There are several different tax brackets and tax rates for married taxpayers for the year 2014, including Married Filing Jointly and Married Filing Separately, states Investopedia. There is no filing status for Married, Head of Household. However, there is a separate filing status of Head of Household. This status also has several tax brackets for a number of different tax rates.
A federal tax bracket determines the income tax rate for each taxpayer, explains Investopedia. There are seven tax rates for the tax year 2014, and they all correspond to different levels of income, depending on the filing status of taxpayers. A taxpayer can file as single, married filing jointly or separately, filing as a widow/widower, or filing as head of household.
The United States has a progressive tax system that results in a higher tax rate for higher income, states Investopedia. Each tax rate applies to certain levels of a person's income, rather than to all taxable income of that person. For example, in the 2014 income tax year, a Married Filing Jointly taxpayer who earns $70,000 does not pay a 15 percent tax rate on the entire $70,000. The taxpayer pays 10 percent on the first $18,150 and 15 percent on the amount between $18,150 and $70,000.
