Once you complete your 2007 federal tax return, you can either file it electronically or mail it to the IRS.

More than one-half of all taxpayers file electronically because they know that IRS e-file provides a fast, easy, accurate, secure and convenient way to file. Taxpayers who file electronically receive an acknowledgement that their return has been received and accepted for processing.

Electronic options include:

• Computer filing using an authorized IRS e-file tax professional
• Using your personal computer to file
• Free File is available at IRS.gov for many taxpayers as an option for filing their returns with no charge

If you choose to mail your return, you will find directions on where to send it on the back cover of your instruction booklet.

When mailing your return, whether enclosing a payment or not, use the envelope and the appropriate mailing label that came with your tax instruction booklet. If you moved during the year, check the tax package to find the mailing address of the appropriate IRS Center. The appropriate address depends on where you live and whether or not you are enclosing a check or money order. Checks or money orders should be payable to the "United States Treasury."
