1. You Moved Mid-Year

You may need to indicate that you were just a part-year resident of that state.

2. You Work In Another State


If you work in one state and live in another, then your taxes will need a little extra attention. "You could be be a resident of California who does contract work for a company in Georgia," according to the US Tax Center at"Whether you briefly traveled to a different state for work, or you work remotely from home, make sure to get your refund status for that state this tax season."

And if it's in another state, then you will probably need to file taxes for that state, too.

6. You're Telecommuting


Even if you perform all of your duties in a virtual office, your real-life taxes might cross state lines. As Cara Griffith said in Forbes, "an employee may telecommute from State A but report to State B. In most instances, the employer will have to withhold from State A because that is where the services are performed." Yes, the tax laws are no easier for people who work via the internet.
