【新唐人2012年9月19日訊】我們來看看美國聯邦政府征收的工資稅和所得稅情況．
工資稅，這部分收入用來支付像社會保險等類福利，另外是收入所得稅，聯邦預算的大部分項目用這筆錢來支付．
2011年，稅收政策中心研究了美國家庭的交稅情況．
53.6％的家庭被征收收入所得稅， 46.4％的家庭不交稅
28.3％的家庭交工資稅，但不交收入稅．
10.3％的是老人和退休人士，他們的社會保險福利不用交稅
收入在2萬美元以下的家庭不交任何稅，這個比例是6.9％
其中只交工資稅不交收入稅的大部分家庭，是因為政府對老人，有孩子的家庭和低收入人士的社會福利．
Who pays US income tax?
The US federal government runs off two kinds of taxes: payroll taxes, which fund benefits such as Social Security, and income taxes, which largely fund the rest of the federal budget.
In 2011, the Tax Policy Center studied the tax liability of US households:
53.6% paid income taxes, 46.4% did not
28.3% paid payroll taxes but not income taxes
10.3% were elderly and retired and were not taxed on Social Security benefits
6.9% did not pay any tax with household incomes of less than $20,000 (£12,300)
The majority of those who pay payroll but not income tax do so because of tax benefits for the elderly, families with children and low-income earners
