What is the sales tax in Missouri?

State rate: 4.225%

The state sales tax rate in Missouri is 4.225%.

Cities, counties and certain districts may also impose local sales taxes, so the tax a seller collects depends on the combined state and local rate at the seller's location.

Repair, installation and labor

The Missouri Department of Revenue says repair labor is not taxable if it is separately stated, while fabrication or production labor is taxable even when separately stated.

Who licenses locksmiths and the trades in Missouri?

From each agency's own page. Check with your city or county for any local license as well.
