Long-term specified asset designation: HUDCO bonds qualify, with proceeds restricted to self sustaining infrastructure projects. Bonds issued by the Housing and Urban Development Corporation Limited (HUDCO) and redeemable after five years, if issued on or after 1 April 2025, are designated as a long-term specified asset under the income tax reinvestment provision; HUDCO must apply proceeds only to infrastructure projects able to service debt from project revenues without dependence on State Governments, with 'infrastructure' defined by the Updated Harmonised Master List of Infrastructure sub-sectors and its amendments.
