Status
Inferred: no provision found in the saved statute or guide
Primary source (statute, regulation or agency publication saved in full)
Federal backup withholding under IRC 3406 (24 percent on a missing or mismatched TIN) applies in Missouri exactly as everywhere else; this page covers only what the state adds. The 50-state tables put Missouri next to its neighbours, and the Missouri 1099 filing page covers whether the state wants its own copy of the 1099.
Withholding on non-wage payments to nonresidents
What Missouri does not require
State backup withholding
No state backup withholding: RSMo Chapter 143 withholding (143.191 et seq.) covers wages; no backup-withholding provision found
Basis: Inferred: no provision found in the saved statute or guide.
Pass-through entity withholding (out of scope)
Missouri requires withholding on nonresident partners/shareholders of pass-through entities (143.411). Entity-level withholding on distributions to nonresident owners is a duty of the entity, not of a payer, and is not covered on this page.
