According to a new MSN(R) Money survey conducted by Zogby Interactive, 39.6 percent of the Americans surveyed said they have not yet filed their taxes. The survey, which examined tax handling habits among 5,147 Americans between April 2 and April 4, 2007, further revealed that half of Americans are preparing their taxes themselves and that 55 percent are filing online.

The survey also showed that two weeks before the federal filing deadline of April 17, many more young Americans had filed their taxes than their parents' generation. At the time of the survey, nearly three out of four of those surveyed between the ages of 18 and 29 had already filed their taxes, while only 49.8 percent of those between the ages of 50 and 64 had filed.

In addition, the study found that those who have grown up with the Internet are filing online more than people in older age groups are. Nearly two-thirds of surveyed taxpayers age 18 to 29 are e-filing, while only 44.9 percent of those ages 50 to 64 are filing online. Those from older age groups were also much more likely to hire an accountant than younger age groups were.
