Virginia Automatic Extension Reminder: Virginia law provides for an automatic 6-month extension from the original due date for filing for individual taxpayers, corporations filing Form 500, and pass-through entities filing Form 502. In order 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.

Electronic Filing Mandate Reminder: All taxpayers that 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 subject to the Corporation Income Tax that are seeking a waiver of the requirement to file and/or pay electronically due to 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.
