I would like help clarifying the disaster extension below.  My reading of the IRS/FTB notices tells me that our original due date for filing and paying taxes was moved from April to October, which then implies that a taxpayer can file for a 6 month extension after the fact (Making the extended deadline April 2024). Am I interpreting this correctly?
