IRS spokesman Dan Boone says people waiting until close to the April 15 deadline should not miss out on earned income tax credits. He said many lower-income workers can qualify.
Some workers who couldn't qualify in previous years may now qualify because of a change in marital status or addition of a child.
A person who worked some part of 2012 and had a household income below $50,270 may qualify.
Boone said there are many IRS-certified volunteers who will prepare and file tax returns for free. The IRS has a toll free number (1-800-906-9887) where callers may see if they qualify for free help and find a location.
