New York Mortgage Interest Deduction
New York Mortgage Interest Deduction 2026
New York homeowners should separate federal mortgage-interest rules from the New York itemized deduction calculation. IRS Publication 936 controls the federal Schedule A mortgage-interest workflow, while New York says residents may itemize for state purposes whether or not they itemized federally and points filers to IT-196 instructions for state itemized deductions.
