A tax extension gives you additional time to file your tax return, extending the deadline to:

  • September 15 – for Partnerships and multi-member LLCs (originally March 15)
  • October 15 – for Individuals, Sole Proprietors and Single Member LLCs (originally April 15)

However, an extension does not allow you to delay payment of any taxes owed. Any unpaid taxes after the original filing deadline will incur penalties and interest. To avoid these charges, you must pay your estimated taxes by the original due date, even if you request an extension to file.
