A bill for an act creating a radon mitigation system tax credit available against the individual and corporate income taxes, and including retroactive applicability provisions.

HF 211 creates a new tax credit for individuals and corporations that install radon mitigation systems in buildings. The credit is equal to the cost of purchasing and installing the system, up to a maximum of $1,000, and can be applied against state individual and corporate income taxes. Any portion of the credit that exceeds a taxpayer's liability for the year is not refundable but can be carried over to the next tax year. This bill applies retroactively to tax years beginning on or after January 1, 2025.
