What actually happens
An employee who lives in Oklahoma and performs work in Texas sits in two tax systems at once. The residence state claims the right to tax all of a resident's income wherever earned; the work state claims the right to tax income sourced within its borders. Absent an agreement, both claims stand, and the conflict is resolved after the fact through a credit on the resident return rather than up front in payroll.
Unemployment insurance goes to one state only
Income tax can be split between states. Unemployment insurance cannot. Under the localization test used by every state, an employee whose services are performed entirely in Texas is covered by Texas for unemployment purposes, and all wages are reported there — regardless of where they live, where you are headquartered, or which state's income tax you withhold. Texas's 2026 taxable wage base is $9,000. The four-factor test in order.

Frequently asked
Do Texas and Oklahoma have a reciprocal tax agreement?
No. There is no reciprocal agreement between Texas and Oklahoma. Texas has no wage income tax, so the question does not arise in practice.
Which state's income tax should be withheld?
Oklahoma. Texas imposes no wage income tax, so the residence state's claim is the only one that survives.
Which state gets the unemployment insurance wages?
Texas. Unemployment coverage is never split between states for a single job. The localization test assigns the whole job to the state where services are performed, which here is Texas, regardless of residence or where the employer is headquartered.
