I know some people get upset about getting smaller refunds, but it's good to remember... your tax liability is your tax liability. Because you are getting less (or paying) doesn't mean that you're paying more in taxes. It just means that the government didn't have free use of as much of your hard-earned money. In fact, if you owe, it means you got to use some of the government's money for free over the course of a year.
I just think that sometimes when people get smaller refunds they think, "I'm getting cheated out of money that belongs to me." That's not the case... you need to pay whatever that amount is, no matter what.
Personally, I would rather the government not get to keep any of my money throughout the year.
