Why are the tax due dates so close to Christmas and Income Tax filing?
These dates were established by the State of California. A single tax bill is payable in two installments to ease the taxpayers burden of making one large payment. These installments are due November 1st and February 1st. Penalties are incurred if the first installment is paid after December 10 and/or the second installment is paid after April 10. Both installments may be paid when the first installment is due. However, the second installment cannot be paid before the first installment is paid.
