The New York ET-133 form serves as a crucial document for executors managing the estate of a deceased individual. This application allows for an extension of time to file or pay estate tax, addressing the potential complexities that can arise during the estate settlement process. Executors must provide essential information, including the decedent's name, social security number, and address at the time of death. Additionally, the form requires details about the executor, such as their name and contact information, as well as any authorized representatives involved. If the decedent was a nonresident, the executor must attach Form ET-141, the New York State Estate Tax Domicile Affidavit. The ET-133 also includes sections where the executor can explain their reasons for needing an extension, whether for filing or payment, and it emphasizes the importance of documentation to support these requests. The form must be submitted within nine months of the decedent's death to avoid penalties, and it is essential that executors follow the filing instructions carefully to ensure compliance with New York State tax laws.
