Virginia gives everyone an automatic six-month extension for filing an income tax return. You don't need to file any form - the extension is automatic. The extension is for filing a return, not for paying the tax you owe. If you owe tax, it is still due by the original due date.
If you owe tax, mail in the extension payment voucher, Form 760IP , with your payment, by the original due date for filing the return to avoid penalties and interest. You can also make a payment online here .
If you are expecting a Virginia refund, you don't need to do anything. You have an automatic extension and you can file when you're ready.
