New York Form DTF-686-ATT, New York Reportable Transaction Disclosure Statement and Request for a Determination, is used by taxpayers who need to disclose their participation in a New York reportable transaction or request a determination related to that transaction. A New York reportable transaction may include a listed transaction, a confidential transaction, or a transaction with contractual protection. The form collects key taxpayer details, the tax period involved, the name and type of transaction, information about entities connected to the transaction, fees paid to promoters or advisors, expected tax benefits, and the involvement of tax-exempt, foreign, or related parties. This form is important because it helps New York tax authorities understand whether a transaction created, changed, delayed, reduced, or avoided a tax result. Taxpayers may use it for disclosure purposes, protective disclosure, or to request a determination when they need clarity about how a transaction should be treated for New York tax purposes. Because reportable transaction rules can be complex, the information entered should be complete, accurate, and consistent with the taxpayer’s New York State tax return.
