Tax time is here for U.S Residents.  If you have not got it done, you had better hurry.  You can get it done quickly online at various sites such as CompleteTax.  CompleteTax cost you $9.99 for simple taxes, Single or Married with no Kids.  If that does not fit your situation it will cost you $29.99.  All online, e-filed and your done.  Need more time check out blog posting about getting more time with FileLater, or check out FileLater at savingsheadquareters.com. 
For Canadians you still have 15 days.  I suggest you use QuickTax, easy and cheap.  If your a student its free.  Prices start at 14.99 and you only pay when you print and file.  You can see your return before you decide if you want to file using QuickTax, at no cost.
