Provide for a birth day tax credit for the birth of a child

HB 537 proposed creating a new "birth day" tax credit for resident taxpayers in Montana upon the birth of a child. The credit would be up to $3,000, or the total of the taxpayer's Montana income taxes, federal income taxes, and FICA contributions, whichever is less. This credit would be refundable, allowing taxpayers to receive a refund even if they have no state tax liability. The credit amount would be reduced for higher-income taxpayers and capped at $1,500 in certain situations, such as for parents filing separately or unmarried parents sharing custody. If passed, it would have applied to income tax years beginning after December 31, 2025.
