I am sure Texas does not allow a single member LLC
So IF you are the only owner, your options just dropped to two:
S-corp or sole prop. With that, S-corp is the easy answer.
IF you have other partners LLC may be attractive. But since partners is usually NOT attractive, I would lean to S-corp for a one person business in Texas.
It is not a matter of type 'to claim' it is a matter what form to establish. This is something BEFORE the fact, before conducting business.
If you still are questioning which one, offer more information for everyone to help...
