The Itemizing Threshold at $150K
With a standard deduction of $15,000 (single 2025), you need more than $15,000 in total itemized deductions to benefit from itemizing. At $150K with a $600,000 mortgage: first-year mortgage interest = approximately $41,250. Plus state and local taxes (SALT cap: $10,000) = $51,250 total itemized deductions. Itemizing saves significantly at this income level with a large mortgage.
The $10,000 SALT (state and local tax) cap limits deductions for state income and property taxes to $10,000 combined. At $150K in a high-tax state like California or New York, actual state taxes can be $15,000–$25,000+ — but only $10,000 is deductible. This cap significantly reduces itemizing benefits for high-income earners in high-tax states.
