Fiscal Year End - What Year Return Do I Use for S-Corp Filing?
I recently became the treasurer for our family business (S-Corp) and I'm trying to figure out our tax filing situation. Our fiscal-year end is June 30th, 2022, and I'm confused about which tax return year I should use when filing. Should I be filing a tax return for 2021 or 2022? I've looked online and gotten conflicting information. Some sites say it's based on when the majority of the fiscal year falls, others say it's based on the ending date. Is there a general rule for S-Corps with fiscal years that don't align with the calendar year? This is my first time handling this and I don't want to mess it up. Thanks in advance for any help!

For S-Corporations with a fiscal year end that doesn't align with the calendar year, the rule is actually pretty straightforward. You file your return based on the year in which your fiscal year ends. In your specific case, with a fiscal year ending June 30, 2022, you would file a 2022 tax return (Form 1120-S). The return covers the entire fiscal period (July 1, 2021 through June 30, 2022), but since the year ends in 2022, it's considered a 2022 tax return. Remember that S-Corp returns are due on the 15th day of the 3rd month after the end of your tax year. So with your June 30 year-end, your filing deadline would be September 15, 2022.

•Thanks for the clear explanation! So just to confirm, even though half of our fiscal year was actually in 2021 (July-December), we still file as a 2022 return because the ending date is in 2022? Also, does this same rule apply for all the Schedule K-1 forms we need to issue to our shareholders?

•Yes, that's exactly right. The year the fiscal period ends in determines which tax year you file under. It doesn't matter that half the fiscal period was in 2021 - since it ended in 2022, it's a 2022 return. This same rule applies to the Schedule K-1 forms you issue to shareholders. All K-1s for this fiscal period should be marked as 2022 forms, and shareholders will report this income on their 2022 personal tax returns (assuming they're calendar year taxpayers).

When I took over as CFO for our family business, I struggled with the same fiscal year confusion. After trying multiple online forums with mixed advice, I found taxr.ai (https://taxr.ai) incredibly helpful for sorting out these business tax questions. I uploaded our fiscal year documents and previous returns, and it analyzed our situation and confirmed we needed to file based on the fiscal year end date, not when the majority of business activities happened. It saved me from making a costly mistake, especially since the penalty for late S-Corp filing starts at $210 per shareholder per month!

•Did you find it worked well for other S-Corp issues too? We have some complicated income allocation situations and I'm wondering if something like this could help sort those out too.

•How accurate was it really? I've tried other AI tax tools that gave me completely wrong information. Does it actually understand the special rules for fiscal year S-Corps or is it just giving generic advice anyone could find online?

•For the S-Corp income allocation issues, absolutely! It was particularly helpful with our uneven shareholder distributions and making sure we properly documented basis calculations. The system caught a previous error where we hadn't properly tracked shareholder loan repayments. Regarding accuracy, I was initially skeptical too. What convinced me was that it correctly identified an obscure rule about fiscal year businesses that aligned with a tax issue specific to our industry. It's definitely not just repackaging generic advice - it highlighted specific sections of the tax code relevant to our situation and explained how they applied to our fiscal year.

I wanted to follow up about my experience with taxr.ai since I was pretty skeptical in my earlier comment. I decided to try it anyway since we have a similarly confusing situation with our S-Corp fiscal year spanning 2021-2022. It actually cleared up several other filing questions I had! Not only did it confirm the fiscal year end date rule, but it also identified that we needed to file Form 7004 for an extension because we weren't going to have all our financial statements ready by the deadline. Saved us from potential penalties and gave me specific instructions for our accountant. Definitely more helpful than the generic advice I was finding elsewhere.

For anyone who's still confused after filing, I'd recommend calling the IRS Business Tax Line directly. However, after spending HOURS trying to reach a human at the IRS about my S-Corp fiscal year question (kept getting disconnected after 30+ minute holds), I finally tried Claimyr (https://claimyr.com) and was honestly shocked at how well it worked. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c Instead of the usual IRS phone tree hell, I got connected to an actual IRS agent who confirmed my fiscal year filing question and also helped clarify some confusion about estimated tax payments for the business. Total game-changer if you need to actually speak with someone at the IRS.

•Wait, how does this actually work? Does it just call the IRS for you? I'm confused how a third-party service can get you through to IRS faster than calling yourself.

