How do I get an extension to file my taxes?

What the Code allows

• The IRS may grant a reasonable extension of time to file a return. Except for taxpayers who are abroad, an extension cannot be longer than six months.

The part people miss

• An extension of time to file is not an extension of time to pay. The addition to tax for paying late is measured from the payment due date, unless you also have an extension of time to pay.
• Filing late without an extension carries a separate, larger addition to tax, unless the delay was due to reasonable cause and not willful neglect.

What it turns on

• whether you can pay what you owe by the original due date
• whether you are abroad

What would make it not apply

• you treat the extension as more time to pay
• you need more than six months and are not abroad
