The Missouri House passed HB3231 on March 27, creating innovation districts with a 25% tax credit on office-to-residential conversion costs capped at $50 million annually, and an employer retention credit allowing qualifying businesses to retain up to 3% of state income tax withholdings if they stay in a designated district for five years at 95% of baseline payroll. The employer retention credit creates a state-level tool for anchoring commercial tenants in converting corridors — something no existing Missouri BID or CID enabling statute provides. The bill moves to the Senate. See Formation Intelligence RW·1·1·3 for the full formation process analysis.
