One third of all U.S. households, 75% of households with more than $75,000 income and most homeowners itemize their deduction on their federal income tax returns. It makes sense because the interest paid on their mortgage and their property taxes probably exceeds the allowable standard deduction.
However, with interest rates as low as they have been in the last two years and the price of homes having come down considerably, it is possible that the standard deduction may be the better choice.
Each year, the taxpayer can compare the total of the itemized deductions to the standard deduction to select which method will result in the most benefits. The 2011 standard deduction is $11,600 for married couple filing jointly and $5,800 for single filers
