Larry is an accountant working for LZA Inc., a C corporation, and he prepares the corporate tax return. He is certain that he will not be able to finish the return in time to file by the due date. LZA has a fiscal tax year, which ends on July 31. For the current tax year, assume the due date does not fall on a Saturday, Sunday, or legal holiday. This is a four-part question. 

Question 1: What is the due date (month and day) for LZA's corporate income tax return? 

Question 2: What form should Larry file to obtain an extension of time to file LZA's corporate return? 

Question 3: What is the due date (month and day) to file the form for extension of time to file? 

Question 4: How long does the extension of time to file extend the filing due date
