Federal infrastructure credit masks permanent bank tax break buried in bill

What it does

This bill creates a federal tax credit for state and local governments that issue infrastructure bonds, paying them 42–30% of each interest payment directly from the Treasury. It also expands rules allowing small financial institutions to hold more tax-exempt bonds without triggering federal interest-deduction limits. The primary beneficiaries are state/local issuers (who pay less to borrow) and banks (who can hold larger tax-exempt bond portfolios), while the cost falls on federal taxpayers.

Why we flagged it

The bill's operative mechanism is a direct federal subsidy to municipal bond issuers (Section 6436) paired with a permanent expansion of tax-exempt bond holdings for small banks (Section 265). The infrastructure framing masks a dual-beneficiary structure: public issuers receive interest-payment credits, while private financial institutions gain expanded tax-arbitrage capacity.

• Section 4 (small-issuer exception expansion from $10M to $30M) is substantively unrelated to infrastructure bond financing; it benefits bank tax-exempt bond portfolios independent of infrastructure projects.

What the text implies

• The 42% interest-payment credit (2026–2030) creates a permanent federal subsidy stream: Treasury pays issuers directly, reducing municipal borrowing costs but creating an open-ended fiscal commitment with no sunset or aggregate cap.
• Section 265 expansion allows banks to hold $30M (vs. $10M) in tax-exempt bonds without triggering federal interest-deduction limits—this is pure tax arbitrage: banks capture the tax-exempt yield spread without corresponding public benefit or federal offset mechanism.
