October 15th marks the IRS tax deadline for E-filing tax returns. The trend for E-filing tax returns has swept the US due to the convenience of not having to file paperwork and receiving your tax refund faster. You will still be able to mail in your 2008 tax return after the October 15th E-File deadline, but your return will be considered late.
The tax extension deadline means that any individual taxpayer who has filed an extension for the tax year 2008 must have their returns completed and postmarked on its way to the IRS by 11:59PM on October 15, 2009 in order to avoid penalties. If you owe for the tax year 2008 and you miss this deadline, penalties will be added to the amount that you owe, and interest will continue to accrue. If you do not have the transcripts or documents needed from your employers or past years, it would be wise to Retrieve Missing Forms right away and get the ball rolling on your taxes before the tax extension deadline.
A deadline of October 15th means that the beginning of October will be filled with taxpayers attempting to have their returns completed and filed with the IRS before the tax extension deadline. It would be in your best interest to file as soon as possible so that you do not miss this deadline.
