In addition to the information provided previously, there is an income phaseout for claiming mortgage interest. SEE BELOW:
If you have an adjusted gross income of over $166,800, your mortgage interest starts to get phased out. For every $100 of income over $166,800 you lose $3 of itemized deduction X 33.3% up to a maximum loss of 80 percent of your itemized deductions. Talk about another overly complicated rule the IRS/government has implemented!
Example: You make $266,800 and you have $50,000 in mortgage interest deductions. Take $266,800 – $166,800 = $100,000. Then take $100,000 X 3% = $3,000. Finally, take $3,000 X 33.3% = $999. You can now only deduct $49,001 ($50,000 – $999) from your income instead of originally $50,000.
