Homeowners can deduct mortgage interest and real estate taxes from their taxable income, potentially reducing their tax liability. This calculator helps you determine how much you can save by claiming these deductions.
How Mortgage and Real Estate Tax Deductions Work
The Internal Revenue Service (IRS) allows homeowners to deduct mortgage interest and real estate taxes from their taxable income. These deductions can significantly reduce your tax bill, especially if you itemize your deductions.
Mortgage Interest Deduction
You can deduct the interest you pay on your primary residence mortgage. The IRS limits this deduction to $750,000 for mortgages obtained after December 15, 2017. For mortgages obtained before that date, the limit is $1 million.
Note: The mortgage interest deduction is only available if you itemize deductions on your tax return. Standard deductions do not allow for this deduction.
Real Estate Tax Deduction
You can also deduct the real estate taxes you pay on your primary residence. This deduction is not limited in the same way as the mortgage interest deduction, but it is subject to the same itemized deduction rules.
Formula: Tax Savings = (Mortgage Interest + Real Estate Taxes) × Tax Rate
Combined Deduction
When you combine mortgage interest and real estate tax deductions, you can potentially save a significant amount of money on your tax return. The exact amount you save depends on your mortgage interest, real estate taxes, and your tax rate.
| Scenario | Mortgage Interest | Real Estate Taxes | Tax Rate | Potential Savings |
|---|---|---|---|---|
| Low Income | $5,000 | $2,000 | 24% | $1,680 |
| Medium Income | $10,000 | $4,000 | 24% | $3,360 |
| High Income | $20,000 | $8,000 | 24% | $6,720 |
Worked Examples
Let's look at a couple of examples to illustrate how the mortgage and real estate tax deductions work.
Example 1: Low Income Homeowner
A homeowner with an annual mortgage interest of $5,000 and real estate taxes of $2,000 in a 24% tax bracket can save:
$5,000 (Mortgage Interest) + $2,000 (Real Estate Taxes) = $7,000
$7,000 × 24% = $1,680
This homeowner can save $1,680 on their tax return by claiming these deductions.
Example 2: High Income Homeowner
A homeowner with an annual mortgage interest of $20,000 and real estate taxes of $8,000 in a 24% tax bracket can save:
$20,000 (Mortgage Interest) + $8,000 (Real Estate Taxes) = $28,000
$28,000 × 24% = $6,720
This homeowner can save $6,720 on their tax return by claiming these deductions.
