How do I FIle an electronic extension for NY state taxes,? I have already filed an electronic extension for federal taxes

While the IRS requires you to file Form 4868 in order to request a tax extension, each state has its own requirements for obtaining a similar extension. Some states such as California offer automatic extensions to all taxpayers, while other states require you to file a specific form by the original due date of the return.
