If you was a non-resident of CA for all year - you will be responsible for taxes for income from CA sources only.
You will not receive a credit from CA for taxes paid to other states.
You will receive a credit for local taxes paid outside Indiana - see page Schedule 1 on the page 27 - http://www.in.gov/dor/taxforms/06pdfs/06-it40bk.pdf
You may claim this credit if are filing as a part year resident of CA - http://www.ftb.ca.gov/forms/06_forms/06_540s.pdf
Assuming you had income from Indiana for the same time and paid Indiana state income tax as a non-resident - you should allocate Indiana income and Indiana taxes to the time you was a resident of CA and to the time your was a resident of IN - this income is not separated on your Indiana tax return.
The Indiana income for the time you was a resident of CA is reported in the Part I and the Indiana income tax for the time you was a resident of CA is reported on the 7 Ca Schedule S.
You may prorate based on the time the income was received or based on the time of residency. For instance, your total Indiana income was $30,000 and total Indiana tax amount - $1500. Your was CA resident for 150 days and IN resident for the rest of the year. Your Indiana income and taxes would be allocated as 150/365 = 41% and 59%.
You actually stated above - "I was a part year non-resident of Ca"
In my understanding - this mean that you was part year resident and part year non-resident. Please clarify.
there is no such status as "part year non resident of Ca"
We need to clarify these issues before moving further...
Residents of California may claim a credit only if the income taxed by the other state has a source within the other state under California law.
No credit is allowed if the other state allows California residents a credit for net income taxes paid to California. Nonresidents of California may claim a credit only for net income taxes imposed by and paid to their states of residence and only if such states do not allow their residents a credit for net income taxes paid to California.
As a resident of Indiana you are you will receive a credit for local taxes paid outside Indiana - see page Schedule 1 on the page 27 - http://www.in.gov/dor/taxforms/06pdfs/06-it40bk.pdf and you are not allowed the California credit for the income taxed paid to the other state.
I am not referring to you as a CA resident - the credit you were asking for is mainly for CA residents.
California nonresident individuals, estates, or trusts that are residents of one of the following states or U.S. possessions and paid a net income tax to that state or U.S. possession on income that is also taxed by California may claim the other state tax credit: Arizona, Guam, Indiana, Oregon, and Virginia. Note: California nonresidents who are residents of any state or U.S. possession not listed may not claim this credit.
As the income from CA is taxable in Indiana - you should allocate Indiana income taxes to the CA income - this amount is not separated on your Indiana tax return. You may prorate based on the total income and CA income. For instance, your total income was $30,000 and CA income $4500 - that is 15%, If your total Indiana tax amount is $2000 - the Indiana taxes allocated to CA income will be $2000*15%=$300.
