When Itemizing Wins in 2025
Itemizing typically wins if you have: (1) a large mortgage (first year mortgage interest on a $500K+ loan is $30,000+), (2) significant charitable contributions above your typical amount, (3) high unreimbursed medical expenses. Most people with mortgages under $300,000 don’t exceed the standard deduction even with mortgage interest + SALT cap ($10,000).
If your normal annual giving is $5,000 (below the itemizing threshold as a single filer), consider giving $10,000 every other year instead. In the giving year: $10,000 (charitable) + $10,000 (SALT cap) = $20,000 itemized deductions > $15,000 standard. You itemize in one year and take the standard deduction the other, maximizing total tax savings over two years.
