Under TCJA, mortgage interest is deductible if the home acquisition debt is $750,000 or less ($375,000 for married filing separate) on one or two homes for 2018 through 2025. Debt incurred on or before December 15, 2017 is grandfathered in under the old rules for home acquisition debt of $1 million or less.
