Sales & use tax
Brentwood's combined sales tax rate is 9.738% (use tax 6.225%), jurisdiction code 08236-189-000, per the Missouri Department of Revenue's Jurisdiction and Total Rate Database for the fourth quarter of 2026. The same table lists 5 smaller rate areas inside the city where special taxing districts (community improvement and transportation development districts among them) add tax, at a combined sales rate of 10.738%. Missouri's own state rate is 4.225%; the rest is local. For a re-roof, 12 CSR 10-112.010(1) provides that "a contractor is the final user and consumer of the materials and supplies used and consumed in fulfilling a construction contract and which become part of a completed real property improvement," so the roofer pays tax when it buys the materials. Under 12 CSR 10-112.010(2)(A), "In general, title passes after installation is complete," and where title passes after attachment the contractor "does not collect tax on its transfer of ownership or title of the item."
