Many states have Earned Income Tax Credit provisions in their income tax laws. Uniformly these are expressed as a percentage of the federal EITC, but sometimes with differing eligibility restrictions. Here is a table showing the state EIC provisions in TAXSIM as of October 2017, which should be current through the calendar 2016 tax year.
Minnesota has a "Working Family Credit" similar to the EITC but with a different structure. It didn't fit in the table below, but is documented here.
Please write to me if you see any incorrect entries.
