What interest is deductible?

For tax year 2023, the limit remains at $750,000 ($375,000 for married filing separately) of debt secured by your first and second home for binding contracts or loans originated after December 16, 2017. For loans prior to this date, the limit is $1 million.

The new tax law suspends the deduction for home equity interest, unless the loan is used to "buy, build or substantially improve" the home that secures the loan.
