Authorizes a tax credit for certain railroad expenses

HB 2716 creates a Missouri state tax credit for eligible rail entities to cover certain railroad infrastructure costs. It allows short-line railroads (Class II/III), rail siding owners, or port/city rail authorities to claim a 50% credit against their state tax liability for qualified maintenance, reconstruction, or new rail infrastructure expenses like tracks, bridges, or industrial spurs. The credit is capped annually at $4.5 million for maintenance costs and $10 million for new infrastructure projects, with unused credits carryable for up to five years. Taxpayers must submit a certificate to the Missouri Department of Economic Development detailing eligible expenses and track miles, with credits allocated in the order claims are received if annual limits are exceeded.
