The Internal Revenue Service announced Tuesday that taxpayers will have until April 18 to file their returns because of a holiday on April 15.
Emancipation Day, a holiday observed in the District of Columbia, will fall on Friday, April 15 and, by law, District of Columbia holidays affect tax deadlines in the same way as federal holidays, giving taxpayers three extra days to file this year.
Taxpayers requesting an extension will have until Oct. 17 to file their 2010 tax returns.
The IRS had previously announced that it wouldn't be ready to process returns with itemized deductions until mid- to late February because tax changes enacted by Congress at the end of the year required some reprogramming.
