOL rules? I have income in multiple states through my LLC and trying to figure out each state's rules individually is making my head spin.

•I don't know of a single comprehensive resource that covers all states' NOL rules in one place. The most reliable approach I found was to go directly to each state's department of revenue website. Most states have tax bulletins or publications specifically addressing NOLs and how they conform (or don't conform) to federal treatment. The variations can be significant - some states limit carryforward periods to 5 or 10 years while federal is indefinite, some don't recognize NOLs at all, and others have special limitations based on your business type or income level.

One thing I haven't seen mentioned yet is that you need to keep REALLY good records of your NOL and how much you use each year. The IRS doesn't track this for you! I learned this the hard way when I got audited for tax year 2022. I had an NOL from 2021 that I carried forward, but I couldn't immediately produce documentation showing how I calculated it. Had to go back through all my records and reconstruct everything, which was a huge headache.

•What kind of documentation did the IRS want to see specifically? Did you need to create your own spreadsheet or is there an official form for tracking NOL carryforwards from year to year?

•The IRS didn't require a specific form for tracking the NOL carryforward, but they wanted to see how I calculated the original loss and how much I had used in each subsequent year. I ended up creating a simple spreadsheet showing the original NOL amount, how much I used each year, and the remaining balance. I also included copies of the relevant schedules from each year's tax return (Schedule C showing the business loss, Form 1040 showing the NOL deduction, etc.). The agent seemed satisfied with this approach. What made it complicated was that I had to show not just the NOL itself but also demonstrate that I had basis in my LLC to claim the loss in the first place. This is where good bookkeeping really pays off!

This is such a helpful thread! I'm dealing with a similar situation where my single-member LLC had losses in 2023 but I'm expecting profits in 2024. One thing that's been confusing me is the interaction between NOL carryforwards and the QBI (Qualified Business Income) deduction. If I use my NOL carryforward to offset business income in 2024, does that reduce my QBI deduction for that year? It seems like the NOL would reduce my taxable business income, which would then reduce the amount eligible for the 20% QBI deduction. Has anyone navigated this combination of NOL carryforward and QBI? I'm trying to figure out if there's an optimal strategy for timing the use of my NOL to maximize both benefits.

•Great question about the NOL and QBI interaction! You're absolutely right that this creates a potential conflict between maximizing current tax savings and preserving future QBI benefits. When you use NOL carryforward to offset business income, it does reduce the income that's eligible for the QBI deduction. So if you have $50,000 in business income in 2024 and use $20,000 of NOL carryforward, you'd only have $30,000 eligible for the 20% QBI deduction instead of the full $50,000. One strategy some people use is to only utilize enough NOL each year to stay within lower tax brackets, preserving both the remaining NOL for future years and maximizing QBI on the income they do report. Since NOL carryforwards are now indefinite (post-2017), you have flexibility in timing. Have you run the numbers both ways to see which approach gives you better long-term tax savings? The optimal strategy really depends on your expected income trajectory and tax bracket projections for the next few years.

This is exactly the kind of complex tax situation where having multiple moving pieces can create unexpected interactions. The NOL/QBI timing question is particularly tricky because you're essentially choosing between immediate tax relief and future deduction optimization. One approach I'd suggest is creating a multi-year projection model. Map out different scenarios: using all available NOL immediately vs. spreading it over several years to preserve QBI benefits. Don't forget to factor in potential changes to your business income, other income sources, and even possible changes to tax law. Also consider that the QBI deduction has income limitations (phases out completely at $364,200 for single filers in 2024), so if you expect your income to grow significantly, it might make sense to maximize QBI in earlier years when you're still under those thresholds. The 80% limitation on NOL usage gives you some natural spreading anyway - you can't use NOL to offset more than 80% of your taxable income in any given year. This might actually work in your favor for preserving some QBI benefit even when using carryforwards. Have you considered consulting with a tax professional who specializes in business taxation? This kind of multi-year strategic planning is where their expertise really pays off.

•This is really valuable advice about creating a multi-year projection model! As someone new to dealing with NOLs, I hadn't considered how the 80% limitation might actually help preserve some QBI benefits. One thing I'm wondering about - when you mention the QBI phase-out thresholds, does that apply to the business income before or after NOL adjustments? If my gross business income puts me over the threshold but my net income (after NOL carryforward) brings me back under, which number determines my QBI eligibility? Also, for those who've worked with tax professionals on this kind of strategic planning, roughly how much should I budget for that level of analysis? I want to make sure the cost of the advice doesn't eat up the potential tax savings!
