Most returns are being issued within twenty-one days or less. However, some
cases can take longer. The IRS does not go by first in, first out. One thing in particular that is affecting filers
this year is the PATH act. If you claimed the Earned Income Tax Credit (EITC) or Additional Child Tax Credit, those refunds are not said to begin being issued until February 27th, 2018.
You can see more information by reviewing the TurboTax FAQ below
regarding the PATH act. If twenty-one days or more have elapsed and you
are not claiming these credits, I would suggest you contact the IRS
directly so they can investigate your case. You can call 1(800) 829-1040
to reach the general IRS line.
