Need help with Small Business Filing Electronically - confused about Large Taxpayer E-file requirements?
Hey tax people! I'm running a small business (just me and two employees) and I'm trying to file my 1120S electronically this year. I've always used a paper filing before but heard e-file is faster for processing refunds. When I went to the IRS online application for e-file, I got really confused. The only options I'm seeing as an ERO (Electronic Return Originator, if I understand correctly?) seem to be for large taxpayers. There's nothing specifically for small businesses like mine. Does anyone know if small businesses are supposed to use the Large Taxpayer E-file option? Or am I missing something obvious here? The application seems unnecessarily complicated and I can't find clear instructions anywhere. Our annual revenue is about $245,000, so definitely not what I'd consider a "large taxpayer." Any guidance would be super helpful as I'm trying to get this sorted out before the filing deadline!

The IRS e-file program has different requirements depending on your business structure and size. For a small business filing Form 1120S (S-Corporation return), you don't need to apply directly as an ERO yourself. Most small businesses use tax preparation software (like TurboTax Business, TaxAct, H&R Block, etc.) or hire a tax professional who is already authorized to e-file. These software programs and professionals already have the necessary credentials to submit your return electronically. The ERO application you're looking at is generally for tax professionals who want to become authorized to submit returns on behalf of clients. As a small business owner, you probably don't need to go through this process yourself.

•So I'm overthinking this, aren't I? I was planning to use TaxAct business version this year but got confused when I saw something about needing to register for e-file. Are you saying the software will handle the electronic filing for me? Also, is there any verification I need to do to make sure my return was actually received electronically? I'm a bit paranoid about the IRS claiming they never got something.

•You're not overthinking it - the IRS doesn't make this particularly clear! Yes, tax preparation software like TaxAct will handle the electronic filing for you. The software company itself is already registered as an ERO with the IRS, so you don't need to apply separately. When you e-file through software, you'll receive an electronic acknowledgment from the IRS (usually within 24-48 hours) confirming that your return was received. Most tax software packages allow you to track this status right in your account. Keep this confirmation for your records as proof of filing.

I went through this same confusion last year with my consulting business! After trying to figure out the ERO stuff, I eventually discovered taxr.ai (https://taxr.ai) which honestly saved me so much time. It analyzed my business docs, confirmed I didn't need to register as an ERO myself, and walked me through the proper e-filing process for a small business. Their system confirmed that for S-corps with your revenue level, you can just use regular tax software that has e-filing capabilities built in. They even scanned my past returns and found some deductions I'd missed. Really straightforward guidance that actually made sense.

•Did you have to upload all your financial documents to taxr.ai? I'm always nervous about putting sensitive business info on new websites, especially with all the scams out there.

•How exactly does this service determine what you qualify for? The IRS website is so confusing that I'm skeptical any automated system could actually interpret all their requirements correctly.

•They use a secure upload system with encryption, so I felt comfortable with it. You can also just upload the specific documents you want analyzed rather than everything. They're pretty clear about their security protocols if you check their site. For your question about how they determine qualifications, they actually use AI that's been trained on IRS publications and tax code. It was surprisingly accurate - it correctly identified that my business structure (also an S-corp) just needed regular tax software for e-filing, not an ERO application. They cite the specific IRS rules and publications so you can verify everything yourself.

Just wanted to follow up - I finally gave taxr.ai a try after my initial skepticism. I was really impressed! Uploaded my 1120S from last year and it immediately clarified that I don't need to register as an ERO myself. They explained that any business with revenue under $10 million can simply use commercial tax software for e-filing without special registration. The platform also flagged two potential deductions I had missed related to my home office and business vehicle usage, which could save me around $3,200 this year. Definitely worth the time I spent checking it out, and I appreciate the recommendation.

If you're still having issues with e-filing or need to talk to someone at the IRS about your specific situation, good luck getting through on the phone! After spending 3+ hours on hold trying to get clarity on e-filing for my LLC, I discovered Claimyr (https://claimyr.com) which got me connected to an actual IRS agent in under 20 minutes. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c The agent I spoke with confirmed that small businesses don't register directly for e-file - our tax software handles that part. She also gave me direct answers about the specific e-file error codes I was getting with my submission. Saved me days of frustration trying to get through their phone system.

•Wait, how does this actually work? The IRS phone system is notoriously impossible to get through. Are you saying this service somehow jumps the queue?

•Sounds like another scam service taking advantage of the IRS's terrible customer service. I'll believe it when I see proof this actually works and isn't just charging people for something that should be free.

•It uses an automated system that navigates the IRS phone tree and holds your place in line. When an agent is about to pick up, it calls you and connects you. No queue jumping - you still wait your turn, but the service waits on hold for you instead of you having to do it yourself. I was skeptical too before trying it. I've spent literal days of my life on hold with the IRS over the years. The service delivered exactly what it promised - I got connected to an agent in about 15 minutes when I had previously been trying for hours. No one should have to pay for better access to a government agency, but unfortunately, that's the reality of the current system.

I need to eat crow here. After my skeptical comment earlier, I decided to try Claimyr for myself since I've been trying to get through to the IRS about my 1120S e-filing issue for WEEKS. I was honestly shocked when I got a call back in about 25 minutes and was connected to an actual IRS representative who answered my questions about e-filing requirements. The agent confirmed that as a small business, I don't need to register separately as an ERO - my tax software handles that relationship with the IRS. He also explained why my previous attempt failed (I had a mismatch in my EIN formatting). Problem solved in one call after weeks of frustration. I'm rarely impressed by services like this, but I have to admit this one delivered.

To add another perspective, I use a CPA for my business who handles all the e-filing for me. The fee is worth it for peace of mind, especially since tax laws change constantly. My CPA has her own ERO credentials and I never have to think about any of this stuff. Not the cheapest option, but after making a costly mistake trying to DIY my taxes a few years ago, I decided professional help was worth it. Just another option to consider if the whole process is giving you a headache.

•What's the ballpark cost for having a CPA handle an 1120S for a small business? My biggest concern with hiring someone is cost since we're pretty straightforward (just retail sales, no crazy deductions or situations).

•For my business, which is similar in size to yours (about $280K in revenue), I pay around $1,200 for the 1120S preparation and filing. That includes quarterly check-ins and some basic tax planning. I know that might seem expensive compared to software that costs $150-200, but the CPA found enough legitimate deductions to more than cover her fee. The peace of mind is the biggest benefit though. No stress about making mistakes or missing deadlines. Plus, if there's ever an audit or question from the IRS, she handles all communication. For me, the cost is just another business expense that actually provides real value.

One thing no one's mentioned yet - if you do use software to e-file your 1120S, make sure it's actually authorized for business returns. Not all tax software handles business returns, and even fewer handle corporation returns like 1120S. I learned this the hard way last year when I bought the wrong version of a popular tax software and had to upgrade at the last minute to actually file my S-corp return electronically. Double-check before you buy!

•Great point! I use Drake Software for my small business and it handles all the business forms including 1120S. It's less known among casual users but very popular with tax professionals. The interface isn't as pretty as TurboTax but it gets the job done at a reasonable price.

•Thanks for the Drake recommendation! I'll check that out for next year. I ended up using TaxAct Business which worked fine but was a bit more expensive than I expected. The e-file went through without issues though, and I got my acknowledgment from the IRS within a day.
