Fiscal Deadlines

The standard Federal tax deadline if not using the Dec 31st year end date is 3.5 months after the end of the month where the tax year ends.

One exception- tax years that end in June have a Sept 15th due date. (June 30th is Australia's year end, so a lot of companies that have their US fiscal year match theirAustralian activities can be affected by this).

Common fiscal years - we also see are March 30th for UK related companies, and January 31st for tech companies that want to emulate Salesforce.

Dissolution: When companies close they use a fiscal year end date for their deadlines after the month they dissolve with the state.
