Typically when you file an extension with the IRS it is for 6 months, meaning that your return would be due on or before October 15th, 2008. However, before you begin preparing your return, double check to make sure that you filed a 6-month extension. And you must have filed the extension prior to or on April 15.
Also, if you owe a federal liability, you will also likely have to pay additional penalties. When you filed an extension, you were granted an extension in the deadline to file a return, not to pay your tax liability. To avoid the penalties, you must have included at least 90% of what you expect to owe at the time of filing your extension or before April 15.
Most tax preparation offices are open extra hours around the October deadline, and many CPAs and accountants also prepare for the rush of “late filers.” If you need help preparing your return, feel free to check out our locations page to find a tax preparer near you.
