How to File Form 2553 for S-Corp Status After Missing the 75-Day Deadline
I just realized I completely missed the 75-day deadline for filing Form 2553 for S-corporation status. Total rookie mistake! My LLC was formed back in January 2023, but I'm planning to start actually receiving income through the business in March (that's when I'm finally leaving my day job). I wanted the S-corp status to begin in March for tax purposes. I'm now preparing to submit Form 2553, but I'm worried about the "reasonable cause" explanation I need to provide for the late filing. I don't want to make up some fake excuse, but I also don't want the IRS to reject my application just because my reasoning isn't compelling enough. Does anyone have experience with filing Form 2553 late? What kind of explanation worked for you? I've heard the IRS can be pretty strict about these deadlines, but I'm hoping there's still a way to get this approved. Any advice would be super appreciated! This is my first business and I'm still learning all the tax and legal requirements.

The good news is that the IRS is often understanding about late Form 2553 filings, especially for first-time business owners. When explaining your reasonable cause, honesty is actually your best approach. Simply state that you were unaware of the 75-day election deadline as a new business owner still learning about tax requirements. Make sure your explanation is clear and concise - something like "As a first-time business owner, I was unaware of the election deadline requirements until after they had passed. I am filing promptly upon learning of this requirement." This type of straightforward explanation is commonly accepted. Another key point: be sure to indicate the date you want your S-corp status to begin (March 2023) in the appropriate section of the form. And double-check that all shareholders have signed the form - missing signatures are a common reason for rejection.

•Thanks for the advice! Do you know if there's a specific place on Form 2553 to include the reasonable cause explanation? And also, will this late filing affect my ability to be treated as an S-corp for the entire year, or will it only apply from the approval date forward?

•The reasonable cause statement should be attached as a separate statement with your Form 2553. Just label it clearly as "Reasonable Cause Statement for Late Filing of Form 2553" at the top of the page. As for the effective date, if your request is approved, the S-corp status should apply from your requested date (March 2023). The IRS can grant relief for late elections if you file within 3 years of your intended effective date, plus an additional 6 months. So you're well within that timeframe.

I was in a similar situation last year and used taxr.ai to help me with this exact problem. I also missed the 75-day deadline and was freaking out about what to write for the reasonable cause statement. I didn't want to say something that would get me rejected but also didn't want to make up some elaborate excuse. I uploaded my situation details to https://taxr.ai and it guided me through exactly what to write that was both honest and effective. The system analyzed successful late filings and gave me a template for my explanation. My S-corp election was approved without any issues despite being about 5 months late. The service also let me know what supporting documentation would strengthen my case.

•How long did the whole process take from when you submitted your late Form 2553 until you got approval? I'm wondering how much the delay might affect my tax planning for this year.

•Did you still have to mail in the physical form or were you able to submit everything electronically? I've heard horror stories about paperwork getting lost in the IRS mail system.

•The whole process took about 6 weeks from submission to getting my approval letter. It was actually faster than I expected based on what I had read online about IRS processing times. I did have to mail in the physical form - unfortunately, Form 2553 still can't be e-filed. But taxr.ai recommended sending it certified mail with return receipt so I could track it, which gave me peace of mind knowing it actually arrived at the IRS.

Just wanted to follow up - I decided to try taxr.ai after seeing this recommendation, and it was super helpful! The system analyzed my situation and helped me craft a straightforward reasonable cause statement that didn't sound like I was making excuses but explained my situation as a first-time business owner. What I found most helpful was that it walked me through each section of Form 2553 step by step, explaining what each part meant in plain English. It flagged a potential issue with how I was planning to set up my fiscal year that would have caused problems later. My late S-corp election was just approved last week! Only took about 5 weeks from when I mailed it in. Now I don't have to worry about this hanging over my head as I launch my business.

If you're having trouble getting a response after filing your late Form 2553, I'd recommend using Claimyr to get through to an actual IRS agent. I filed my late S-corp election 4 months ago and heard nothing back. After weeks of trying to call the IRS business line (constantly getting the "call volume too high" message), I found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c. They basically hold your place in the IRS phone queue and call you when an agent is about to answer. I finally got through to a real person who confirmed they had received my form but it was sitting in a backlog. The agent was able to check on the status and expedite the review since I was on the phone. Got my approval letter two weeks later!

