If you work in one or more of these income tax-free states (for example: Texas) , but live in a state that does withhold income tax — you'll still need to pay taxes on the money you earned in the tax-free state. You'll claim these earnings on the tax return you file in your resident state. So if you and filing jointly with your husband whose primary residence is in New Mexico, your Texas income is taxable. You would have to file separately to avoid this.
