Businesses in Oklahoma only collect tax for the state of Oklahoma. The burden is if 49 other states can ask a business in Oklahoma to collect tax for them. Trust me, the folks in California would love to collect income tax from you next.
I think Oklahoma would be happy for the Oklahoma resident purchases to have sales tax applied. And I think California would be happy for the California resident purchases to have sales taxes applied...
I don’t think too much more than that is going to happen...
