What it does
This bill creates a new federal tax credit that pays infrastructure bond issuers 28% of the interest they owe on certain municipal bonds. Instead of investors receiving tax-free interest (the traditional municipal bond benefit), the federal government directly reimburses issuers for a large portion of their borrowing costs. This shifts the subsidy from individual bond investors to the bond issuers themselves—typically state and local governments and infrastructure authorities.
Why we flagged it
The bill's core function is to create a direct federal subsidy for municipal bond issuers by paying them 28% of interest costs via tax credits. This is a fiscal transfer mechanism, not a regulatory or structural reform of infrastructure policy.
What the text implies
- The 28% credit is paid by the federal government contemporaneously with each interest payment, creating a permanent annual fiscal obligation that grows with the stock of outstanding bonds—potentially billions annually within a decade.
- By making interest includible in gross income (unlike traditional tax-exempt municipal bonds), the bill shifts the tax benefit from individual investors to institutional buyers and issuers, potentially concentrating benefits among large financial institutions.
