Do we get back all the interest that we pay off or a certain percentage?
Please provide backup in your answer.

At the end of the year, you will receive a statement from your mortgage company showing the amount of interest you payed on your mortgage for the tax year. This is a deduction from, or a reduction of, your adjusted gross income. It’s not a tax credit. For example, if you made $50K, and your mortgage interest was $5,000 for the year, your taxable income would then be $45K instead of $50K. If your tax rate is 10%, your tax liability, or the amount you owe, would be reduced by $500. You will have to file a 1040 form with a schedule A.

$50,000 x 10% = $5000 tax liablility
$50,000 – $5000 mortgage interest = $45,000 taxable income x 10% = $4,500 tax liability
$5,000 – $4,500 = $500 lower tax liability or what is owed to the IRS.
