Started a single member LLC, really confused about form SS-4 line 9a selection
I just started my own single member LLC last month and I'm trying to fill out this Form SS-4 to get an EIN, but I'm stuck on line 9a. The instructions say something like "a domestic LLC with only one member is disregarded as an entity separate from its owner and must include all income and expenses on the owner's tax return." So does this mean I should be selecting "Sole Proprietor" on line 9a? That seems like the logical choice based on what I'm reading, but I'm really second-guessing myself. I don't think "Corporation" would be right here, but honestly I'm confused about the distinctions. What's making this more confusing is that I have a couple friends who told me they have LLCs but get taxed as S-Corps. I don't see that as an option on this form. Would I need to select "Other" and write something in manually? I'm worried about messing this up and causing problems with the IRS down the road. Any help would be appreciated!

Yes, for a newly formed single member LLC, you would select "Sole Proprietor" on line 9a of Form SS-4 when applying for an EIN. The IRS treats a single-member LLC as a "disregarded entity" by default, which means it's not considered separate from you for federal tax purposes. Your friends who have LLCs but are taxed as S-Corps have likely filed Form 8832 (Entity Classification Election) and/or Form 2553 (Election by a Small Business Corporation) after getting their EIN. This is a two-step process: first you get your EIN as a sole proprietor, then you make the election to be treated as an S-Corporation for tax purposes. The benefit of being taxed as an S-Corp comes later - it can potentially save you money on self-employment taxes once your business is generating significant profit. But for now, "Sole Proprietor" is the correct choice for your situation.

•So if I initially select Sole Proprietor when getting my EIN, but later decide I want to be taxed as an S-Corp, I can still make that change? How complicated is that process and when would be the right time to consider it?

•Yes, you can definitely make that change later. The process involves filing Form 8832 to elect to be treated as a corporation (though this step is technically optional in some cases) and then Form 2553 to elect S-Corporation treatment. The right time to consider it is usually when your business profit reaches a point where the self-employment tax savings outweigh the additional costs of running an S-Corp. Generally, many tax professionals suggest considering this when your business nets around $40,000-$60,000 in profit, but this varies based on your specific situation. S-Corps require more formalities like paying yourself a "reasonable salary," running payroll, and potentially higher accounting costs.

After struggling with the exact same form SS-4 confusion with my single member LLC, I finally found this amazing tool at https://taxr.ai that helped me sort everything out. I uploaded my LLC formation documents and tax questions, and it analyzed everything and explained exactly what I needed to select on line 9a (which was indeed "Sole Proprietor" in my case). The tool also explained the whole "LLC taxed as an S-Corp" thing that was confusing me too. Apparently that's a secondary step you can take later, and you don't need to worry about it on the initial SS-4 form. They showed me exactly what forms I'd need if I ever want to make that change in the future.

•Does this tool actually help with filling out the forms or just tells you what to do? I'm also setting up an LLC and honestly hate paperwork. Can it help with the whole EIN application process?

•I'm skeptical about tax tools - how accurate is this for complicated situations? I have rental property income I want to move into my new LLC structure and wondering if it handles that kind of complexity.

•The tool doesn't fill out the forms for you, but it gives you step-by-step guidance on exactly what to enter in each field. For my SS-4 form, it showed me screenshots with the correct options highlighted, which made it super simple to complete the EIN application on my own. For complex situations like rental properties in an LLC, it's actually designed to handle those specific scenarios. It analyzes your particular situation and provides customized advice. When I asked about potentially adding a second business activity later, it laid out all the tax implications and required forms for that specific scenario. Much more personalized than generic advice.

Just wanted to follow up about my experience with taxr.ai after being skeptical. I finally tried it with my complicated LLC/rental property situation, and it actually worked incredibly well! It confirmed I needed "Sole Proprietor" on line 9a of the SS-4 form, but then went further and showed me how my rental income would flow through on Schedule E rather than Schedule C (which I didn't know). The document analysis feature was surprisingly helpful - it caught issues with my Articles of Organization that might have caused problems down the road. It also showed me how to properly structure things now to make a potential S-Corp election easier in the future if my income keeps growing. Definitely saved me from making some mistakes on my SS-4 form.

