Filing an extension

Need more time to file your taxes? You can request an extension up until the day your taxes are due. An easy and fast way to request an extension is through an authorized e-file provider.1 If the IRS approves your request, you can file later without paying any penalties. But remember, the extension granted is for filing and does not affect your payment responsibilities. You will typically have to pay any taxes you owe by the original deadline.

To file an extension, sole proprietors and owners of single-member LLCs taxed as a disregarded entity should use Form 4868. Corporations, LLCs and partnerships should use Form 7004.

If you do request an extension, your new deadline will be:

  • Partnerships and S-corporations: Sept. 15, 2020
  • Sole proprietorships, C-corporations, and LLCs taxed as a disregarded entity: Oct. 15, 2020
