When should I be paying state rental taxes?

[Nicholas Sheridan, Jr.]

Hello good people of BP, 

I am having a difficult time finding info on when I am supposed to be paying taxes on my rental income in Missouri. Both properties are owned by a single member LLC and I was under the impression this is pass through income that you pay tax on every year when you file your state return. The only info I could find is regarding employers from the State of Missouri Employer's Tax Guide. Thank you for the help!
