Updated for tax year 2024.
Do you need more time to file your business return this year? No sweat — that’s what tax extensions are for. Read on to learn more about filing for a business tax return extension this tax season.
What is a business tax extension?
Sole proprietorships, partnerships, LLCs, and corporations can file a six-month business tax extension request with the IRS to receive extra time to complete their income tax return without penalty. Which request form you need to file depends on your business structure:
• Sole proprietorships and single-member LLCs use IRS Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return.
• Partnerships, multi-member LLCs, and corporations use Form 7004, Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns.
Generally, the extension period is automatic if you file your request by the due date. To submit your form, you can request an extension online (TaxAct® can help you do this when you e-file with us using our tax preparation software) or submit an extension request by mail.
What is the filing deadline to request a business tax extension?
The deadline for filing a business income tax extension request using the above tax extension forms depends on what type of business entity you have:
Sole proprietorships, single-member LLCs, and C corporation returns:
• Deadline to request extension (tax year 2024): April 15, 2025
• New tax filing deadline with extension: Oct. 15, 2025
Partnerships, S corporations, and multi-member LLCs:
• Deadline to request extension (tax year 2024): March 17, 2025
• New tax filing deadline with extension: Sept. 15, 2025
Be sure to request an extension before the original due date in March or April to avoid late filing penalties!
Does a business extension give me more time to pay my small business taxes?
No, filing an extension only gives you more time to complete your business tax return. You still need to pay any outstanding tax due by the April 15 deadline (March 15 for partnerships and S corporations). If the 15th falls on a weekend or holiday, the due date becomes the next business day. Failing to pay all or some of your tax liability can result in late payment penalties and interest charges.
How do I calculate the estimated tax I need to pay?
• If your tax situation hasn’t changed much, one solution is to approximate your numbers from a previous year’s return.
• For assistance, check out Calculating and Paying Quarterly Estimated Taxes, which provides instructions on how to calculate estimated taxes for next year using TaxAct.
• The IRS also provides helpful calculation worksheets covering many different taxpayer scenarios.
When in doubt, it is in your best interest to overpay rather than underpay to avoid being charged any interest and penalties for any unpaid tax debt. If you pay more tax than you owe, you will be able to reclaim it as a tax refund.
Are there any benefits to filing a business tax extension?
Yes, sometimes! Small business owners or self-employed individuals with SEP IRAs may find it beneficial to file a business tax extension because it extends the time you have to contribute to your plan. If you’re unfamiliar, a SEP-IRA is a variation of an IRA built for sole proprietors, freelancers, or any other small business owners. If you are self-employed and have one of these funds, make any additional deposits before the Oct. 15 extended due date. And don’t forget to update your federal tax return based on your contributions. Remember — you’re funding your account for the previous tax year, not this year.
When should I file a tax extension?
If you need more time to file for any reason — whether you are still waiting on certain tax documents, had a family emergency come up, or simply procrastinated too long — don’t hesitate to file an extension. You don’t have to convince the IRS of anything, and the tax filing extension is automatic. So, if you need more time, just ask for it!
When shouldn’t I file a business tax extension?
If you need more time to pay your taxes owed, the extended deadline will only give you more time to file, not more time to pay.
Instead, the IRS has debt relief options available for any taxpayers struggling to make tax payments. Read our article on how to set up an IRS payment installment agreement that can split up your bill into more manageable monthly payments.
In certain situations, you’ll automatically qualify for an extra six months to file and do not need to request an extension. These exceptions are:
• You (or your spouse) are working in a combat zone for the U.S. Armed Forces
• You are a member of the military serving abroad
• You are a U.S. citizen living and working outside the country
• You are a U.S. citizen residing in a part of the country affected by a severe natural disaster
What information will I need to file my business extension request?
Form 7004 has been simplified and now consists of two parts:
• Part I lists all the tax forms you could be requesting an extension for, along with a different code for each return. If you need to request an extension for more than one type of return, you’ll need to submit separate 7004 forms.
• Part II asks for basic information about your business, such as your business structure, location, and the dates of your calendar year and tax years. You’re also asked to estimate your tentative total tax and include your total payments and tax credits.
How do I file a tax extension for my business?

What should I do after filing my business tax extension?
Though you now have an extra six months to file your return, please don’t put it off until the last minute! Even with the new extension deadline, try to complete your return as soon as possible while the last tax year is still fresh in your mind. Don’t forget to make any necessary retirement plan contributions for the previous tax year as well.
Do I need to file a business extension for my state tax return?
Certain states will allow an accepted federal Form 7004 or 4868 as an extension of time to file your state return, while other states require a separate extension request. TaxAct will provide information about state filing requirements during the extension interview portion of the e-filing process.
Can I also get an extension for my personal tax return?
