What does not change by state
The federal filing rules for each form (who files, the 2026 thresholds, boxes and due dates) are on the federal forms pages; this page covers only what Oklahoma adds. TIN matching, B-Notices, backup withholding and the IRC 6721IRC 6721Internal Revenue Code, Cornell LII penalty are federal. A payee in Oklahoma who gives you a name/TIN pair that does not match IRS records produces the same CP2100 line as one anywhere else, and the same 15- and 30-business-day clocks. State filing is a separate obligation layered on top.
