About.com's Guide to Taxes tells us that "Filing an extension is super easy. I tell you how to do it. But first, let's talk about what an extension is and what it is not. An "Extension" is a way to ask the IRS for more time to file your tax return....However, an extension of time to file is not an extension of time to pay."
So what about filing an extension on your Arizona return? Is it just as easy? Yes, it is.
When is the Arizona Extension Due?Your Arizona individual income tax return, or an extension if you are filing one, is due on April 15th, or the next business day if that falls on a Saturday or Sunday. For the 2012 tax year, your tax return/extension is due by midnight on April 15, 2013 to coincide with a special Federal tax filing date. Arizona personal income tax extensions are allowed for up to six months.
What Forms Do I Need For an Arizona Extension?To apply for a state extension, file Arizona Form 204. If you must make a payment, you still use Arizona Form 204.
If you filed for a federal extension on Form 4868, you do not have to attach a copy of your federal extension to your Arizona tax return. The extension forms will specify the date by which your final return must be mailed.
Why Do I Have To Do All the Calculations If I File an Extension?You must still pay 100% of your tax liability by he original due date of your return (April). If you do not pay 100% of the tax shown on your return with the extension, you will be subject to a late payment penalty. If you do not pay at least 90% of the tax liability disclosed by your return at the time of the extension, you will be subject to the extension underpayment penalty and interest.
