Procrastinators may be relishing that they got an extra weekend to file their taxes this year. Thanks to Emancipation Day, an obscure holiday observed Friday in Washington, D.C., the Internal Revenue Service pushed the tax deadline to Monday, April 18. And if three extra days was not enough extra time, Monday is the day to at least file for an extension. Taxpayers would then have until October 17 to file tax returns.

Brad Maione with the New York Department of Tax and Finance said for the first time this year New York taxpayers can only file for an extension online. He said the Department has retired the old paper forms.

"We're trying to get people to use our website more and to reduce the cost of tax administration," he said, adding a reminder that residents still have to pay any owed taxes on time.

Monday is also the last day for people to file federal tax returns from 2007. The IRS said refunds totaling more than $1.1 billion may be waiting for 1.1 million people nationwide, and more than 62,000 New Yorkers, who did not file a tax return for 2007.
