When applying for an EIN, what date should I use for 'Sole Proprietor Start Date' as a long-time tutor?
I've been tutoring for over a decade and I'm finally setting up a solo 401k (better late than never right?). The problem is that to set up the solo 401k, I need to get an EIN number from the IRS. When filling out the application, it's asking for a "Sole Proprietor Start Date" and I'm completely stuck on what to put. My tutoring timeline is kinda messy - I started working as an independent contractor for various tutoring companies about 12 years ago. Then about 4 years ago, I began taking on my own private students directly while still doing some work through the companies. So what date am I supposed to put? The date I first started tutoring as an independent contractor 12 years ago? Or when I started taking direct clients 4 years ago? Or something else entirely? I don't want to mess this up and have issues with the IRS later. Any advice would be really appreciated!

The "Sole Proprietor Start Date" the IRS is asking for is basically when you started your business. Since you've been operating as an independent contractor for tutoring companies for 12 years, that's when your sole proprietorship technically began. Even though you expanded to direct clients 4 years ago, you were still the same business entity from a tax perspective. As an independent contractor, you've been filing Schedule C with your personal tax returns all along, right? That's the key indicator that you've been operating as a sole proprietor. The IRS really just needs this information for their records. It won't affect your taxes or create any obligations. If you're unsure about the exact date you started 12 years ago, just use your best estimate - month and year is typically sufficient.

•This makes sense, but what if they haven't been filing Schedule C the whole time? Like what if they just reported it as "other income" or something in the earlier years before they knew better? Would that change anything about when their sole proprietorship officially started?

•If they reported income as "other income" instead of on Schedule C in earlier years, the IRS would still consider them as having business income, but they may not have been claiming all their business deductions properly. This doesn't change when the sole proprietorship started - it began when they first started performing services as an independent contractor and receiving income directly. Technically, any self-employment activity should be reported on Schedule C, even from the beginning. If they weren't doing this correctly in early years, it doesn't change the start date of their business - it just means they might not have been maximizing their tax benefits through proper business expense deductions.

I just went through this exact headache a few months ago! After spinning my wheels for days, I found this awesome tool at https://taxr.ai that helped me figure out my sole proprietor start date issue. I uploaded my old tax docs and it analyzed my income history to pinpoint exactly when I should consider my business started. What I learned is that your sole proprietorship actually began when you first started working as an independent contractor 12 years ago - even if you were doing it through companies. The key is that you weren't their employee, you were an independent contractor.

•How does this service actually work? Like do you have to give them all your financial info? I'm always skeptical about uploading my tax documents anywhere.

•Did it help with other tax questions too? I have a bunch of self-employment tax issues beyond just the EIN stuff that I need help figuring out.

•The service uses secure encryption for all document uploads, so your information stays protected. They use AI to analyze tax documents without storing sensitive details long-term. I was hesitant at first too, but their privacy policy reassured me. It absolutely helped with other tax questions! Besides solving my sole proprietor date issue, it answered questions about business deductions I could take and explained some 1099 confusion I had. You can actually ask it specific questions about your situation once it understands your tax profile.

Just wanted to follow up - I ended up trying taxr.ai after asking about it here. It was seriously helpful! Not only did it confirm I should use my original independent contractor start date (apparently that's what matters to the IRS), but it also found some home office deductions I missed from previous years. Now I'm thinking about filing an amended return based on what I learned. Way easier than the hours I spent searching through confusing IRS pages!

My accountant told me to put the date when I first began accepting money directly from clients, not when I worked through companies. But when I tried to call the IRS to confirm, I spent THREE HOURS on hold before giving up. Then a friend told me about https://claimyr.com which got me through to an actual IRS agent in under 20 minutes! They have this cool system that navigates the IRS phone tree and waits on hold for you, then calls you when an agent is on the line. You can see how it works at https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with said to use the date I first received income as an independent contractor, even if it was through companies. So in your case, that would be 12 years ago.

•Wait, there's a service that waits on hold with the IRS for you? That sounds too good to be true. Does it actually connect you with real IRS agents or just some third-party tax "experts"?

•I don't buy it. I've been trying to reach the IRS for weeks. No way some random service can magically get through when millions of people can't. Sounds like a scam to get your phone number.

•It connects you with actual IRS agents - the same ones you'd eventually reach if you stayed on hold yourself. The service just does the waiting for you. When an IRS agent picks up, they call you and connect the call. You're talking directly to official IRS staff, not third-party experts. I was skeptical too! But it's not a scam - they just use technology to navigate the phone system and queue your call efficiently. They don't ask for any tax info, just what department you need to reach. The service saved me literally hours of holding time, and I got my question answered by an official IRS representative.

