Retail Revitalization Act of 2023 This bill amends tax rules for real estate investment trusts (REITs). It increases (1) the share of equity investments a distressed retail tenant may receive from a REIT from 10% to 50%, and (2) the equity share for regular tenants from 10% to 30%. The bill also allows taxable REIT subsidiaries to accept equity in a retail tenant's businesses as a form of rent, subject to certain restrictions.
