Personal Taxes

We give you an automatic 6-month extension to file your return. You must file by the deadline to avoid a late filing penalty.


An extension to file your tax return is not an extension to pay. Pay the amount you owe by April 15th to avoid penalties and interest. Some areas may have a later deadline. Click the link above to confirm. 

Make a payment

Use Payment for Automatic Extension for Individuals (FTB 3519) to make a payment by mail if both of the following apply:

  • You cannot file last year's tax return by April 15 of this year
  • You owe tax for last year

To pay electronically, visit our payment options.
