What it does
This bill creates a federal tax credit worth up to 30% of the cost of disaster-mitigation improvements to working waterfront properties—such as elevating structures, installing flood barriers, or stabilizing shorelines—capped at $300,000 per taxpayer per decade. The credit applies to businesses with under $47 million in annual revenue that depend on water access (fishing, boatbuilding, aquaculture, etc.), and is designed to help small waterfront operators afford climate and flood resilience upgrades.
Why we flagged it
The bill's core mechanism is a targeted tax credit for disaster-mitigation capital investment by small waterfront businesses. It is functionally a subsidy for climate adaptation infrastructure, not a broad tax relief measure or corporate giveaway.
What the text implies
- The credit may incentivize waterfront development in high-risk flood zones by reducing the cost of mitigation, potentially increasing long-term exposure to catastrophic loss if mitigation fails or climate risk accelerates beyond design standards.
- The $47 million gross-receipts threshold is indexed to inflation only after 2026, creating a multi-year window where larger regional operators may qualify; the threshold's future trajectory is unclear.
