How to Calculate Missouri Sales Tax
Calculating Missouri sales tax requires combining Missouri’s 4.225% state baseline tax with local city, county, and special district rates before multiplying by the taxable purchase amount.
The Missouri Sales Tax Formula:
Total Combined Sales Tax Rate = MO State Baseline Rate (4.225%) + County Sales Tax + City Sales Tax + Special District Taxes (CID/TDD)
Sales Tax Dollar Amount = Taxable Purchase Price × Total Combined Sales Tax Rate
Final Total Cost = Taxable Purchase Price + Sales Tax Dollar Amount
