CALWORKS is the State Of California's welfare programs that gives money to needy people.
Yes, you can still do taxes if you're on welfare Calworks. Actually, anyone who resides in the USA is obligated to turn in an annual federal tax return.
Call or go to the DMV and I believe the payment is $5 to retrieve the form. *If you are on Calworks or PAES, you can contact your worker and ask them to write you a check for the DMV.
