Missouri revised statues Chapter 144 section 144.527.1 says "... there shall also be specifically exempted from state and local sales and use taxes defined, levied, or calculated under section 32.085, sections 144.010 to 144.525, sections 144.600 to 144.761, and section 238.235 all sales of farm products sold at a farmer's market." So I didn't have to pay sales tax last year on my farmer's market products, but I did.
