If your business is taxed as an S-Corporation, your federal tax return (Form 1120-S) is due on March 15, 2026. Not April 15. March 15.
Miss this deadline without filing an extension, and the IRS imposes a penalty of $250 per shareholder, per month — for up to 12 months. For a single-shareholder S-Corp that files just 3 months late, that’s $750 in completely avoidable penalties.
Here’s the good news: filing an extension (Form 7004) gives you until September 15 to submit your complete return — penalty-free. But the extension itself must be filed before the March 15 deadline.
Don’t scramble to file a rushed return. Don’t risk errors that trigger IRS notices. A properly filed extension gives you the breathing room to finalize your books, confirm your officer compensation, and ensure every deduction is accounted for.
You still have time — but not much.
When you hire Simplify My Numbers to handle your extension, you’re not just avoiding penalties — you’re getting a head start on saving money.
Here’s what’s included:
Why do we include the strategy session? Because every time we review an S-Corp’s filing data, we find optimization opportunities — adjusting reasonable compensation, maximizing distributions, planning for estimated taxes, and evaluating retirement plan contributions. We’d rather show you what’s possible than let those savings slip through the cracks.
