a. Notwithstanding the provisions of section 6 of P.L.1990, c.61 (C.54:4-8.62) and section 3 of P.L.1997, c.348 (C.54:4-8.70) concerning the form and deadline of applications for the ANCHOR rebate program and the homestead property tax reimbursement, the director shall promulgate a single combined application form to be used by State residents to apply for the ANCHOR rebate program, the homestead property tax reimbursement program, and the Stay NJ property tax credit in accordance with the recommendations of the Stay NJ Task Force established pursuant to section 18 of P.L.2023, c.75 (C.54:4-8.75o). The combined application form shall, at a minimum, require the applicant to submit information about his or her age, annual income, homestead property address, as well as any other information determined necessary by the director in order to approve or disapprove the applicant's participation in those programs. The combined application form shall also advise the applicant that the director shall determine the eligibility of an applicant to receive an ANCHOR rebate, homestead property tax reimbursement, or a Stay NJ property tax credit. The director shall, for good cause shown, extend the time of any applicant to file an application for a reasonable period, and in such case, the application shall be processed and payment of an ANCHOR rebate, homestead property tax reimbursement, or a Stay NJ property tax credit made in accordance with the procedures established in the case of applications timely filed, except the date for the payment may be delayed for a reasonable period. If an applicant or an applicant's spouse has filed an application for an extension of time to file a gross income tax return, the date by which the applicant shall file an application may, in the discretion of the director, be extended for a reasonable period, and the date for the payment of an ANCHOR rebate, homestead property tax reimbursement, or a Stay NJ property tax credit may be delayed for a reasonable period. A State resident seeking property tax benefits under any of those programs shall accurately complete the entire application and file it with the director. For purposes of this subsection, in order to establish good cause to extend the time of an eligible claimant to file an application, the eligible claimant shall provide to the director either medical evidence, such as a doctor's certification, that the claimant was unable to file the claim by the date prescribed by the director because of illness or hospitalization, or evidence that the applicant attempted to file a timely application. Except as may be established by medical evidence or inability to file a claim, good cause shall not be established due to a claimant not having received an application from the director.
