Do I file a California tax return to report a gain on a house sale under $250,000? I got form 1099-S and already filed the federal return, where I excluded the full gain.

I met all the conditions for the federal gain exclusion amount of $250,000.  I ended up with zero taxable income on the federal return, as I had no other taxable income.  I just need to know if a California return is required.

Since you received a 1099-S you have to report that sale on both your federal and California returns even though California conforms to federal rules regarding the capital gain exclusion so you will owe no tax.   Your returns merely tell the taxiing authorities that you qualify for the exclusion.
