Middle Class Mortgage Insurance Premium Act of 2023

This bill raises the income limit for deducting mortgage insurance premiums on federal income taxes. It increases the cap from $100,000 (or $50,000 for married filing separately) to $200,000 (or $100,000), making the higher limit permanent. The change directly affects middle-income homeowners who pay mortgage insurance and itemize deductions. The provision applies to tax years beginning after December 31, 2021, and modifies Internal Revenue Code Section 163(h)(3)(E).
