Today is the last the day to file your 2013 taxes if you filed for an extension. Failure to file today will result and in additional penalties and interest. Always know the two most important dates when dealing with income taxes which are : April 15 & Oct.15th. To avoid tax penalties and interest make sure you contact your preparer/accountant and do some tax planning for the upcoming tax season. Tax planning and keeping up with documents and receipts are great ways to avoid rushing and penalties. Not to mention that when you are rushing and your paperwork is not organized there is a bigger chance that your tax preparer/accountant will overlook deductions that could have saved you money.
