The bill aims to curb tax advantages for certain property owners and raise revenue via an excise tax while preserving deductions for compliant homeowners — but it increases tax bills for targeted owners, raises compliance burdens, and risks housing-market disruption and reduced rental supply.
Homeowners who are not subject to chapter 50B (i.e., compliant owners) keep access to mortgage interest and owner/rental depreciation benefits, preserving current tax breaks for the majority of ordinary homeowners.
Tax benefits are redirected away from individuals subject to chapter 50B, which reduces opportunities for certain taxpayers to use those benefits as tax shelters and improves tax fairness.
The excise tax on designated excess single-family residences could generate additional federal revenue that could be used for public programs or deficit reduction.
Owners of designated excess single-family residences will face a new excise tax liability if they retain the property, raising tax bills for those owners.
Homeowners subject to chapter 50B lose mortgage interest and rental/owner depreciation deductions, increasing their taxable income and likely raising their tax bills.
The bill increases compliance and enforcement complexity for taxpayers, tax professionals, financial institutions, and the IRS, who must determine excise applicability and chapter 50B liability, raising administrative costs and risk of disputes.

Creates an excise tax on owners who fail to sell certain excess single‑family homes and denies mortgage interest and depreciation deductions for those owners starting after enactment.
Introduced February 27, 2025 by Adam Smith · Last progress February 27, 2025
Imposes a new excise tax on owners who fail to sell certain excess single‑family residences and denies key tax benefits — specifically mortgage interest and depreciation deductions — for taxpayers who owe that excise tax for the year. The changes modify the Internal Revenue Code, borrow definitions from existing tax rules for single‑family residences, and apply to taxable years beginning after the bill becomes law.
