September 1, 2017: The AICPA updated their state-by-state quick reference chart in March. All the links in this article have been updated to reflect the most current chart.
This year, the due dates for tax returns for C corporations with fiscal years ending other than June 30 have changed. The due dates are a month later than in the past.
This change has prompted many states to re-examine their due dates. The American Institute of Certified Public Accountants has released a new state-by-state quick reference chart of tax return due dates for C corporations that have a December 31 year end.
