SMLLC S-corp 1120s refund confusion - first year filing mistakes
Just wrapped up my first year running my business as a single member LLC elected to be taxed as an S-corporation. I've been diligently paying my payroll and federal withholding taxes through the EFTPS website using Form 941 with my EIN number. I thought I was doing everything by the book. Well, surprise surprise! After filing my 1120S through TurboTax, it looks like I'm getting a refund for everything I paid in. Apparently, since my business is a disregarded entity, I was supposed to be making these payments via Form 1040 with my SSN instead of my EIN. Lesson learned, although it's gonna cost me some fees. My first concern is about reporting on Form 941. I've been playing around with the form on the EFTPS site, but I can't figure out how to report the FICA and federal withholding taxes without including an actual payment. If Form 941 is just for reporting purposes for a disregarded entity, how exactly am I supposed to provide the IRS with my income information to show I'm compliant? Also confused about TurboTax and how to report the various taxes I've already paid. In the software, there's a section for entering this information, but I'm not sure if I should be including these payments since they were made incorrectly with my EIN rather than my SSN. Does anyone have experience with this situation?

This is a common misunderstanding with single-member LLCs that elect S-corporation status. Let me clarify a few things: First, a single-member LLC that elects to be taxed as an S-corporation is NOT a disregarded entity. Once you make the S-corp election, your business is treated as a corporation for tax purposes. So you were actually correct to use Form 941 with your EIN for payroll taxes. The confusion might be coming from the difference between income taxes and employment taxes. For employment taxes (Social Security, Medicare, federal income tax withholding), you should be using Form 941 with your EIN. This is separate from your personal income taxes. If TurboTax is showing a refund, I'd double-check that you've properly entered all your payroll information. Sometimes the software misinterprets S-corp data, especially in your first year. Make sure you've correctly reported your salary as an employee of the S-corp on your personal return as well.

•Wait, but I thought single member LLCs are always disregarded entities by default unless you elect otherwise? I'm getting ready to start my own consulting business and was planning to go the SMLLC route with S election. Now I'm confused about which forms I should be using.

•A single-member LLC is indeed a disregarded entity by default for federal tax purposes. However, once you make the election to be taxed as an S-corporation (by filing Form 2553), you're no longer treated as a disregarded entity - you're treated as a corporation. When you elect S-corp status, you need to file Form 941 quarterly with your EIN to report employment taxes for yourself as an employee. You'll also need to file Form 1120S (the S-corporation return) annually. Your personal income from the business comes in the form of wages (reported on W-2) and distributions (reported on Schedule K-1), which then get reported on your personal 1040.

I went through this exact nightmare last year and discovered https://taxr.ai was an absolute lifesaver. I was also confused about SMLLC S-corp filing requirements and kept getting conflicting advice from different sources. What helped me was uploading my docs to the taxr.ai system - it analyzed everything and pinpointed exactly where my confusion was coming from. In my case, I had properly filed the 941s but messed up how I was reporting it on my 1120S. The AI caught that I was double-counting certain payments and explained how the payroll taxes and income taxes interact for S-corps. Their explanations were way clearer than what my accountant told me.

•Did you have to provide sensitive info like your SSN? I'm skeptical about uploading tax docs to random websites. Also, how detailed was their analysis for specific S-corp issues? My situation has some weird quirks with owner's health insurance that I'm trying to figure out.

•I'm curious - did it help with amended returns? I think I've been making the same mistake for the past two years with my SMLLC S-corp and might need to fix previous filings. Was it clear about what forms needed correction?

•You only need to upload the specific tax forms or documents you want analyzed - I just uploaded my 941s and 1120S draft without any SSNs visible (I redacted those). The analysis is impressively detailed for S-corp issues - it actually explained the difference between reasonable compensation requirements and distributions, which helped me understand why certain payments were being treated differently. For amended returns, yes! That was actually the most helpful part. It identified exactly which lines on my previous 1120S were incorrect and provided a detailed explanation of how to complete Form 1120X for the amendment. It also calculated the potential tax impact so I could decide if it was worth amending.

