Extended Tax Deadlines for 2025: Do You Qualify?

The Internal Revenue Service (IRS) offers extended tax deadlines to qualifying individuals and businesses.

You may be wondering if you qualify for a 2025 tax extension or how to go about it for one of the following dates: 

• May 1 extension for Hurricane Helene 

• June 16 or September 16 quarterly estimated taxes 

• October 15 extension for the Los Angeles County wildfires 

• November 3 extension for Kentucky storms and flooding

Extensions are typically created due to federal declarations, various natural disasters, and IRS system issues and delays. Common scenarios that might trigger an extended tax deadline include: 

• Taxpayers in disaster-declared areas

• Businesses filing quarterly estimated taxes

• Taxpayers who filed IRS Form 4868 for personal tax extensions

Use this blog to understand if you or your business qualifies for an extension, what you should know if you do, and other considerations, such as the consequences of missing a tax deadline extension. 

Key Extended Tax Deadlines for 2025

Federal Income Tax Extensions

Individuals and businesses can file federal income tax extensions, typically giving them six additional months to file. However, this usually doesn't afford them extra time to pay. Payments must be submitted to the IRS or other tax authorities by the original deadline to avoid penalties. 

Individual Taxpayers

Individual taxpayers, including W-2 employees and pass-through business owners, will typically submit their completed return and any payments by the April 15 filing deadline. However, sometimes people need extra time to prepare and file their tax return accurately, which is why the IRS offers an automatic six-month extension.

Individual taxpayers should complete and submit IRS Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, before the April 15 deadline to request additional time.

Because the extension is granted automatically, taxpayers usually won't receive confirmation, but they are free to contact the IRS to confirm as an additional safety measure. 

Businesses and Corporations   

Like individual taxpayers, businesses and corporations, including S corporations, C corporations, and partnerships, can also file for an extension. While the base process is essentially the same, businesses and corporations use different forms and may have different extension dates. 

C corporations must file a return by April 15, while S corporations and partnerships must file by March 15. Because the filing date fell on a weekend in 2025, the filing deadline for S corporations and partnerships was moved to the next business day, March 17. 

S corporation, C corporation, and partnership owners can file for an automatic six-month filing extension using IRS Form 7004, Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns. 

Like IRS Form 4868, businesses will not receive a confirmation from the IRS regarding this extension. 

Quarterly Estimated Payments

Businesses in states and areas impacted by disaster declarations typically receive an extension to file quarterly estimated taxes. Unlike the extensions detailed above, businesses don't normally file for this type of extension.

The extension dates aren't uniform from state to state, so impacted businesses should check with the IRS or other authorities to confirm their new quarterly estimated tax deadlines. 

IRS Disaster Relief Extensions

Unfortunately, several events and disasters have caused the need for the IRS to extend filing dates for individuals and businesses impacted. Browse the IRS's Tax relief in disaster situations page for more information, including state-level details and tax relief by date.

The IRS also provides helpful FAQs for disaster victims on tax returns, payments, and the definition of an impacted taxpayer.

According to the IRS, an affected taxpayer includes an individual, any business entity or sole proprietor, and any shareholder in an S corporation. Taxpayers do not have to be located in a federally declared disaster area to be an “affected taxpayer”. They are considered “affected” if records necessary to meet a filing or payment deadline are postponed during the relief period in a covered disaster area.

What Happens If You Miss the Extended Deadline?

Taxpayers and businesses who miss the extended tax deadline may receive penalties from the IRS. If you need more time beyond the applicable deadline, you may be able to file an extension, which will provide more time to file but not to pay.

If you miss the extended deadline, submitting your tax return as soon as possible is in your best interest. IRS penalties accrue, so the sooner you file, even if it's late, the better.

If you can't pay your tax bill immediately, consider applying for an IRS payment plan to ensure you pay your balance over time. You may apply as an individual, an authorized representative of someone else, or a business. Apply online with the IRS for immediate approval notification and eligibility requirements.
