But the story is more complicated than the size of a tax refund - investigators from the Government Accountability Office warned last year that millions of Americans had not changed their tax withholding to synch up with the new tax laws - and some of that will mean a tax filing surprise before April 15.
The reason for that surprise is that the Internal Revenue Service altered the tax tables - the amount which employers hold out of your paycheck and send to Uncle Sam - in an effort to speed even more money to workers.
When less money is being withheld from your paycheck, that can mean in some instances that you aren't paying enough to the IRS, which can result in either a smaller tax refund - or in some cases, the need to pay a tax bill to the IRS.
Thus, it's possible you could pay 'less' in taxes overall, but still see a smaller tax refund.
But some of the Twitter responses to the Treasury Department tweet indicated a difference of opinion.
"Who yeah gunna believe? Your ‘lying’ bank account or the US Treasury?" tweeted @MTorganizer. "I think we all know what the bottom line on our tax return says!"
"I think I know what my tax return says," wrote @Tatortots2003. "That was a huge loss for my family."
