It depends. California has specific rules for taxing trust income, and apportionment depends on factors like trust residency, fiduciary location, and income source. Generally, California taxes all income from California sources, regardless of where the trustee resides.
Once you prepare the return, a K-1 will be generated to you, which will report the trust's income for you to report on your own personal tax return. On your own return, you can prorate the taxable income reported on the K-1 based on the days you lived in California.
