Many Americans are freaking out about getting a smaller tax refund this year — here's why it's happening

I wish I got a smaller refund this year. My effective tax rate increased year over year and I owe for the first time ever despite no changes to income or witholding. If you itemize and you didn't decrease your witholding for last year you are in for a nasty surprise. That bump I'm my paycheck? Yeah get to give it back and then some. Fuck you GOP!
