@CodeGuy - states require tax if your live or work in that state.
If you work in OK, even if you don't live there, you file a "non-residency" tax return. TX does not have state income tax, so there is nothing to file there.
In states where there is a state income tax in both states, it works this way: You pay tax in the state where you work and then file a 2nd tax return in the state where you live. The state where you live will calculate a credit based on the state wher you work, so that you are not taxed by both states on the same dollar of income.

from the OK Department of Revenue website:
WHO IS REQUIRED TO FILE?
- If you live in Oklahoma: Does your gross income earned in Oklahoma or outside of Oklahoma exceed the Oklahoma standard deduction?
- If you don’t live in Oklahoma: Does your gross income generated from Oklahoma meet or exceed $1,000?
If you answered “Yes” to either of these statements, you are required to file an Oklahoma income tax return.
