why is my new york mortgage interest and points deduction amounts lower than the federal amounts

New York State has different rules for itemized deductions compared to federal tax laws. Since 2018, New York has decoupled from certain federal tax changes, meaning it follows older federal rules for deductions.

For mortgage interest and points deductions, New York does not apply some of the limitations introduced by the federal Tax Cuts and Jobs Act (TCJA). However, other factors—such as state-specific deduction limits or differences in how deductions are calculated—could result in lower amounts compared to your federal return.
