Modifies the senior citizen property tax relief credit or circuit breaker tax credit by expanding the eligibility criteria and increasing the maximum income limit and the property tax credit amounts

HB 1430 expands Missouri's senior property tax credit by raising the income limit for eligibility and adding new qualifying groups. It increases the spouse income exemption from $2,000 to $20,000 (effective 2026), expands disability eligibility to include veterans with 100% service-connected disability, and adds surviving spouses receiving Social Security benefits. The credit, based on property taxes paid on a primary residence, requires new documentation for disability or veteran status but removes barriers like needing prior employment. This change would allow more seniors, disabled residents, veterans, and surviving spouses to qualify for tax relief on their home payments.