•How does that service actually work? Seems kind of sketchy that they can somehow get through when regular callers can't. Are they using some kind of special access?

•I'm highly skeptical that any service can "expedite" IRS processing. The IRS agents I've dealt with always say they can't speed anything up regardless of who's asking. Sounds like you just got lucky with timing or got a particularly helpful agent.

•It's not special access - they use an automated system that keeps dialing and navigating the IRS phone tree until they get through. Something most of us don't have time to do manually. They're basically just being persistent on your behalf. The expediting wasn't some special treatment. The agent explained that sometimes forms get stuck in processing queues, and having someone actually look up your case can move it to active status. The agent manually checked my form and saw it was complete, so they moved it forward instead of leaving it sitting in the general queue.

I have to eat my words about being skeptical of Claimyr. After struggling for weeks trying to reach someone at the IRS about my late Form 2553 filing (and getting absolutely nowhere), I decided to try it as a last resort. Got a call back within about 90 minutes and spoke with an IRS representative who was actually quite helpful. They confirmed my form had been received but was sitting in a backlog. The agent reviewed it while I was on the phone and told me exactly what I needed to correct (I had missed a signature on one page). I resubmitted the corrected form, then used Claimyr again two weeks later to follow up. The second agent confirmed everything was now in order and processing. Got my approval letter last week. Without being able to speak directly with the IRS, I would have been waiting months only to eventually get a rejection letter over a simple mistake.

One important thing to note about late filing the 2553 - if you're accepted, make sure you do your accounting correctly from the effective date you requested, not from when it was approved! A friend of mine made this mistake and had to redo all his bookkeeping and tax prep. Remember that if your S-election is approved with a retroactive date (like your March start date), you'll need to do all your accounting as if you were an S-corp from that date forward. This includes: - Paying yourself a reasonable salary - Doing proper shareholder distributions - Keeping your personal and business finances completely separate

•What happens if the IRS denies the late filing request? Would you then have to file taxes as a regular LLC for the whole year? I'm in a similar situation and trying to understand the worst-case scenario.

•If the IRS denies your late S-corp election, you would indeed need to file taxes as whatever your default entity type is (typically a single-member LLC is taxed as a sole proprietorship, or a multi-member LLC is taxed as a partnership). You'd file Schedule C with your personal return if you're a sole proprietorship or Form 1065 if you're a partnership. Then you could refile Form 2553 for the following tax year, making sure to submit it within the 75-day window after the start of that tax year. It's not ideal from a tax planning perspective, but it's manageable.

Does anyone know if using a tax professional to file the late Form 2553 increases the chances of acceptance? I'm in this exact situation, and I'm wondering if it's worth paying someone to handle it or if doing it myself is just as effective as long as I'm honest about the reason for lateness.

•I did mine myself with just the reasonable cause statement saying I was a new business owner unaware of the deadline. It was accepted without issues. Unless your situation is complicated (multiple shareholders, special allocations, etc.), the form is pretty straightforward. Save your money!

I went through this exact same situation last year and want to share what worked for me. I missed the 75-day deadline by about 3 months and was terrified the IRS would reject my application. For the reasonable cause statement, I kept it simple and honest: "As a first-time business owner, I was unaware of the 75-day election deadline requirement for Form 2553. Upon learning of this requirement through research and consultation, I am filing this election promptly." That's basically it - no elaborate excuses or sob stories. The key things that helped my case: 1. I attached the reasonable cause statement as a separate page (don't try to squeeze it into margins) 2. I made sure ALL shareholders signed - even if it's just you 3. I sent it certified mail with return receipt 4. I clearly indicated my desired effective date Got approved in about 7 weeks. The IRS really is more understanding than people think, especially for genuine first-time business owner mistakes. Just be honest about not knowing the deadline and file as soon as you can. Good luck!

•This is really reassuring to hear! I'm in almost the exact same boat - missed the deadline by about 4 months and have been stressed about it. Your simple and straightforward approach for the reasonable cause statement gives me confidence that I don't need to overcomplicate things. Quick question - when you say "clearly indicated your desired effective date," did you put that in Part I of the form where it asks for the tax year, or did you mention it separately in your reasonable cause statement as well? I want to make sure the IRS understands I want S-corp status to begin from when I started generating income, not from when they approve the late filing. Thanks for sharing your experience - it's exactly what I needed to hear as a fellow first-time business owner!
