HI SB2431

Creates a tiered, nonrefundable tax credit for insurers offering federally qualified health savings account (HSA)-eligible high deductible health plans (bronze and catastrophic plans) in Hawaii, with higher credit amounts for plans written in rural and medically underserved areas.

Requires qualifying insurers to match a policyholder's first-time contribution into a health savings account up to a specified dollar amount as a condition of receiving the tax credit.

Limits the total tax credits any single insurer can claim per taxable year, with unused credits carrying forward to subsequent years; all claims must be filed within five years of the taxable year.

Applies to taxable years beginning after December 31, 2025, with the Act effective July 1, 2050, and automatically repealing on December 31, 2030.
