| You have legally transferred your state of residency from Texas to West Virginia, so for sure you must file a West Virginia state income tax return. Whether you owe money to WV is another matter (see below).
If you work and earn above a certain amount (usually $10,000) in ANY state, that state has the right to tax you on the income earned within their borders. Most states of residence (in your case WV) give you a credit for taxes paid to other states. Often, the credit completely offsets any state tax owed to the resident state.
Temporary workers often avoid the taxes for the state they work in because the employer fails to follow the law and does not withhold the taxes. It's not a big problem as long as the state does not become aware of your work within their borders. When they DO find out, however, there can be some heavy financial consequences for BOTH the employer and the employee. |
