Who Must Meet This Important Deadline?

For individuals or businesses that fall under certain federal tax classifications, today is the final day to file their income tax returns with the IRS. 

• Individuals: 1040, 1040-NR, and other 1040 series
• C-Corporations: Form 1120

Need More Time to File? File an Extension

It’s the final day to file your taxes—and if you’re feeling the pressure to get everything done perfectly, you’re not alone. The good news? You don’t have to rush through it. Filing a tax extension is a smart way to stay compliant while giving yourself the time you need to file confidently.

The extension form you need to file depends on your federal tax classification. For example,

• If you’re a sole proprietor and need more time to file your Form 1040, you can request additional time by filing Form 4868.
• If you’re a C-Corp and need more time to file your Form 1120, you can file Form 7004 to extend the filing deadline.

No explanations required—just submit the correct extension form, and you’ll receive an automatic 6-month extension from the IRS.

Things to Remember When Filing an Extension

Before you begin the extension filing process, keep these key points in mind to avoid common errors and ensure your request is processed smoothly:

• Verify Your Information
  Double-check that your name (or business name), EIN, and other identifying details match IRS records exactly. Even small mismatches can delay or reject your extension request.
• Choose the Correct Extension Form
  Selecting the right extension form is crucial. Filing Form 4868 for individual returns or Form 7004 for business returns? Make sure the form aligns with the type of return you’re extending. Submitting the wrong form can lead to rejection.
• Enter the Correct Form Code
  Each return type has a designated form code that must be included when filing Form 7004. Using the correct code ensures your extension is applied to the right return and helps prevent delays.

What Happens If You Miss the Deadline?

Failing to file your return—or your extension—on time can result in IRS penalties. These vary based on whether you missed the filing deadline, the payment deadline, or both.

• Late Filing Penalties: If you don’t file your return (even with an extension), the IRS may impose a 5% penalty per month, up to 25% of the unpaid tax.

• Late Payment Penalties: Even with an approved extension, any unpaid taxes are still due by the original deadline. If you don’t pay on time, the IRS charges interest and a 0.5% penalty per month on the balance due.

To avoid these penalties, file your extension on time and pay any balance you owe before the deadline.
