Cause. Hives can also be classified by the purported causative agent. Many different substances in the environment may cause hives, including medications, food and physical agents.

The average American pays almost 30% of their income to taxes. Here's the breakdown. According to the IRS's preliminary data from the 2015 tax year (the returns you filed during 2016), there was a total of $1.454 trillion in income tax owed, which translates to an average effective federal income tax rate of about 13.5% per return.
So combining the federal tax of $2,573, the Social Security/ Medicare of $4,590 and the local and state taxes of $5,400 you would have a total tax bill of $12,563 or 20.9% of income. The typical total tax rate for a family of 4 making $60,000 is about 21%.However given the broad range of tax rates for different state and local governments the rate will vary significantly. With a federal bill of $7,193 and state / local rates from 5% to 13% you are looking at a range of $10,193 to $14,993.otal tax rate for a 'typical' family. I've seen some people overstate their tax bill. People are frequently confused between their top marginal rate and their overall tax burden. If you are in the 25% tax bracket that does NOT mean that 25% of your income goes to the IRS.
