Middle Class Mortgage Insurance Premium Act of 2025

This bill increases the income limit for deducting mortgage insurance premiums on federal income taxes. It doubles the cap from $100,000 (or $50,000 for married filing separately) to $200,000 (or $100,000 for married filing separately) under IRS Code Section 163(h)(3)(E), making the deduction permanent for qualifying taxpayers. The change directly affects middle-income homeowners who pay mortgage insurance premiums and itemize deductions on their tax returns. The policy takes effect for tax years beginning after December 31, 2025.