Just wanted to follow up - I tried taxr.ai last week after seeing this post, and it was exactly what I needed! I uploaded my botched 1120S and 941s, and within minutes it identified that I had been incorrectly reporting my officer compensation. The analysis showed me precisely which boxes on my 1120S were wrong and how it affected my K-1. What impressed me most was how it explained the relationship between the 941 deposits and the credit on the 1120S - something none of the articles I read online made clear. It also generated a checklist for fixing my previous year's return that I could send directly to my accountant. Saved me hours of research and probably thousands in incorrect tax payments!

If you're getting a refund from the IRS because of this confusion, be prepared to wait FOREVER. I made a similar mistake with my S-corp last year, and it took 8 months to get my refund. Tried calling the IRS business line over 20 times and could never get through. Finally discovered https://claimyr.com and their YouTube demo at https://youtu.be/_kiP6q8DX5c - they got me connected to an actual IRS agent in under 30 minutes when I'd been trying for weeks. The agent was able to look up my refund status and tell me exactly what was causing the delay (they needed verification of my S-election date). Completely worth it to skip the hold times and actually talk to someone who could fix the issue. My refund was processed within 2 weeks after that call.

•How does this service actually work? The IRS phone system is basically designed to make you give up. Do they have some special back channel to get through?

•Sounds like a scam. No way they can get you through to the IRS faster than anyone else. The IRS has one phone number and everyone waits in the same queue. I bet they just charge you and then you still end up waiting.

•The service uses some kind of automated system that navigates the IRS phone tree and waits on hold for you. When they finally get through to an agent, you get a call back and are connected immediately. They basically do the waiting part for you. They don't have a "back channel" - they're just using technology to handle the most frustrating part of the process. Once you're connected, you're talking to the same IRS agents anyone else would talk to, but without spending hours of your own time on hold.

I need to eat my words from my previous comment. After my frustration hit a breaking point trying to get info about my business tax situation, I tried Claimyr yesterday. Totally expected it to be BS, but I was desperate after trying to call the IRS for THREE WEEKS with no success. To my genuine shock, I got a call back in about 45 minutes saying they had an IRS agent on the line. The agent was able to confirm that my S-corp election was properly processed and that my refund was approved but stuck in review. She even gave me a specific timeframe for when to expect the deposit. For anyone dealing with S-corp refund delays like the original poster - don't waste weeks of your life trying to call. This seriously saved me so much time and frustration.

Just to add another perspective - make sure you're paying yourself a "reasonable salary" as an S-corp owner. This is the #1 thing the IRS looks at with S-corps. If your business made $100k but you only paid yourself $20k in salary (with the rest as distributions), that's a red flag. The IRS wants their FICA taxes, and if they think you're underreporting your salary to avoid them, that can trigger an audit. Especially if you're getting refunds, they may look more closely at your filings.

•What's considered "reasonable" tho? Is there like a percentage of business income that's the standard? I've heard everything from 30% to 60% of profits should be salary.

•There's no fixed percentage that's automatically considered "reasonable" - it depends on your industry, role, qualifications, and what similar positions would pay in your area. A good starting point is to research what someone would earn doing your job in your location if they weren't the owner. Sites like Bureau of Labor Statistics or industry salary surveys can help establish this baseline. Some tax professionals suggest that anything less than 40-50% of your business profits as salary might raise eyebrows, but it really depends on your specific situation.

Has anyone here used both TurboTax and H&R Block for S-corp returns? I'm having similar issues with TurboTax and wondering if H&R Block handles single-member LLC S-corps better. The TurboTax interface seems super confusing for this specific situation.

•I switched from TurboTax to H&R Block last yr for my s-corp and it was WAY better. TurboTax kept giving me errors about my 941 payments but H&R Block had a specific section for SMLLC S-corps. The questions were clearer and it properly showed how the salary and distributions flow between the 1120S and 1040.
