Using Free File software
If your income qualifies you for Free File software, go to IRS.gov/freefile. Explore the various software brands and choose the option that's right for you. You'll then be directed to click to go to the company's website.
You'll need to have a copy of your last tax return handy, along with your W-2, any receipts for charitable donations and any other documentation of your income and deductions.
Never used tax software before? It's incredibly easy and goes step-by-step through your return by asking a series of questions to fill in all of the blanks. At the end of the process, you file your return eletronically.
The IRS says you save time and will get your refund faster, particularly if you opt to have the money direct-deposited into your bank account.
