I use TurboTax, and have for years. They are now owned by Intuit, makers of Quicken/Quickbooks. You can file for free if you have a very simple tax filing status, or you can opt for the non-free versions that will ask more detailed questions and handle multiple incomes and income types. It stores everything online after you are done, and you can download/print the documents if you like. If you don't care, you can always go back to their site and pull up your tax paperwork for previous years. Highly recommended, unless you have a complicated tax situation. In that case, hire a professional to make sure you are filing correctly.
