In some states, residents have to work days longer than in others before they start working for themselves — rather than to pay their taxes.

So-called Tax Freedom Day is the day when the nation as a whole has earned enough money to pay its federal, state and local taxes. This year, Tax Freedom Day falls on April 24, and it’s the day in which we’ve earned enough to foot our $4.99 trillion 2016 tax bill (that’s 31% of the national income), according to the Tax Foundation, a nonpartisan tax research organization.
