You've sent off your 2015 tax return to the IRS, enclosed a check or asked for a refund, and crossed taxes off your to-do list for the year.
But you're not done yet.
Americans will still have to work until April 24 to earn enough money, on average, to pay what they collectively owe Uncle Sam this year, according to the Tax Foundation, a tax policy research group.
Some will get off relatively easily, though, and others will have to work even longer to make enough to pay what they owe in taxes. When you factor in what you pay in state and local taxes, a lot depends on where you live.
A taxpayer in Louisiana, where the tax burden per person is among the lowest in the country, will have earned enough, on average, to have paid their tax federal, state and local bills by April 2. In New Jersey and Connecticut, two of the highest-taxes states per capita, you'll have to keep working until May 13 to earn enough to pay your taxes.
