For part-year and nonresident returns, activities with postal code
CA
that are not allocated using the state allocation spreadsheet include 100 percent of income and expenses in the
California Sources
calculations. Activities with any other postal code exclude all income and expenses for the
California Sources
calculations. When data is entered into the state allocation spreadsheet, California Sources amounts are calculated by multiplying the total income and total expenses by the entry in the
Percent of federal allocated to state
field in the federal St CO Screen with postal code
CS
(California Source). Schedule R is available in the California Non Calculating folder to calculate the instate percentage.
