Final Day to File Business Tax Return: TaxZerone Urges Businesses to File Their Return Today or Request an Extension

TaxZerone helps businesses e-file Form 1120-S or 1065 today or request a 6-month IRS extension (Form 7004), giving them extra time to file before the deadline.

SAN JOSE, CA, UNITED STATES, March 16, 2026 /EINPresswire.com/ -- FINAL DAY ALERT: U.S. businesses have just hours left to e-file IRS Form 7004 and secure an automatic extension on their federal business tax returns. TaxZerone, a leading IRS-authorized e-file provider, is urging S-corporations and partnerships to act immediately before the deadline expires at midnight.

Because March 15 falls on a Sunday in 2026, the deadline for filing Form 7004 is the next business day, Monday, March 16, giving businesses one final day to submit their extension request and avoid late filing penalties.

What is Form 7004?
Form 7004, the IRS Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns, provides eligible businesses up to a 6-month extension, allowing extra time to organize records, reconcile accounts, and file accurate returns without rushing.

“Today is the last opportunity for S-corporations and partnerships to avoid penalties and interest,” said a TaxZerone spokesperson. “Filing Form 7004 now ensures compliance and peace of mind, and our platform makes it fast, secure, and simple — even on the busiest filing day of the year.”

Why the March 16 Deadline Matters
March 16, 2026, is the filing deadline for calendar-year S corporations (Form 1120-S) and partnerships (Form 1065) for the 2025 tax year. Businesses that are not ready to submit their complete tax return must file Form 7004 by this date to request an automatic extension of time to file.

Important: Form 7004 extends the time to file the return, but not the time to pay taxes owed. Businesses should estimate and pay any expected tax liability by the original deadline to avoid additional charges.

If you’re ready to file your business tax return (Form 1120-S or 1065), e-file today with TaxZerone. Our secure, IRS-authorized platform ensures accurate filing, generates Schedule K-1s, and lets you share them safely via secure portal (ZeroneVault) or encrypted email.

IRS Penalties for Late Filing or Payment
Businesses that miss the filing deadline without submitting Form 7004 may face IRS penalties.
✔️ Failure-to-File Penalty: Generally, 5% of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25% of the unpaid tax.
✔️ Late Payment Penalty: If taxes remain unpaid after the deadline, the IRS may charge 0.5% of the unpaid tax per month, up to a maximum of 25% of the unpaid amount.
✔️ Interest Charges: Interest may also apply to any unpaid balance until the tax is fully paid.

Filing Form 7004 on time helps businesses avoid the failure-to-file penalty and provides additional time to complete their tax return accurately.
