[SabrinaD2]

To file a California S Corporation extension, you don't need to mail the form if you've already paid online. The extension is automatic.  You can make payments online using Web Pay for Businesses here

If you still need to mail the form, you can find the mailing address on the Franchise Tax Board's website.
