Did I file correctly for my S-Corp LLC on my 1040? First-time self-filer confused
I'm stressing out that I might have messed up my tax filing this year. This is my second year with my S-Corp LLC (formed in 2021), but my first time trying to do the business taxes myself. Last year I had a professional handle everything, including my personal 1040 return. Since I was trying to save money, I searched for online business tax filing options and clicked on a FreeTaxUSA ad that seemed to indicate they do business returns. I set up an account with my business information, but then it immediately started asking for personal details. To complicate things, I just got married in October, so this is also my first time filing married jointly. I started getting concerned that I might be filing personal taxes when I should be doing business taxes first, but after trying to research more online, I kept going. I completed everything, but now I'm having serious doubts about whether I filed correctly. Did I need to file a separate business return (Form 1120S) before doing my personal 1040? FreeTaxUSA seemed to incorporate some business income questions, but I'm worried I missed something major. Has anyone dealt with this situation before? I really don't want to get hit with penalties for filing incorrectly.

You're right to question this. As an S-Corp owner, you actually need to file two separate returns: Form 1120S for your S-Corporation and then your personal Form 1040 that includes the income passed through from your business. FreeTaxUSA is primarily designed for personal returns. While it can handle Schedule C for sole proprietors, it doesn't support Form 1120S for S-Corporations. The business itself needs to file its own tax return first, which then generates a Schedule K-1 that reports your share of the business income/losses. That K-1 information then gets reported on your personal 1040. Since you've already filed your personal return without properly filing the S-Corp return first, you'll need to address this. You should look into business tax software like TaxAct Business or hire a professional again for the S-Corp filing, then likely file an amended personal return once you have the correct K-1 information.

•Thanks for the info. So I definitely messed up then. Do you know if there's a penalty for filing in the wrong order? Should I contact the IRS directly or just file the 1120S now and then amend my personal return?

•The S-Corporation return was actually due on March 15th (unlike personal returns due April 15th), so you're already past that deadline. Late filing penalties for S-Corps are $210 per month per shareholder for up to 12 months. I'd recommend filing the S-Corp return as soon as possible to minimize these penalties. After that's done and you have your K-1, you should file an amended personal return (Form 1040X) to correctly report your business income. It's better to address this proactively rather than waiting for the IRS to catch it. If you explain the situation, sometimes they reduce first-time penalties, especially for small businesses.

Had a similar issue with my LLC last year! After stressing for weeks, I tried https://taxr.ai and it was incredibly helpful. You upload your documents and get a breakdown of what you actually need to file. In my case, I had also filed my personal return before my business return and was freaking out. The AI analyzed my situation and clearly explained that I needed to file my 1120S ASAP, then amend my personal return. It even highlighted that I could request penalty abatement since it was my first time making this mistake. Honestly saved me from a ton of confusion and probably money too!

•Does it actually work with business tax situations? Most of these tools seem to focus on basic W-2 stuff. Can it handle the specific S-Corp requirements like reasonable compensation testing and stuff?

•I'm skeptical about AI for something this important. How reliable is the advice? I've heard horror stories about tax software giving wrong advice and people ending up with huge penalties.

•Yes, it definitely handles business situations! That's actually where it shines compared to regular tax software. It analyzed my operating agreement, previous returns, and income statements to give specific S-Corp advice, including the reasonable compensation requirements you mentioned. It flagged that my salary was too low compared to distributions, which could have triggered an audit. For reliability, I was skeptical too, but everything is backed by specific tax code references and IRS guidelines. It's not just making stuff up - it's applying the actual rules to your specific situation. My accountant actually validated the recommendations when I brought them in. Much better than generic advice from forums.

I need to follow up on my skeptical comment. I actually tried https://taxr.ai after posting because I was in a similar situation with my S-Corp (but for a rental property business). I was really surprised by how thorough it was! It identified that I'd been incorrectly categorizing certain expenses between my Schedule E and my 1120S, and showed exactly which forms needed correction. The document analysis saved me hours of comparing my previous returns to figure out what was wrong. The penalty abatement letter template it provided worked too - I submitted it with my late 1120S filing and the IRS actually approved it! Definitely more useful than I expected for complex business tax situations.

If you're trying to contact the IRS about this situation, good luck getting through on their phone lines. I spent 4 hours on hold last month trying to sort out an S-Corp issue before giving up. I finally used https://claimyr.com and their service is pretty amazing. You can see how it works here: https://youtu.be/_kiP6q8DX5c - basically they hold your place in line and call you when an IRS agent is about to answer. I got through to an actual person who helped explain my filing requirements for my business. For your situation, I'd definitely recommend talking to the IRS directly to explain the mistake and ask about penalty relief options, especially since it's your first time filing these yourself. The agent I spoke with was surprisingly helpful with my S-Corp questions.

•Wait, how does this actually work? I've never heard of a service that can get you through to the IRS faster. Is this legit or some kind of scam?

•Yeah right. Nobody can get through the IRS phone system. I've tried for literal days and never reached a human. If this actually worked you'd be the first person in history to talk to a real IRS agent lol.

•It uses a combination of technology and human operators to continually call the IRS for you, navigating the phone tree and waiting on hold. When they're about to connect with an agent, you get a call and they transfer you in. So you don't have to waste hours listening to the hold music. I know it sounds too good to be true, but I was just as skeptical before trying it. It's basically like having someone else wait on hold for you. I've used it twice now - once for my business question and once about a missing refund. Both times I got through in less than an hour of my actual time (though they were working on it in the background longer).

Well I'm eating my words now. I was super skeptical about Claimyr but I was desperate to resolve my S-Corp filing issue before things got worse, so I tried it this morning. I was honestly shocked when my phone rang and it was actually connecting me to an IRS representative! Saved me from what would have been another day of frustration. The agent confirmed exactly what others here said - I needed to file the 1120S ASAP, then amend my personal return with the correct K-1 info. They also walked me through how to request first-time penalty abatement, which I might qualify for. Worth every penny not to spend another day listening to that horrible hold music!

For future reference, another option for S-Corp filing is to use Form 7004 to get an automatic 6-month extension for your 1120S. That would have pushed your deadline to September 15th instead of March 15th. A lot of S-Corp owners do this to give themselves more time to properly prepare their business returns, especially in the first few years when you're still figuring things out. Just remember you still need to pay any estimated taxes owed by the original deadline.

•That's really helpful to know for next year. Do you need to file anything special to request the extension or is it just a simple form? And does getting this extension for the business return also give you more time for your personal return?

•Filing for the extension is very straightforward - Form 7004 is a simple one-page form that you can e-file. You don't even need to provide a reason for needing the extension. The S-Corp extension does not automatically extend your personal return though. Those are separate filings with different deadlines. You'd need to file Form 4868 to extend your personal 1040 if needed. But having the business extension gives you more time to get the K-1 properly prepared, which makes your personal return more accurate when you do file it.

Friendly reminder that if you have an S-Corp LLC, you should be paying yourself a "reasonable salary" through payroll with appropriate withholdings. This is one of the most common mistakes new S-Corp owners make - taking distributions without paying yourself a proper salary first. The IRS looks closely at this.

•I learned this the hard way! My first year with an S-Corp I only took distributions because I thought that was the advantage. Got a nasty letter from the IRS later. Now I use Gusto for payroll and it makes the whole process super simple.
