S-Corporation Election for LLC Late in Year - Do I Need Separate Tax Return or Extension Form 7004?

Yes, you absolutely need to file a separate tax return (Form 1120-S) for your S-Corporation even though you elected this status in October. The IRS considers your business an S-Corp from the election date through the end of the year, so you'll need to file for that partial period. Since today is March 15th (the deadline for S-Corp returns), you should immediately file Form 7004 to request an automatic 6-month extension. This buys you time to properly prepare your S-Corp return. You'll need to file two different business tax documents for 2023: 1. Schedule C (with your personal return) for the LLC portion from January 1 to October 10 2. Form 1120-S for the S-Corp portion from October 11 to December 31

I went through this exact situation last year and found an amazing tool that saved me tons of time and stress. I used https://taxr.ai to help separate my business finances into the pre-S-corp and post-S-corp periods. I uploaded my bank statements and QuickBooks reports, and it automatically sorted transactions and generated separate financial statements for both tax periods. What would have taken me days of manually splitting records took just minutes. The tool also flagged potential audit triggers specific to mid-year S-corp elections.

I wanted to follow up and say I tried https://taxr.ai after seeing this thread and it was incredibly helpful! I was seriously struggling with how to handle my receivables situation where clients paid me in December for work completed before my S-corp election. The tool correctly identified that for cash-basis taxpayers, the income belongs to the period when payment was received (S-corp) rather than when the work was performed (LLC). It also helped me understand that for accrual-basis, it would be the opposite. This alone saved me from a potentially serious reporting error. The financial statements it generated for both periods were perfectly formatted for giving to my accountant. Definitely worth checking out if you're in this mid-year election situation!

If you're still struggling to reach the IRS for clarification on your S-Corp election timing, I highly recommend using https://claimyr.com to get through to an actual IRS agent. I was facing a similar situation with my LLC/S-Corp election last year and couldn't get clear answers online. I tried calling the IRS business line directly for weeks but kept getting disconnected or faced hours-long hold times. Then I found Claimyr, which literally had me talking to an IRS representative in under 30 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with confirmed exactly how to handle the mid-year election and gave me specific guidance on completing Form 7004 correctly. Saved me a ton of stress and potential penalties.

I need to eat my words. After posting my skeptical comment, I was desperate enough to try Claimyr since my CPA wasn't sure about how to handle my mid-year S-corp election. I figured I had nothing to lose. I was honestly shocked when I got a call back in about 20 minutes connecting me to an actual IRS business tax specialist. The agent walked me through exactly how to complete Form 7004 for my situation and confirmed I needed two separate filings for the year (Schedule C and 1120-S). The agent even explained that I should check box "d" on Form 7004 (for Form 1120-S) and noted that the return would be for a "short tax year" due to the mid-year election. This was specific information my CPA wasn't completely sure about. Definitely worth it for time-sensitive tax questions like this!

Worth mentioning that you also need to pay yourself a reasonable salary as an S-Corp owner! Since you elected S-Corp status in October, you should have set up payroll and paid yourself at least one quarter of a "reasonable salary" for your industry and area. The IRS watches this closely. If you didn't run any payroll in Q4 2023, you might want to consult with a tax pro ASAP about your options. Sometimes they can help you retroactively set up and run payroll to avoid raising red flags.

Don't forget about your state filings too! Depending on your state, you may need to file separate state tax returns for the S-Corp period as well. Some states automatically recognize the federal S-Corp election, while others require a separate state election.

Just went through this exact scenario last year! A few additional things to keep in mind that saved me from headaches: 1. **Estimated tax payments**: If you made estimated tax payments as an LLC during 2023, you'll need to figure out how to allocate those between your Schedule C and S-Corp portions. The IRS considers them made ratably throughout the year unless you can prove otherwise. 2. **Asset basis transfer**: When you elected S-Corp status, any business assets (equipment, inventory, etc.) transferred from the LLC to the S-Corp at their adjusted basis. Make sure you're tracking this correctly for depreciation purposes on both returns. 3. **Health insurance deduction**: If you were deducting health insurance premiums as self-employed health insurance on Schedule C, you can continue doing this on your personal return for the S-Corp period (since you'll be a >2% shareholder). But the mechanics change slightly. Definitely get that Form 7004 filed today if you haven't already! The automatic extension is your friend here and gives you time to sort through all these details properly.
