No extension to pay tax
An extension of time to file does not give you more time to pay your tax. If you believe you will owe money when you file, you should include the amount you think you will owe with your extension. You can pay what you owe with your extension in any of the following ways:
- Direct debit of your bank account
- Mailing a check
- Via the IRS and/or state website payment pages
