The income of a partner who is a part-year resident during any part of its own or the partnership’s taxable year shall compute his or her income in two distinct periods:
Period as a California resident - California taxes income and deductions realized from all sources.
Period as a California nonresident - California only taxes gross income and deductions realized from sources within this state
so if this is a California partnership, you would be taxed on 100% of the income (unless it provides a state allocation schedule)
if it is not, you could allocate the income based on the number of days you were a Ca resident
