Purpose of this form: Use this form to request an extension of time to file and pay the Commerce Tax. The taxpayer is automatically provided a six-month extension of time to file.This is an extension of time to file, not to pay. The State of Nevada does not impose an individual income tax so there is no need to request a state tax extension for filing a personal tax return. Six months is generally the longest amount of time allowed for an extension for filing taxes, though there are certain exemptions to this general rule. This can be done electronically, through the TurboTax Business software package; or you can fill out Form 7004 manually, and file it on paper. The clerk of the Supreme Court may grant one 7-day telephonic extension of time to file a fast track statement or response, upon a showing of good cause.
