Q.09Are the Mortgage Tax Savings results financial advice?
No. Estimates only. You save tax only if you itemize and your itemized deductions exceed the standard deduction. Interest is deductible on up to $750,000 of mortgage debt ($375,000 if married filing separately); this estimate applies the $750,000 limit, so married-filing-separately filers with a loan above $375,000 will see an overstated saving. Results also depend on filing status and state law. This is not tax advice — consult a tax professional.
