I am a nevada resident, but work in California. I paid 803 dollars to California State income tax, but my California refund shows 101 dollar refund. why not 803?

It depends.  However, even though you do not live in California, you still must pay tax on income earned in California as a nonresident.  Therefore, depending on your total income, you may have made enough money in California for them to have taxed you through the year.  It is true that in Nevada you do not pay tax on that income, but California can tax you.

Here is a California Tax Board website that provides more information:  https://www.ftb.ca.gov/individuals/filertn/nonresidents-part-year-residents.shtml
