How to File NYC Form 1127 for Business Changes

Businesses operating within New York City must inform the Department of Finance about significant changes to their operational or contact information. This is done by filing Form DOF-1, “Change of Business Information.”

Properly filing this document ensures that the Department of Finance has the most current data for your enterprise. This is important for receiving tax bills, notices, and refunds at the correct address. Maintaining up-to-date records helps prevent compliance issues, such as penalties from unreceived correspondence.

Triggering Events for Filing Form DOF-1

A business must file Form DOF-1 upon the occurrence of several specific events. The primary trigger for this filing is any change to the business’s legal name or the trade name (DBA) under which it operates. Any modification to the business’s official identification numbers also necessitates filing this form.

Changes to the physical location or mailing address of the business are common reasons for submitting Form DOF-1. This includes updating the primary business address or the billing address where the Department of Finance sends tax documents. A change in the business’s contact telephone number must also be reported.

The form is also used to report the cessation of business activities. If a business has permanently closed and filed its final tax return, this form can be used to communicate that status to the Department of Finance. This action helps to formally close out the tax account and prevent future tax notices.

Completing Form DOF-1

To complete Form DOF-1, a business must provide its Entity ID Number, which is the Employer Identification Number (EIN) or Social Security Number (SSN) used to identify the business tax account. This number is found on prior tax filings or any correspondence from the Department of Finance.

The form is structured to capture both the old information being replaced and the new information that should be on record. In the “OLD INFORMATION” section, you will enter the business’s trade name and identifying number as they currently appear in the Department of Finance’s system. This allows the department to locate the specific tax account that needs updating.

In the “NEW INFORMATION” section, you will provide the updated details. This could be a new legal or trade name, a new business address, a new billing address, or a new telephone number. The form also requires an authorized individual to sign, providing their title and the date of the submission.

Submitting the Form

Businesses can update their information either online or by mail. The most convenient method is to use the NYC Department of Finance e-Services portal. After creating a business profile online, you can directly change account information, view accounts, and make payments.

Alternatively, Form DOF-1 can be mailed to the New York City Department of Finance. It is advisable to make a copy of the completed and signed form for the business’s internal records before sending the original document.

The completed form should be mailed to the specific unit that handles these updates. The correct mailing address is: New York City Department of Finance, Entity Processing Unit – DOF-1, 59 Maiden Lane, 19th Floor, New York, NY 10038.

After the changes are submitted, the Department of Finance will update the business’s tax account records. The department typically does not send a direct confirmation that the changes have been made. Instead, the business will see the updated information reflected in future tax forms, notices, and other correspondence.
