I have not received anything from the State of California regarding my state disability payments. Are these funds taxable income?

If the state disability income is your ONLY source of income,it is probably NOT taxable.

My only other income source than ca state disability is regular social security Mighty slim pickins Are either taxable
Now just received 1099c debt cancellation for credit 27000 dollars with lots of debts and no assets Is this a taxable asset

The disability and Social Security income by themselves are NOT taxable,

However, the discharged debt on that Form 1099-C IS considered taxable income, and it likely will make the SS income and perhaps the disability taxable as well.
