An extension filed using Form 7004 typically grants an additional six months to file certain tax returns. For example:
- For calendar year corporations (those with a tax year ending on December 31st), filing Form 7004 extends the deadline for filing Form 1120 (Corporate Income Tax Return) from March 15th to September 15th.
- For partnerships and certain other entities, filing Form 7004 extends the deadline for filing Form 1065 (Partnership Return) from March 15th to September 15th.
However, it’s important to note that filing Form 7004 does not extend the time to pay any taxes owed. Taxpayers are still required to estimate their tax liability and pay any taxes owed by the original due date to avoid penalties and interest charges.
