Insurance Commissioner Mike Causey, the only Republican elected to the position in Tillis’ home state, agrees. As do cosponsoring Democratic Sens. Adam Schiff and Alex Padilla of California, and Republican Bill Cassidy of Louisiana.

The Disaster Mitigation and Tax Parity Act of 2025, or Senate Bill 336, was first routed to the chamber’s Finance Committee led by Republican Sen. Mike Crapo of Idaho.

Hurricane Helene caused an estimated $53 billion damage in North Carolina, wiping out homes and communities and killing 104. The storm is responsible for 233 deaths in seven states. Areas near Los Angeles were swept by wildfire in January, killing 29, forcing nearly a quarter-million people to evacuate, and damaging more than 18,000 structures.

“By excluding qualified catastrophe mitigation payments from income tax, we are incentivizing property owners to make the necessary improvements that reduce damage and save lives,” Tillis said in a release. “This proactive approach to disaster preparedness not only helps families rebuild faster but strengthens our resilience in the face of future disasters.”

Causey said the grants have direct impact on insurers and claims, a component “critical for ensuring an insurance market that is stable and available and affordable for homeowners.”

“Passing federal legislation that would ensure all state-funded, pre-disaster mitigation grants are tax-free would allow these grants to have the maximum impact,” Causey said.

The North Carolina Insurance Association endorsed the proposal. CEO Gina Hardy said grant money should be free of federal taxation, enabling policyholders to strengthen and improve their homes.

“Qualified catastrophe mitigation payment” as defined in the bill language would be any amount “received for making improvements to an individual’s property for the sole purpose of reducing the damage that would be done to such property by a windstorm, earthquake, flood, or wildfire,” a release says.

President Donald Trump’s first domestic trip after taking office was to North Carolina and California to talk with residents, leaders and see damage.

“Homeowners should not face additional taxes for wanting to protect their homes and our bipartisan legislation will provide the needed tax relief to help affected Americans recover from these disasters,” Schiff said.

Joining the cosponsor list at day of filing Thursday were Republican Sens. Ted Budd of North Carolina, John Kennedy of Louisiana and Roger Wicker of Mississippi; and Democratic Sens. John Hickenlooper of Colorado, Amy Klobuchar of Minnesota, Michael Bennet of Colorado and Jeff Merkley of Oregon.
