Of the 204,000 Maine federal income tax returns filed as of Feb. 25, 72 percent were e-filed, up from 67 percent during 2004. While the percentage typically declines as April 15 approaches, the IRS expects for the first time to have more than half of all individual tax returns filed electronically. The growth of e-filing comes as record tax refunds are being sent to taxpayers. The average refund so far is $2,436 – a record amount and more than $200 more than last year. The IRS is also seeing record numbers of people using direct deposit for their refunds. More than 29 million have selected direct deposit, up 4 percent from last year. So far this year, three out of four taxpayers receiving refunds have used direct deposit.
