Final answer:
A tax return extension for a corporation with a calendar year-end will extend the due date by 6 months, from April 15 to October 15. This extension is for filing the return, not for the payment of any owed taxes.
Step-by-step explanation:
If a corporation has a calendar year-end, a tax return extension will extend the due date for 6 months. This means that if the original tax filing deadline was April 15, the new extended deadline will typically be October 15. It is essential to note that this extension applies to the filing of the return, not the payment of any taxes owed. If taxes are owed, they are still due by the original filing deadline to avoid potential penalties and interest.
If a corporation has a calendar year-end, a tax return extension will extend the due date for 6 months.
