This basically means that the first four months of the year you're only working to pay all your taxes. You can check it out at CNN for more information, they also provide numbers on a state-to-state basis. People in Oklahoma and Alabama only have to work 102 days for the government, people in Connecticut pay significantly more taxes and have to work 140 days to pay all taxes. For New York it's 136, California 127 and Florida 122.
Breaking that 120 days down, the Tax Foundation estimates it will take:

43 days of work to pay off federal, state and local income taxes 30 days to pay off payroll taxes (for Social Security and Medicare) 16 days to pay off sales and excise taxes 14 days to pay off corporate income taxes (This assumes that a tax on a business is passed on to its customers, employees and shareholders in terms of higher prices, lower paychecks and less shareholder value.) 12 days to pay off property taxes 4 days to pay off other taxes (e.g., customs duties) 1 day to pay off estate and gift taxes
