Resident status Rules
You’re a resident of California for tax purposes if your presence in California wasn’t temporary or transitory in purpose. Generally, you’re a resident if you lived in California, even if you were temporarily out of state.
Here are some examples of situations that can make you a California resident for tax purposes, according to the state:
You spend more than nine months in California during the tax year.
Your employer assigns you to an office in California for a long or indefinite period.
You decide to check out California for a while, with no real plans to leave.
You’re in California for an indefinite period to recuperate from an illness.
Students from California who go to college out of state do not automatically become nonresidents. Likewise, attending school in California doesn’t automatically make a student a California resident. (You can see the rules here for how California determines residency status.)
Part-year resident status rules
Generally, you’re a part-year resident of California if you were a nonresident for some of the tax year. This is often the case for people who moved to California from another state.
If you’re a part-year resident, you pay California state tax on all income you received during the part of the tax year you were a resident of California, plus state income tax on income just from California sources while you were a nonresident.
Nonresident status rules
Nonresidents still may have to pay California state tax on income they receive from California sources. This means you may need to file a California state tax return even if you live in another state but made money from California-related things such as:
Services performed in California.
Rent from real estate you own in California.
The sale or transfer of real estate in California.
Income from a California business, trade or profession.
In some cases, you might be a nonresident for tax purposes even if you live in California but you were out of state for at least 546 consecutive days because of an employment-related contract. However, that exception won’t apply if you had more than $200,000 of intangible income while the employment-related contract was in effect, were in California for more than 45 days during the tax year, or if the state thinks the point of your absence is to evade state income taxes.
