<p>The general rule is if you earned income in a state, you generate a filing obligation in that state only on the income that was earned/sourced in that state. </p>
<p>And yes, you wouldn’t report the California earned income on your resident state tax return based on my explanation in the previous statement.</p>
<p>You only need to report as income whatever is mailed to you (W2/1099). I don’t think grants/scholarships are taxable. You’ll have to research that. Taxing a grant would be the equivalent of taxing food stamps.</p>
<p>Also look at the 540NR instructions for the dependency claim question. Should be explained there.</p>
<p>This is my day off! :P</p>
