Some federal income tax refunds may be temporarily delayed
In general, you can expect your federal refund to be issued approximately 21 days after your electronically filed tax return has been accepted. However, identity theft is still a major problem, and the IRS continues to implement new strategies to protect taxpayer data. For example, if you claim the Earned Income Tax Credit or Additional Child Tax Credit on your 2016 individual federal income tax return, your refund will be held until February 15.
