• Calendar year filers whose taxable year ends on December 31, 2013.
• Fiscal year filers whose taxable year ends on June 30, 2013 and who are filing under Virginia's automatic six-month extension.

Virginia Automatic Extension Reminder: Virginia law provides for an automatic six-month extension from the original due date for filing. To take advantage of the automatic extension, the return must be filed on or before the end of the extension period. Please note: The automatic extension does not allow for additional time to pay any balance of tax due. Penalty and/or interest may apply to returns with a tentative tax due that was not paid by the original due date for filing the return. Also, the extension penalty may apply to returns that were filed during the extension period if less than 90 percent of the return's total tax liability was paid by the original due date.

For details regarding Corporation Income Tax extensions and penalties or for information on how to file and pay electronically, visit the Department of Taxation's Corporation Income Tax web page. Additional electronic filing information is posted on the Department's Corporate e-File web page.

Electronic Filing Mandate Reminder: All taxpayers who are subject to the Corporation Income Tax must file their estimated tax payments, annual income tax returns and final payments electronically. This includes Taxable Year 2013 returns, tax due payments and extension payments, as well as Taxable Year 2014 estimated payments. Taxpayers who wish to request a waiver of the requirement to file and/or pay electronically because of undue hardship should submit the Virginia Corporation Electronic Filing Waiver Request form.

Remember: It is very important that the Department maintains accurate information regarding taxpayer businesses. Many tax account updates can be performed through the Department's Business iFile system.
