Why do companies have a fiscal year different from the calendar year?
I know some companies or entities have large incomes or expenses at certain times of the year, and like to close their books after these large events.  For example where I work,  the primary seasonal income comes after summer, so our fiscal year ends at the last days of October.  This gives the accountants enough time to collect all the funds, reconcile whatever they have to, pay off whatever they have to and get working on a budget for the next year sooner than a calendar year would. There also might be tax reasons.  To get all of your income at the beginning of your fiscal year, even if that is in the middle of the calendar year would allow a company to plan large deductible investments with more certainty.  I am not to sure of the tax reasons.