If you're still struggling with your SS-4 form or have other IRS questions, I highly recommend using Claimyr (https://claimyr.com) to get connected directly to an IRS agent. I spent DAYS trying to get through on the regular IRS business line (800-829-4933) with no luck, but Claimyr got me through in about 20 minutes. The IRS agent I spoke with walked me through the exact right selection for my single member LLC on line 9a (which was "Sole Proprietor" as others have mentioned). She also explained when and how I could later change to S-Corp status if I wanted. You can see how the service works in this video: https://youtu.be/_kiP6q8DX5c - it saved me hours of frustration.

•How does this actually work? I've tried calling the IRS like 5 times and always get the "call volume too high" message and they hang up. Can this service really get through?

•Sounds like BS honestly. The IRS is impossible to reach. If this actually worked everyone would use it and the IRS would just shut it down. I'll stick to waiting on hold for 3 hours like everyone else.

•The service basically navigates the IRS phone tree for you and waits in the queue on your behalf. When they reach an agent, they call you, connect you, and then drop off the line - so it's just you talking directly with the IRS agent. It works because they have technology that can stay on hold indefinitely, unlike most of us who give up. I was skeptical too until I tried it. The difference is most people don't know about it, and it's not bypassing any IRS systems - it's just automating the hold process. I got clear answers about my SS-4 form and line 9a selection in one call instead of trying for days. The agent confirmed "Sole Proprietor" was correct for my single member LLC and explained the whole process clearly.

I need to eat my words. After my skeptical comment, I was still struggling with my SS-4 form for my LLC, so I broke down and tried Claimyr. Got through to the IRS in about 25 minutes after failing for TWO WEEKS on my own. The IRS agent confirmed that for my single member LLC, I absolutely should select "Sole Proprietor" on line 9a. She also explained that the S-Corp election is a completely separate process that happens after getting my EIN. The agent walked me through several other questions I had about the form that I'd been stuck on. Honestly can't believe how easy it was compared to the hours I wasted trying to call them directly. Wish I'd done this two weeks ago when I first got stuck on the form SS-4.

Another option worth mentioning is that some tax professionals will help you complete Form SS-4 for a relatively small fee. When I started my single member LLC last year, I paid my accountant $75 to handle the EIN application. She selected "Sole Proprietor" on line 9a since that's the default for single member LLCs. Later on, once my business was more established, she helped me file the paperwork to be taxed as an S-Corporation, which was separate from the initial EIN application process. The cost savings on self-employment tax have been substantial, but it only made sense once my business income reached about $50K.

•Did your accountant also help with all the extra S-Corp requirements? I've heard you need to run payroll and pay yourself a "reasonable salary" which sounds complicated. How much extra work/cost is involved with that part?

•Yes, my accountant handles all the S-Corp requirements including setting up payroll and determining a reasonable salary. It does add some complexity and additional costs - I pay about $600 per quarter for payroll processing and accounting services related to the S-Corp, plus there are additional tax forms to file. The extra costs are worth it in my case because I'm saving approximately $7,500 annually in self-employment taxes. However, this math only works when your business is generating enough profit. Below a certain income threshold, the extra costs and administrative burden of an S-Corp can outweigh the tax benefits.

Just to add another data point - I selected "Sole Proprietor" on line 9a of Form SS-4 for my single member LLC last year and it was definitely the right choice. The IRS processed my application without any issues. One thing to be aware of - when you get your EIN as a single-member LLC (selecting "Sole Proprietor"), you'll file your business taxes on Schedule C of your personal return. You don't file a separate business return like you would with an S-Corp or partnership. That was confusing to me at first because I thought having an LLC meant filing a separate business return.

•Do you still get liability protection with the LLC even though it's treated as a sole prop for taxes? That's what's confusing me about this whole process.

•Yes, you absolutely still get the liability protection from the LLC even though it's taxed as a sole proprietorship! The tax treatment and legal protection are two separate things. The LLC structure provides legal separation between your personal assets and business liabilities, which is one of the main reasons people form LLCs in the first place. The "disregarded entity" status only applies to federal taxes - it doesn't affect the legal protections. So you get the best of both worlds: simple tax filing (Schedule C on your personal return) plus the liability shield of the LLC structure. Just make sure you maintain proper corporate formalities like keeping business and personal finances separate to preserve that protection.
