But that Arizona extensions is a full page, with four or five lines to fill out along with name, address and SSN.  Some people just really want to be consistent about doing everything online. Plus, postage is up to 60 cents, or maybe 63 if you don't buy it online.

Seriously, Arizona recognizes a federal extension when no tax is due, and this taxpayer has a federal extension, right?  So it's just a question of whether a disaster extension is included in that category.  

I also wonder whether a California resident is taxable by Arizona in the situation described here.
