The New York Trading Partner Agreement (TP-AG) is a contract between the New York State Department of Taxation and Finance and the trading partner who wishes to participate in the electronic filing of tax returns and payments. This agreement establishes the terms and conditions that the trading partner must adhere to in order to be part of the New York State Tax Electronic Filing program. This agreement covers a variety of topics related to the trading partner's obligations, including data security, data transmission requirements, and filing and payment deadlines. There are two types of New York Trading Partner Agreement: the standard TP-AG for all filing partners, and the advanced TP-AG for those participants who wish to use more advanced functionality such as batch processing.