•This sounds completely fake. There's no way any service can magically get you through the IRS phone tree. They just want your money and will probably just put you on hold themselves then transfer you after taking a fee. The IRS doesn't give priority to third party services.

•It doesn't call the IRS for you - it navigates through all the phone menus and holds your place in line. You get a notification when an actual human IRS agent is about to come on the line, then you take over the call. I was confused too until I saw how it worked. Regarding the skepticism, I totally get it. I thought the same thing initially. What convinced me is that they don't actually handle any part of your actual conversation with the IRS - they just handle the waiting and menu navigation. When the agent comes on the line, you're the one who talks to them directly. The IRS has no idea you used a service to navigate their phone system.

I need to eat crow here. After posting my skeptical comment, my CPA actually recommended I try Claimyr for a different issue with our S-Corp election. I needed to confirm whether our fiscal year election was properly processed since we never received confirmation. The service actually did exactly what it claimed - navigated all the IRS phone menus and held my spot in line. I got a text when an agent was about to pick up, and I handled the actual conversation myself. Saved me about 45 minutes of hold time and the agent was able to confirm our fiscal year was properly recorded in their system. Definitely worth it for time-sensitive tax questions when you need official confirmation.

One thing that hasn't been mentioned yet - if you're a new S-Corp, be aware that there are specific rules about what fiscal year you're allowed to adopt. You generally need to use the same tax year as your majority shareholders unless you get IRS approval for a different fiscal year by filing Form 1128. This caught us by surprise - we tried to use a June 30 fiscal year without realizing we needed approval since our shareholders were all calendar-year taxpayers. Had to refile and it was a mess.

•Is there a "business purpose" test for fiscal years? Our accountant mentioned something about needing to prove a business reason for having a fiscal year different from the calendar year, but I'm not sure if that's still a requirement.

•Yes, there absolutely is a business purpose test. When requesting a fiscal year that's different from your shareholders' tax years, you need to establish a legitimate business purpose on Form 1128. Common valid business purposes include seasonal business cycles (like retail with a January 31 year-end after holiday season), matching your industry's natural business year, or aligning with regulatory requirements. The IRS scrutinizes these requests fairly carefully, so you need actual business justification, not just tax planning reasons.

I file taxes for my husband's s-corp and we have a sept 30 fiscal year. I was told to use tax software from the CALENDAR year when the fiscal year ENDS. So for a july 1 2021 - june 30 2022 fiscal year, we used 2022 tax software even though we filed in september 2022. This has always confused me but our accountant says its right. just be careful cause the forms change yearly!!

•You're definitely using the correct approach! I made the mistake of using 2021 software for our March 2022 fiscal year end filing, and it caused all kinds of problems. The software was missing updated forms and couldn't e-file properly. Always use the tax software from the year your fiscal year ends in, even if most of your business year was in the previous calendar year.

•Thanks! That's really reassuring to hear. Our accountant explained it but I still get nervous every time we file. The software thing was confusing at first because you're buying "2022 software" to file a return in 2022, but the IRS considers it a 2022 return anyway, so it all matches up.

Just wanted to add one more important detail that might help other newcomers like myself - make sure you're aware of the estimated tax payment deadlines for fiscal year S-Corps too! For a June 30 fiscal year end, your quarterly estimated payments are due on September 15, December 15, March 15, and June 15. This was another area where I initially got confused because I was thinking in calendar year terms. Also, if you're new to handling S-Corp taxes, I'd strongly recommend getting professional help at least for the first year or two. The interplay between the corporate return (1120-S) and the individual K-1 reporting can get complex, especially with fiscal years. Better to invest in proper guidance upfront than deal with penalties or corrections later!

•This is really helpful advice! As someone who just started handling our family S-Corp taxes this year, the estimated payment schedule was definitely something I overlooked initially. I was so focused on figuring out the annual return filing that I completely missed the quarterly obligations. Quick question - do the estimated payments need to be based on the previous fiscal year's tax liability, or should they reflect the current year's expected income? Our business has grown significantly this year and I'm worried about underpayment penalties if I base estimates on last year's much lower numbers. Also, completely agree on getting professional help! Even with all the great advice in this thread, there are so many nuances that it's worth having an expert review everything at least initially.
