New York Form DTF-4157, Complaint About New York State Tax Return Preparer, is a form used to report problems, misconduct, mistakes, or suspicious behavior involving a tax return preparer in New York State. This form helps a taxpayer, client, another preparer, or another person explain what happened, who was involved, which tax years were affected, and what type of complaint is being made. It can be used when a preparer may have failed to sign a return, refused to give back records, failed to provide a copy of a return, filed a return without permission, used false income or deductions, misused identifying numbers, stole or diverted a refund, misrepresented professional credentials, or created another problem connected to tax return preparation. The form asks for the preparer’s professional status, name, business details, phone number, email address, website, identification numbers, and the impacted tax years. It also gives the filer space to choose the complaint type, describe the facts, provide supporting information, and optionally include their own contact details. The purpose of the form is to give New York State enough information to review the complaint and understand the conduct being reported.
How To File New York Form DTF-4157
