(2) The tenant or tenants shall delete all social security numbers and income figures from all preprinted mailing labels or tax returns submitted. For any tenant or occupant who the tenant reports did not file a New York State income tax return for any applicable year, the tenant or occupant's name and address must be supplied on an appropriate form prescribed by the DHCR as it would have appeared had that tenant or occupant filed such return.
(3) The tenant or tenants shall provide the information to the DHCR within 60 days of service of the notice upon such tenant or tenants, which notice shall include a warning in bold faced type setting forth the requirement that failure to respond by not providing any information requested by the DHCR shall result in an order being issued by the DHCR providing that such housing accommodation shall not be subject to the provisions of the RSL and this Code. Section 2527.9 of this Title to the contrary notwithstanding, the tenant or tenants shall be required to retain proof of the delivery of such information to the DHCR, which proof shall consist of either, where delivery is made personally, a copy of the response with a timely DHCR date stamp acknowledging receipt, or where delivery is made by certified mail, a United States Postal Service receipt stamped by the United States Postal Service, or where delivery is made by regular first class mail, a United States Postal Service certificate of mailing stamped by the United States Postal Service; or as otherwise provided in an operational bulletin issued pursuant to section 2527.11 of this Title. Service shall be deemed to be complete upon mailing in accordance with section 2531.7 of this Part.
