Many communities have, however, supplemented the basic code by requiring a minimum 30 door opening in most rooms, 24 for bathrooms, at least one 36 exterior door, and a minimum door height of 6'-8 (80).
Illinois will automatically grant all taxpayers a six-month extension of time to file Form IL-1040. For calendar year filers, the filing date is automatically extended to October 15. You are not required to file Form IL-505-I in order to obtain this automatic extension.
The extension of time to file does not extend the due date for payment of any tax due. Extensions are granted only upon the timely filing of the extension with any required payment amount. If you prefer not to request an extension over the Internet, you may file a paper Form M-8736.