I'm eating crow right now. After posting my skeptical comment, I got desperate enough to try Claimyr. I was honestly shocked when they called me back in about 35 minutes (I was quoted 45-60!). Got connected to an actual IRS agent who cleared up my sole proprietor question AND helped me with another issue I've been trying to resolve for months. For what it's worth, the agent confirmed what others here said - you should use the date you first started working as an independent contractor (12 years ago in your case), not when you started taking private clients directly. They said it's about when you first began earning self-employment income, regardless of whether it came through a company or directly from clients.

One thing nobody's mentioned - if you don't remember the exact date from 12 years ago, you can just use January 1st of that year. The IRS mainly needs the year correct, and they don't expect you to remember the exact day you started over a decade ago. That's what my tax preparer told me when I was in a similar situation. I had been doing freelance graphic design for years but couldn't remember exactly when I started. I put January 1, 2011 and had no issues getting my EIN.

•Do they verify this date against anything? Like are they going to check your tax records to make sure you reported income that year or something?

•They typically don't verify the exact date against your previous tax filings. The IRS uses this information primarily for their business records and classification. As long as you're reasonably accurate with the year, there's unlikely to be any issue. Even if they did check, they'd just see when you first reported self-employment income on your tax return. Remember though, if you're creating a solo 401k, your plan documents should be consistent with the date you provide to the IRS for your sole proprietorship.

Just wanted to add my experience - I went with the date I started taking direct clients instead of when I was contracting through agencies. My reasoning was that working for agencies felt different from my "real" business that I branded and marketed myself. The IRS accepted it no problem, and I got my EIN within minutes online. I've been using that EIN for my solo 401k for 3 years now with no issues.

•Thanks for sharing this perspective! It's interesting to see that either approach seems to work. I guess the takeaway is that the exact date isn't a make-or-break issue as long as you're reasonably accurate about when you began self-employment activities.

This is such a common confusion! I went through the exact same thing when I applied for my EIN last year. After reading through IRS Publication 583 and talking to a tax professional, here's what I learned: The "Sole Proprietor Start Date" should be when you first began operating as a business - which in your case would be 12 years ago when you started as an independent contractor. The IRS considers you to be in business from the moment you start providing services with the intent to make a profit, regardless of whether you're working through agencies or directly with clients. The key distinction is that as an independent contractor, you were never an employee of those tutoring companies - you were providing services as a business entity (sole proprietorship). When you expanded to direct clients 4 years ago, you didn't start a new business, you just grew your existing one. For what it's worth, I used January 1st of the year I started freelancing since I couldn't remember the exact date, and it was processed without any issues. The IRS really just needs this for their records - it won't create any retroactive obligations or problems for you. Good luck with your solo 401k setup!

•This is really helpful! I've been putting off getting my EIN for my freelance work because I was confused about this exact issue. Your explanation about being in business from the moment you start providing services with intent to make profit really clarifies things. I've been doing freelance web development through platforms like Upwork for about 3 years, so sounds like I should use that start date rather than when I got my first direct client last year. Thanks for mentioning Publication 583 too - I'll definitely check that out!

I actually just went through this same situation a few months ago! After dealing with the confusion and getting conflicting advice from different sources, I ended up calling the IRS directly (yes, it took forever on hold) and speaking with an agent who clarified this for me. The agent explained that your sole proprietorship began when you first started earning income as an independent contractor - so that would be 12 years ago in your case. Even though you were working through tutoring companies, you were still operating as a sole proprietor because you weren't their employee. The fact that you later expanded to direct clients doesn't change when your business actually started. What really helped me was looking at my old tax returns. If you were filing Schedule C or reporting self-employment income 12 years ago, that's your proof that you were already operating as a sole proprietor. If you can't remember the exact date, just use January 1st of that year - the IRS mainly cares about getting the year right. I used my original contractor start date from 8 years ago (even though I didn't start direct clients until 3 years ago) and got my EIN approved immediately. Been using it for my solo 401k ever since with no issues. You're going to love having that retirement account set up - better late than never is right!

•This is exactly the kind of real-world experience I was hoping to hear! It's reassuring to know that using the original contractor start date worked out fine for you. I'm definitely leaning toward the 12-year-ago date now based on all the responses here. Quick question though - when you called the IRS, did they mention anything about needing documentation to prove when you started? I'm a bit worried they might ask for records from way back then, and honestly my record-keeping wasn't great in those early years. Also, thanks for the encouragement about the solo 401k - I'm excited to finally get serious about retirement savings!
