How do you file a state tax where one received a W-2 for 3 months Internship Program?

[SGlover16]

My 25 yo daughter who resides in Ohio took a internship position for 3 months in 2021? How do you file her state taxes? Her permanent residence is in Ohio and the internship was in California.

As a CA nonresident, you pay tax on your taxable income from California sources.

If your daughter's  income is more than the amount shown in any of the tables in the link below, she'll need to file a tax return.

CA Filing requirements

As Ohio resident, she'll file resident OH return and pay taxes on all her income but she can claim credit for taxes paid to another state. 

Always start with the non-resident return.
