The IRS income tax table is supplied by the IRS every year in the instruction pamphlets on how to fill out you're tax forms each year. The tax tables are broken down into different sections. They are for the different brackets that tax payers fall into. Tax brackets are decided by what type of relationship you are in or if you are not in one. Head of households and married individuals are the least taxed. Single individuals are taxed the most.

In each of these brackets are different amounts of income, broken down in percentage of taxes owed. The individual tax payer can figure their taxes by knowing their adjusted gross income and looking in the appropriate tax bracket and finding their income. This will be on the left hand side. The right hand side will show the amount of the tax owed.

For those Americans that are employed by a business or company, they would have had to fill out a W-4 form before employment started. This informs the employer what amount of your pay should be sent to the federal government to cover the taxes you will owe for each year. If the amount you owe figured by your adjusted gross income is less than the amount your employer took out of your weekly pay then you will receive a refund check. This is the most common. Since taking the right amount of deductions on the W-4 form is set up to withdraw more than is necessary. If you have made adjustments to your W-4 form or your home situation has changed then it is possible you may owe taxes. This is when not enough was taken out of your check weekly and the amount owed is greater that what was withheld. In that case you will have to pay the remainder to the IRS.

The IRS income tax table will assist you in calculating whether you owe or will receive a refund check.
