FiveThirtyEight:

Americans hate filing tax returns, but they love getting refunds. More than three in four taxpayers get refunds, and the average amount they get back is close to $3,000, according to IRS data. That means that for many Americans, their annual refund is the biggest single check they’ll get all year.

But if you’re among the millions expecting a payout from the IRS this spring, make no mistake: That money was yours all along. Getting a refund means you paid too much in taxes last year and the government is paying that money back — without interest.

I’m no tax expert but I’ve always told people they should work their taxes so they get the smallest refund possible. Otherwise, you’re just giving the government an interest free loan of your money.
