Monday is the deadline for filing personal income tax returns for 2015 to avoid penalties.
Each year, taxpayers are allowed to extend the April 15 filing date without penalty as long as they pay what's due to the federal and state governments by that April date.
In California, the state's Franchise Tax Board estimates that of the more than 18 million personal income tax returns due, more than 1.5-million taxpayers have taken advantage of the state's automatic six-month filing extension.
“We encourage everyone to file a state return, especially working families who never had to file before and might be leaving hundreds of dollars on the table,” said State Controller Betty T. Yee, who serves as chair of the FTB.
Many taxpayers can file a return electronically free of charge.
Visit FTB’s website at www.ftb.ca.gov for a list of both free or fee-based e-file service providers.
As of October 10, Californians filed more than 17 million personal income tax returns, 14.8 million of them electronically. The state has issued 11.2 million refunds totaling more than $10.6 billion.
