Requesting a Second Tax Extension For a Business

(This article was last updated on September 17, 2026.)

For most taxpayers, there is no second federal tax extension. If you request an extension by the original filing deadline, you generally receive an automatic six-month extension to file. For calendar-year individual taxpayers, that typically moves the filing deadline from April 15 to October 15.

(This wasn’t always the case. Before the current system was introduced, individual taxpayers generally received an initial four-month extension and could request an additional two months if they needed more time. The IRS replaced that two-step process with a single automatic six-month extension beginning with 2005 tax returns.)

Keep in mind that an extension gives you more time to file, not more time to pay. If you expect to owe taxes, you should estimate and pay as much as possible by the original tax deadline. Otherwise, interest and potentially late-payment penalties may continue to accrue.

There are only a few specific exceptions to the October 15 deadline

Certain taxpayers may qualify for additional time under special IRS rules. For example, U.S. citizens and resident aliens living and working outside the United States may receive additional time to file, and qualifying taxpayers who are outside the country may be able to request additional time beyond October 15.

Special rules also apply to members of the Armed Forces and others serving in designated combat zones or contingency operations. These rules can postpone both filing and payment deadlines and are different from a standard tax filing extension.

Taxpayers affected by certain federally declared disasters may also receive additional time to file and pay when the IRS announces tax relief for their area.
