How to file taxes for Multi-Member LLC after incorrectly filing EIN as Single-Member LLC?
My business partner and I started an LLC about 8 months ago and split everything right down the middle - 50/50. We've done everything together as equal partners - opened a business bank account, secured mortgages, purchased three commercial properties, and handled all business transactions with both of us clearly documented as equal owners of the company. The problem is that when we applied for our EIN, we accidentally checked the "single-member LLC" box and only put down my partner's name. Now we're getting ready to file our taxes and we've switched accountants. Our former accountant says we can just file as a partnership since that's what we actually are, but our new accountant is saying we need to make some kind of "election" with the IRS first to correct the mistake. I'm confused about what we need to do here. Can we simply file our taxes as a partnership since that's what we've been operating as? Or do we need to formally correct the EIN application first? Anyone dealt with this type of situation before?

This is actually a pretty common mistake. When you applied for your EIN as a single-member LLC but have been operating as a multi-member LLC, there's a discrepancy between your legal structure and how you reported to the IRS. Your new accountant is right - you need to file Form 8832 (Entity Classification Election) to properly classify your business as a partnership for tax purposes. The IRS allows you to change your classification, but you need to formally elect this change. Since you've been operating as a partnership all along, this is more of a correction than a change. If you don't file Form 8832 and just submit taxes as a partnership, there could be a mismatch in IRS records which might trigger questions later. The fact that all your business documents show two owners but your EIN application shows one owner creates inconsistency in your records.

•Thanks for the explanation! I have a similar situation but we've been operating for almost 2 years now. Is there a time limit on when you can file the Form 8832 to correct this kind of mistake? Will we face penalties for the previous tax year we already filed?

•There's generally a 3-year window for making a retroactive entity classification election, so you should still be within that timeframe for a business operating for 2 years. You'll need to submit a written statement explaining the reasonable cause for filing late with your Form 8832. For the previous tax year, if you already filed as a single-member LLC (disregarded entity) but operated as a partnership, you may need to file amended returns after making the classification election. The good news is that penalties are typically minimal or waived entirely when there's a reasonable cause for the correction, like a genuine misunderstanding of the filing requirements.

After struggling with almost the identical situation last year, I discovered taxr.ai (https://taxr.ai) and it saved me hours of confusion. My business partner and I had also checked the wrong box on our EIN application, and we were getting conflicting advice from different sources. I uploaded our LLC formation documents, business bank account paperwork, and EIN letter to taxr.ai, and their system analyzed everything and confirmed we needed to file Form 8832. They even generated a pre-filled form with the exact right codes and explanations for our situation. The best part was that they analyzed the operating agreement language we'd been using (which clearly showed a multi-member arrangement) and explained exactly how that factored into our tax filing. It definitely cleared up the confusion for us, and we were able to correct everything without hiring an expensive tax attorney.

•How long did the analysis take? I'm on a tight deadline before the next quarterly filing is due, and I need to get this fixed ASAP. Does the system just analyze documents or do they connect you with a human expert?

•I'm a bit skeptical about these tax tools. Did you still need your accountant to review everything, or were you able to file the Form 8832 yourself with just what they provided? And does it cover state tax implications too, or just federal?

•The analysis was completed in about 45 minutes. The system is AI-based so it works pretty quickly compared to waiting for a human tax professional to review everything. For urgent situations like yours, it's definitely faster than trying to book an appointment with a specialist. I ended up filing the Form 8832 myself using their instructions and pre-filled form. My accountant reviewed it but didn't need to make any changes. It definitely covered state tax implications too - it specifically explained how our state (California) treats different entity classifications and what additional forms we needed for state compliance after making the federal election.

Just wanted to follow up - I decided to try taxr.ai after being skeptical, and I'm genuinely impressed. I uploaded our operating agreement, bank statements showing both partners making capital contributions, and our incorrect EIN letter. The analysis not only confirmed we needed Form 8832, but it also found language in our operating agreement that could have caused issues even after fixing the EIN problem. The system suggested specific amendments to our operating agreement to better align with partnership tax treatment and explained how those would affect our tax obligations. It also identified deductions we were missing by operating incorrectly. The customized instructions were really detailed - definitely not generic advice. The whole process was much more thorough than I expected!

If you're struggling to get answers directly from the IRS about this EIN issue, you might want to try Claimyr (https://claimyr.com). I had been calling the IRS business line for weeks trying to confirm the right procedure for our misclassified LLC and kept hitting automated systems or 2+ hour wait times. I was skeptical at first, but after watching their demo (https://youtu.be/_kiP6q8DX5c), I decided to give it a try. The service called the IRS for me, navigated the phone tree, and got me connected to an actual IRS representative in about 30 minutes instead of the 3+ hours I was experiencing on my own. The IRS agent confirmed exactly what I needed to do to correct the EIN classification and explained the process step by step. It was such a relief to get an official answer directly from the IRS rather than trying to interpret conflicting advice from different accountants.

•How does this actually work? Do they just call for you and then transfer the call once they get through? I'm confused how they're able to get through faster than regular callers.

•This sounds too good to be true. The IRS wait times are horrendous for everyone. How could some random service possibly get through faster? Are they using some kind of corporate priority line or something? Seems sketchy to me.

