After calculating the AGI, there are two options. You can either subtract a standard deduction, or subtract itemized deductions, whichever is greater. Some examples of itemized deductions might include some medical and dental expenses, interest on home mortgages, charitable contributions, state and local taxes and casualty losses.

What tax bracket you fit in depends upon your income and your marital status.
