After you file

21 days is not a magic number.   The IRS will not give any commitment at all for 2014.   They said in 2013 that *most* refunds were processed within 21 days, but that is just an average - some are faster and some take longer.  They are really looking closely for possible fraud this year.   They have also said that due to budget cuts up to 50% of all calls to the IRS will not be answered and to expect delays with processing refunds.
