How long of an automatic extension can a calendar year C corporation receive to file its return?

For a calendar year C corporation, the automatic extension to file its tax return is indeed six months. The original deadline for filing the return is the 15th day of the fourth month following the end of the tax year, which for calendar year corporations would be April 15. With an automatic extension, the new due date would be October 15.

This six-month extension allows corporations additional time to prepare their returns without incurring penalties for missing the original deadline. The extension does not apply to the payment of any taxes owed; corporations are still required to estimate and pay their taxes by the original filing deadline to avoid interest and penalties.

Other options, such as nine months, seven months, or three months, do not align with the standard provisions established for C corporations seeking an extension. Therefore, understanding the six-month extension is crucial for compliance and strategic tax planning for corporations.
