Deductions & credits
Review your Schedule A and Home Mortgage and Interest Worksheet. It is likely due to the mortgage interest.
It is possible the mortgage interest is being limited. Or, if you refinanced your mortgage and took cash out, the interest may not be deductible. Interest is only deductible if the loan was used to "buy, build or substantially improve" the home that secures the loan.
The limit on the amount of interest has changed under the Tax Cuts & Jobs Act. The interest deduction pre-TCJA has been available to qualified mortgage debt up to $1 million ($500,000 married filing separately).
Through 2025, the TCJA has lowered the amount of qualified mortgage debt to $750,000. For qualified mortgage debt incurred on or before December 15, 2017, the $1 million limit remains in place, thus "grandfathering" existing mortgage debt.
