What Is a Tax Extension?
A tax extension gives you additional time to file your income tax return. Instead of the standard deadline (usually April 15), an approved extension allows you to file your return later—typically up to six extra months.
However, it’s important to understand that:
- A tax extension only extends the filing deadline
- It does not extend the payment deadline
- You must still estimate and pay any taxes owed on time
