Refunds totaling almost $70 million may be waiting for thousands of Californians who didn't file a federal tax return in 2010.  

Almost 87,000 people may be eligible for refunds averaging over $500.  

In addition, many low-and-moderate income workers may not have claimed the Earned Income Tax Credit worth more than $5,600.  

To collect any of this money, a 2010 return must be filed by April 15th of this year.
