What’s in it

The inclusion of this explanation does not constitute agreement with the explanation’s substance by the members of the general assembly. This bill creates a radon mitigation system tax credit (credit) available against the individual and corporate income taxes. The bill defines “radon mitigation system” to mean a system designed to reduce radon concentrations in the indoor air of a building that has been installed. The credit is equal to the amount of the cost to purchase and install the radon mitigation system, not to exceed $1,000. Any credit in excess of the taxpayer’s liability is not refundable but may be credited to the tax liability for the following tax year. The bill applies retroactively to January 1, 2025, for tax years beginning on or after that date.
