WASHINGTON -- The Internal Revenue Service says 660,000 taxpayers will have their refunds delayed by up to six weeks because of a problem with the software they used to file their tax returns.
The delay affects people claiming education tax credits who filed returns between Feb. 14 and Feb. 22.
The IRS expects to process about 150 million tax returns from individuals, so less than 1 percent will be affected. About 6.6 million taxpayers are expected to claim the education tax credits.
The software problem was on Form 8863, which is used to claim the American Opportunity credit, which provides up to $2,500 to help pay for college expenses, and the Lifetime Learning credit, which provides up to $2,000.
The form includes a series of questions. On some of the questions, if the taxpayer answered "no," the answer was left blank when the form was electronically transmitted to the IRS.
H&R Block said the forms were filled out correctly but the answers were dropped when the forms were transmitted to the IRS.
The IRS has long had a goal of increasing the number of people who file their tax returns electronically. The agency promises faster refunds for people who file electronically and have their refunds deposited directly into bank accounts.
In 2012, nearly 120 million taxpayers electronically filed their federal tax returns with the IRS. That’s about 81 percent of all individual returns.
