Automatic Five-Month Extension to File Form 65 - The Form 20E is no longer required to request an extension of time to file the Form 65. A five month extension of time for filing Form 65 will be granted automatically. However, the extension of time for filing the return is not an extension of time for payment of tax. The amount of tax due must be paid on or before the original due date of the return without considering the extension of time to file the return. Automatic Extension payments can be made using the Form BIT-V for Form 65. For other extension payment options, please see the Extension Payments page.
