How to apply for a tax extension

If it seems like you won’t be ready to file your taxes on time, you should file for an extension as soon as possible.

Why? Because, if you file late, you’ll pay a penalty. The IRS charges you 5% of your outstanding income tax balance, plus an additional 1% for every month you fail to file, up to a maximum of 12 months. So, if you file your taxes 12 months late, you’ll pay an extra 17% on your taxes.

How to file for a partnership, S corporation, or C corporation extension online

If your business is a partnership, S corporation, or C corporation—or an LLC filing as one—you’re slightly more limited in how you can file for an extension.

You’ll need to file IRS Form 7004 through the IRS’ e-file service. If you’re filing multiple returns this year, you must file a different Form 7004 for each.

After specifying which return you’re filing an extension for, you’ll use Form 7004 to let the IRS know: 

  • If your organization is a foreign corporation without an office or place of business in the U.S.

  • If your organization is a corporation and the common parent of a group that will be filing a consolidated return.

  • If the organization is a corporation or partnership that qualifies under Regulations section 1.6081-5.

  • The dates of your calendar and tax years.

  • Whether you’re filing a short tax year, and if so, why.

You’ll also need to provide an estimated total for the taxes you have due, and information on any payments you’ve already made or credits you qualify for.

The deadline to file for a tax extension is the same as your tax filing deadline.
