Here's who gets hit hardest at tax time

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.

This year, the group estimates that Americans will pay $5 trillion on federal, state and local taxes — or about 31 percent of the nation's income.

To be sure, individual tax burdens can vary widely, depending on how much you make and how you earn your living. Some taxpayers will work well into the summer before they've made enough to pay their taxes. Others, including those who qualify for an earned income tax credit, were likely done before the groundhog saw his shadow.

Residents of Connecticut pay the highest federal, state and local taxes in the country — some $7,869, on average, per person, according to the latest data from the Tax Foundation. (That's likely because the state also had the highest per-capita income at $64,864.)

Here's a closer look at where you federal tax dollars go.

Your tax burden also comes in many different forms, depending on your state's tax structure. In Oregon, for example, some 40 percent of the state's revenues come from individual income taxes. Seven states (Alaska, Florida, Nevada, South Dakota, Texas, Washington and Wyoming) collect no income tax. But those states lean more heavily than others on sales and property taxes to pay government expenses.

At the federal level, individual income taxes make up the largest share — nearly $1.4 trillion — of Uncle Sam's revenues. Social Security and corporate taxes are the next biggest categories.
