I was a college student (and worked) in California but a resident of Idaho until June, then became a resident of California. Do I need to file taxes in both states?

I was previously a dependent in Idaho until 2015, and I'm now filing as independent.

If you had sufficient income to meet each state's filing threshold, you will need to file tax returns with both states.

You will want to file an Idaho part-year resident return. You should be able to obtain a tax credit on the portion of your California income earned while an Idaho resident, to offset the burden of double taxation.

Your tax situation in California is actually a bit more complicated, and may require the filing of two returns, as your were a non-resident for the beginning of the year, and a part-year resident once you assumed California residency. You may wish to consult the California Franchise Tax Board to determine the best way to file. http://www.taxes.ca.gov/Income_Tax/index.shtml