•They use an automated system that continuously calls and navigates the IRS phone tree until it gets through. Once a representative answers, you get a call connecting you to that representative. You don't have to sit on hold for hours - they do that part for you. They don't have any special access or priority line - they're just using technology to handle the frustrating part of waiting on hold. Once you're connected, it's a direct conversation between you and the actual IRS representative, just like if you had called yourself and waited. The difference is you only join the call once there's a human ready to talk to you.

I need to admit I was wrong about Claimyr. After expressing my skepticism, I decided to try it for my LLC classification issue that was very similar to the original poster's problem. I was stuck in a loop where my accountant said one thing, online research suggested another, and I couldn't get through to the IRS for confirmation. Using Claimyr, I got connected to an IRS business tax specialist in about 45 minutes (after previously trying for days on my own). The agent explained that for my specific situation, I needed both Form 8832 AND a statement explaining the "reasonable cause" for the correction. They also told me which specific codes to use on the form based on my circumstances and confirmed I could avoid penalties if I filed within a certain timeframe. The information was much more detailed and specific to my situation than what I found online. Definitely worth it just for the peace of mind of having official IRS guidance.

Has anyone actually gone through an IRS audit with this kind of situation? We mistakenly filed as single-member for 2 years before correcting with Form 8832. Now I'm worried that the discrepancy might flag us for an audit. Our revenue jumped from $85K to $215K this year too, which I've heard can be an audit trigger.

•I went through this exact scenario and yes, we did get audited, but not because of the entity classification correction. The auditor actually told us that making a voluntary correction with Form 8832 is viewed positively. However, they did scrutinize our partnership allocations carefully since we had been inconsistent in prior years. Make sure your operating agreement clearly documents your 50/50 split and that your actual distributions match what you're reporting.

•That's really helpful to know - thank you! Were you able to prove the partnership allocations just with the operating agreement or did you need additional documentation? Our actual distributions weren't exactly 50/50 in practice because my partner took some draws for personal expenses.

Would filing Form 8832 affect how we handle self-employment taxes? Right now we're each paying self-employment tax on our respective shares, but I'm concerned changing our classification could impact how that works.

•Filing Form 8832 to properly classify as a partnership won't change your self-employment tax situation. As partners in a partnership, you'll still each pay self-employment taxes on your distributive shares of the partnership's ordinary business income, reported on Schedule K-1 and then transferred to your personal returns. The main difference is that you'll be filing a partnership return (Form 1065) with K-1s instead of having business income flow through on Schedule C of one partner's personal return. Both methods require paying self-employment tax, so the tax amount itself shouldn't change significantly if your income split remains the same.

•Thanks for clarifying! That makes sense. One more question - does the partnership return have a different filing deadline than individual returns? I want to make sure we get everything sorted in time.

•Yes, partnership returns (Form 1065) have a different deadline than individual returns. Partnership returns are due on March 15th (compared to April 15th for individual returns), but you can get an automatic 6-month extension by filing Form 7004, which would extend the deadline to September 15th. The earlier deadline exists because partnerships need to issue K-1s to partners so they can complete their individual tax returns by April 15th. Since you're correcting your classification mid-stream, I'd recommend filing for the extension to give yourself extra time to get everything properly sorted out, especially if you're dealing with amended returns from previous years.

I went through this exact situation last year with my business partner. We had also mistakenly filed our EIN as a single-member LLC when we were clearly operating as equal partners from day one. After researching extensively and consulting with a tax attorney, here's what we learned: Your new accountant is absolutely correct about needing to file Form 8832. The IRS requires this formal election to change your tax classification from a disregarded entity (single-member LLC) to a partnership. The key thing to understand is that even though you've been operating as a partnership in practice, the IRS only knows what you told them on your EIN application. Without Form 8832, there's a mismatch between your actual business structure and your tax classification that could cause problems down the road. We filed Form 8832 with a detailed explanation of our mistake, and it was processed without any issues. The form allows you to make the election retroactive to when you first started operating as a multi-member LLC, which should align your tax treatment with your actual business operations from the beginning. Don't try to just file partnership taxes without correcting the classification first - it will likely trigger correspondence from the IRS asking for clarification, which will delay your filing and potentially create more complications.

•This is really helpful advice! I'm dealing with the same situation right now. When you filed Form 8832 with the retroactive election, did you also have to file amended returns for previous years? And how detailed did your explanation letter need to be - did you just explain it was an honest mistake when applying for the EIN, or did you need to provide more documentation about your actual business operations?

•We didn't need to file amended returns for previous years since we made the election retroactive to our formation date. The IRS treated it as if we had been properly classified from the beginning, so our original tax filings were considered correct under the new classification. For the explanation letter, we kept it straightforward but included key details: we explained it was an honest mistake during the EIN application process, attached copies of our operating agreement showing the 50/50 partnership structure from day one, and included bank account documentation showing both partners making initial capital contributions. We also referenced specific business transactions (like property purchases) that clearly demonstrated multi-member operations from the start. The IRS accepted our reasonable cause explanation without requesting additional documentation. The key is showing that you genuinely operated as a partnership from the beginning and that the single-member classification was purely an administrative error, not an attempt to avoid taxes or misrepresent your business structure.
