i would suggest revisiting your W2 and delete the entry in Box 14 where your SDI is reported. California State Disability Insurance (SDI) benefits are generally not taxable, either on a federal level or on a state level. In fact, they are never taxable, except when considered to be a substitute for unemployment compensation, and when paid to an individual who is ineligible for Unemployment Insurance (UI) benefits only because of the disability.
