What to know about filing a business tax extension this year

Filing a business tax extension – Key takeaways

• Filing a business tax extension only gives business owners more time to submit their tax return – it does not extend the deadline to pay any taxes owed.
• Entrepreneurs can request a business tax extension by submitting IRS Form 4868 for personal returns or IRS Form 7004 for business entities, typically by the original tax deadline.
• An extension typically gives you six extra months to file your business taxes, but the tax extension deadline date depends on your original filing deadline.

Long story short, if you chose to file a tax extension for 2024 taxes (taxes filed in 2025), you’ve likely secured some extra wiggle room to sort everything out. Keep reading to learn when business extensions are due and how they can help you avoid certain penalties.

Steps for filing business tax extensions

If you’re looking to wrap up your business tax extension filing for the 2024 tax year as soon as possible, the first step is to gather your tax and financial documents, like your profit and loss statement or income statement.

It’s a good practice to file your business tax return as early as possible – that goes with business extension filing too. If you’re coming across this article in the spring, you may still need to request your business tax extension. It’s completely normal to feel overwhelmed during tax season and even extension tax season, especially if you are a new business owner. If the whole business tax extension process is making you anxious, don’t worry – Block Advisors tax pros are here to help you through every step.

To file a business tax extension, you or your tax professional should complete and submit IRS Form 4868 or IRS Form 7004, depending on the type of business entity you own. However, there are specific deadlines for business tax extension requests!

Business tax extension deadline 2025

Tax form 4868 or Form 7004 must be filed by the due date of the business return. Note that even if you file an extension for your business tax return, you still need to figure your estimated tax (if you owe) and make your estimated tax payment by the original due date of the return.

So, what are the due dates for filing an extension form? If your business is an S Corporation or Partnership, you must submit your business tax return or file for a tax extension by the 15th day of the 3rd month after your tax year ends (March 15 for a calendar year business). If your business is a C Corporation, you must submit your business tax return or file for a tax extension by the 15th day of the 4th month after the end of your tax year (April 15 for a calendar year business).

Which business tax extension form should you file?

The following pass-through business structures should file Form 4868:

• Sole proprietorships
• Single-member LLCs filing as a sole proprietorship

The following business structures should file Form 7004 (Note that you can e-file the 7004 form):

• Corporations
• Multiple-member LLCs filing as partnerships or S corporations
• Partnerships
• S corporations

By filing Form 4868 or Form 7004, the Internal Revenue Service will give you another six months from the original due date of the return to complete your return. For example, if your return is originally due April 15 and you file as a sole proprietorship, after you file for a 2025 tax deadline extension, you have six months (until October 15) to turn in your business taxes. Other entities might have different due dates for their business returns, like March 15; in that case, an extension would give them until September 15 to file their business taxes for 2025.

We know small business owners wear a lot of different hats. Sometimes you just need a little more time — or a lot. No matter your situation, Block Advisors is here to help make the process as easy as possible.

Guidance on how to file an extension

As you’re reading through how to file a tax extension for your 2025 taxes, there are a few rules you need to be mindful of as a business owner.

1. Your extension of time to file is not an extension of time to pay your taxes. Generally, you must pay at least 90% of your tax liability to avoid the failure-to-pay penalty. Thus, it’s important to take the time to figure out your total taxable earnings for the year. This may require additional completion of small business tax forms.
2. States have different rules on filing extensions. Many states require you to file a state extension in addition to a federal extension. You can look up your state to determine the rules.

Why filing a business tax extension is important

Why should you care about learning how to file an extension for your business’s taxes? If you don’t take action on your tax return on or before Tax Day, you could be subject to penalties. If you file your federal tax return late and owe tax with the return, two penalties may apply.

1. A failure-to-file penalty for late filing.
2. A failure-to-pay penalty for paying late.

The failure-to-file penalty is normally 5% of the unpaid taxes for each month or part of a month that a tax return is late. The failure-to-pay penalty is 0.5% per month or part of a month. When the two penalties are combined, the late filing penalty drops to 4.5%, so the total penalty is 5% for each month or part of a month the return was late.

The late filing penalty maxes out at 25% of the unpaid taxes (about 5 1⁄2 months); the late payment penalty continues to run until it, too, reaches 25% of the unpaid tax.

If you’re holding off on filing because you can’t pay your business taxes right now, don’t let that keep you from filing.
