Modifies the "circuit breaker" tax credit by increasing the maximum upper limits and adjusting the property tax credit income phase-out increment amounts

HB 45 modifies Missouri's "circuit breaker" property tax credit by increasing the maximum credit amount and adjusting how income thresholds phase out eligibility. It directly affects Missouri homeowners aged 65+, disabled veterans, or disabled residents who pay property taxes on their primary residence. Key changes include raising the income limits for qualifying and modifying the step-by-step income reduction increments, making the credit accessible to more households within the program's framework. The bill does not expand eligibility categories but adjusts existing rules to provide greater relief for moderate-income residents facing property tax burdens.
