SB 608 - This act creates an earned income tax credit to be taken against Missouri income tax liability. The tax credit is nonrefundable. For taxable years beginning on or after January 1, 2008, the amount of the tax credit will be equal to five percent of the allowable federal earned income credit. Every two tax years, the amount of the credit is doubled such that for tax years beginning on or after January 1, 2012, the amount of the tax credit will equal twenty percent of the allowable federal earned income credit. The Department of Revenue is required to notify taxpayers which would qualify for the credit. This act will automatically sunset six years after the effective date of the act unless reauthorized.
