According to the IRS, more than 73 million people filed their IRS tax forms using e-File, the IRS' Internet-based method to file tax returns in 2006. Most home software tax preparation packages include information and processes on e-filing. Some packages include the service for free, others charge, and still others charge but offer a rebate for low- or no-cost tax filing. If you have a tax professional prepare your taxes, most will now file tax returns using e-File if you request it. For information on how e-file works, visit IRS.gov. For information on software-specific e-File options, check the documentation that came with the software or contact the software manufacturer.
