I firmly believe that because of fraud and whatever the IRS is doing to prevent it is the cause of the delay here. It is even stated by the IRS here.

and based upon this IRS calendar, the IRS did not even begin processing returns until 1/25, no matter how early anyone filed.

This is based on facts, and not opinions.
I file on opening day ever year, and have always gotten my return back in less than 10 days. IT was 8 days last year. So based upon this, if the IRS had a 1 week delay (which would make sense) then my return this year would be refunded this week. Which almost has to happen, because me, among millions of other people who filed on 1/19 and before will be hitting 21 days next week and I can only imagine that receiving hundreds of thousands of calls per day from people asking about the status of their returns (and now they have to, or in their words “can” look into it) will cause a ton of added stress and work for them.
So to put it lightly.. If I were the IRS, I would be trying to make damn sure all the people who were accepted on 1/19 and earlier were processed by 2/5/2016.
All in all, it sucks that there is a delay, it has me worried, i am stressing, annoyed and pissed… But the week long delay does add up. Hope this helps calm some nerves, it has made me feel a lil better.
