2. Missouri — Sales Tax / Business Tax Registration

   Fees for gym memberships are taxable in Missouri as fees to places of amusement, entertainment or recreation (RSMo 144.020.1(2)), but amounts paid for any instructional class are statutorily exempt — significant if you sell classes rather than memberships. Local rates vary by address; use the Missouri DOR sales/use tax rate lookup rather than a fixed local percentage. Register with the DOR (free — the sales-tax bond requirement was repealed in 2018).
